Wall Mounting - Cerbos BTO 5 IN/UP Bedienungs- Und Installationsanweisung

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 41°C (type BTO 5) and 35°C (type BTO 10). 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
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.
7. PLUMBING FIXTURE
The heater is designed for flow (non-pressurised) plumbing system. This system enables water withdrawal from
one point only. Connection has to be performed as indicated on the figure for connecting to water supply network.
For flow connection system you need to use a combination faucet designed to this purpose. Water inflow and
outflow is indicated
is indicated with blue, hot water outflow is indicated with red. Return valve has to be fixed on the inflow tube in
front of the combination faucet in order to avoid water outflow from the boiler if there is a lack of water within
the network.
If the water pressure in the water supply network exceeds 5 bars, a reduction valve must be installed in front of
the combination faucet.
When choosing a flow faucet pay special attention to the information provided by the manufacturer regarding
pressure reduction due to resistance that occurs when water passes through the combination faucet. If the drain
valve is fully opened, it must not exceed 0.2 bar. You are not allowed to fix any water driven device or a water
disperser on the
of the pressure in the heater boiler. Should you fail in adhering to these instructions, the heater may get damaged.
