Forklifting Procedure
Important:
Step 1 through Step 4 must be followed to lift unit using a
forklift.
Steps to be taken when forklift is used:
1. Remove the stretch wrap from the unit as described
previously, leaving the unit mounted to the skid.
2. Remove the bolts that secure the unit to the shipping
skid.
3. Using a forklift, raise the unit enough to slightly clear
the skid, making sure the unit is level when lifting.
4. If the unit is level, lift the unit off of the skid and place
in the installation location.
Rigging Procedure
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping
and possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. Test lift unit approximately 24
inches to verify proper center of gravity lift point. To
avoid dropping of unit, reposition lifting point if unit is
not level.
Note: Do not lift unit from above unless spreader bars are
used.
Each module should be lifted using lift straps threaded
through the steel base cutouts and a spreader bar.
Note: If no, or improperly sized, spreader bar is used,
damage to the unit may occur.
NOTICE
Equipment Damage!
To prevent damage, position the spreader bar and
straps so that they do not contact unit piping or control
panel.

Access Restrictions

All CICD units are designed to pass through a standard 36
inch doorway. See outline drawings for other important
dimensions.

Compressor Mounting

All compressors are rigidly bolted with compressor
isolation mounts to the same compressor mounting frame
(rails). No additional isolation or leveling is required.
Inspect prior to start up to ensure bolts are present and
tight, and that no shipping damage has occurred.

Direct Mounting

The unit can be installed directly on an isolated, rigid
mounting surface as long as the surface is level and will
support the weight of the unit. A mounting hole is provided
at each of the unit mounting locations. See
p. 21 for more details. Provide a means of securely
anchoring the unit to the mounting surface. Level the unit
carefully.

Unit Leveling

Before tightening the mounting bolts, level the unit. Check
unit level front-to-back (depth) by using a level, or by
placing a level on the top surface of the unit frame. Unit
should be level within 1/8 inch front-to-back (depth). Place
the level on the unit frame and check side to side level.
Adjust to within 1/8 inch of level side-to-side. Use shims as
required to properly level the unit.
The serial number information is also on record at the
factory.

Typical Water Piping

All building water piping must be flushed prior to making
final connections to the chiller. To reduce heat loss and
prevent condensation, insulation should be applied.
Expansion tanks are also usually required so that chilled
water volume changes can be accommodated.

Avoidance of Short Water Loops

Adequate water volume is an important system design
parameter because it provides for stable chilled water
temperature control and helps limit unacceptable short
cycling of chiller compressors.
The chiller's temperature control sensor is located in the
supply (outlet) water connection or pipe. This location
allows the building to act as a buffer to slow the rate of
change of the system water temperature. If there is not
sufficient water volume in the system to provide an
adequate buffer, temperature control can suffer, resulting
in erratic system operation and excessive compressor
cycling.
