A minimum clearance of 42 in (2067 mm) is required to
other electrically grounded parts. A minimum clearance of
48 in (1220 mm) is required between two units opposite
each other (front-to-front or back-to-back) or to other
electrically live parts. See Section 110.26 of National
Electrical Code (NEC).
Important:
In all cases, local codes will take precedence
over these recommendations.
Ventilation
Provisions must be made to remove heat generated by
unit operation from the equipment room. Ventilation must
be adequate to maintain an ambient temperature lower
than 125°F.
The condenser relief valve on these units must be vented
in accordance with
all local and national codes
.
Drainage
Locate the unit near a large capacity drain for condenser
drain-down during shutdown or repair.
Handling
CCAR and CGWR units are shipped stretch-wrapped and
bolted to a shipping skid (unless other than standard
shipping is selected).
The skidded unit can be moved by using a fork truck of
suitable capacity. Refer to
“Dimensions and Weights,”
p. 11
for unit weights.
When moving the unit, the lifting forks must be positioned
under the shipping skid as wide as possible where labeled.
Lift the unit and move it to the desired location.
Once the unit is at the installation location, remove the
stretch wrap. Inspect the unit for damage and report if
damage is found.
The optional unit isolators (if ordered) are secured to the
shipping skid or in the unit control panel. Other optional
“ship loose” items may be attached to the skid or shipped
separately depending on options selected.
Rigging/Lifting Procedure
If the CGWR/CCAR is not moved using a forklift and the
forklift pockets provided as part of the chiller's frame, then
the chiller should be lifted and moved by using the lifting
rails as outlined in
Step 1
through
Step 8
.
A set of lifting rails is shipped loose and attached to the unit
skid. Install the lifting rails and lift as shown below:
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.
