Please, read and follow the instalation and operating instructions carefully, to ensure the long life and reliable
operation of this appliance.
Kospel S.A. may make minor changes if necessary, in the appliance, that will not be shown in the operating
instruction, so long as the main features of the heater remain the same.

ENG-003B 3
You must not install this
appliance in places exposed
to the danger of explosion and
places in which the temperature
may go down below 0°C.
The EPJ.P Instantaneous Water Heater provides hot under the shower. It can be installed either over a bath or
inside a shower cabin. 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 heater features:
- tubular heating coils that assure maximum safety
- materials resistant to corrosion and chemically inactive with water (copper, brass, stainless steel, plastic)
This appliance will work with
the attached tap set only.
The tap set works as an air vent
and therefore, cannot be con-
nected to any valve or a connec-
tor that is not recommended by
the manufacturer.
You must not install in direct
vicinity of the range of spray of
the spray-head.

All installation work has to be
carried out with the electricity
and water supplies cut off.
Recommendation
- the appliance connect to cold
water supplies only
- do not install the spray- head
holder above the heater
- install the spray-head holder on
the same wall where the heater
is installed
Installation - Assembly
1. Fix the mixer [19] on water sup-
ply pipe [15].
2. Undo the two screws[9] and take
the front case [27] off.
3. Connect the mixer by the use of
metal pipes with the heater in
order to mark the fixing points
for the screws [32].
4. Drill holes at the marked places,
insert the screws [32] in there.
5. Insert electric wires into the
heater through the stuffing [5]
picture 5.
6. Install the heater onto the wall.
7. Connect the mixer and the sho-
wer set with the heater.
8. Connect electric supplies accor-
ding to Diagram 2.
9. Fix the front case and screw it up.
10. Install the shower holder.
11. Let the mains water pressure to
get to the mixer.
12. Check connections for leaks.
13. Vent the installation.
14. Switch electric supplies on (fuses).

Electric connection and anti-electric shock protection test has to be carried out by a
qualified electrician.

1. Shut off electric supplies.
2. Turn the flow on (turn the hot water tap on) in order to vent the water installation (for about 15-30
seconds), until the flow of water becomes constant and even.
3. Shut the flow.
4. Switch the electric supplies on.
Do it each time after a decay
of water.
If venting is not carried out,
the heater may be dama-
ged.
Venting

ENG-003B 7
By the term "flow regulation" we mean the setting of the water temperature
to a comfortable level, by means of limiting/opening the rate of flow.
For this purpose,carry out the following steps:
- insert the spanner [25] into the regulation valve [4],
- set the hot water tap at maximum flow,
- set optimum flow(check if the temperature is comfortable for you) using
the spanner [25],
- shut water flow using the tap,
- take the spanner[25] out of the regulation valve [4].

Chart 3 Characteristics
This heater has a differential pressure switch that starts heating automa-
tically when there is a proper rate of flow through the tap. There is a red
indicator light on the front case that shows that heating is on.
The characteristics shows the dependence between temperature rise
and flow rate per minute. The greater the flow rate the lower temperature
of the water.
4
Get rid of boiler scale from the
spray-head on regular basis.
Boiler scale may appear in the holes of the shower spray-head. Undo the spray-head and clean it with a hard
brush.

Safety temperature limiter [3]
protects against overheating. After
the limiter goes off, you can turn
the hot water tap on but heating will
not start.
Resetting the safety temperature
limiter should be carried out by an
authorised service.

In case the appliance does not heat water, check for possible reasons:
Diagram 6 Wiring diagram
E1 - heating box [1]
Q1 - differential pressure switch [2]
F1 - safety temperature limiter [3]
H1 - heating indicator [24]
- a failure of mains supplies(e.g. fuses),
- insufficient flow through the heater (e.g. incorrect setting of the flow regulating valve) - refer to "Flow regula-
tion".
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.
