Fault Finding; Maintenance - Prem-I-Air EH1644 Manual

OPERATING COSTS
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 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.
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".
13A
• 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.
