Therma-Stor Products Group Phoenix 200 HT 사용자 설명서

6

Evaporator coil frosted continuously, low dehumidifying 
capacity.
.   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.
.   Defective relay.
2.   Defective power switch.

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

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.

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:
.   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.

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