ELECTRICAL SUPPLY

 (FIG. 6)

100 litre direct Potterton Gold units are fitted with 

one 3kW immersion heater, all other direct mod-

els are fitted with two 3kW immersion heaters as 

standard. It is recommended that these should be 

wired via a suitable controller to BSEN 60730. 

The 

POTTERTON GOLD MUST be earthed.

 

All wiring to the unit must be installed in  accordance 

with the latest IEE Wiring Regulations and the circuit 

must be protected by a suitable fuse and double 

pole isolating switch with a contact separation of 

at least 3mm in both poles. The live and neutral 

connections are made directly onto the combined 

thermostat and thermal cut-out located under the 

terminal cover(s) mounted on the side of the unit. 

The earth connection should be made to the earth 

connection located to  the side of the immersion 

heater boss(es). The supply cable must be routed 

through the cable gland located on the unit casing 

beneath the terminal housing.

DO NOT

 operate the immersion heaters until the 

cylinder has been filled with water.

SAFETY

DISCONNECT  FROM  THE  MAINS  SUPPLY 

BEFORE REMOVING ANY COVERS.

Never attempt to replace the immersion heater(s) 

other than with the recommended Potterton Gold 

immersion heater(s).

DO NOT

 

BYPASS THE THERMAL CUT-OUT(S) 

IN  ANY  CIRCUMSTANCES

.  Ensure  the  two 

male spade terminations on the underside of the 

combined  thermostat  and  thermal  cut-out  are 

pushed firmly onto the corresponding termina

-

tions on the element plate assembly. 

In  case  of  difficulty  contact  service  support; 

contact  details  available  at  the  back  of  this 

booklet.
