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.

MOUNTING

TC Series unit coolers are supplied for hanging via sheet metal baseplate. (Mounting centres as per Figure 1 and Table 1). Ensure all
mounting holes are utilised and in general mount unit flush to cabinet ceiling. Remove all packaging prior to positioning.

CLEARANCES

This evaporator draws air through the fan and discharges from the coil side, thus adequate clearance should be made on the entering grill
of the fan to ensure even unrestricted air flow through the coil. This distance should be approx. equal to the height of the coil or more.

Ensure enough room is left below and at the ends of the unit for servicing.

DRAIN LINE

If the evaporator is mounted flush to ceiling and level, the drain connection at either end is suitable for positive drainage. If unit is pitched
on an angle ensure drainage point is from lower fitting. If units are suspended below the ceiling, the installer must provide adequate pitch
to the unit by adjusting the hangers.

Note: Check for adequate drainage by pouring water into the drain pan. Ensure that the drain pan has sufficient slope for proper drainage
(prevention of ice build-up/blockage in pan).

Tube should be run from the drain connection, sloping at least 300mm per meter. A trap located outside of the cabinet should be provided
to prevent warm air entering through the tubing. Connection should be made to proper drainage facilities that comply with local
regulations.
