Page 14: Transport And Unpacking
The units are separately packed in cardboard boxes, on one pallet tied with tape. To prevent damage to the unit, it is recommended that the unit is transported to its final destination IN its packing. When the unit is stored temporarily, it must be stored in a dry place until transport to its final destination Smaller units can usually be moved by manpower and/or using a trolley. -
Page 15: Installation Directions
Supporting material must be sufficiently strong To prevent resonance, make best use of sound insulating material – see wall mounting kit. Fitting or attaching the unit to wooden floors or walls is not recommended. This requires special precautions (anti-rumble materials). -
Page 16: Wall Mounting
If you are mounting the unit against the wall, we advise following directions: leaving a clearance of minimum 20 cm (*) from the floor – thus assuring enough air flow at the suction side - and minimum 1 m from the ceiling, thus avoiding that the unit will re-suck its own dried air. ... -

GENERAL Type of unit 92M-100 140-142M Nominal output * Nominal flow Pressure loss 1,68 2,64 5,94 * At 80/60°C WT° and 20°C LT° Used to keep the ambient area to temperature or bring this to temperature depending on capacity. The hot-water battery (LPHW) is fitted on the pulse side of the unit. The connection of the LPHW is on the left of the unit. -
Page 19: Electrical Heating
GENERAL Type of unit 92M-100 140-142M Output 3 - 6 Used to keep the ambient area to temperature or bring this to temperature, depending on capacity of the heating resistors. Composed of reinforced resistors of 1, 1,5 or 2 kW RUS321 with ribs of galvanised steel. Including one-stage control with run-on delay on the fan and excess temperature protection. -
Page 20: Swimming Pool Condenser
GENERAL Makes sure that the unit will keep working at a higher ambient temperature than the standard value – see technical specifications – and discharges the surplus heat to the swimming pool water. HYDRAULIC CONNECTION If the unit is fitted with a swimming pool condenser, this must be connected via a bypass or a separate pump to the return circuit line from the filter installation. -
Page 21: Outdoor Condensor
GENERAL To be used when a swimming pool condenser offers no solution to the problem of excessive heat discharge. COMPOSITION several rows of copper pipes (3/8”), with pressed-on aluminium plates, in a housing of galvanized steel plate, epoxy varnished. ... -
Page 22: Electrical Data And Supplies
GENERAL All units are equipped with an electric switchboard cabinet with control circuit board, compressor relay and connection terminals. External control equipment should be ordered and installed separately. All controls are 24VDC and thus of the ultra low safety voltage type. The units are fully pre-wired and constructed to CE standard. -
Page 23: Switchboard Cabinet
THEY ARE THEREFORE NEVER OUR RESPONSIBILITY. COMPONENTS All components used – except the circuit board (CDH product) - are standard electrical components. They can be replaced easily thanks to their mounting on DIN rails. Equivalent types must replace the relays used. -
Page 24: Start Up, Safety Regulations And Maintenance
GENERAL As soon as the unit is installed according to the guidelines, the power can be connected. Before connecting the dehumidifier, the ambient temperature must be checked. This must be higher than 10°C so the unit can be provided with enough warm air to be able to defrost. Connect the unit manually by turning the HYGROSTAT to a lower value. -
Page 25: Safety Regulations
FROST The unit must be protected against frost. When currentless, the LPHW can freeze. PROTECTION VOLUME All units must be placed outside the protection volume as specified in European standards. UNITS THAT ARE PLACED INSIDE THE PROTECTION VOLUME, MUST BE CONNECTED TO AN ISOLATING TRANSFORMER OR BE DOUBLE INSULATED. Hygrostats, thermostats and similar connected to the circuit board (24 VDC) are the ultra-low safety voltage type and can be placed inside the protection volume. -
Page 26: Failures
Hygrostat adjusted too high Adjust hygrostat at normal value = 60% Check the hygrostat on its action. Hygrostat defective When defective, replace it. Before replacing the fuses, first determine the cause. 6.3 A glass fuse on PCB faulty: replace by a fuse of the same value. Check Glass fuses defective 230V exit on the PCB relay. -
Page 27: Other Failures
In cold weather, damp spots can form on the cold bridges. The hygrostat may Hygrostat set to normal value, not be turned down but this is not a good solution: the unit will work for too long. It is defective and damp spots appear. recommended that the cold bridges be insulated.
