Product Usage Instructions

Before using the Phoenix R250 dehumidifier, read the operation and maintenance instructions carefully. Proper adherence to these instructions is essential to obtain maximum benefit from your dehumidifier.

Safety Certifications

The Phoenix R250 conforms to unified standard UL 603352-40.

Transporting

The Phoenix R250 must always be upright when transported by vehicle. It may be tipped onto 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.

Location

Place the dehumidifier inside the structure and make sure all windows and doors are closed to the outside. Seal off the affected wet areas from unaffected areas to decrease drying times.

Electrical Requirements

The Phoenix R250 requires a power source of 8.3 amps, 120 VAC, and Grounded.

Condensate Removal

Place the condensate hose into a drain or a large water-tight container.

Ducting

The Phoenix R250 has multiple ducting options.

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 the thermistor temperature measurement. The air mover 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 increases, the evaporator temperature will rise and the thermistor will end the defrost cycle at the defrost set point.

Operation

Place dehumidifier 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.

Transporting

The Phoenix R250 must always be upright when transported by vehicle. It may be tipped onto 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.

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 an upright position.

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.
Condensate Removal
The Phoenix R250 is equipped with an internal condensate pump to remove the water that is condensed during dehumidification. 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 the reservoir. If the condensate level rises in the reservoir to a critical level a back-up float 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.
Ducting

A wire duct collar is supplied to allow 10” lay-flat duct to be attached to the Phoenix R250 outlet. Lay-flat 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” flex duct (see accessories in section 6). Attach the flex du

ct to the top cover by hooking the spiral wire under the four tabs. Tape the duct to the top cover for a complete seal.
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 the thermistor temperature measurement. The air mover 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 increases, the evaporator temperature will rise and the thermistor will end the defrost cycle at the defrost set point.
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.
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 dehumidifier 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 dehumidifier to rest 15 minutes before the final purge.
Hour Meter
The digital hour meter displays the amount of time the dehumidifier 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.
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.
Defrost Light
The DEFROST light turns on when the unit is in defrost cycle and indicates when the compressor is off.
Bypass Control
Below 90°F – When the Phoenix R250 is used in normal dehumidifier operating temperatures (below Bypass Cover 90°F), the bypass cover must close the bypass openings, figure 4. This maximizes performance by increasing the amount of air that is dehumidified across Figure 4: Below 90° (Normal) the evaporator. This temperature range is Bypass Cover often found during the first 24 hours of a drying job. Above 90°F – When the Phoenix R250 is used in high temperature conditions above 90°F, reposition Figure 5: At or above 90°the bypass cover to open the bypass  holes, figure 5. Thisimproves dehumidifier efficiency by increasing the amount of airflow Bypass openings located under filter over the condenser and lowering the refrigerant pressure. Simultaneously, this slows the airflow across the evaporator allowing the air temperature to be lowered to the dew
point and increases dehumidifier capacity. These higher temperatures are often found after the first 24 hours.

Maintenance

Air Filter
The Phoenix R250 is equipped with a pleated media air filter that must be checked regularly. The standard filter is a MERV-11 high-efficiency filter. Operating the unit with a dirty filter will reduce the dehumidifier’s capacity and efficiency and may force the unit into defrost causing the compressor to cycle “off” and “on” unnecessarily. The filter can generally be vacuumed cleaned several times before needing replacement. Replacement filters can be ordered from the manufacturer or purchased locally if available.

IMPORTANT: DO NOT operate the unit without the filter
or with a less effective filter as the heat exchanger and coils inside the unit could become clogged and require disassembly to clean.
Storage and Freeze Protection
There are two issues to consider when the Phoenix R250 is stored between uses and both pertain to water trapped in the unit.  The first is biological growth and the second is damage caused by freezing. The effects 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 button to reduce the water level in the reservoir.

2. Stretch the hose flat to drain it completely. Raise one end above your head and spool hose while draining water out the other end.

3. To reduce biological growth flush the unit with a
   bio-fungicide that is approved for use with copper, aluminum and polyethylene. To flush:

4. Run the hose to a drain.

5. Plug in the unit but do not turn it on.

6. Remove the air filter. Slowly pour a quart of the antimicrobial through the heat exchanger.

7. Hold in the pump purge switch to reduce the water level in the reservoir.

8. Flush with water.

9. If the unit will be exposed to freezing temperatures, after purging, pull back the filter and pour 1 cup (8oz) of propylene glycol-based anti-freeze through the heat exchanger. It will flow down into the pump reservoir. Do NOT purge the solution out of the unit.

10. Dirty filters should be changed prior to long-term storage to prevent biological growth on the filter.

Service

WARNING: Servicing the Phoenix R250 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.
CAUTION: Do not operate unit without the front housing in place.

Technical Description
The Phoenix R250 uses a refrigeration system similar to an air conditioner’s to remove heat and moisture from incoming air and to add heat to the air that is discharged.
Hot, high-pressure refrigerant gas is routed from the compressor to the condenser coil. The refrigerant is cooled and condensed by giving up its heat to the air that is about to be discharged from the unit. The refrigerant liquid then passes through a filter/drier and capillary tubing which cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates. The evaporator operates in a flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain constant pressure and temperature across the entire coil, from inlet to outlet. The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature to repeat the process.
