4.14 Mounting the closed loop expansion tank & safety valve
The location for the mounting of the closed loop expansion tank and safety valve
(pressure) is shown in Figure 4.1a.
CAUTION
Do not add any heat transfer fluid in the expansion tank. The expansion tank
should be empty when the closed loop is under cold conditions.
4.15 Electrical connection of the electric heater
The connection of the electric heater of the storage tank with the main power supply
source of the house should be done by a licensed electrician and according to the
regulations in force.
A separate electric cable and circuit breaker should be used to provide power to
the electric heater. It is recommended that the cable is inside of an appropriate
protective pipe.
For the connection of the power cable you should first remove the cover of the flange of
the hot water storage tank, with the electric heater, the thermostat and the anode.
The cable to the electric heater should be connected according to the instructions shown
on the connecting terminals in the flange of the storage tank (see Figure 4.16).
The thermostat should be adjusted so that the electric heater does not raise the
water temperature more than the level of 55
o
C. Make sure that the tank is full with
water before you switch on the electric heater for checking purposes.
