Remove QE1/QE2 from packing and prepare it for use on fully pumped or for gravity hot water systems. For gravity hot water systems no action is required.

For fully pumped systems the switch located at the rear of the “QE2” must be moved to the right- into the “fully pumped” position.

Installation INSTALLATION PROCEDURE

Remove QE1/QE2 from packing and prepare it for use on fully pumped or for gravity hot water systems. For gravity hot water systems no action is required.

For fully pumped systems the switchlocated at the rear of the “QE2” mustbe moved to the right-into the “fully pumped” position.

NB • Installation must be carried out by a qualified electrician and conform to current IEE Regulations. NB • Mains supply must be suitably fused (usually 3 amps) and provision made for Class A circuit disconnection.

NB • Installation must be carried out by a qualified electrician and conform to current IEE Regulations. NB • Mains supply must be suitably fused (usually 3 amps) and provision made for Class A circuit disconnection.

NB • Control is suitable for fixed wiring only.

NB • If the unit is to be surface wired:- Remove backplate by slackening fixing screw and separate the plate from the timeswitch- Remove the knock-out from the backplate and the timeswitch- Screw backplate to wall with counter sunk No. 8. Wood screws, using fixing holes provided.

NB • For socket box mounting:- Use the centre two holes and fit backplate to box using machine screws- To ensure clearance for the down flap, ensure that there is a minimum of 4 cm clearance under the unit when

mounted
