Page 24: Commissioning
COMMISSIONING The thermostat(s) on the immersion heater(s) should be adjusted to trip at 60-65°C. This is the ideal temperature to prolong element life in hard water areas. Scale on the sheath builds up more rapidly at temperatures above this causing the element to overheat and premature failure can occur. Higher temperatures without additional controls would result in scalding. - Page 25 10) Test the operation of the temperature & pressure relief and expansion valves by lifting/turning the manually operated test lever/cap and observing that water flows through freely and safely to waste; 11) Check that the discharge pipe is plumbed so that it falls continuously and that no taps, valves or other shut off devices are installed in the pipe;...
