Note: Charging should be done with a dial-a-charge or weighed in with a scale.

9.Once certain of a good evacuation and leak free joints, back-seat the valves (counter-clockwise) to open and allow factory charge to fill lines and indoor unit.

10.Charge to proper weight, charge based on feet of interconnect (table on next page)

11.Refer to Field Charging Charts to “fine tune” the refrigerant charge to meet

your conditions.

The units are delivered pre-charged 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 interconnect piping. Unit service valves are solid brass, for sweat connections.

IMPORTANT: All systems require field charge adjustments. Refer to the "Refrig- erant Charge Tables" for proper weight charge and to the supplied “Field Charging Charts" for proper system pressures and temperature at different outdoor condi- tions. Superheat should be used for final system charge in cooling mode. Subcool should be used for final system charge in heating mode.

PIPING CONNECTIONS

Pressure test all field installed piping and the indoor air handler with nitrogen. Using a suitable vacuum pump, evacuate the tubing and indoor unit to 500 microns or less, with service values remaining front seated (closed).

Before releasing the refrigerant from the condenser, be sure the manifold gauge set is closed so as not to lose vacuum when shutting down the pump.

Release refrigerant from the condensing unit by back seating the service value. Al- len wrenches are used to open the valve. Replace valve caps. Be careful to not back seat the valves past the snap fanges that hold the valve core in place.
