This appliance must not be
installed in a place which is
exposed to the dangers of frost
or explosion.
The EPO.D provides hot water wherever it is required whether it is in the home, in a workshop, a public facility
or in a laboratory. It is compatible with most taps available in the market. This pressure type heater has to be
installed with inlet and outlet pipes at the top of the heater. The temperature of the heated water depends on the
rate of flow and the power of its heating coils. The higher the rate of flow, the lower temperature of the water.
Turning the hot water tap on, automatically switches the heater on which heats the water in accordance with the
following technical specifications.
The heater features:
- covered (insulated) heating coils that assure maximum safety;
- materials resistant to corrosion and chemically inactive towards water (copper, brass and stainless steel).

No filter[12] on water supply
(picture 3) can damage the
heater.
This appliance should be instal-
led and started-up by a profes-
sional person.
This heater must be installed
with the outlet and inlet pipes
at the top.
Electric and water supplies have
to be cut off during any installa-
tion work.

Recommendations
- as an economy measure the he-
ater should be installed close to
the most frequently used tap;
- the appliance can be connected
to a cold water supply pipe
only;
- a non-return valve cannot be in-
stalled on the supply pipe;
- inlet and outlet pipes should not
be made of plastic;
- the heater works in conjunction
with taps and mixers without a
thermostat.
Assembly
1. Bring the domestic water and
the electricity supply, observing
normal safety standards, to the-
point where the heater is to be
mounted. Diagram No.2 shows
how to connect the heater with
the water installation.
2. Remove the heater's outer case;
undo the screws [16], slide the
case off starting from the top.
3. Fix the heater on supplied hooks
after inserting the electric wires
through the entry access [14].
4. Connect cold water [ZW] to the
inlet pipe[7] inserting a filter
in between[12]; connect hot
water outlet[8] to a pipe [CW]
(picture 3).
5. Flood the heater with cold water
and check connections for le-
aks.

7. Connection to a three phase installation should be made in accordance with the diagram 4b
In this case the appliance is supplied from two phases. First, you have to take off the bridge M1.
8. Fixing the outer case: slide the case into position on the base. Start from the bottom, and push into place,
then secure with screws.
9. Make sure that the appliance has no access through the entry for electric wires at the back base to live
parts.

If the appliance is supplied from
two phases, the bridge M1 (con-
necting terminal clamps U and
V) installed by Kospel has to be
taken off.
6. The appliance is set at single phase supply (it is equipped with a bridge[M1] connecting terminal clamps U
and V).The single phase electric connection should be made according to the diagram 4a

Picture 5 Flow regulation
9 - regulating valve
15 - spanner
Z W - cold water inlet
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:
- set the hot water tap at maximum flow,
- insert the spanner [15] into the regulation valve [9],
- set optimum flow (check if the temperature is comfortable for you) using
the spanner
- take the spanner [15] out of the regulation valve [9],
- close water flow using the tap.
The reccommended maintenance
needs to be repeated each time
after a decay of water.
If the water installation is not
vented the appliance may be
damaged.
1. Cut off electric supply.
2. Open the hot water tap to vent the installation (15-30 seconds).
3. Switch power supply on.

Chart 6 Characteristics
The appliance has a differential pressure switch [2] (picture 8). It switches
heating when there is a proper water flow through the heater.
There are two indicators (LEDs) on the case:
- green - power supply,
- red - heating.
6
The characteristics (picture 6) shows dependence between temperature
rise and flow rate per minute.
1. Cut off water and electric supplies.
2. Undo the fittings on the inlet pipe [7].
3. Take the filter out [12] of the fittings at the cold water inlet.
4. Clean the filter [12].
5. Install the filter [12] in the former position.
6. Connect cold water supply pipe [ZW] with the inlet pipe [7].
7. Open cold water pipe on water supply - check connections for le-
aks.
8. Vent the installation and the heater according to START-UP instruc-
tions.

We recommend always cleaning
the filter after any repairs to the
water installation or if there are
any impurities in the water, or
as a part of its regular annual
service check.
To ensure the long and faultless work of this appliance, you should clean the filter [12] from time to time. To
clean it, do the following:
Use the attached spray-head to
raise the comfort of use.

This heater has an overheating
protection:
- its over-temperature cut-out goes
off (shuts off power supply) when
the temperature in the heating
box [1] goes over 95oC. Once the
cut-out gets off, further operation
is not possible.

Faults If you notice any of the following signs of improper work, follow the instructions below:
- no or insufficient heating - a failure of the power supplies (for instance a fuse)
- rate of flow through the heater is too small (the filter might be blocked
with impurities or the flow regulating valve is set improperly)
- no bridge M1 (picture 4a, 4b), in case the heater works on one phase.
- the light indicators on the case
are off
- a fault in the power supplies (for instance a fuse)
