Evaporator coil frosted continuously, low dehumidifying capacity.

1.Defrost thermostat loose or defective.

2.Defrost timer incorrectly set or defective.

3.Low refrigerant charge.

4.Dirty air filter or air flow restricted.

Compressor runs with power switch OFF.

1.Defective relay.

2.Defective power switch.

4.3 Blower Replacement

The motorized impeller has a PSC motor and internal thermal overload protection. If defective, the complete assembly must be replaced.

1.Unplug the power cord.

2.Remove the top panel and cabinet front (6 screws).

3.Disconnect the impeller leads.

4.Remove four screws holding the impeller to the impeller brackets.

5.Remove four screws holding the impeller brackets to the condenser shroud.

6.Remove impeller and impeller brackets. Use care to avoid hooking wiring, tubing or electrical components.

7.Reassemble with the new impeller in the above procedure reversed.

4.4 Defrost Thermostat and Timer

The defrost thermostat is attached to the refrigerant suction tube between the accumulator and compressor. If the low side refrigerant temperature drops due to excessive frost formation on the evaporator coil, the thermostat opens. The compressor is then cycled off and on by the defrost timer. The blower will continue to run, causing air to flow through the evaporator coil and melt the ice when the compressor is off. When the air temperature and/or humidity increase, the evaporator temperature will rise and the thermostat will close to end the defrost cycle. To improve performance in low temperatures refer to Section 3 for defrost timer adjustment.

4.5 Condensate Pump

Condensate is automatically pumped when the water level in the pump’s reservoir rises to close the float switch or if the pump purge switch is held in.

To replace the condensate pump:

1.Remove the metal strap holding the pump by loosening the 2 screws holding it in place.

2.Disconnect the leads.

3.Installation is the reverse of above, but check that the plastic inlet and outlet hoses do not rub against copper refrigerant tubes.

4.6 Gravity Drain Option

If the condensate pump fails and cannot be replaced immediately, the Phoenix 200 HT can be used by draining by gravity.

1.Unplug the unit and remove the front cover.

2.Push the plastic plug on the left side 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 left 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.
