4. At least 15” clear space is required above the unit for service.
5. At least 6” is required on both sides of the cabinet (for servicing the control panel and door opening).
CONNECTION TO THE REMOTE UNIT
The specified diameters (see chart on page 6) for the copper tubing used to connect the remote
condensing unit to the cabinet are adequate for a separation of up to 60 feet. For greater
distances, contact the factory for instructions.
NOTES:
1. The insulation used on the piping must be of high quality and must have closed cells.
2. Refer to page 5 for connection drawings.
3. Quick disconnects MUST be mounted where shown.
4. Note the information regarding the installation of siphons (traps) when the cabinet and the
remote condensing unit are at different levels. They are NOT
needed when the condensing unit is
at a lower level than the cabinet.
CONDENSATE DRAINAGE CONNECTION
It is important that the condensate from the evaporator is properly drained. The drain line from the
evaporator exits from the rear of the cabinet. It must be connected in conformance with local
regulations.
VERIFYING CORRECT INSTALLATION
a. Check that there are no refrigerant leaks.
b. Check that the refrigerant piping is insulated fully and correctly.
c. Check that siphons (traps) have been installed.
d. Check that the required quick disconnects have been installed.
e. Check all electrical connections and that the power supply is of proper voltage (208 VAC +/- 5%,
1ph., 60 Hz.).
f. If the condensing unit is water cooled, check the connection to the water supply and the setting of
the pressure valve.
g. Check the provision for drainage of condensate water.
h. If a unit has been transported in a non-vertical position (e.g. on its back) or if it has been overturned
during installation, WAIT AT LEAST TWELVE HOURS BEFORE TURNING IT ON.
i. If the condensing unit has been outside in cold temperatures, turn on the power to it for at least
twelve hours before installation.
j. Make sure that the refrigerant is Type 404A and adjust the expansion valve if necessary.
k. Make sure that the fans of an air cooled condensing unit blow the air "UP".
l. Make sure that the fans inside the cabinet rotate clockwise.
m. Make sure that the cabinet has been leveled.
