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. 2.8 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. 2.4 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). 2.9 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. 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. 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. 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 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. 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. When the air temperature and/or humidity increases, the evaporator temperature will rise and the thermistor will end the defrost cycle restarting the compressor. 3 www.UsePhoenix.com • sales@UsePhoenix.com Toll-Free 1-800-533-7533

If the evaporator temperature does not reach the desired temperature, the compressor will start after 15 minutes. The system will start a timed defrost cycle. The timed defrost cycle ensures the unit will continue to remove water from the air in cool ambient conditions. 4 Service CAUTION: Servicing the Phoenix 270HTx 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. 2.13 Automatic Bypass Control The Phoenix 270HTX senses the ambient conditions during normal operations.

The bypass door automatically moves into the correct position maximizing performance and efficiency depending on inlet conditions. 4.1 Technical Description The Phoenix 270HTx 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). 3 Maintenance 3.1 Air Filter The Phoenix 270HTx 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: 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. 3.2 Storage There are two issues to consider when the Phoenix 270HTx is stored between uses. 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. 1.

Use the pump purge switch (see Sec. 2.7 & Fig. 4) to Figure 2: Refrigeration system 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. reduce the water level in the reservoir. 2. Stretch the hose flat to drain it completely. Raise one end above your head and spool to drain water out of the other end. 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: 1. Run the hose to a drain. 2. Plug in the unit but do not turn it on. 3. Remove the air filter. Slowly pour a quart of the chemical through the heat exchanger 4.

Hold in the pump purge switch to reduce the water The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching level in the reservoir. 5. Flush with water. 4 www.UsePhoenix.com • sales@UsePhoenix.com Toll-Free 1-800-533-7533
