Please, read and follow the installation and operating instructions carefully, to ensure the long life
and reliable operation of this appliance.
The manufacturer may make minor changes in the appliance if necessary. They will not be exposed
in the operating instruction, so long as the main features of the heater remain the same.
EPS electric instantaneous water heater is designed to heat domestic water in households, sanitary
rooms, labs, plants etc., in other words, everywhere where there is a demand for instant hot water.
Turning the hot water tap on, automatically starts up the heater (a red light on the heater’s outer case
comes on). Water is heated instantly as a result. The temperature of heated water depends on the rate
of flow: the greater the flow, the lower the temperature. Turning the hot water off, shuts the appliance.

- the appliance can be used only after proper installation (and make sure that it is in a faultless
technical condition!)
- the appliance should be vented (see “Venting”) before the first use and each time after emptying
the heater out of water (e.g. during conservation of a water supply system),
- be alert not to let the working appliance be emptied of water, which may happen with the shortage
of water in a water supply system,
- do not open the front case of the water heater while it is in on,
- do not either install any additional appliance to the tap pipe or plug it while water is flowing,
- remember that water at 40°C temp. may bring forth the feeling of burning (especially in case of
children).

Installation
1. Fix the tap set [6] on a water supply pipe [8].
2. Connect the heater to the tap body [8] with nuts [10] accompanied by gasket [4] and the filter [5].
3. Allow water mains pressure gets to the tap.
4. Check for leaks by opening the tap. Do it without the spray-head [9] on, as some impurities, which
come from the installation, may appear.
5. Vent the water installation.
6. Put the spray-head on.
7. Connect the heater to a power source (through the installation cable box according to Fig.2).
Recommendation
- connect the appliance to cold water supplies only.
ATTENTION!
Electric installation should be equipped with safety (power-differential) circuit breaker and
other devices which will ensure disconnecting the heater from the source of power (intervals
between all their poles should not be less than 3mm).

Venting
1. Shutoffelectricsupplies.
2. Turn the flow on (turn the hot water tap on) in order to vent the installation until the flow of water
becomes constant and even.
3. Shut off the flow.
4. Switch on the electric supplies.
ATTENTION!
Vent the appliance every time after a decay of water.
Operation
The heater is produced in 2 versions: with and without power changing knob (Fig.4 and Fig.3 re-
spectively) which is placed on the front cover.
There are 2 possible positions that the knob can be situated. In “(“ position the appliance uses lower
power than in a position “)) ” – in that case the maximum power is used. The knob is easily turned in
both directions.
ATTENTION!
In case of water shortage the tap should be shut immediately. The appliance should be vented
as soon as a water supply is back (see ‘Venting’).

Maintenance
5
To ensure a long and faultless work of the appliance you should carry out a seasonal cleaning of the
filter [5] in your individual capacity (this duty does not belong to a guarantee service).
To clean the heater do the following (Fig.5).
1. Cutoffwaterandelectricsupply.
2. Disconnect the heater from the tap set (see ‘Installation’).
3. Take the filter out [5] from the fittings at cold water inlet [12].
4. Clean the filter.
5. Install the filter into the former position.
6. Fix the heater on the tap set.
7. Turn on the cold water tap on – check connections for
leaks.
8. Vent the installation (see ‘Venting’).
ATTENTION!
The filter should be cleaned after the repair of a water system, when a lot of effluent appears
or after a year of operation.

The guarantee does not cover the above repairs.
If there is a fault in the appliance (the heater does not work and all the above reasons do not occur),
contact the nearest authorised service.
