1.0 INTRODUCTION

1.1 System Descriptions

Deluxe System/3 12 to 60 ton Chilled Water environmental control system is available in several con-figurations. Each configuration can operate with either Advanced Microprocessor Controls (AM), or Advanced Microprocessor Controls with Graphics (AG). A brief description of each, including opera-tional differences, can be found below. Check model numbers to see what is supplied with your unit.

1.1.1 Chilled Water Systems

Cooling

These systems utilize a central chiller and control cooling by modulating a control valve in the chilled water line.

Heating

Three stages of electric reheat standard; steam/hot water optional

Humidification

Infrared standard; steam grid and steam generating optional

Dehumidification

Chilled water valve opens proportionally in response to room needs

2.0 INSTALLATION

2.1 Room Preparation

The room should be well-insulated and must have a sealed vapor barrier. The vapor barrier in the ceiling can be a polyethylene film type. Use a rubber-base or plastic-base paint on concrete walls and floors. Doors should not be undercut or have grilles in them.

Outside, or fresh, air should be kept to an absolute minimum. Outside air adds to the heating, cooling, humidifying and dehumidifying loads of the site. It is recommended that outside air be kept below 5% of the total air circulated in the room.

2.2 Location Considerations

For a downflow unit, the unit can sit on an accessible, elevated flooring system. It may be necessary to furnish additional pedestal support below the unit to ensure maximum structural support. A separate floor stand for the unit may be used as support, independent of the elevated floor and installed prior to the flooring system.

For downflow and upflow units, provide approximately 34" (864 mm) service clearance on the left, right and in front of the unit whenever possible. The minimum space required for service is 18" (45.7

cm) on the left end, 18" (45.7 cm) on the right end, and 24" (61 cm) in front of the unit. This space is necessary to permit routine maintenance, such as replacing filters, adjusting the fan speed and clean-ing the humidifier. On downflow chilled water units and upflow 599C, 600C, 735C and 740C models, left- and right-end minimum clearances are 0" (0 cm), with the exception of rear return.

Avoid locating units in an alcove or at the extreme end of a room that has a high aspect ratio (long narrow room). Also avoid locating units too close together. This tends to reduce the effectiveness of the air distribution as compared to units located 30-40 feet (9-12m) apart.

NOTE

If high efficiency 6" filters are used, 25" (63.5 cm) clearance on the right end is required for removal and replacement of filters.

2.4 Piping

All fluid and refrigeration connections to the unit, with the exceptions of the condensate drain and live steam, are sweat copper. Factory-installed piping brackets must not be removed. Field-installed piping must be installed in accordance with local codes and must be properly assembled, supported, isolated and insulated. Avoid piping runs through noise-sensitive areas, such as office walls and con-ference rooms.

Refer to specific text and detailed diagrams in this manual for other unit-specific piping require-ments.

2.4.1 Drain Line

A 3/4" NPT (1-1/4" NPT on 599C, 600C, 739C and 740C) is provided for the evaporator coil condensate drain. This drain line also drains the humidifier, if applicable. The drain line must be located so it will not be exposed to freezing temperatures. The drain should be at least the full size of the drain connec-tion and pitched a minimum of 1/8" per ft. (11 mm per meter).

2.4.2 Piping Considerations for Raised-Floor Applications

All piping below the elevated floor must be located so that it offers the least resistance to air flow.

Careful planning of the piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the subfloor, it is recommended that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes should be run parallel to the air flow.

NOTE

This line may contain boiling water. Use copper or other suitable material for the drain line.

The unit is shipped from the factory with an internally-mounted trap. No external trap is required. The drain line must comply with all applicable codes.

The unit is shipped from the factory with a condensate pump installed. The condensate pump discharge (drain) line must comply with all applicable codes.

The unit is shipped from the factory with the condensate pump option, unmounted in the unit, which must be installed in the field. The unit has an internally mounted trap. The drain line from the unit to the condensate pump does not require a trap. The discharge (drain) line from the pump must comply with all applicable codes.

2.5 Electrical Connections

Three-phase electrical service is required for all models in either 208, 230, 460 or 575 V, 60 Hz; or 200, 230 or 400 V, 50 Hz. Electrical service shall conform to national and local electrical codes.

Install a manual electrical disconnect switch within 5 feet (1.6 m) of the unit in accordance with codes. A factory-supplied disconnect switch may be factory-mounted within the unit and accessible from the exterior.

2.6 Air Distribution Considerations

2.6.1 Raised-Floor Air Flow Distribution Considerations

To ensure proper air distribution, any unusual restrictions within the air circuit must be avoided. For under-floor air distribution, observe the following guidelines:

Select the air supply grilles and perforated panels for the raised floor to ensure minimum loss of pres-sure in the circuit. Air volume dampers on grilles, which extend several inches below the surface of the raised floor, are usually detrimental to airflow. Consideration of the height of the damper on the grille in conjunction with the floor height will determine whether this type of grille may be used.

The grilles used in raised floors vary in size, the largest being approximately 18" x 6" (457 x 152 mm).

A larger grille size would be detrimental to the structural capacity of the raised floor panel. An 18" x 6" (457 x 152 mm) heavy-duty pencil proof type grille typically has 56 square inches (0.036 m2) of free area. Perforated panels are available from various manufacturers of raised floors. These panels are usually 2' x 2' (610 x 610 mm) square and have a nominal free area of approximately 108 to 144 square inches (0.07 to 0.09 m2). Use caution in selecting perforated panels as some manufacturers have only 36 to 40 square inches (0.023 to 0.026 m2) of free area, requiring four times as many panels.

Avoid floor elevations below 7-1/2" (190.5 mm), loosely installed flooring systems, and below-floor obstruc-tions such as: electrical wiring chases, unusually long computer system cables, or piping clusters.

All piping below the elevated floor must be located so that it offers the least resistance to air flow.

Careful planning of the piping layout under the raised floor is required to prevent the air flow from being blocked. When installing piping on the subfloor, it is recommended that the pipes be mounted in a horizontal plane rather than stacked one above the other. Whenever possible, the pipes should be run parallel to the air flow.

Always check specifications of the floor supplier before specifying the total number of perforated pan-els and grilles required to handle the air flow. The proper specifications for grilles and perforated pan-els should indicate the total free area required for air delivery rather than the number of panels and grilles. (See Table 7 below for recommended free area required for each model.) This table indicates the recommended free area based on having the supply air grilles and perforated panels sized to han-dle approximately 75% of the total cubic feet per minute (CFM) of the units at a velocity of 550 to 600 ft./min. (2.8 - 3.1 m/s). The remaining 25 percent of the air flow in the raised floor passes through cable cutouts, cracks between the panels and other leakage areas.

Upflow models can be configured in several different ways with front return, rear return, or bottom return and top front supply or top rear supply. For in-room applications with no ductwork, and optional plenum with grill, proper clearance must be maintained on the return air side of the unit.

For a front return, this means several feet in front of the unit. For a bottom return, at least 6-8 inches of unrestricted under-floor height is needed.

2.6.3 Ducted Application Installation

Duct flanges are supplied on the blower outlets. Follow the SMACNA-Duct Construction Standard for single-, dual-, or triple-blower systems. Do not run ductwork off the perimeter flange on the top of the unit. This flange is for positioning and attaching the optional air discharge plenum with grill. Attach-ing a duct to this flange may reduce airflow to inadequate levels.

Figure 13 Ducting configurations

2.6.4 Plenum Installation

When installing the plenum to the top of system, secure the plenum to the unit flange using sheet metal screws.

2.6.5 Filter Box Installation (Upflow Rear Return)

When installing the filter box to the back of the unit, secure the box to the unit using self tapping sheet metal screws. Seal around all edges with a silicone sealant to prevent air leakage.

NOTE

Air distribution plenums are available as Top Return/Downflow, Top Discharge/Upflow, and Front Discharge (with or without grilles)/Upflow. These plenums are shipped separate and unassembled. Refer to assembly manual included with plenums.

Straight section of duct off unit to be 1.5 to 2.5 times the longest blower dimension

Typical ducting shown; may run to either side

* Follow standard practices on all duct work

3.0 CHILLED WATER MODELS

3.1 Piping Considerations

Manual shut-off valves should be installed at the supply and return lines to each unit. This provides for routine service and emergency isolation of the unit.

The lowest water temperature to be supplied by the chiller will determine whether insulation is needed to prevent condensation on the supply and return lines. To prevent water damage to flooring and subflooring, install a water detection system, such as a Liqui-tect or floor drains with wet traps.
