Therma-Stor Products Group 200 MAX Electrical Requirements, Condensate Removal, Ducting

•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 200 MAX plugs into a common grounded outlet on a 15 Amp circuit. It draws 7.4 Amps at 80°F,

60% RH. Amp draw increases with increasing temperature and\or humidity; e.g. 10.2 amps at 90°F, 85% 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.

2.4 Condensate Removal

The Phoenix 200 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 200 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 200 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. If the unit is going to run for more than 2 hours in an area below 50°F, the defrost timer should be adjusted to improve performance (see Sec. 2.9).

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

When the Phoenix 200 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.

DRYING TIP: Air’s ability to absorb moisture from wet surroundings and the Phoenix 200 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.

The defrost cycle is automatic and designed for optimum performance above 50°F. If the unit is used in an area that is below 50°F for more than 2 hours, adjustment of the defrost timer is recommended. To adjust the defrost timer:

1.Unplug the unit.

2.Remove the top panel and the front cover (6 screws).

3.The timer is fastened to the base at the front of the unit. Every fourth peg around the dial is pushed out from the dial center except one section with 5 pegs out in a row. See figure 1. Each fourth “out” peg represents 15 minutes of compressor “off” time during every hour that the unit is in the defrost cycle.

4.To improve performance below 50°F, the compressor “off” time must be increased to 30 minutes per hour to allow the frost to completely melt. To do this, push the pegs out from the dial center so that the pegs alternate with 2 toward the center, then 2 out from the center, all the way around the dial except for the section now with 6 pegs out in a row (see Fig. 1).

5.Replace the cover and top panel.

Change the timer pegs back to the original pattern for use above 50°F.

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.
