1.1. ELECTRICAL SAFETY

p WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other
connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices.
A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual
Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not
protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey
dealer.
You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the
safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the
power supply. See 1.1.1. and 1.1.2. and use a Portable Appliance Tester.

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all
connections to ensure that none are loose.

1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply
to be used and that the plug is fitted with the correct fuse - see fuse rating at right.

1.1.7. DO NOT pull or carry the appliance by the power cable.

1.1.8. DO NOT pull the plug from the socket by the cable.

1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty
item repaired or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is
damaged, cut the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.

b) Connect the BROWN live wire to the live terminal ‘L’.
c) Connect the BLUE neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation
extends beyond the cable restraint and that the restraint is tight.

Double insulated products, which are always marked with this symbol , are fitted with live (brown) and neutral (blue) wires only. To rewire,
connect the wires as indicated above - DO NOT connect either wire to the earth terminal.

1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure
that a suitably rated supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket
with your electrician.

1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance
plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use
of 2.5mm² section cable.

Efficiency of the dehumidifier is influenced by the air outside the room. For operating efficiently, try to avoid opening and closing the windows
and doors. For best performance, operate the dehumidifier within the usable operating temperature.

3.1 Operation

3.1.1 Plug the unit in to the mains socket, a beep will be heard when inserting the plug.

3.1.2 Press the "ON/OFF" switch and the operation light will illuminate, the humidity display will light to display the previous set humidity. The initial
setting for humidity is 60%, after 3 seconds the display will show the current humidity.

3.1.3 Press the humidity up or down buttons to adjust to the desired humidity required. If the required humidity is 3% below the current humidity the
unit will start automatically, if the set humidity is 3% more than the current humidity the dehumidifier will automatically stop.

3.1.4 The unit has a memory function. Use the humidity up and down buttons to adjust to the desired setting and then press the memory button
to record the setting, each time the machine is switched on it will automatically run at the required setting.

3.1.5 When setting the humidity to less than 30%, the unit will run continuously and the display will read "CO".

3.1.6 To shut the dehumidifier down press the "ON/OFF" switch.
Note: If the humidity setting is greater than the current humidity the unit will not run.

p WARNING! The fan motor and compressor must run for at least 3 minutes while dehumidifying.
7 DO NOT start the dehumidifier immediately after shutting down, allow 3 minutes before restarting.

3.2 Defrosting Operation

The evaporator within the dehumidifier frosts during the dehumidifying operation at a room temperature of approximately 15°C or less. The
defrosting device works automatically at an interval of approximately every 30 minutes for a duration of approximately 5 minutes. The
dehumidifying function will stop during the defrosting operation. Do not disconnect the plug or turn off the unit during the defrosting operation.
Note: This dehumidifier does not have a cooling function, it produces heat during the operation and room temperature will rise by 1°C to 4°C. The
temperature gets higher while it is operated in a closet, or similar. Furthermore, room temperature will rise because doors and windows are
closed and heat is produced from other appliances in the room and from sun radiation.

3.3 Emptying the Water Collection Tank

During the dehumidifying operation, water is collected in the water collection tank. When the tank is full of water, the dehumidifier stops
operating automatically and the warning buzzer beeps twice. The unit will not restart until the water collection tank has been emptied.

3.3.1 Open the door and remove water collection tank from the dehumidifier by pulling it gently outwards by holding the sides of the tank (fig.3).

3.3.2 Hold the tank by the handle and carry it carefully to an emptying point.

3.3.3 Remove the plug at the bottom of the tank and slowly empty the water out of the tank.

3.3.4 Replace the drain plug and refit the tank in the dehumidifier, making sure it is properly back in place as the unit will not restart if it is not fitted
correctly.

3.4 Continuous Draining

3.4.1 If there is a place suitable for draining, continuous draining can be carried out. The continuous operation enables the dehumidfying operation
to continue uninterrupted.

3.4.2 Turn off the dehumidifier, disconnect the power plug and remove the water collection tank.
