Operation

2.1 Transporting the Phoenix
The Phoenix 250 MAX 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.

2.2 Location
Note the following precautions when locating the Phoenix 250 MAX:

• 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 250 MAX as a bench or table.
• It must always be used in the upright position.
• The air inlet on top & the side outlet must be at least 1 foot from walls and other obstructions to air flow.
• If the humid area is very large, dehumidification can be improved by adding an outlet duct to circulate air to stagnant areas (see Sec. 2.5).

2.3 Electrical Requirements
The Phoenix 250 MAX plugs into a common grounded outlet on a 15 Amp circuit. It draws 8.2 Amps at 80°F, 60% RH. Amp draw increases with increasing temperature and\or humidity. 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 250 MAX 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 250 MAX outlet. Lay-flat plastic ducting is available from Therma-Stor.
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 250 MAX by snapping the collar over the four screws at the blower outlet.

2.6 Power Switch
The power switch (right of hour meter) lights up when the unit is turned on. The unit will continue to run in all conditions until the switch is turned off; there is no dehumidistat.

2.7 Pump Purge Switch
This switch (left of hour meter) minimizes the water left in the condensate pump reservoir for moving or storage.
Pressing and holding the pump purge switch will cause the condensate pump to run. Hold the switch in until the flow from the condensate hose stops.
2.8 Hour Meter
The digital hour meter measures the cumulative time that the unit is turned on to tenths of an hour. It stores its total when the unit is unplugged; the previous total will be displayed when the unit is next turned on. It resets to zero after 99,999.9 hours of operation.
2.9 Defrost Control Adjustment
If the unit is going to run for more than 2 hours in an area below 50°F, the defrost timer can be adjusted to improve performance. When the Phoenix 250 MAX is used in a cool area, or the dewpoint is below 50°, frost will form on the cooling coil as it dehumidifies. When enough frost forms, the defrost thermostat will initiate the timed defrost cycle. The cycle periodically turns off the compressor while allowing the blower to run. The frost is melted by the air that the blower draws through the cooling coil.

Each lever on the front face of the timer represents 15 minutes (factory set is 1 in and 1 out). Change the control having 2 levers pushed in and 1 lever pushed out around the face of the timer. Leave 4 consecutive levers pushed out on the face of the timer (1 hour off period)> This ensures any ice build-up on the evaporator will melt away.
This setting helps only in conditions under 50°F, and is not recommended in warmer temperatures.
DRYING TIP: Air’s ability to absorb moisture from wet surroundings and the Phoenix 250 MAX’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.

2.10 Low Pressure Control
If the low side refrigerant pressure drops to 35 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) 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.

Maintenance

3.1 Air Filter
The Phoenix 250 MAX is equipped with a pleated fabric 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 cause the compressor to cycle off and on unnecessarily on the defrost control.

IMPORTANT

3.2 Storage and Freeze Protection
There are two issues to consider when the Phoenix 250 MAX 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:
   a. Run the hose to a drain.
   b. Plug in the unit but do not turn it on.
   c. Remove the air filter. Slowly pour a quart of the antimicrobial through the heat exchanger
   d. Hold in the pump purge switch to reduce the water level in the reservoir.
   e. Flush with water.

4. If the unit will be exposed to freezing temperatures, after purging, pull back the filter and pour 1 cup (8oz) of a 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.

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

Service

CAUTION: Servicing the Phoenix 250 MAX 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: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified person in order to avoid a hazard.

4.1 Warranty
A warranty certificate has been enclosed with this unit; read it before any repair is initiated. If a warranty repair is required, call the factory first at 1-800-533-7533 for warranty claim authorization and technical assistance.
4.2 Technical Description
The Phoenix 250 MAX 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 (see Fig. 2).

Hot, high pressure refrigerant gas is routed from the compressor to the condenser coil (see Figure 2). 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.

4.4 Refrigerant Charging
If the refrigerant charge is lost due to service or a leak, a new charge must be accurately weighed in. If any of the old charge is left in the system, it must be removed before weighing in the new charge. Refer to the unit nameplate for the correct charge weight and refrigerant type.

4.5 Air Mover Replacement
The impeller has a PSC motor and internal thermal overload protection. If defective, the complete assembly must be replaced.

1. Unplug the power cord.
2. Remove the front cover.
3. Remove five screws attaching impeller inlet ring.
4. Remove the four screws mounting impeller to underside of base plate.
5. Disconnect the blower leads
6. Reassembling with the new impeller in reverse order using the above procedure in reverse.

4.6 Condensate Pump Replacement
The internal condensate pump removes water that collects in the reservoir.

To replace the condensate pump:

1. Unplug the unit
2. Remove the rear skidplate
3. Unplug the pump wires from the wire harness
4. Remove the condensate hose and the screw attaching the pump bracket to the base
5. Replace the pump, hose, wiring, bolts, and cover in the reverse order

4.7 Compressor/Capacitor Replacement
This compressor is equipped with a two terminal external overload, run capacitor, but no start capacitor.
4.8 Defrost Thermostat and Timer
The defrost thermostat is attached to the refrigerant suction tube between the accumulator and compressor. If the low side refrigerant temperature drops due to excessive frost formation on the evaporator coil, the thermostat opens. The compressor is then cycled off and on by the defrost timer.
The blower 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 increase, the evaporator temperature will rise and the thermostat will close to end the defrost cycle.

4.9 Gravity Drain Option
If the condensate pump fails and cannot be replaced immediately, the Phoenix 250 MAX can be used by draining by gravity.

1. Unplug the unit and remove the front cover.
2. Push the plastic plug on the right side out from inside the unit.
3. Locate the heavy vinyl hose that connects the drain pan to the condensate pump. Pull the end out of the pump.
4. Remove tie wrap holding drain tube to suction line.
5. Push that end of the vinyl hose through the hole in the right side.
6. Connect a garden hose and run it to a drain. Keep the hose as flat to the floor as possible to avoid air pockets that would hinder draining. Placing the unit on something above the floor will also improve draining.

4.10 Relay
The contacts of the single pole, single throw relay complete the power circuit to the compressor. The contacts are closed when power is provided to the relay coil via the control circuit. The control circuit includes the power switch, low pressure control, defrost thermostat and timer.
