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 13 Amps or
more, and that it is fully unwound.
Switch the unit on at the mains socket.
Turn the power to the unit on at the switch on the rear (Fig
1.) the unit will beep and the display (Fig 4) will show “--“.
The unit is in standby mode, to turn on press the mode
button (Fig 2) on the top of the unit (Fig 3).
When first turned on the heater will be in LO power mode and the
thermostat is set at 23°C (Fig 3.). Repeatedly pressing the mode button will cycle
through the running modes in order LO –HI –ECO –OFF, these
modes are described in detail further below.
Thermostat Setting: As mentioned above the thermostat is set to
the default value of 23°C, to change the desired temperature press
the or buttons (Fig 3) till the desired temperature is
achieved. The value can be between 5°C and 30°C in 1°C
intervals.
Mode Functions:
LO –LO shows on the display Fig 4.
Heater runs at LO Power (750W) till the
desired temperature set on the
thermostat is reached, at this point the
heater and fan will stop for a minimum
of 30 seconds. After this time if the
room temperature has dropped below
the thermostat temperature the unit will
resume at LO power otherwise it will
remain in standby mode till the room temperature drops sufficiently.
HI –HI shows on the display Fig 4. Heater runs at HI Power (1500W) till
the desired temperature set on the thermostat is reached, at this point
the heater and fan will stop for a
minimum of 30 seconds. After this time if
the room temperature has dropped
below the thermostat temperature the
unit will resume at HI power otherwise it
will remain in standby mode till the room
temperature drops sufficiently.
ECO –ECO shows in the display, Fig 4.
In ECO mode the unit has two separate
functions.
1. Temperature Control. The unit selects the appropriate power
according to the differential between the room temperature and
the set thermostat temperature. If the room temperature is more
than 1.5°C lower than the thermostat temperature the unit will

operate at HI power (1500W). When the room temperature is
less than 1.5°C lower than the thermostat temperature the unit
will then operate at LO power (750W). When the room is at the
desired temperature the heater and fan will stop for a minimum
of 30 seconds. After this time if the room temperature has
dropped below the thermostat temperature the unit will resume
at LO power otherwise it will remain at standby mode till the
room temperature drops sufficiently for the heater to resume.
2. Room Occupation. In ECO mode the PIR sensor is used to
detect the presence of people within the room. The unit will
operate as normal (see point 1 above) until no movement has
been detected for more than 10 minutes. After 10 minutes with
no movement the thermostat will reduce by 3°C. If after 24
hours there is still no movement the thermostat will reduce to
7°C. If at this point the heater detects movement for more than
1 minute it will beep and the thermostat will return to the set
temperature and continue operation.
Timer setting: The heater has an optional timer, to access the timer press the up
and down buttons simultaneously for more than 3s, the display will show 0.
You can use the arrow buttons to set the operating time for the unit in 1 hour
intervals between 0 - 24hrs. The display will return to normal showing the
thermostat temperature if no button is pressed for more than 5s. Once the
countdown time has elapsed the unit will switch off and return to standby mode.
When the heater is used for the first time you may notice that the unit emits a little
smoke, this is normal and will stop after a few minutes. Do not touch the air output
grille when the heater is in operation, because it will be hot and may cause burns.
Unplug the heater from the mains supply when not in use.

OPERATING COSTS
At time of going to press, the average cost of electricity is £0.13 per unit (kilowatt-
hour). The amount you are being charged will be shown on your electricity bill.
At this cost, the EH1668 will cost £0.09 per hour to run at the low setting and £0.19
per hour on the hot air setting. Use of the thermostat and eco function will reduce
this figure.
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 washing-up 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.
The EH1668 has a dust filter fitted to
the air intake on the rear of the unit. To
clean follow the instructions below;
1. Remove the 2 screws holding
the filter cover in position
2. Pull cover gently away from
the rear of the unit.
3. Gently clean the foam filter,
this can be done using warm
water with a small amount of
detergent added.
4. Thoroughly air dry the filter
foam and replace in heater.
5. Replace the screws holding
the cover in position.
If the mains lead is damaged, it must be replaced by the
manufacturer or an 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".
Make sure that the cord-grip is positioned correctly
(over the outer sheath of the cable) and it fully tightened.
If the plug is fitted with a 3 A or 5 A fuse, replace it
with a 13A fuse.

FAULT-FINDING
The EH1668 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.
If there appears to be excessive dust or dirt build up on the air filter refer to
maintenance section above on how to clean.
Reconnect to the mains supply and operate as per the user instructions for the LO
heatsetting.If the fan operates, then it is safeto select the high heat or ECO setting.
If the fan does not operate, or overheat protection switch operates again, contact
an authorised service agent for repair.
The EH1668 has an additional tilt switch to prevent the unit being powered up in
any other position than upright. If the unit does not operate ensure it is placed on a
firm level surface and is not tilted in any way.
