HOW TO OPERATE DEHUMIDIFIER

HOW DOES THE DEHUMIDIFIER WORK?
Moist, humid air is drawn over a cold refrigerated dehumidifying coil. Moisture in the air condenses on this coil and drains into a bucket (or through the bucket into a hose and drain).
Dry, clean air is drawn over the condenser where it is actually heated several degrees and discharged out the front grill into the room. (See Figure 4)

It is normal for the surrounding air to become slightly warmer as the dehumidifier operates.
This warming effect further reduces the relative humidity of the surrounding air.

LOCATION FOR THE DEHUMIDIFIER
Allow at least 12 inches of space on all sides of the unit for good air circulation. (See Figure 5)

  • The dehumidifier must be operated in an enclosed area to be most effective.
  • Close all doors, windows and other outside openings to the room.

Goldstar-DHR-3030-Dehumidifier-5

Place the dehumidifier in a location that does not restrict air flow into the rear coil or out the front grille.
The operation of dehumidifier in a basement will have little or no effect in drying an adjacent enclosed storage area, such as a closet, unless there is adequate circulation of air in and out of the area.

MICRO SWITCH
The micro switch assembly, which is located on the drain pan of inside unit, automatically shuts off the dehumidifier when the bucket is full (note, the Auto Shut Off lights, to indicate bucket must be emptied). The bucket replaces in its place, the unit again turns itself on.

AUTO DEFROST
When frost builds up on the cooling coils, the unit will automatically cycle off until the frost disappears. The fan continues to run.

NOTE : The unit is designed to be operated at temperatures above 65°F(18°C) in normal conditions. If the dehumidifier is operated in low temperature conditions frost can form in the evaporator coil and the unit will cycle ON/OFF repeatedly. In this case, please check your room temperature conditions and stop the unit.
NOTE : The low temperature operation feature in the DH50EL and DH65EL models will continuously cycle up to a temperature of 43°F(6°C).

HUMIDITY CONTROLLER

Mechanical Type
The humidity control can be set anywhere between Off and Max for normal operation.
If you need more dehumidification, turn the Humidity Control toward Max. If you need less dehumidification, turn the Humidity Control toward Off.
The relative humidity range is from 20% to 80%. (See Figure 6)
Turn the Humidity Control to Off to stop the unit manually.

Electronic Type
The humidity control can be set ‘on’ or 35%-70%
RH(Relative Humidity) for normal operation. (See Figure 7) If you need drier air, press the v. Humidity Control button. If you need moister air, press the A Humidity Control button.
Press the Power button to stop the unit manually.

Goldstar-DHR-3030-Dehumidifier-6

DRYER (DH30, DHR-3030, DHE-3031)
Dryer is used to prevent capillary blockage from moisture in the refrigerant system and H/E, condenser and evaporator. Also, dryer is used to remove corrosion of the components.
NOTE: When dryer is replaced, proper injection to capillary is needed. On opening the dryer, it should be welded instantly. The oxidization of dryer inside and all tubes inside after welding can be prevented.

HOW TO REPLACE THE REFRIGERATION SYSTEM

  1. When replacing a refrigeration component, be sure to discharge the refrigerant system by using a refrigerant recovery system.

  2. After discharging the unit completely, remove the desired component, and unbraze the pinch-off tubes.

  3. Solder service valves into the pinch-off tube ports, leaving the valves open.

  4. Solder the pinch-off tubes with service valves.

  5. After doing the above procedures, the valve must be closed and left in place on the system for any subsequent procedures.

  6. Evacuate as follows.

  7. Connect the vacuum pump, as illustrated in Figure 31A.

  8. Start the vacuum pump, slowly open manifold valves A and B two full turns counterclockwise and leave the valves open.
    The vacuum pump is now pulling through valves A and B to valve C by means of the manifold and entire system.
    CAUTION If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump.

  9. Operate the vacuum pump for 20 to 30 minutes, until 600 microns of vacuum are obtained. Close valves A and B, and observe vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop the vacuum pump.

  10. Remove the hose from the vacuum pump and place it on the charging cylinder. See Figure 31 B. Open valve C.
    Discharge the line at the manifold connection.

  11. The system is now ready for final charging.

  12. Recharge as follows:

  13. Refrigeration cycle systems are charged from the High-side. If the total charge cannot be put in the High-side, the balance will be put in the suction line through the access valve which you installed as the system was opened.

  14. Connect the charging cylinder as shown in Figure 318.
    With valve C open, discharge the hose at the manifold connection.

  15. Open valve A and allow the proper charge to enter the system. Valve B is still closed.

  16. If more charge is required, the high-side will not take it. Close valve A.

  17. With the unit running, open valve B and add the balance of the charge.
    a. Do not add the liquid refrigerant to the Low­side.
    b. Watch the Low-side gauge; allow pressure to rise to 30 lbs.
    c. Turn off valve B and allow pressure to drop.
    d. Repeat steps B and C until the balance of the charge is in the system.

  18. When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about 2 inches from the pinch-off tool. Use sil-fos solder and solder pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.

NOTE : REFRIGERANT R134a IS USED IN SOME MODELS.
CHECK THE SPECIFICATION LABEL ON THE CABINET.

When discharging refrigerant R134a, purging instrument should be used only for R134a, without mixing that of refrigerant R22.
When checking the leakage of refrigerant R134a, leakage test tool should be used only for R134a.
The pump for discharging should be high efficiency. Final discharging value must be managed below 0.5 Torr.
Maximum water should be less than 150mg in the cycle­all tubes and H/E assembly-system.
If water quantity is over 150mg, it causes acid or corrosion in the cycle system and the capillary tube to be clogged by water and harmful materials.
Models charged with refrigerant R134a should be used dryer to prevent water from overflowing.

Equipment needed: Vacuum pump, charging cylinder, manifold gauge, brazing equipment. pinch-off tool capable of making a vapor-proof seal, leak detector, tubing cutter, hand tools to remove components, service valve.
