The units are delivered precharged
with refrigerant for the condenser coil
and the evaporator. Charging of the eld
installed piping is required. Refer to the
refrigerant charge table for the proper
amount to be added for the applications
interconect piping. Unit service valves are
solid brass, for sweat connections.
IMPORTANT: All systems require
eld charge adjustments. Refer to the
"Refrigerant Charge Tables" for proper
weight charge and to the supplied
"Operational Charts" for proper system
pressures and temperature at different
outdoor conditions. Superheat should
be used for nal system charge.
When charging and checking pres-
sures/temperatures on system supplied
with Low Ambient Option, the fan cycle
switch should be jumped out of the circuit
temporarily to obtain accurate data.
