Caution:
• Connect the water heater using independent sockets, do not use adapters. Use
multimeter to check whether the live line and neutral line are not reverse, to ensure
complete safety.
• Before installing the water heater, confirm that the power of water heater matches
electric meter capacity and supply wire.
• The water heater should be earthed reliably. It is prohibited to connect the earth wire
to neutral wire or tap water pipe.
Attention:
• Make sure a suitable sealing tape is used for all connections to prevent leakage.
• Discharge tube should be installed downwards without any loops, folds or knots.
Ensure that the free end of the Discharge tube is placed over a suitable drain and away
from the users.
• Discharge tube is provided to release the discharge from the water heater(through the
safety valve) in case excessive pressure is developed. The contents of the discharge
from the Safety valve may be hot and may cause burns to the users and damage
nearby objects if not properly routed to a drain.
• It is recommended to operate the discharge lever in the safety valve on a regular basis
to ensure that there are no blockages and also to remove any lime deposits that would
have been formed inside the water heater.
• Ensure that the water heater is in power OFF condition when the Discharge lever is
being operated. Ensure that the water is filled completely in the water heater before
switching it ON.
