Installation

Lifting Recommendations Before preparing the unit for lifting, estimate the approximate center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly distributed. Approximate unit weights are given in Table 1.

must be capable of lifting the unit weight with an adequate safety factor.

The use of under-capacity lifting devices may result in severe personal injury or death and can seriously damage the unit.

The crated unit can be moved using a forklift of suitable capacity. For lifting the unit, attach lifting straps or slings securely to the lifting holes at each corner. Use spreader bars to protect the unit casing from damage. Test lift the unit to determine proper balance and stability.

Clearances Provide enough space around the unit to allow unrestricted access to all service points. Refer to unit dimensional data for minimum required service and free air clearances. Observe the following points to insure proper unit operation.

A. Do not install the unit under a low overhang. Condenser discharge clearance is not less than 2.5 mm.

Important: Do not obstruct condenser discharge air. This can result in warm air recirculation through the coil.

B. Do not locate the unit in a position where runoff water can fall into the fan discharge openings.

C. Condenser intake air is supplied from three sides of the unit. Adhere to the minimum required clearances given in dimensional data.

Unit Mounting “For ground level installation, the unit base should be adequately supported and hold the unit near level. The installation must meet the guidelines set forth in local codes.”

The support should extend two inches beyond the unit base channels at all points. The unit and support must be isolated from any adjacent structure to prevent possible noise or vibration problems. Any ground level location must comply with required clearances given in dimensional data.

Warning: On-sight lifting equipment

Caution: Use spreader bars to prevent lifting straps from damaging the unit. Install bars between lifting straps. This will prevent the straps from crushing the unit cabinet or

Refrigerant Piping Guidelines

Refrigerant Piping To ensure the return of oil in the refrigerant lines, it is necessary to follow these recommendations:

1. Select the tube lengths with care

DQG�WU\�WR�DYRLG�KDYLQJ�D�¿QDO�IHZ

meters of tube to use up. Refer to table 2 for tube sizes.

2. Pitch all horizontal suction lines down towards the unit to assist gravity oil drainage back to the compressor.

3. Avoid creating large oil traps in horizontal suction lines as this will reduce oil circulating in the system and may eventually lead to failure of the compressor.

4. A small oil trap at the end of a horizontal suction line before a long vertical riser (of more that 2.5 metres) has the advantage of assisting the high velocity gas to carry the oil up the vertical pipe.

5. Liquid lines require no special installation techniques as the liquid refrigerant R-22 and the oil mix.

The densities of the refrigerant and oil are near enough the same so any movement of liquid refrigerant will carry oil with it.

6. The installation of a liquid line sight is recommended. It is very useful during the maintenance procedures.

Refrigerant Piping Guidelines A. Maximum recommended line lengths: (per circuit) Maximum linear length 200 Ft.

(W/o accumulator) Maximum suction line lift 60 Ft.

Maximum liquid line lift 60 Ft.

B. Maximum allowable pressure drops (R410A):

Suction line 14 psi.

Liquid line 65 psi.

Refrigerant Charging and Evacuation

Note: Each TTA unit ships with holding charge.

System Evacuation

1. After completion of leak check, evacuate the system.

2. Attach appropriate hoses from manifold gauge to gas and liquid line pressure taps.

Note: Unnecessary switching of hoses can be avoided and complete evacuation of all lines leading to sealed system can be accomplished with manifold center hose and connecting branch hose to a cylinder of R-22/R407C and vacuum pump.

3. Attach center hose of manifold gauges to vacuum pump.

4. Evacuate the system to hold a 350 micron (-76 cm.Hg) vacuum.

5. Close off valve to vacuum pump and observe the micron gauge.

If gauge pressure rised above 500 microns in one (1) minute, then evacuation is incomplete or the system has a leak.

6. If vacuum gauge does not rise above 500 microns in one (1) minute, the evacuation should be complete.

Caution: Do not connect a dual-circuit outdoor unit to a single circuit evaporating unit. (blower)

Operating Pressure (PSI)

125 - 140

Hi 365 - 418

Pressure reading should fall approximately at the points shown by the pressure curves in Service Facts. Add or remove refrigerant (gas only) as required to obtain correct head and suction pressure.

Check suction line superheat and condenser sub-cooling to ensure the unit is operating properly.

4. Disconnect all power to the unit.

5. Remove the charging system from the unit and close the opening in the bottom of the control box with the pivotal cover before attempting to replace access panel.

6. Replace all panels.

Additional Charge Refrigerant suitable for a tube length of 12 to 25 feet is recommended in Table 3. When the tube is longer than 25 feet, additional charging is necessary. For the additional amount, using the table 4 for recommended amounts:

Caution .Freon Gas only Always evacuate air from the tubing before adding refrigerant.

Add refrigerant through the charging port of liquid line valve after the completion of evacuation.

The refrigerant provided by the manufacturer meets all the requirements of our units. When using recycled or reprocessed refrigerant, it is advisable to ensure its quality is equivalent to that of a new refrigerant. For this, it is necessary to have a precise analysis made by a specialized laboratory. If this condition is not respected, the manufacturer’s warranty could be cancelled.

Operation

Sequence of Operation General Operation of the system cooling cycles is controlled by the position of the system switch on the room thermostat.

Evaporator Fan (Indoor Supply Air) The evaporator fan is controlled by an ON/AUTO switch on the room thermostat. With the switch positioned at AUTO and the system operating in the cooling mode, fan operation coincides with the cooling run cycles.

When the fan switch is positioned at ON, fan operation is continuous.

Cooling Mode With the disconnect switch in the “ON” position, current is supplied to the compressor crankcase heater

(s) and control transformer. The crankcase heater (s) supplies heat to the compressor (s) during the “OFF” cycle. With the room thermostat system switch positioned at COOL and the fan switch at AUTO, the compressor contactor energizes on a call for cooling. When the contacts of the compressor contactor energizes on a call for cooling. When the contacts of the compressor contactor close, operation of the compressor and condenser fan begins.

The evaporator fan contactor also energizes on a call for cooling and initiates evaporator fan operation.

On dual circuit units, when second stage cooling is required, Y2 from the indoor thermostat will energize 2nd compressor.

Note: With the thermostat fan switch in the ON position, the evaporator fan will operate continuously, regardless of compressor or condenser fan operation.

Safety Controls Note: All of these controls may not be installed on your unit, check electrical schematic.

Low Pressure Cut-Out (LPCO) This control’s sensor is located in the suction (gas line, near the compressor).

This control will stop the compressor and the outdoor fans in suction pressure drops below the Low Pressure Cut-Out setting.

High Pressure Cut-Out (HPCO) This control’s sensor is located in the liquid line. This device will shut off the compressor and the outdoor fan (s) if the discharge pressure exceeds the High Pressure Cut-Out’s setting.

Internal Overload Protector (IOL) This device is a current/thermal actuated warp switch, imbedded in the compressor motor windings.

If will shut off the compressor if the temperature or current of the compressor motor windings exceeds its design trip temperature.

Note: The IOL will put the compressor back in operation once the compressor motor heat has dropped below the trip setting;

however, a check of the refrigerant and electrical systems should be made to determine the cause and be corrected.

Installation Checklist Complete this checklist once the unit is installed to verify that all recommended procedures have been accomplished before starting the system. Do not operate the system until all items covered by this checklist are complete.

• Inspect unit location for proper required service clearances.

• Inspect unit location for proper free air clearances.

• Inspect unit location for secure.

Level mounting position.

Refrigerant Piping

• Performed initial leak test?

• Connected properly sized and constructed liquid and suction lines to the connection stubs at both the indoor and outdoor units?

• Insulated the entire suction line?

• Insulated portions of liquid line exposed to extremes in temperature?

• Charge each circuit with proper amount of R-22/R407C?

Electrical Wiring

• Provided unit power wiring (with disconnect) to proper terminals in the unit control Section?

• Installed system indoor thermostat?

• Installed system low voltage interconnecting wiring to proper terminals of outdoor unit, indoor unit and system thermostat?

Unit Start-Up Once the unit is properly installed and pre-start procedures are complete, start the unit by turning the System Switch on the indoor thermostat to either COOL or AUTO. The system should operate normally.

the indoor air handler is closed before operating the system. Operating the outdoor unit without the indoor fan energized, can cause unit trip-out on high pressure control and/or liquid
