2.3 Electrical Requirements
The Phoenix 270HTx plugs into a common grounded outlet
on a 15 Amp circuit. It draws 8.9 Amps at 80°F, 60% RH.
If used in a wet area, a ground fault interrupter (GFI) is
required.
If an extension cord is required, it must have a minimum of
14 gauge conductors if 25 feet long or less and 12 gauge
conductors if greater than 25 feet long.
2.4 Condensate Removal
The Phoenix 270HTx is equipped with an internal
condensate pump to remove the water that is condensed
during dehumidification. This allows the condensate to be
pumped 30’ with the attached hose. If the condensate
must be pumped more than 20 feet above the unit, a
second pump must be added to relay the condensate. If
the pump fails and the unit must be used before it can be
replaced, the condensate can be drained by gravity (see
Sec. 4.9).
2.5 Ducting
A detachable rectangular exhaust collar is supplied that
will allow 10” round lay-flat duct to be attached to the
Phoenix 270HTx outlet.
To attach ducting to a collar, put the plastic duct end
through the collar center and roll the duct end outward
so that it overlaps the outside of the collar. The duct and
collar may then be quickly attached to the Phoenix 270HTx
by snapping the collar over the four screws at the blower
outlet.
2.6 Power Button
Press the POWER button to turn the dehumidifier on or off.
When starting the dehumidifier the display will show the
accumulated hours. Press the POWER button again to turn
the dehumidifier off. The display will also power off.
2.7 Pump Purge Button
During normal operation the pump automatically cycles
every four minutes. Press the PURGE button to remove
condensate manually from the reservoir. There are several
ways to manually remove water from the reservoir:
1. Press the PURGE button once and the pump will run
for 20 seconds
2. Press and hold the PURGE button and the pump will
run for up to 30 seconds
3. Press the PURGE button while the dehumidifier is
powered off and the pump will run for 30 seconds.
Always manually purge the water reservoir before transport
or storage. Turn off the power and allow the plugged in
dehumidifier to rest 15 minutes before the final purge.
2.8 Hour Meter
The digital hour meter displays the cumulative and job time
the dehumidifier has been turned on to the tenth of an
hour. The total and job hours measured are stored when
the unit is unplugged. The previous total will be displayed
the next time the unit is turned on. The job hours can be
reset by pressing and holding the HOURS button for 5
seconds when the unit is operating.
2.9 HOURS Button
Press the HOURS button when the dehumidifier cannot
be plugged in and the hour meter needs to be read.
The digital hour meter will briefly display the last saved
cumulative time for 10 seconds.
2.10 DEFROST Light
The DEFROST light turns on when the unit is in defrost
mode indicating when the compressor is off.
DRYING TIP: Air’s ability to absorb moisture from wet
surroundings and the Phoenix 270HTx’s ability to remove
moisture from that air is greatly improved at higher
temperatures. We recommend that the area to be dried be
heated to over 70°F if possible. Less drying time will be
required and efficiency will improve.
2.11 Low Pressure Protection
If the low side refrigerant drops into a low pressure situa-
tion that may harm the compressor, the solid state con-
trols will sense the refrigerant conditions and shut off the
compressor until the system automatically resets itself.
The solid state control monitors and compares the ambi-
ent temperature and refrigerant conditions to ensure the
system is protecting compressor at all times. The control
protects the compressor from damage by monitoring
cycles, pressures, and system performance.
2.12 Defrost Cycle
If the low side refrigerant temperature drops below the
defrost set point, due to excessive frost formation on
the evaporator coil, the thermistor activates the solid
state control and the defrost light. The control cycles
the compressor “off” and “on” by monitoring thermistor
temperature. The air mover will continue to run, causing
air to flow through the evaporator coil. The air will melt the
ice that formed on the evaprator.
When the air temperature and/or humidity increases, the
evaporator temperature will rise and the thermistor will end
the defrost cycle restarting the compressor.
