3. GENERAL OPERATING INSTRUCTIONS
3.1. Siting of the dehumidifier
This section describes the practical operation of the MD range of dehumidifiers.
The dehumidifiers should never be moved down slopes as they may become unstable and fall over.
To move from one level to another they must be lifted by an appropriate lifting device operated by a
competent person.
The dehumidifier should always be operated on a level surface. The compressor is not designed to
operate in an inclined plane and to do so may result in premature failure of this component.
The dehumidifier must never be placed in a position where it may be splashed with water or have
water drip onto the casing. As with all electrical equipment of this nature the dehumidifiers should
never be operated with wet hands.
Condensate is collected within the dehumidifier and then discharged via the drain hose. To ensure
that this takes place, the dehumidifier must be placed close to a suitable drain point within the
building.
The condensate discharge system is designed to operate with the hose supplied. Under no
circumstances should a longer or smaller internal diameter hose be fitted as this will impair the
ability of the units to discharge the condensate at the required rate.
If the dehumidifier is to be discharged by pump then the drain should not be more
than 2 meters above the base of the dehumidifier.
If the dehumidifier is to discharge by gravity then the hose must be laid on the floor
and taken to a drain that is below the base of the dehumidifier.
It is very important that the drain hose is not crushed or kinked. If this occurs, the pump will not
discharge the condensate, and the dehumidifier will cut out as the high condensate level switch is
operated. If this occurs the amber light on the front panel will light and the fan and compressor will
stop operating.
As the dehumidifier operates, it removes water vapour from the air within the conditioned space,
and the humidity level will gradually fall. This may result in the compressor stopping as the required
humidity level is achieved. The fan will continue to operate in order to circulate the air within the
space being conditioned.
Should the humidity then rise above that required level the compressor will cut back in. The units are
acoustically lined and whilst every effort has been taken to minimise the noise generated by the
compressor on start-up, the intermittent nature of this operation should be considered when
positioning the dehumidifiers.
The panels must never be removed when the mains power is connected. Turn the dehumidifier off
and either remove the plug from the socket or isolate the supply if access is required.
