CONNECTIONS – ELECTRICAL 

 

The power supply to the primary heating source and circulating pumps must not be switched on until 
the storage tank is filled with fluid

 and a satisfactory megger reading is obtained. 

 

No  electrical  connections  are  to  be  made  on  the  storage  tank,  except  if  a  remote  thermostat  or  electric 
heating unit bundle if fitted. All electrical work and permanent wiring must be carried out by a qualified person 
and  in  accordance  with  the  Wiring  Rules  AS/NZS 3000  and  all  local  codes  and  regulatory  authority 
requirements. 

REMOTE THERMOSTAT 

The storage tank is fitted with 4 x RP1/2 fittings which can be used to monitor system temperature. 
1 x thermostat well is supplied with the storage tank, located in the TPR valve box.

ELECTRIC HEATING UNIT BUNDLE 

The tanks can be fitted with an electric heating unit bundle. The 
heating unit bundle is supplied with a digital thermostat which 
can be adjusted to suit site specific requirements. Also included 
is all switch gear and over temperature energy cut out (ECO). 
 
The heating unit electrical connections are housed in an IP55 
enclosure and the bundle connects to the storage tank via a 16 
bolt flange and gasket.  
 
The elements are low watts density incoloy 800, designed to 
provide long service life. A variety of kW ratings are available. 
Note: not all element ratings suit all tank capacities. The 
elements can be fitted in the top flange for “in-tank” boosting of the solar heat store or located in the bottom 
flange of a tank w

hen connected as an “in series” solar booster or electric water heater. 

 
Refer to the heating unit manual for heating unit details and installation requirements.
