INSTALLATION

For free-standing use: attach the feet to the underneath of the heater using

the four 12mm (½") screws. The feet fit over the pre drilled holes in the
case approximately 95mm from the end of each side.

To wall-mount: Referring to the diagrams below, draw two horizontal lines
on the wall 330mm apart, the lower line more than 50mm from the floor.

On the upper line, drill holes 310mm apart, using a 6mm (¼") masonry bit,
and insert a wall plug in each hole.
On the lower line, drill holes 435mm apart centred directly below the upper
holes using a 6mm (¼") masonry bit, and insert a wall-plug. See Fig 2.

Insert the 30mm screws into the upper holes and tighten to within 8mm of

the wall. See Fig 2.

Slot the 2 hook brackets over the upper 2 screws and tighten to secure to

the wall. See Fig 3.
Fix the two L-shaped brackets to the underside of the heater using the

12mm screws through the round hole in the bracket - the oval hole in the
bracket locates over the screw that fixes the case together approximately
95mm from the case side at the rear of the unit.

Hang the heater on the hook-brackets using the two 25mm slots.

The L-shaped brackets will now line up with the lower holes in the wall.
Attach to the wall using the other two 30mm screws. See Fig 4 below.

PAT TESTING

Fan Switch

Power
Switches

When used in an office environment, this product should be safety-tested
yearly by a qualified electrician (PAT Tested).

We recommend that it is PAT tested regularly when used in a domestic
environment.

GENERAL SAFETY REQUIREMENTS

Domestic wiring must be tested periodically by a qualified electrician at
least once every 10 years or at every change of occupancy.

For office and retail premises, and buildings such as village halls, the wiring
must be inspected at least once every 5 years.

It is recommended that all building be fitted with smoke alarms (it is
mandatory for new buildings).

OPERATION

Plug the mains lead into a 13 Amp mains socket.
If connecting via an extension lead, make sure that

the lead is rated at 10 Amps or more, and that it is
fully unwound.

Switch the unit on at the mains socket.

All the following controls can be operated via the
control panel or the remote control.

Switch the unit on by pushing the On/Off button
The unit will beep to show it is powered on and

ready.
The display will show the room temperature.
To set the desired room temperature first press the Temp button

then the Plus or Minus Button to increase or decrease the
desired room temperature. Holding the Plus or Minus buttons for approx.
3s will cause the display to change at a faster rate.

Select the required heating power by pushing the Heat button then
the Plus and Minus buttons. The power options are as follows;

Eco = 750W the unit will beep once.
Comfort = 1250W the unit will beep twice.
Super = 2000W the unit will beep three times.
The fan can be operated at any time by pressing the Fan Button,

pressing once will turn the fan on and again will turn it off.
The heater will now operate at the desired power level till the set

temperature is reached, the unit will turn off and only turn on again if the
temperature drops below the set level.

Do not touch the air output grille when the heater is in operation, because
it will be hot and may cause burns.

If the unit is switched off at the panel or the mains supply the settings will
revert to their default values (Temp = 24°C, Timer = OFF, Heater = OFF).

Unplug the heater from the mains when not in use.

USING THE TIMER

To operate the unit on the 24 hour timer the unit must be plugged in and a
power setting, temperature selected. If the unit is turned off at any time
the clock will stop and reset. The timer is a simple count down timer and
will count down from the set time till zero (between 30min and 24 hours)
when it will turn off the heater. To set the timer press the Timer
Button then the Plus or Minus buttons to increase or decrease the required
operating time in 30 minute steps. The unit will then operate for the set
time, the timer on the display will count down to zero then turn off,

USING THE THERMOSTAT

The thermostat can be used to regulate the room temperature between
5°C and 37 °C.

Turn on the heater and set to maximum power and maximum temperature.
The heater will then operate at maximum output. When the desired

temperature is reached reduce the Temperature setting on the display by
pushing the Temp button and then the minus button till a click can be
heard. The heater will then switch on and off to keep the room at the
desired temperature. Either the "Eco-750W", "Comfort-1250W" or the
"Super-2000W" setting may be used.

If the temperature control is set to 5 °C, it will operate as a "frost-stat" and
switch the heater on if the temperature drops below 5°C, preventing
damage by frost.

OPERATING COSTS

13A

At time of going to press, the average cost of electricity is £0.12 per unit
(kilowatt-hour). The amount you are being charged will be shown on your
electricity bill.

At this cost, the EH1644/EU will cost £0.09 per hour to run on the "750W"
setting, £0.12 per hour to run on the "1250W" setting and £0.24 per hour
to run on the "2000W" setting with the thermostat set to its maximum.

If the thermostat is used to regulate the temperature the operating costs
will be lower, depending on the room temperature.

FAULT-FINDING

The EH1644/EU has an overheat protection switch, which disconnects the
power if the element gets too hot. The usual reason for this is because the
air-flow has been obstructed, or the grilles have been blocked. If the heater
ceases to operate, leave it for 20 minutes to cool down, then check that the
grilles are not being obstructed.

Switch back on, and check that the unit is operating normally. If not, contact
an authorised service agent for repair.

If the unit is turned off at any time the thermostat will reset to 24°C, if the
room temperature is above this level the unit will not operate. Adjust the
thermostat to the desired temperature.

MAINTENANCE

Before cleaning, turn the heater off, and disconnect from the mains supply.
The heater may then be cleaned using a damp cloth with a drop of washing­up liquid to remove any dust or dirt from the case. Do no use stronger
detergents or solvents as these may damage the paint finish.

Using a dry 1" (25mm) paint-brush, remove any dust from the grilles.
If the mains lead is damaged, it must be replaced by the manufacturer or

and authorised service centre. If the mains plug needs to be replaced,
proceed as follows:

• Connect the brown wire to the terminal labelled "L".

• Connect the blue wire to the terminal labelled "N".

• Connect the green/yellow wire to the terminal

labelled with the earth symbol or "E".

• Make sure that the cord-grip is positioned correctly
(over the outer sheath of the cable) and it is fully
tightened.
