  • Page 3: Introduction

    1 Introduction This manual includes installation, operation, and troubleshooting instructions for the HCU unit. The ® engineers at Munters DryCool have designed the HoneyCombe dehumidifier using state-of-the-art technology. The unit is durable, simple to operate, and needs very little maintenance.

  • Page 4: Safety

    2 Safety Munters is concerned about the safety of anyone who uses or services the HCU unit. Some of the parts inside the HCU can be dangerous if an untrained person tries to service the unit. Throughout this manual, we have pointed out some of the hazards that may occur in the use of the HCU. We have also listed the precautions that you should take to avoid these problems.

    incorrectly wired. 3.7 CONNECTING THE CONTROL SYSTEM The unit is controlled by a Novar IOM or Danfoss controller with relay outputs. Digital inputs monitor faults. With this method of control, the fan relay on the IOM turns the unit on. The relays on the BMS IO card call for stages of cooling, dehumidification and heating as conditions require.

  • Page 8: Operating Instructions

    4 OPERATING INSTRUCTIONS 4.1 CONTROLS The unit is controlled and monitored by a Novar IOM or Danfoss controller. The HCU has a microprocessor to supervise and control all internal functions. The IOM provides eight dry contact closures to control the supply fan and stages of: cooling, dehumidification, and heating as shown on the wiring diagram.

  • Page 28: Troubleshooting

    6 TROUBLESHOOTING The HCU has state-of-the-art design, with a sophisticated control system using a microprocessor with solid-state electronics. This unit has proven to be very reliable in a wide variety of installations. Features exist that facilitate troubleshooting on the occasion that a problem occurs. 6.1 DEHUMIDIFIER Operating Principle Figure 6-1 shows how the HCU removes moisture from the air.
  • Page 29 The HoneyCombe® wheel has been carefully designed. The honeycomb material is nonmetallic and does not react to bacteria. The desiccant material is made of silica gel, and depends on the “adsorption” principle. As moisture collects, each particle of the gel can bond with a large number of water molecules. The process can be reversed by adding heat.
