Water Connection :
The device is approved for heating water whose electrical resistivity is at
15 ° C ≤ 1300 Ωcm. The electrical resistance of the water , water distribution
can be obtained from the competent authorities.
Clean impurities from the system before connecting water supply to the
water inlet of the device. This could be achived through flowing water for a
while after connecting a hose to the water supply.
Do not use different sealing materials for sealing in any of the connections.
Connect cold water supply to the water inlet of the device (marked in blue)
and hot water line to the appliance water outlet (marked in red) with suitable
water pressure-resistant spiral connection hoses by using one piece of the
seal at each end.
Make sure that the connecting pipes are placed axially inside the sleeves.
Tighten well the capped nuts of sleeves while keeping it counter with a
proper monkey wrench.
Ensure that water goes into the device by opening the water valves and
control whether there are leaks in the connections or not.
