SAFETY DEVICES:

A. Multi functional Safety Valve:

(Non-Return Valve/Vacuum Release Valve/ Pressure Release Valve / Drain Valve) Nonreturn function will not allow the back flow of hot water from inlet. In-built multifunction safety valve (Pressure relief valve) is set to operate between 7.5 bar (109 p.s.i.) and 8.5 bar (123 p.s.i.)

Vacuum relief valve prevents the formation of vacuum inside the container. Drain lever (L) is provided to drain the water heater only in case of servicing. Check for any leakage before switching on electric supply. ln case of safety valve dripping during normal use, connect a discharge pipe (P) (as shown) for piping away the relieved water. In a continuously downward direction and in a frost-free environment. In case copper Pipe plumbing is done, additional 1/2 inch connector or adaptor to be connected to avoid safety valve damage by copper pipe. Contact nearest service centre for discharge pipe availability.

To avoid deposition of limes in the safety valve, please move the lever (L) up & down few times. This should be done at least once in a month. Minimum water head of 50cms. is required at inlet for water to enter inside the container.

Note: The rated pressure is developed inside the tank after healing at outlet pipe. It is recommended to maintain approximately 1.5 bar pressure at inlet pipe.

The safety valve (A) should be serviced at least once a month. Before servicing the safety valve, ensure that the water heater is switched off and water inside is not hot Connect the discharge pipe (P) in a downward sloping position to the safety valve at the discharge hole provided. The water may drip from the discharge pipe of the pressure relief device and that this pipe must be left open to the atmosphere. A discharge pipe connected to the pressure-relief device is to be installed in a continuously downward direction and in a frost-free environment.”

B. Thermostat:
Hi-tech adjustable thermostat with automatic ONOFF indication on display of control panel and variable setting of temperature. The temperature of water at which the thermostat In event of failure will cut off can be adjusted by setting the control panel to the desired temperature. This should be kept as low as possible, consistent with hot water demand. Scale formation in water heaters can be limited if due care is given to the temperature. The thermostat can be withdrawn without having to drain the water and in the installed position.

C. Thermal Cutout:
Hi-tech thermal cutout non-self resetting type set to disconnect electrical supply through two poles for extra safety. Please contact qualified service personnel in such an event.
