WARNING: ISOLATE MAINS SUPPLY BEFORE COMMENCING INSTALLATION 
 

INSTALLATION  AND  CONNECTION  SHOULD  ONLY  BE  CARRIED  OUT  BY  A  SUITABLY  QUALIFIED 
PERSON AND IN ACCORDANCE WITH THE CURRENT EDITION OF THE IEE WIRING REGULATIONS. 
 

A means of disconnection from the supply having at least 3mm contact separation in both poles 
must be incorporated in the fixed wiring. 
 

If in doubt consult a qualified electrician. 
 
 
Electric Water (Immersion) Element 
 

The Apollo GEM system uses a standard electric water element up to 3KW and will electronically 
regulate the power flowing into the heating element to give a controlled power input from 50W to 
3000W.
