The Phoenix R250 LGR Dehumidifier

• Coated Coils – For longer life, protection against
corrosion in the harshest environments, and protection
against the loss of the heat transfer properties of the
coil.

• Capacity - The Phoenix R250 removes 135 pints per
day at AHAM, (80°F/60%RH).

• Energy Efciency - Draws only 8.3 amps and removes

6.0 pints/kWh.

• 310 CFM - Faster drying and superior static pressure
for ducting.

• Hi-Temp Operation - up to 110°F

• Heavy-Duty Condensate Pump.

• Compact Design - 20”x20”x33.5”.

• Telescoping Handle - A heavy-duty retractable handle

for ease of transport and reduces space for storage
and stacking.

• Recessed 12” Wheels - Allows greater maneuverability

on the job site and efcient storage. Rolls over

obstacles with ease.

• Pleated Media Air Filter - A 12”x12”x1” MERV-11 lter

is standard.

• Stacking/Nesting - Reduces space for ease of stacking
and storage.

• Patented ByPass™ Technology - Increased
performance over a wide temperature range.

to be a rugged, high-performance dehumidier. Phoenix is

leading the industry by introducing epoxy coated coils. This
new feature will extend the life of the coil, provide protection in
corrosive environments, and maintain the coil’s heat transfer
ability over the life of the coil.

We kept the outstanding handle used on the R200 along with

patented ByPass™ Technology, increased airow, multiple
ducting options, and a pleated media lter. And, with some

amazing Phoenix Engineering, the R250 removes the most
water of the Phoenix rotomolds at 135 pints per day (AHAM)
while drawing only 8.3 amps of electricity, making it one of the
smallest, lightest XL category LGRs on the market.

Read the operation and maintenance instructions
carefully before using this unit. Proper adherence to these

instructions is essential to obtain maximum benet from
your Phoenix R250 dehumidier.

• It is designed to be used INDOORS ONLY.

• If used in a wet area, plug it into a GROUND FAULT
INTERRUPTER.

• DO NOT use the Phoenix R250 as a bench or table.

• It must always be used in the upright position.

3 Operation

Place dehumidier inside structure,

place condensate hose into a drain, or a
large water tight container, and turn on.
To decrease drying times, make sure all
windows and doors are closed to the outside
and seal off the affected wet areas from
unaffected areas.

Optimum performance will be observed
between the temperatures of 70°F and
95°F.

3.1 Transporting

The Phoenix R250 must always be upright when transported
by vehicle. It may be tipped on to its handle and back for
loading and moving by hand.

If the unit is transported on its side, let it sit upright at least
30 minutes before use.

3.2 Location

Note the following precautions when locating the Phoenix
R250:

• It is designed to be used INDOORS ONLY.

• If used in a wet area, plug it into a GROUND FAULT

INTERRUPTER.

• DO NOT use the Phoenix R250 as a bench or table.

• It must always be used in the upright position.

3.3 Electrical Requirements

The Phoenix R250 plugs into a common grounded outlet on
a 15 amp circuit. It draws 8.3 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.

3.4 Condensate Removal

The Phoenix R250 is equipped with an internal condensate
pump to remove the water that is condensed during

dehumidication. This pump allows the condensate to be

pumped 20 feet above the unit with the attached hose. If the
condensate must be pumped more than 20 feet above the
unit, a relay pump must be added. The condensate pump

automatically purges for 20 seconds every eight minutes. Use
the PURGE button to empty reservoir. If the condensate level
rises in the reservoir to a critical level a back-up oat switch

will activate the pump-out for up to 1 minute. If the water in
the reservoir fails to be evacuated, the safety switch will turn
off the compressor.

3.5 Ducting

A wire duct collar is supplied to allow 10” lay-at duct to be
attached to the Phoenix R250 outlet. Lay-at plastic ducting

is available (see accessories in section 6). Attach ducting to
the wire duct collar by inserting the plastic duct end through
the collar center and rolling the duct end outward to overlap
the outside of the collar. The duct and collar may then be
quickly attached to the Phoenix R250 by snapping the collar
over the four plastic exhaust tabs.

If the R250 is located in the unaffected area, the intake can

be ducted with 12” ex duct (see accessories in section 6).
Attach the ex duct to the top cover by hooking the spiral

wire under the four tabs. Tape the duct to the top cover for a
complete seal.

state control and the defrost light. The control cycles the
compressor “off” and “on” by the thermistor temperature
measurement. The air mover will continue to run, causing air

to ow through the evaporator coil and melt the ice when the

compressor is off. When the air temperature and/or humidity
increases, the evaporator temperature will rise and the
thermistor will end the defrost cycle at the defrost set point.

3.7 POWER Button

Press the POWER button to turn the dehumidier “on” or
“off”. When starting the dehumidier the display will show

the accumulated hours. Press the POWER button again to

turn the dehumidier off. The display will also power off.

3.8 PURGE Button

During normal operation the pump automatically cycles

every eight minutes. Press the PURGE button to remove

condensate manually from the reservoir. There are three
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 dehumidier is

plugged in but 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

dehumidier to rest 15 minutes before the nal purge.

3.9 Hour Meter

The digital hour meter displays the amount of time the

dehumidier has been turned on to the tenth of an hour. The

hour meter continuously cycles between total machine hours
and job hours every 3 seconds. Hours are stored in memory
even when the unit is unplugged. The previous totals will be
displayed next time the unit is powered on.

3.6 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-

3.10 HOURS Button

Pressing the HOURS button displays the hour meter when the

unit is turned off but plugged into power. To reset job hours,

press and hold the HOURS button for 5 seconds when the

unit is operating.
