is unobstructed and connected to the floor drain.

Power Connection

All power connections should be done by an authorized installer.
Ensure the water heater is reliably grounded. The earth wire must
be longer than the current carrying conductors. The maximum
power of this water heater is 3000W, hence a single dedicated
power supply circuit is proposed. The core area of the electric
supply wire should not be less than 2.5 mm². Secure the wires with
the plate after connections are complete.

Water Filling

After all the pipes are connected, open the discharge valve of the
water heater and then the feed valve. Fill the water heater with
water and exhaust the air till a uniform water stream flows out of
the hot water outlet. This indicates that the water heater has been
filled up. Close the hot water discharge valve and check all
connections for any leakage. If leakage occurs, empty the water
tank, repair the leaked connection and then refill the heater with
water. Do not close the feeding valve during the filling of water.
