Step 1: Foundation, Vibration Isolation, Elevation, Clearances, Transportation

Foundation

• The OPC unit must be installed on a level concrete foundation, level roof curb, or level perimeter beam system.

• Comply with local codes for proper anchoring and vibration isolation.

• Use of a level roof curb or perimeter beam system requires the specifying engineer to identify all necessary materials of construction, thickness, and additional bracing or supports.

• See the diagrams below for mounting hole locations.

• Point load at each mounting location is 200 lbs or less.

Page 5 of 19 Effective Date: 16 April 2022 Revision: 11

Vibration Isolation

• The chiller does not require vibration isolation on the mounting for the chiller to operate normally.

• The motors in the chiller are hard mounted to the metal structure of the chiller. They are not internally isolated.

• It is common for the chiller to be hard mounted directly to a pad on grade, roof curb, or perimeter beam system.

• If vibration transmission to the building structure is a concern, an engineer should provide a detailed specification for vibration damping.

• There are two common approaches o Rubber or synthetic pads between the chiller and the mounting o Spring vibration isolators. These cannot be installed directly between the chiller and the mounting. The chiller must be mounted on a perimeter beam. The spring vibration isolators can be installed between the beam and the mounting.

• If OSHPD compliance is required and isolators are used, the spring isolators must comply with Haskris OSHPD

OSP-0673 file.

Elevation

• If the chiller is located at a higher elevation than the MRI, the maximum recommended height difference is

100 ft (30.5 m).

o The maximum height difference is based on several factors including the maximum inlet water pressure for the MRI, normal water pump discharge pressure, and pressure losses in the piping to the MRI.

o Consult Haskris (847-956-6420) if the height difference needs to be more than 100 ft (30.5 m).

• If the chiller is located at a lower elevation than the MRI, the maximum recommended height difference is

100 ft (30.5 m).

o It is best if the height difference can be less than 32 ft (9.8 m).

o Consult Haskris (847-956-6420) if there are questions.

Page 6 of 19 Effective Date: 16 April 2022 Revision: 11

Clearances

• See the diagrams below showing recommended clearances.

• Air flow is horizontal into the unit and vertical out of the unit.

• Maintain an unobstructed space for free air discharge above the OPC unit.

• Consult Haskris (847-956-6420) if clearances will be smaller than these recommendations. Haskris will evaluate individual site conditions as needed to ensure proper operation.

• Avoid areas where a heat source will discharge heat towards the OPC unit.

o Examples: condenser vents, heating exhaust, etc.

• Avoid areas where debris may accumulate on the condenser.

OPC24 Clearance Recommendations

Page 8 of 19 Effective Date: 16 April 2022 Revision: 11

OPC36 Clearance Recommendations

Transportation

• Transport the OPC unit using the fork pockets or rigging lift points. Ensure forks are past the chiller center post.

• If rigging the unit, lift only from the points shown below. Proper rigging technique (including spreader bars) is critical to avoid damaging the unit.

• Do not remove any panels from the unit during the rigging process.

• See below for rigging and lift points and center of mass.

Step 2: Line Sizing, Piping Details

Line Sizing

• Haskris is available to review pipe runs, pressure drop, etc and make recommendations for individual sites.

Call 847-956-6420.

• If the total straight pipe length is less than 450 ft (137.2 m) use 1-1/2” nominal pipe size.

• If the total straight pipe length is less than 1,800 ft (548.6 m) use 2” nominal pipe size.

• If the total straight pipe length is greater than 1,800 ft (548.6 m) consult Haskris for assistance.

Piping Details

• Comply with local codes for proper piping.

• Use type L copper piping and non-ferrous materials.

• Insulate piping to minimize condensation.

• Terminate the beginning and ends of hard runs with vibration isolators.

• Ensure piping is clean and free of flux at solder joints.

• Install manual ball valves at high points in the system for purging air while filling the lines. If automatic purge valves are used, isolation ball valves should be installed before the purge valves. Purge valves must be closed during normal operation.

• Install drain valves at the base of every rise for emptying the lines.

• Install a heat trace on piping exposed to temperatures below +20°F (-6.7°C). Cover heat trace with closed cell UV resistant insulation. Power the heat trace from a dedicated disconnect.

• Label supply and return lines over insulation with arrows indicating flow directions.

• Install isolation ball valves on inlet and outlet connections at the Siemens separator.

• Install isolation ball valves on the supply and return connections at the chiller.

• Install flush ports with isolation valves after the supply and return ball valves.

• Sleeve and insulate pipe penetrations through all roof and/or walls.

• Install a loop of reinforced opaque hose between supply and return connections in equipment room for flushing.

• After the lines are flushed, connect the lines in the equipment room to the Siemens separator.

Page 15 of 19 Effective Date: 16 April 2022 Revision: 11

• Units include a phase monitor. Refer to the fault indicators provided on the phase monitor and contact a licensed electrician to correct any faults.

• Electrical power must be applied to the unit at least 12 hours in advance of start-up. This energizes the crankcase heater and drives out any accumulated liquid refrigerant in the compressor.

Remote Control Panel

• A remote control panel is provided with the Haskris OPC unit.

• Mount the remote control panel on a wall indoors. See the templates on the next page.

• Standard units include a 150 ft cable to connect this remote control panel with the Haskris OPC unit. The cable is inside the unit. Use the plug provided on the cable to connect the remote control panel to the OPC unit.

• Optionally, some units may include a longer cable. The cable is inside the unit. The remote control panel is mounted on an electrical box that should be mounted on the wall. Connect the three wires on the cable to

#2 (GND), #3 (TX -), and #4 (RX +) inside the box. Connect the box to 115V electrical from a wall outlet.

Step 4: Piping Flush and Purge

Piping Flush

An external water source is required to flush the piping.

1. Close supply and return ball valves.

2. Remove caps from flush ports and connect external water hose to each flush port.

3. Flush piping with external water until water runs clear.

4. Close return side flush valve and apply 100 psi gas for 30 minutes to check for leaks.

5. Repair any leaks and perform flush again.

Piping Purge

1. After a successful leak check, open all drains including those installed on piping rise.

2. Use compressed air or nitrogen to eliminate water from lines.

3. Close all drains and purge isolation valves.

Page 18 of 19 Effective Date: 16 April 2022 Revision: 11

Step 5: Preparing Glycol Mixture, Filling

Prepare Glycol Mixture

• Use potable distilled water.

• Use pure, lab-grade glycol. Haskris strongly recommends propylene glycol. Ethylene glycol is acceptable but not recommended because it is toxic.

• Use refractometer to verify glycol mix percentage (35-40%).

• Provide an extra supply of glycol mixture to replenish the reservoir during the start-up.

Fill the Reservoir

1. Close supply and return ball valves.

2. Remove the cap from the top of the reservoir.

3. Fill the reservoir with glycol mixture.

4. Replace cap after filling.

Fill the Piping

1. Verify supply and return ball valves are closed.

2. Remove cap from supply flush port and connect fill hose. Connect the other end of the hose to external fill pump.

3. Remove cap from return flush port and connect hose. Place the other end of hose in a large bucket. This will act as a vent when filling piping with glycol mix.

4. Open the return side flush valve and energize external fill pump to fill piping with glycol mix.

5. Stop filling piping when glycol solution begins to drain from return flush port.

6. Close both supply and return flush valves, deenergize external fill pump, and replace caps.

7. Open both supply and return ball valves.

Page 19 of 19 Effective Date: 16 April 2022 Revision: 11

Step 6: Final Checks

Phase Monitor

• If the voltage and phase from the service disconnect is correct, the phase monitor should have a solid green LED.

• If the phase monitor has a solid or flashing red LED, contact a licensed electrician to correct the fault.

Controller Faults

• Press the button on the controller.

• The screen should say NO ALARMS.

• If any faults are described, consult Haskris (847-956-6420) to resolve these.

I. Startup

Phase Monitor

Purpose: The chiller has a phase monitor to check incoming electrical power.

Operation: The phase monitor is factory adjusted by Haskris according to the proper electrical settings for the chiller. Do not adjust the knobs on the phase monitor without discussion and approval from Haskris.

The phase monitor will show a solid green LED if the voltage and phase from the service disconnect is correct (Figure 1). If the phase monitor has a solid or flashing red LED, contact a licensed electrician to correct the fault (Figure 2).

• Reversal is caused by the 3 lines being in an improper sequence. To correct a reversal, switch any 2 of the 3 line connections. Make this switch at the disconnect, not in the chiller.

• Loss/unbalance is caused by a percentage difference in voltage between the 3 lines relative to each other.

• Undervoltage is caused by a percentage difference in voltage between the 3 lines compared to the line-line voltage knob setting.

• Overvoltage is caused by the voltage between the 3 lines being >10% over the line-line voltage knob setting.

Figure 1: Phase monitor

Figure 2: Phase fault LED status patterns

Page 4 of 19 Effective Date: 14 October 2021 Revision: 03

ON/OFF Switch

Location: The chiller has a rotary ON/OFF switch located on the outside of the low voltage box with the main controller (Figure 3).

Operation: Rotate the switch to make the chiller run when in the ON position (horizontal) or stop when in the OFF position (vertical). If a fault occurs, turning the switch to OFF and then back ON will reset the fault.

Figure 3: ON/OFF switch, vertical position

Page 5 of 19 Effective Date: 14 October 2021 Revision: 03

Pump Priming

Purpose: All fluid is removed from the pump head prior to shipment from Haskris. When starting the pump, it needs to be filled with fluid. This process is called priming the pump.

When the tank is full, the pump suction line is “flooded”. In some cases, this flooded suction will automatically prime the pump. When the chiller is turned ON, the pump will run. If the controller display shows the pump generating pressure, then the pump is primed.

If the controller display shows a low pressure <10 psi, then the pump did not automatically prime.

Follow the procedure below.

1. Identify the priming plug on the face of the pump head (Figure 4)

2. Use a 10mm hex or Allen wrench to loosen the priming plug slightly. The plug should remain threaded into the port, but air and liquid should be able to escape.

3. Allow air and a small amount of fluid to escape

4. Tighten the priming plug

Figure 4: Pump priming plug circled

Page 6 of 19 Effective Date: 14 October 2021 Revision: 03

Pump Supply Pressure

Purpose: The chiller uses a centrifugal pump. For the pump to run properly it needs some restriction in the piping system to push against the pump and generate pressure. If this does not happen the chiller may stop and give a fault. To correct this, follow the procedure below.

1. Identify the ball valve inside the chiller on the return line. The handle of the ball valve has been removed and it may be wrapped in insulation (Figure 5 and 6).

2. Start by closing this valve approximately halfway so it is at a 45° angle

3. Cycle the ON/OFF switch on the chiller

4. Observe the pump supply pressure on the controller display

5. If the pump pressure is <50 psi, close the ball valve further. The target pump supply pressure is 55-65 psi.

6. Continue cycling the ON/OFF switch and adjusting the valve until you achieve this target

III. Chiller Features

Cellular Communication and Remote Monitoring

Purpose: The chiller uses a cellular connection to allow Haskris to remotely view the controller for diagnostics and addressing issues in the field. Haskris can receive alerts if there are faults.

Method: The chiller has a cellular modem and uses 2 antennas to communicate with the cell towers.

Separate Independent Refrigeration Circuits

Purpose: The chiller has identical, parallel refrigeration circuits to enhance uptime.

Notes: If one of the refrigeration circuits has a fault, the other(s) can continue running. All circuits have adequate capacity to keep the magnet cold on their own, so the magnet can continue to have proper cooling while service or repairs are being performed.

Redundant Primary/Standby Pumps

Purpose: The chiller has 2 identical pumps for a fully redundant pumping system to enhance uptime.

Operation: During normal operation, the pumps switch back and forth on a schedule to distribute run time. In case of a failure with the primary pump, the standby pump will take over and circulate the water/glycol for the MRI. Both pumps have suction isolation valves for easier replacement which minimizes downtime.

Additional Sensors

Purpose: The chiller has additional pressure and temperature sensors that are used for improved real-time diagnostics.

Page 17 of 19 Effective Date: 14 October 2021 Revision: 03

Remote Control Panel

Purpose: The chiller includes a remote control panel which can be installed indoors in the MRI equipment room. This provides a convenient way to interact with the chiller indoors.

Operation: This is a direct mirror of the controller in the outdoor chiller. Any changes done on the remote control panel are immediately reflected on the chiller. For example, if someone changes the set point on the remote control panel, the chiller will reflect this change.

See the Installation Instructions for details on mounting and wiring.

E-coated Condensers for Corrosion Resistance

Purpose: The condensers that are installed on this chiller have an e-coating. This coating protects the condenser from corrosion. This is particularly important in coastal areas with salty ocean air.

Louvered Hail Guard Panels

Purpose: The chiller includes panels to protect the condensers from hail damage. The panels have louvers to allow airflow while blocking hail.

Page 18 of 19 Effective Date: 14 October 2021 Revision: 03

Energy Saving eco Mode

Purpose: When the chiller is under a reduced load, the chiller will use fewer refrigeration circuits to provide cooling to reduce power consumption.

Operation: When the chiller is in eco mode, the status on the display will say “ON eco” (Figure 17).

The controller initiates eco mode based on the operation of the hot gas bypass valves and the refrigerant head pressure.

IV. Maintenance

Frequency

Notes: Approximately every 6 months the chiller should be inspected, and preventative maintenance should be performed. Use the Haskris provided Preventative Maintenance checklist.

Glycol Mixture

Purpose: The unit is designed to circulate a mixture of potable distilled water and pure glycol. This glycol is intended to help resist freezing water.

Notes: The full level in the tank is marked on the side of the tank. If the level falls, replenish the tank as needed until the tank remains full. Use a refractomester to verify glycol mix percentage (35-40%).

If the glycol mix is visibly dirty or contaminated flush the glycol from the whole system and refill with a fresh glycol mix.

Figure 15: Eco mode active

Page 19 of 19 Effective Date: 14 October 2021 Revision: 03

Wye Strainer

Purpose: A wye strainer is installed inside the chiller on the return line to catch particles in the fluid

(Figure 16).

Operation: If the return pressure is above 15 psi, clean the wye strainer. The chiller will give a fault if the return pressure is too high, but the chiller will stay running.

Condenser Coils

Notes: Dust and debris may collect on the condenser during normal operation. Accumulated debris restricts air flow and reduces heat transfer which affects chiller performance. Use a brush to loosen compacted debris and use a vacuum to collect the debris.

Electrical Inspection

Notes: Use a multimeter to check electrical values. Take measurements at contactors or terminal blocks. Compare values to the chiller or component name plate. Units include a phase monitor. Refer to the fault indicators provided on the phase monitor and contact a licensed electrician to correct any faults.

1. Engineer’s Note #1

a. Network Controllers NC-1 and NC-2 will communicate to existing front-end via

BACnet. Front-end graphics to be generated by Johnson Controls.

2. Engineer’s Note #2

a. “Modified Equal Percentage” is a combination Linear/Equal Flow Percentage characteristic offering typical linear flow characteristic at low end of valve position with typical equal percentage flow characteristic at higher end of the valve position;

providing a more linear heat transfer from the valve/coil combination over the entire valve range. Refer to “Flow Characteristic” chart that follows.

3. Engineer’s Note #3

a. Valves to be bronze body.

4. Steam convector details on drawing M502 indicate a 5 PSIG steam supply to convectors;

specification 230923, item 2.14.E.6.b states modulating steam control valve pressure drop to be 80% of inlet gauge pressure for steam pressure up to 15 PSIG (4 PSIG pressure drop with 5 PSIG inlet pressure), convector schedule on drawing M601 and convector submittal indicates convectors sized based on an inlet steam pressure of 5 PSIG.

a. Submitted steam control valve based on a maximum 1 PSIG steam pressure drop to provide a 4 PSIG steam inlet pressure at the convector under full load.

5. 2-Pipe fan coil unit control detail on M601 shows cooling coil valve being Normally Open and steam convector heating coil valve being Normally Closed.

a. Submitted control valve actuators are Fail-in-Place. Fail-in-Place actuators are preferable in this application since neither the fan coil unit nor the convector are ducted to outside air. Having the valves remain in current state when there is a power outage is preferable to forcing valves open or closed when power is turned off.
