ELECTRICAL CONNECTIONS
The DMD36 has AUTO SENSING DUAL VOLTAGE selection circuitry as standard, and can be
connected into a standard 16amp 110v, or 13amp 230v supply once the correct plug has
been fitted.
To reduce the risk of electric shock, it is recommended to use a suitable RCD (residual
current device.
230 Volt Mode
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved
13 amp BS 1363 plug, or a suitably fused isolator switch.
WARNING! THIS APPLIANCE MUST BE EARTHED
IMPORTANT: Wires in the mains lead are coloured in accordance with the following code:
Green & Yellow .......... Earth
Blue .............................. Neutral
Brown .......................... Live
As the colours of the flexible lead of this appliance may not correspond with the coloured
markings identifying terminals in your plug, or your mains supply, proceed as follows:
• Connect GREEN & YELLOW coloured cord to plug terminal marked with a
letter “E” or Earth symbol “ ” or coloured GREEN or GREEN & YELLOW.
• Connect BROWN cord to terminal marked with a letter “L” or coloured RED.
• Connect BLUE cord to terminal marked with a letter “N” or coloured BLACK.
Fuse Rating
The fuse in the plug must be replaced with one of the same rating (10amp) and this
replacement must be ASTA approved to BS1362.
110 Volt Mode
These models MUST be connected to a protected 110V supply, through a suitably approved
BS4343/IEC309-2 connector, . On no account must a 230V, 13amp (BS1363) plug be used.
NOTE: If a portable 110V transformer is used, make sure it has a rated capacity sufficient to
take the load of the unit.
In the event that the unit is hard wired into the electrical system, it must be carried out in
accordance with IEE regulations.

INSTALLATION
Little installation is required other than siting the dehumidifier on a firm, flat and level surface,
locking the castors to prevent the unit from moving, connecting to the main electric supply
and choosing the method of disposing of collected water.
This equipment is designed to work in temperatures between 5ºC & 35ºC , Never operate in
temperatures below 5ºC or above 35ºC, if the temperature in the room rises above 35ºC,
switch the unit OFF. Failure to switch OFF could cause the compressor to overheat, resulting
in premature failure.
If used in temperatures below 5°, the coil may frost up and no water will be produced until
the defrost cycle commences.
NOTE: if using an extension lead, ensure it is correctly rated for the inductive load, fully
unwound and never run through water or over sharp edges.
OPERATION
Never attempt to use the dehumidifier for anything other than it’s intended purpose.
The DMD36 is fitted with an electronic hour run counter which is not resettable. Before
switching the dehumidifier ON, take a note of the hours run counter to assist with monitoring
the amount of time the unit is run.
After moving the dehumidifier into the location to be used, allow the unit to stand for 15
minutes before switching it on.
Ensure all doors and windows are closed and the area sealed where possible, this aids to
speed the dehumidification/drying process.
Plug the unit into the power supply and switch the supply ON.
Switch the unit ON by depressing the ON/OFF switch marked I/O, I= ON, O=OFF. The ON/
OFF switch is located next to the hour counter.
The dehumidifier is now running, allow a minimum of 10 mins for it to begin dehumidifying/
drying.
The water collected can be drained automatically using a suitable length of hose (not
supplied) connected to the outlet port, ensure the hose is kept below the outlet port for its
entire length, otherwise flooding of the unit will occur.
Alternatively the collected water can be drained into a suitable container ( builders bucket
or similar). It is important to keep an eye on the water level in the bucket and empty regularly
to prevent it from overflowing.

MAINTENANCE
ALWAYS disconnect the unit from the power supply before carrying out any maintenance
activities.
These dehumidifiers are fairly maintenance free, only requiring periodic cleaning. All internal
parts sealed and lubricated for the life of the unit.
The drip tray can be cleaned using a clean dry soft cloth, DO NOT use harmful chemicals or
cleaning agents. Simply lift the drip tray slightly to disengage it from the retaining lip then
pull it out.
The cooling coils require cleaning at least once a month, more often if the unit is used in
dusty environments. In order to do this, it is necessary to remove the top cover, complete
with handle.
Remove all 8 cover securing screws, and carefully pull off the cover.
Clean the inside of the unit by carefully blowing out any dust using compressed air at a low
pressure.
Pay particular attention to the fan blade and motor, ensure the motor spins freely.
Reassemble the unit in the reverse order.
IMPORTANT
When carrying out maintenance activities, precautions to ensure the safety of yourself and
that of others around you must be considered, i.e. choose a location where it is safe to use
compressed air to blow the unit out, and always wear safety glasses and ear defenders.
STORAGE
Switch OFF the power supply and disconnect from the main electrical supply by removing
the plug from the socket.
The unit should not be moved for at least 15 minutes after switching off.Always ensure the
drip tray is clean and dry before storing.
If the storage period is expected to be prolonged, remove the top cover as described
above, and blow out the coils and internal parts. Ensure the coils are clean and dry before
replacing the cover.
