1. PRODUCT ACCESSORIES

The product is packed together with service instructions and list of servicing organisations. For non-pressure
connection, no safety valve is used; the function of it is performed by a non-pressure combination faucet. The package
contains anchors and fasteners to mount the heater.

2. MESSAGE FOR CUSTOMERS

The electric heater is designed for preparation of hot water in households, cottages and various welfare facilities.

It allows installation of only one hot water consumption point. Its benefit is that it heats up water by power in an
unlimited all-day time range. The time of heating service water to the recommended temperature of 60°C is about 9 and
18 minutes, depending on the volume.
Environment Type:
It is recommended to use the product in an indoor environment with air temperatures from +2°C to 45°C and a
max. relative humidity of 80%.

3. TECHNICAL DESCRIPTION

The heater tank is plastic for non-pressure connection, the electric heating element is copper. The heater tank is

provided with a valuable polyurethane insulation, all is stored in an upper plastic container. Electric wiring is placed in
the bottom (upper) part of the heater, under the removable guard of the heater. Temperature of water can be set by a
thermostat within the range between 5°C and 75°C, using the symbols on the thermostat selector button (read more in
chapter 13). Cold water inflow is indicated with a blue ring, hot water outflow is indicated with a red ring.

5. OPERATING ACTIVITY

After the heater is connected to electric network, the heating element starts heating water. The element is turned
on and off by a thermostat.
Thermostat can be set as per your need within the range from 5°C to 75°C. We recommend setting service water
to max temperature of 55°C. This temperature ensures the optimal operation of the heater. After reaching the temperature
set, the thermostat switches off the electric circuit and discontinues water heating. The control light signals if the element
is in operation (light is on) or if it is off (the light goes out). In case of longer operation without using the heated volume
the thermostat has to be set to position 9°C (set the “snowflake” symbol on the thermostat button) to avoid its freezing.

6. WALL MOUNTING

Prior to mounting check the loading capacity of the wall. If needed, reinforce it. Mount the water heater in
vertical position only. The fastening screws must have guaranteed spacing of 140 mm. Mounting dimensions are specified
on Fig. 1.
