Therma-Stor Products Group R175 owner manual Maintenance

3.2 Electrical Requirements

The Phoenix R175 plugs into a common grounded outlet on a 15 amp circuit. It draws 6.1 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.

3.3 Condensate Removal

The Phoenix R175 is equipped with an internal condensate pump to remove the water that is condensed during dehumidification. This allows the condensate to be pumped 20 feet 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. The condensate pump automatically purges for 20 seconds every four minutes. Use the PURGE button to manually remove condensation.

3.4 Ducting

A wire duct collar is supplied to allow 10” lay-flat duct to be attached to the Phoenix R175 outlet. Lay-flat plastic ducting is available; see accessories table page 6. To attach ducting to the wire duct 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 R175 by snapping the collar over the four exhaust tabs.

3.6 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.

3.7 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.

3.8 Hour Meter

The digital hour meter displays the cumulative time the dehumidifier has been turned on to the tenth of an hour. The total hours measured is stored when the unit is unplugged. The previous total will be displayed the next time the unit is turned on.

3.5 Defrost Cycle

If the low side refrigerant temperature drops due to exces- sive frost formation on the evaporator coil and below the temperature set point, the thermistor activates the solid- state control and defrost light. The compressor is cycled 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 com- pressor 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 temperature set point.

3.9 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 display the last saved cumulative time for ten seconds.

3.10 DEFROST Light

The DEFROST light turns on when the unit is in defrost cycle and indicates when the compressor is off.

4 Maintenance

4.1 Air Filter

The Phoenix R175 is equipped with a pleated media air filter that must be checked regularly. The standard filter is a MERV-7 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. The filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be ordered from the manufacturer or purchased locally if available.
