Notes:
•
To ensure safe and effective performance, this water heater shall be installed, maintained and repaired strictly in
accordance with the appropriate and relevant requirements of SANS 10254.
•
For safe performance this water heater is fitted with a:
Thermostat
Non-self resetting thermal cut-out
Combination Temperature Pressure Relief (TPR) Valve (Safety Valve)
Pressure Control Valve and Expansion Control Valve (ECV) (unless the water supply pressure cannot exceed the
rated pressure of this water heater or its safety value whichever is lowest)
Heat exchange jacket (solar heater transfer fluid circuit) pressure relief valve (when operated with solar heating)
▪
80 kPa – without Over Temperature Protection (OTP) to the heat exchanger jacket vent port
▪
200 kPa – with Over Temperature Protection (OTP) to the heating fluid reservoir tank.
Warnings
This water heater MUST NOT BE OPERATED without each of these devices fitted and in working order.
The Temperature Pressure Relief Valve, Expansion Control Valve and their drain pipes must not be tampered with.
DO NOT seal or block the relief valve, control valve or drain pipe outlet.
Emergency Shut Down Procedure
If it is necessary to turn off the water heater:
•
Switch off the electrical supply at the isolating switch to the solar storage tank.
•
Close the cold water isolation valve at the inlet to the water heater.
•
Open a hot tap if it necessary to relieve the pressure in the water heater.
