Refrigerant Charging; Compressor/Capacitor Replacement; Gravity Drain Option; Relay - Jon-Don Ultimate 340 Owner's Manual

4. Remove the condensate hose and the one screw
attaching the pump bracket to the base
5. Replace the pump, hose, wiring, bolts, and cover in the
reverse order

4.7 Refrigerant Charging

If the refrigerant charge is lost due to service or a leak, a
new charge must be accurately weighed in. If any of the
old charge is left in the system, it must be removed before
weighing in the new charge. Refer to the unit nameplate for
the correct charge weight and refrigerant type.

4.8 Compressor/Capacitor Replacement

This compressor is equipped with a two terminal external
overload, run capacitor, but no start capacitor or relay (see
Fig. 3).

4.9 Gravity Drain Option

If the condensate pump fails and cannot be replaced
immediately, the Ultimate 340 can be used by draining by
gravity.
1. Unplug the unit and remove the front cover.
2. Push the plastic plug on the right side (see Fig. 4) out
from inside the unit.
3. Locate the heavy vinyl hose that connects the drain pan
to the condensate pump. Pull the end out of the pump.
4. Push that end of the vinyl hose through the hole in the
right side.
5. Connect a garden hose and run it to a drain. Keep the
hose as flat to the floor as possible to avoid air pockets
that would hinder draining. Placing the unit on something
above the floor will also improve draining.

4.10 Relay

The contacts of the single pole, single throw relay complete
the power circuit to the compressor. The contacts are closed
when power is provided to the relay coil via the control circuit.
The control circuit includes the power switch, low pressure
control, defrost thermostat and timer.
