  • Page 4: Section 1 - Introduction

    1 – INTRODUCTION Your HC-150 dehumidifier is durable, simple to operate, and needs very little mainte- nance. The HC-150 can give you years of trouble-free service if you follow the recom- mendations listed in this manual. We strongly recommended that you read this whole manual. This should not take very long.

  • Page 5: About The Hc-150

    Let’s say that you want to dry the air in a storage room, using the HC-150. Damp “pro- cess” air is pulled into the unit from the storage room. The desiccant in the Honey- ® Combe wheel picks up most of the moisture in the air. Once it has been “dried out,” the process air is vented back into the storage room.

  • Page 6: Controls And Indicators

    Temperature sensors • Electric heating elements for the reactivation air Figures 1–3 and 1–4 show some additional parts on the HC-150 unit. The Honey- Combe ® wheel is turned by a small drive motor and a toothed belt. A spring-type tensioner automatically adjusts the belt tension.
  • Page 7 The control system uses a number of sensors and controllers to supervise the activity of the HC-150. On the model HC-150I only, a Solid State Power Controller (SSP1) turns the heating elements on and off. This controller responds to a signal from a temperature sensor (TSE1) which is located in the reactivation air stream after the wheel.

  • Page 8: Protective Circuits

    The wiring for each heating element includes a fusible link. This link will open if the element overheats. If this happens, the HC-150 will continue to operate, but will not dehumidify the process air. To correct this, find the cause of the overheat condition and replace the fusible link.

  • Page 10: Section 2 - Safety Notes

    Munters is concerned about the safety of anyone who uses or services the HC-150 unit. Some of the parts inside the HC-150 can be dangerous if an untrained person tries to service the unit. Throughout this manual, we have pointed out some of the hazards which may occur in the use of the HC-150.
  • Page 11 The two blowers inside the HC-150 spin very quickly. Your hand may be hurt if you put it inside a blower while it is turning. Keep your hands away from the blowers while the unit is turned on. Do not run the HC- 150 unless both the process and reactivation fans are protected by ductwork or finger guards.

  • Page 15 POOR ARRANGEMENT Do not set up the HC-150 so it bypasses the air handling unit. The air handling unit can create back pressure. This can cause the air to flow backwards through the HC-150. HC-150 DEHUMIDIFIER HANDLING UNIT PART A...

    HC-150, and this can overload the unit. For recommendations, consult the Service Operations Department at Munters. 3.3 CONNECTING THE DUCTWORK Don’t try to operate the unit without ductwork. The unit will not be damaged, but it will not operate correctly without the proper ductwork in place. Figures 3–1, 3–2 and 3–3 show some correct installations.

  • Page 17: Connecting The Remote Humidistat

    Do not mount the humidistat near the outlet vent for the process air from the HC-150. Make the wiring connections between the humidistat and the HC-150 using 24 AWG wire.
  • Page 18 Open the process damper a bit. Wait ten minutes before checking the reactivation outlet temperature again. If it is still above 120°F, open the process damper and wait again. Continue doing this until you find the setting which causes the reactiva- tion temperature to drop to 120°F.

  • Page 19: Section 4 - Preventive Maintenance

    The HC-150 unit requires very little regular maintenance. Check these points every 30 days: 4.1 CLEAN THE AIR FILTERS The HC-150 unit includes two air filters. These are shown in Fig. 1–4. Each filter is made of expanded aluminum, mounted in a metal frame.

  • Page 20: Section 5 - Troubleshooting

    5.1 POSSIBLE TROUBLE CONDITIONS In order to check most of these trouble conditions, the HC-150 must be turned on and operating, or trying to operate. Some units are wired with remote humidistats. With this type of set-up, it is sometimes not clear whether the humidistat is trying to turn on the HC-150.

  • Page 21: Reactivation Outlet Temperature Is Too Low

    HC-150. The temperature may be too low if you try to operate the HC-150 without any ductwork. This can allow too much process air through the unit. Install a damper downstream of the process outlet.

  • Page 22: Poor Dehumidifying Performance

    A low outlet temperature can also be caused by a problem with the reactivation blower. Turn off the HC-150 and try to spin the blower by hand. It should turn freely. Model HC-150I only – There may be a problem with the overheat anticipator sensor (TS03).

  • Page 23: Checking The Heating Elements

    5.7 CHECKING THE HEATING ELEMENTS This service procedure involves an electrical hazard. Service work should only be done by an electrician who has been qualified by Munters. The heating elements are located near the intake for the reactivation air. See Fig. 1–4.

  • Page 24: Checking The Humidistat

    You should see 0 Volts across the contacts. You can also check the wiring between the humidistat and the HC-150. The humi- distat is connected to terminals on the printed circuit board. When the humidistat is not calling for dehumidification, you should see 24 VAC across the contacts.

    This will permanently damage the wheel. 11. If the wheel is still plugged, or if the honeycomb structure has softened, please call the Service Operations Department at Munters. 12. To replace the wheel, reverse Steps 2 through 6 above.
