6.Use the “SET” + or – button to adjust the hour for the Program 1 stop time. Be sure to pay attention to the am/pm setting.

7.Press the “PROG” button again. The display will indicate “Program 1/stop” at the bottom, and now the minute dis- play will flash.

8.Use the “SET” + or – buttons to adjust to the desired minute setting.

9.Pressing the “PROG” button again to move onto “program 2/stop” and begin the process again if setting the other programs. Follow the same procedure for each program.

10.To end the program process simply leave the control alone (don’t push any buttons) for about 10 seconds. The unit will remember any changes and return to “home state”.

5.2J Programming Notes

To run the ventilation program, the damper mode must be in the “program” mode (“Pr”).

The timer can be operated manually without changing the program by adjusting the damper mode from “program” to either “on” or “off”.

To delete a program after it has been entered, adjust the program so the “START” and “STOP” times are identical.

Occupants should determine ventilation times and rates. Therma-Stor Products makes no firm recommendations concerning when to ventilate. Common ventilation schedules include constant ventilation, ventilation based on occupancy times, intermittent operation, and seasonal ventilation.

Remember the control must be on for the unit to be functioning - make sure the green power indicator “ON” is lit.

5.2K Stop Start

During summer in hot, humid climates operating in ventilation mode will increase the moisture load in the home. Consider reducing the amount or frequency of fresh air ventilation if indoor humidity continues to be high.

6 Maintenance

6.1 Standard Air Filter

The UA-135H is equipped with a pleated cloth air filter. This filter should be checked every three months. Operating the unit with a dirty filter will reduce dehumidifier 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 standard filter or with a less effective filter than the standard filter. The heat exchange coils inside the unit could become clogged and require disassembly to clean. Filter non-compliance invalidates the product warranty.

6.2 High Efficiency Air Filter

An optional high efficiency pleated microglass paper filter is available for the UA-135H. This filter is rated as 90%-95% efficient by the ASHRAE Dust Spot test method 52-76. The high efficiency pleated microglass paper filter should be used in conjunction with the standard filter, and placed directly behind the standard filter.

This filter is able to remove allergy-causing particles from the airstream. Check the high efficiency air filter every two years and replace if necessary. Be careful not to damage the media when handling the high efficiency pleated paper filter. Do not attempt to clean the high efficiency pleated paper fil- ter. It should be replaced when it becomes restrictive.

6.3 Optional Fresh Air Return

Check and clean the screen on the outdoor fresh air return seasonally. The screen may become plugged during the seasons when there are many particles in the outdoor air.

7 Service

CAUTION

CAUTION: Servicing the UA-135H 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.

7.1 Technical Description

The UA-135H uses a refrigeration system similar to an air conditioner's to remove heat and moisture from incoming air, and add heat to the air that is discharged. Hot, high-pressure refrigerant gas is routed from the compressor to the condens- er coil (See Figure 1). The refrigerant is cooled and con- densed by giving up its heat to the air that is about to be dis- charged from the unit. The refrigerant liquid then passes through a filter/drier and capillary tubing which causes 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 evapora- tor should maintain nearly constant pressure and tempera- ture across the entire coil, from inlet to outlet.
