OVERVIEW

The installation process consists of the following steps:

1. Determine Location

• Foundation Requirements

• Clearance Requirements

2. Rig Chiller to Final Location

3. Install Isolators

• Locate and place Isolator Pads, or
• Install optional Spring Isolators
4. Level Chiller
5. Make Connections
• Piping
• Wiring
6. Apply Insulation
The rigging, operating weights, and
overall dimensions are provided in Sec-
tion 5 - Dimensions, Nozzle Arrangements
And Weights to help you determine the
clearances required for rigging. Add 6"
(15 cm) to overall height for optional
skidded unit.
DETERMINE LOCATION
Sufficient clearance to facilitate normal
service and maintenance work must be
provided around and above the unit and
particularly space provided at either end to
permit cleaning or replacement of evapo-
rator and condenser tubes – see Clear-
ance. A doorway or other sufficiently large
opening properly located may be used.
The chiller should be located in an indoor
location where temperatures range from
40°F to 110°F (4.4°C to 43.3°C).
Foundation Requirements
A level floor, mounting pad or foundation must be pro-
vided by others, capable of supporting the operating
weight of the unit.

Clearance Requirements
Clearances should be adhered to as follows:
* 8' (2.4m): 2508 Shell Codes

RIG UNIT TO FINAL LOCATION

Rig the unit to its final location on the floor or mount-
ing pad, lift the unit (or shell assembly) by means of an
overhead lift and lower the unit to its mounting posi-
tion. (If optional shipping skids are used, remove them
before lowering the chiller to its mounting position.)
If evaporator is to be field insulated, the insulation can
be applied to the evaporator while the unit is in the lift
position to gain more access below the shell, if neces-
sary. Be sure unit is properly supported. (Refer to In-
sulation in this section and Figure 21 on page 32 for
further information.)
INSTALL ISOLATORS
Neoprene isolator pads are furnished standard and
typically satisfy the installation engineer's vibration
isolation requirements when the chiller foundation
is not likely to transmit to occupied spaces. Optional
spring isolators can be selected when the location of
the equipment room floor dictates more stringent limits
on vibration input.

Neoprene Isolator Pads

Locate And Place Isolator Pads
The isolator pad mounts are to be located and placed
rubber-side down as shown in Figure 21 on page 32.
After the isolator pads have been placed into position
on the floor, lower the chiller onto the pads. When the
unit is in place, remove the rigging equipment and
check that the unit is level.
