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.

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:
.   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.

If the low side refrigerant pressure drops to 5 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.

The Phoenix 200 HT is equipped with a pleated fabric air 
filter that must be checked regularly. The standard filter 
is a MERV- high efficiency filter. Operating the unit with 
a dirty filter will reduce the dehumidifier’s capacity and 
efficiency and may cause the compressor to cycle off and 
on unnecessarily on the defrost control.
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.

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.
.   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 bio-fungicide that is approved for use with copper, 
aluminum and polyethylene. To flush:
.   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.
