Procedure of putting the heater into operation:
1. Check both water and electric installation; for combined tanks, check also the installation to the hot
water heating system. Check proper placement of thermostat sensors. The sensors in the thermowell
have to be inserted all the way.
2. Open the hot water valve on the combination faucet.
3. Open the cold water inlet valve to the tank.
4. Once water starts draining through the hot water valve, filling of the tank is completed, and the valve
can be closed.
5. In case of leakage (of flange lid), we recommend that the flange lid bolts are fastened.
6. Screw down the electric installation guard.
7. When heating utility water with heat energy from the hot water heating system, open the heating
water inlet and outlet valves, or de-aerate the exchanger.
8. When commencing operation, flush the heater until the cloudiness in the water is gone.
9. Make sure to fill in properly the warranty certificate.
PUTTING OUT OF SERVICE, DISCHARGE
If the hot water tank is put out of service or is not used for longer time, it has to be emptied
and disconnected from power supply at all poles. The switch for the supply lead or the fuse cut-
outs have to be shut off.
In locations that are permanently exposed to frost, hot water tank shall be emptied prior to the
beginning of the cold season, if the appliance is not used for several days, and if the power supply
is disconnected.
Drainage of utility water shall be performed after closing the shut-off valve in the cold water
supply piping (through the discharge valve for safety valve combination), and with simultaneous
opening of all hot water valves of connected fittings. Hot water may outflow during
the drainage! If there is a risk of frost it has to be considered that not only the water in the hot
water heater and in the hot water piping may get frozen but also the water in the entire cold
water supply piping. It is therefore advisable to drain all fittings and piping that carry water,
up to the part where the house water meter is installed (connection of the house to water main)
which is not jeopardized by frost. When the tank is to be used again, it has to be filled with water
and one needs to make sure that the water flowing out at the hot water valves did not contain
any bubbles.
INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE
During the heating process the water that increases its volume during the heating must drip off
the safety valve outlet (in non-pressurized connection this water drips off the combination
faucet valve). In full heating (about 75 °C) the volumetric water gain is approx. 3% of the tank
capacity. The function of the safety valve has to be checked regularly (based on the information
contained in the attached safety valve manual). In common operation, such a check needs to be
implemented at least once a month, and after each heater shutdown that exceeds 5 days.
