the evaporator more quickly and efficiently. See Figure 3 below for correct grain control magnet position and defrost timer for operating in temperatures below 50°F.

3 Maintenance
3.1 Air Filter
The Phoenix 200 HT is equipped with a pleated fabric air filter that must be checked regularly. The standard filter is a
The filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be ordered from the factory or purchased locally if available.
DRYING TIP: Air’s ability to absorb moisture from wet surroundings and the Phoenix 200 HTs ability to remove moisture from that air is greatly improved at higher temperatures. The defrost cycle is automatic and designed for optimum performance above 50°F. If the unit is used in an area that is below 50°F for more than 2 hours, adjustment of the defrost timer is recommended.
To adjust the defrost timer:
1.Unplug the unit.
2.Remove the top panel and the front cover (6 screws).
3.The timer is fastened to the base at the front of the unit. Every third peg around the dial is pushed out from the dial center except one section with 4 pegs out in a row. The grain control (8 holes at the intake of the unit below the filter) should be open. Refer to Figures 2 and 3.
4.To improve performance below 50°F, the compressor “off” time must be increased to allow the frost to completely melt. To do this, push the pegs out from the dial center so that the pegs alternate with 2 toward the center, then 2 out from the center, all the way around the dial except for the section now with 6 pegs out in a row. Refer to Figure 3.
5.Replace the cover and top panel.
2.9 Low Pressure Control
If the low side refrigerant pressure drops to 15 PSIG, the low pressure control opens and shuts off the compressor and blower. It is an automatically reset control. Its primary function is to prevent damage to the compressor if a leak develops in the refrigeration system. It may also open if the unit is A) used in a cool area (below 50°F) and the defrost timer is not adjusted or B) stored where it is below 40°F and then started. Under these conditions, the unit will restart within several minutes; it may cycle several times until the unit warms up.
WARNING: DO NOT operate the unit without the filter or with a less effective filter as the heat exchange coils inside the unit could become clogged and require disassembly to clean.
3.2 Storage
There are two issues to consider when the Phoenix
200 HT is stored between uses and both pertain to the water trapped in the unit: damage caused by freezing or biological growth.
The effect of the trapped water can be greatly reduced if precautions are taken to remove as much as possible before storage.
1.Use the pump purge switch to reduce the water level in the reservoir.
2.Stretch the hose flat to drain it completely.
If the unit will not be exposed to freezing temperatures, an alternative to reduce biological growth is to flush the unit with a
1.Run the hose to a drain.
2.Remove the air filter. Slowly pour a quart of the chemical through the top grille so that it drains into the plastic slots.
4.Hold in the pump purge switch to reduce the water level in the reservoir.
4 Service
WARNING: Servicing the Phoenix 200 HT with its high pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit.
Do not operate unit without the front panel in place.
