• If just the cold-water system is being used, without water heater, the heater tank is also filled up with
water. To avoid damage through frost, water must be drained by means of the drain valve, even if the
heater has not been used. As an alternative, two shut-off valves, resistant to hot water, can be fitted in
front of the cold and hot water connection.
Pressure and Temperature Relief Valve (P&T safety valve)
•
Risk of scalding injury from hot water and/or tampering with the P&T safety valve!
•
Do not actuate the P&T safety valve as long as the appliance is still hot.
•
Do not place a plug or reducing coupling in the discharge pipe (Fig. 2a - 4b) of the P&T safety valve.
•
Do not operate the water heater without a functioning P&T safety valve - this could cause an explosion.
The P&T safety valve (4) is a safety component and must not be removed for any reason other than replacement.
The P&T safety valve is not serviceable; if defective it must be replaced (failure to reuse an old P&T safety valve).
It must be replaced by a certified service technician.
Tampering with the P&T safety valve will void the warranty.
