WARNING: This equipment contains refrigerant under 
pressure. Accidental release of refrigerant under 
pressure can cause personal injury and or property 
damage. 

 

 

WARNING: The exposed surfaces of motors, refrigerant 
piping, and other fluid circuit components can be very 
hot and can cause burns if touched with unprotected 
hands. 

 

 

CAUTION: Disconnect and lock out incoming power 
before installing, servicing, or maintaining the 
equipment. Connecting power to the main terminal 
block energizes the entire electric circuitry of the unit. 
Shut off the electric power at the main disconnect 
before opening access panels for repair or 
maintenance. 

 

 

CAUTION: Wear eye protection when installing, 
maintaining, or repairing the equipment to protect 
against any sparks, debris, or fluid leaks. 

 

 

CAUTION: The equipment will exceed 70 dBA sound 
pressure at 1 meter distance and 1 meter elevation 
when operating. Wear ear protection as required for 
personal comfort when operating or working in close 
proximity to the chiller. 

 

 

CAUTION: Wear protective gloves when installing, 
maintaining, or repairing the equipment to protect 
against any sparks, debris, or fluid leaks. 

 

Pre-Installation 

Receiving Inspection 

When the equipment arrives, verify the information 
on the nameplate agrees with the order 
acknowledgement and shipping papers. Inspect the 
equipment for any visible damage and verify all 
items shown on the bill of lading are present. If 
damage is evident, document it on the delivery 
receipt by clearly marking any item with damage as 
“unit damage” and notify the carrier. In addition, 
notify our Customer Service Department for 
assistance with preparing and filing freight damage 
claims, including arranging for an estimate on repair 
costs; however, filing the shipping damage claim is 
the responsibility of the receiving party. Do not 
install damaged equipment without getting the 
equipment repaired. 
 
Shipping damage is the responsibility of the carrier. 
To protect against possible loss due to damage 
incurred during shipping and to expedite payment 
for damages, it is important to follow proper 
procedures and keep records. Photographs of 

damaged equipment are excellent documentation 
for your records. 
 
Start unpacking the equipment, inspect for 
concealed damage, and take photos of any damage 
found. Once received, equipment owners have the 
responsibility to provide reasonable evidence that 
the damage did not occur after delivery. Photos of 
the equipment damage while it is still partially 
packed will help in this regard. Refrigerant lines can 
be susceptible to damage in transit. Check for 
broken lines, oil leaks, damaged controls, or any 
other major component torn loose from its 
mounting point. 
 
Record any signs of concealed damage and file a 
shipping damage claim immediately with the 
shipping company. Most carriers require concealed 
damages be reported within 15 days of receipt of 
the equipment. In addition, notify our Customer 
Service Department for assistance with preparing 
and filing freight damage claims, including arranging 
for an estimate on repair costs; however, filing the 
shipping damage claim is the responsibility of the 
receiving party. 
 

Equipment Storage 

When storing the equipment, it is important to 
protect it from damage. Blow out any water from the 
chiller; cover it to keep dirt and debris from 
accumulating or getting in, and store in an indoor 
sheltered area that does not exceed 145°F. 
 

Installation - Chiller 

Foundation 

Install the chiller on a rigid, non-warping mounting 
pad, concrete foundation, or level floor suitable to 
support the full operating weight of the equipment. 
When installed the equipment must be level within 
¼ inch over its length and width.
