employs a single pump for both Hot water and Central heating
circuits, by allowing the flow to either or both circuits using
separate valves.
INSTALLATION AND CONNECTION SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED
PERSON AND IN ACCORDANCE
REGULATIONS. A CLASS 'A' SWITCH (HAVING CONTACT SEPARATION OF AT LEAST 3MM IN
ALL POLES) MUST BE INCORPORATED IN THE FIXED WIRING AS A MEANS OF DISCONNECTING
