After connection open cold water supply valve (Figure 1, p. 11) in EWH (11), hot
water valve at EWH outlet (Figure 1, p.12) and hot water tap on mixer to ensure outflow
of air from the EWH. When the final EWH filling, cold water will continuously flow out of
mixer tap. Turn the hot water tap on the mixer off.
When connecting EWH in places not provided with water mains it is allowed to
supply water to EWH from auxiliary tank using pumping station, or from the tank placed
at a height of not less than 5 meters from the top of EWH.
Note: for ease of maintenance during EWH operation it is recommended to install
drain valve (Fig. 1, p.4) in accordance with Fig. 1 (for models not equipped with drainage
pipe (not in the scope of EWH supply)).
If water pressure in water supply exceeds 0.7 MPa, pressure relief valve shall be
installed at inlet, upstream of EWH (not in the scope of EWH supply) to reduce water
pressure to standard.
CONNECTION TO POWER SUPPLY
Prior to power activation make sure EWH is filled with water!
