Product- and functional description

Introduction

This section will give you a description of the CDF 10 and its functionality.

Description of function

CDF 10 is working in accordance with the condensation principle. The humid air is drawn into the unit by a fan. When passing through the evaporator the air is cooled down to below dew point and water vapor is condensed into water, which is drained away. The now dry air is then passed over the condenser coil where the air is heated. As a result of the released evaporator heat and the working energy of the compressor being turned into heat energy, more heat is returned to the air than was previously extracted. This extra heat corresponds to an approximate increase in temperature of 5 °C. The repeated circulation of air through the unit reduces the relative humidity, giving very rapid but gentle drying.

Air flow

The following illustrates the air flow:

Built-in hygrostat

The dehumidifier is controlled by a built-in hygrostat that is set to approx. 60 % RH. When the hy-grostat registers a relative humidity of more than 60 %RH, the compressor and the fan automatically switch on and the dehu-midifier starts to dehumidify. The front panel has to be removed before adjusting the hygrostat. The hygrostat is located under the control box and can be adjusted by turning the set screw.

Product- and functional description, continued

Built-in hygrostat, continued	OBS! If the air humidity is below 60 %RH, the unit will not start when the power is connected. If you want to set the hygrostat at a lower relative humidity than 60% the set screw has to be turned clockwise.We recommend installing an external hygrostat if you want to change/adjust the setting of relative humidity very often.
LED indication/switch	The LED on the front of the unit is green when the compressor is operating, and the unit dehumidifies.The dehumidifier is switched on and off by the switch on the side.Note! Any stop of the unit - either caused by failing power connection, by the switch on the side of the unit, by the hygrostat, or by the water tank's water stop function - will make the electronic control put off re-start for 45 seconds in order to protect the compressor from being switched on and off repeatedly.
Compressor control	At compressor start, the solenoid valve opens up for at least 10 sec. in order to relieve the pressure on the compressor starting circuit.Any stop of the unit - either caused by failing power connection, by the switch on the side of the unit, by the hygrostat, or by the water tank's water stop function - will make the electronic control put off re-start for 45 seconds in order to protect the compressor from being switched on and off repeatedly.
Defrosting	If the temperature falls to below 20 °C the evaporator may start to ice up after a short time.The defrosting function is activated when the evaporator sensor registers a temperature lower than 5 °C, after which the control will let the unit operate in dehumidification mode for another 44 minutes. Then the fan is stopped, hot refrigerant is bypassed the condenser and is finally led through the evaporator where it melts the ice. When the evaporator sensor registers that the temperature is above 5 °C, the fan starts again.
Safety circuit	If the temperature on the condenser coil increases to a temperature of more than 55 °C (for example in case of fan failure), the compressor is stopped automatically to avoid any damage. After 44 minutes the compressor starts again automatically.At room temperatures lower than 3 °C and higher than 30 °C the unit is automatically switched off to protect the cooling plant against icing up or superheating. When the temperature is higher than 3 °C or lower than 30 °C the dehumidifier will automatically start again. The temperature is registered by a sensor on the PCB.
Water tank	If it is not possible to mount a fixed or a flexible drain outlet connection, the CDF 10 can be used with a water tank.If the CDF 10 is used with a water tank, it switches off automatically when the water tank is full. A red LED on the front panel flashes when the water tank needs to be emptied.The water tank is an extra accessory for the CDF 10 and is available on demand.The water tank consists of the following parts:Water tank cabinet with magnetic switch for water stop and cable for connection to PCBWater tank4 machine screws

Mounting and installation

Suspension

The wall suspension bar supplied with the unit is fixed to the wall and the dehumidifier is hung up on it. It is important to mount the unit in a horizontal position to secure correct outflow of the condensate water.

The dehumidifier must be placed in a way that allows unimpeded air intake through the front and outlet through the grill on the sides. Be sure always to leave at least 100 mm free space around the unit for optimum operation.

It is important that the dehumidifier is not installed near a source of heat as for example a radiator, and doors and windows must be kept closed when the dehumidifier is in function.

Installation of the water tank

1. Place the CDF 10 on the wall by means of the wall suspension bar.
2. Then dismantle the front panel of the CDF 10.
3. Fix the water container cabinet by 4 machine screws under the bottom of the CDF 10.
4. Take the supply cable through the diaphragm bush at the bottom of the water tank cabinet.
5. The control of the CDF 10 is placed in a box behind the front panel. To get access to the control, unscrew the 4 screws on the sides of the box and remove the box lid.
6. Take the cable from the magnetic switch through the diaphragm bush at the bottom of the CDF 10 and connect it to the terminal strip on the PCB - terminal points 13/14 (WATER SW).
7. Remount the control box lid and the front panel.
8. Place the water tank in the water tank cabinet. The float must be turned towards the magnetic switch.

Mounting and installation, continued

Note	On the rear of the unit a cable binder protects the compressor during transport. This cable binder must be removed before suspension and power connection
Condensate outlet	The condensate outlet is located at the bottom of the dehumidifier. The unit has a drain spigot intended for connection of a 1⁄2” flexible or fixed water connection. If water drain through the wall is chosen, a suitable hole is made in the wall and the condensate hose is led out through this hole, before suspending the dehumidifier on the wall suspension bar.As an alternative a condensate pump can be fitted at the water outlet to pump the water to a drain.
Placing of the condensate outlet	The placing of the condensate outlet is shown on the drawing:
Connection of power supply	The unit is delivered complete with cable and plug for connection to 230V/50Hz.Power is connected to the unit in accordance with the nameplate. Please refer to the wiring diagram on page 111.Note: All electrical connections must be made in accordance with local power supply.

Service guide

Access to the control	Remove the front panel by unscrewing the two screws on the top of the dehumidifier. Lift the front panel vertically upwards and then pull it horizontally away from the unit. The control of the unit is located in a box behind the front panel. To get access to the control unscrew the 4 screws on the sides.
Maintenance	The dehumidifier requires very little attention for trouble free running. All the necessary safety and control functions have been built in. The fan motor and the compressor have permanent lubrication and require no particular maintenance.
Cleaning of the dehumidifier	Once a month	Once a year
	Once a month the air inlet filter should be checked and cleaned if necessary. The front cover panel is removed and the filter taken out. Clean the filter in tepid soapy water or if not badly soiled by vacuum cleaning	Once a year the front cover panel should be removed in order to check the inside of the dehumidifier. If the dehumidifier is dirty it should be cleaned by vacuum cleaning. The condenser in particular should be thoroughly vacuumed. If the tube evaporator is badly soiled, it may be washed in tepid soapy water
