The system cannot absorb the water expansion in heating To avoid dripping install an expansion tank or connect the safety valve to a drain See the relevant section Dripping from water safety unit and Expansion tank GENERAL NOTES Leaks are generally seen at the bottom of the appliance Condensation Dripping can occur if the water in the tank is cold Always check for leaks with the water hot Water leaks Hot and cold water flexible connectors Check tightness and replace the gaskets Tighten down and check tightness Leaks from heating element Check tightness replace gasket and tighten securely Replace the heating element if faulty 7 9 General notes Always use tools that are appropriate for the intended purpose Always replace the gaskets and or the o rings ensuring the hydraulic sealing Only use genuine spare parts During reinstalling make sure that e the electric heating element is properly housed and the sealing gaskets are correctly installed e the safety and regulation devices thermostats are properly installed inside their housings e before reconnecting the equipment to the mains fill it referring to the appropriate section and check that there are no water leaks 17 Oversink and Undersink Water Heater 7 10 Spare parts Oversink Undersink wm 7 11 After sale service
4. The example below is for a G 2 temperature relief valve with discharge pipe D2 having 4 No 22mm elbows and length of 7m from the tundish to the point of discharge From Table1 Maximum resistance allowed for a straight length of 22mm copper discharge pipe D2 from a G Y temperature relief valves is 9 0m Subtract the resistance for 4 No 22mm elbows at 0 8m each 3 2m Therefore the maximum permitted length equates to 5 8m which is less than the length of 7m therefore calculated the next largest size Maximum resistance allowed for a straight length of 28mm copper discharge pipe D2 from a G Y temperature relief valve is 18m Subtract the resistance for 4 No 28mm elbows at 1 0m each 4m Therefore the maximum permitted length equates to 14m As the actual length is 7m a 28mm D2 copper pipe will be satisfactory 3 59 Where a single common discharged pipe serves more than one system it should be at least one pipe size larger than the largest individual discharge pipe D2 to be connected 3 60 The discharge pipe should not be connected to a soil discharge stack unless it can be demonstrated that the soil discharge stack is capable of safely withstanding temperatures of the water discharged in which case it should a Contain a mechanical seal not incorporating a water trap which allows water into the branch pipe without allowing foul air from the drain to be ventilated through the tundish Beaseparate branch pipe with no sanitary a
