TO FILL AND TURN ON THE WATER HEATER 
The power supply to the solar storage tank and solar control unit must not be 
switched on until the water heater is filled with water and a satisfactory megger 
reading is obtained. 
 

Open all of the hot water taps in the house (don’t forget the shower). Open the 
cold water isolation valve fully to the water heater. Air will be forced out of the 
taps. As water flows freely from each tap, close it. Check the piping for leaks.

· 

Bleed the solar collectors (refer to “Bleeding the Solar Collectors” on page 34). 

Switch on the electrical supply at the isolating switch to the solar storage tank. 

Plug in the solar control unit and switch the power on. 

 
Explain to the householder the functions and operation of the solar water heater. 
 
 
BLEEDING THE SOLAR COLLECTORS 
Upon completion of the installation, it is necessary to purge the air from the 
collector circuit. To purge air from the collector circuit: 
 

· 

Ensure the solar storage tank is full of 
water and all of the hot taps are turned 
off. 

· 

Using a flat blade screwdriver, open 
the bleed valve fitted adjacent to the 
5 way tee at the cold water inlet of the 
water heater (see diagram). 

· 

The mains pressure will force water to 
flow from the tank and through the 
pipe work, forcing air from the collector 
circuit through the bleed valve. This is 
evidenced by spurting of water from 
the drain line connected to the bleed 
valve. 

Warning: Exercise caution, as water may be at a very high temperature. 

· 

Close the bleed valve when water runs freely from the drain line.
