WARNING
It is illegal to discharge refrigerant into the atmosphere. Use proper re- claiming methods & equipment when installing or servicing this unit.
The units are delivered precharged with refrigerant for the condenser coil and the evaporator. Charging of the field 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 field 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 final 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.
Note: The following air handlers are equivelent in electrical specifications and system combinations.
WLH09 = UNH09
WLH12 = WLH12
WLH24 = UNH24
WLC30 = UNC36
WLC36 = UNC36
