SAFETY DEVICES

A. Safety Valve
In – built safety (pressure relief valve) is set to operate between 6.5 bar (95p.s.i.) and 7.5 bar (109 p.s.i.) Service the safety valve at least once in 6 months Racold service persons. Close inlet water supply. Remove dirt/scales from the water connection side. Push rubber disk gently to ensure it is not stuck. Do not tamper with the sealed screw otherwise pressure setting will get disturbed. Fix back after replacing old fibre washer. Check for any leakage before switching on electric supply

B. Thermal Cut-Out
Stem type non self-resetting Thermal Cut out set to operate at temperature below 96 °C and disconnects electrical supply for extra safely. Please contact only authorized service Personnel in such an event.

C. Thermostat
Stem type self-resetting; Automatic Resetting type, ON/OFF indication by red lamp.

Warning : Do not switch on if there is a possibility that the water in the heater is frozen

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

ELECTRIC WATER HEATER INSTALLATION GUIDELINE FOR PLUMBERS

• Read Instruction Manual carefully and follow installation instructions.

• Safety valve are pre-set for certain working pressure. Under any circumstances do not tamper/over-tighten the safety valve.

• Continuous water dripping from Safety valve is an indication of excessive pressure at inlet of water heater compared to rated pressure. In that case install pressure reducing valve at the inlet.

• Check for leakage after installation, Plumbing & before switching ON the power supply.

• Ensure flow of water from outlet before connecting electric power supply to the appliance.

• Do not use excessive force while tightening inlet and outlet Couplings. This may cause serious damage to the water heater. Use Cross spanner for tightening

• Check Supply voltage at the place of installation 230V.

• Ensure proper earthing of electrical connection.

• No extension cords to be used.

• Use only ISI marked electrical accessories of proper rating e.g. 3 pin Plug, Connection Boxes, Wires etc.

• In water heaters, check whether both blue and red lamps are glowing when the water heater is switched on.

• Ensure all couplings/Joints are leak proof.

• Check the water Heater operation for one complete cycle i.g one cycle of Thermostat operation. i.e Cut off and Cut-in.

TROUBLESHOOTING
