PATTON UNIT COOLERS
INSTALLATION, OPERATION &
MAINTENANCE MANUAL
TC SERIES
The installation and start-up of Unit Coolers should only be performed by qualified refrigeration engineers/mechanics. Electrical
connections must be performed by suitably qualified personnel. The equipment should be installed in accordance with all applicable codes,
ordinances and local by-laws. Units are designed for refrigeration and/or air-conditioning systems utilising only the specified refrigerant
fluids as per technical documentation.
INSPECTION
Inspect all equipment before unpacking for visible signs of damage or loss. Check order list against models received to ensure shipment is
correct and complete.
IMPORTANT: Remember, you, the consignee, must make any claim necessary against the transportation company. Shipping damage or
missing parts, when discovered at the outset, will prevent later unnecessary and costly delays.
If damage or loss during transport is evident, make claim to carrier, as this will be their responsibility, not the manufacturers. Should
carton be damaged, but damage to equipment is not obvious, a claim should be filed for "concealed damage" with the carrier.
IMPORTANT: The electrical characteristics of the unit should be checked at this time to make sure they correspond to those ordered and to
electrical power available at the job site. Save all shipping papers, tags and instruction sheets for reference by installer and owner.
LOCATION
Determine the best location for the unit cooler in the space to be refrigerated. The unit location in the cabinet should be selected to ensure
uniform air distribution throughout the entire space to be refrigerated. Be sure that the unit does not draw air in, or blow directly out
through an opened door and that the stored product does not obstruct the free circulation of air.
Leave sufficient space under the unit to allow service of the drain tray and to access other components.
Consideration should also be given to minimize the piping run length to the condensing unit and drain outlet.

- Page 3 I, O & M Manual Cont’d. TC Series PIPING Refrigerant line sizes are important and may not be the same size as the coil connections (depends on the length of run). If in doubt, consult “Recommended refrigerant line size” charts or equivalent software.
- Page 4 Note : Before performing maintenance make sure the power supply is isolated and/or rendered safe. Patton Unit Coolers, in general, are maintenance free. However conditions of application subject equipment to differing levels of contaminants and corrosive exposure, therefore it is the operating companies responsibility to evaluate the checking periods required and/or the actions needed to ensure correct operation.
