V4044C DIVERTER VALVE

INSTALLATION

V4044C incorporates a manual lever, the lever should normally be in ‘AUTO’ position, but can be moved to ‘MAN. OPEN’ position for system draindown and filling purposes only.

Before fitting the valve, read through the plumbing and wiring instructions.

This product MUST be installed by a competent person. The installation MUST conform to I.E.E. Regulations and with The Electricity at Work Regulations.

A Class ‘A’ switch (having contact separation of at least 3 mm in all poles) must be incorporated in the fixed wiring as a means of disconnecting the supply. The system must be appropriately fused.

PLUMBING

The valve MUST NOT be fitted on the return pipework under any circumstances. Flow from the boiler must be connected to port AB, the radiator circuit to port A and the hot water cylinder circuit port B.

The valve may be plumbed in at any angle, but must not be mounted so that the valve head is below the horizontal level of the pipework. In the unlikely event of a leak, a safety hazard could result.

Do not grip the valve head while making and tightening up plumbing connections. Attach a spanner (32 mm or 1 1/4” AF) onto the valve body at each port, whilst tightening up the nuts. Tighten compression nuts enough to make a watertight seal.

TAKE CARE NOT TO OVERTIGHTEN.

WIRING

The wiring diagram (Fig. 3) shows relevant connections to a Honeywell junction box (Part No. 42002116-001). Ensure that each numbered, lettered or coloured wire is connected to the correct terminal in the junction box. Make sure all connections are good and all terminal screws are firmly tightened.

Valve wiring configuration is:

Brown

= Motor open

Blue

= Neutral

Green/Yellow

= Earth

NOTES:

a.Wiring diagram shows connections to a programmer with separate control of heating and hot water.

b.If single channel time clock is used, connect switched live from time clock to terminal 4 or 6 at junction box, then link terminal 4 to terminal 6 with a link wire.

c.If the programmer or time clock have no ‘Hot water OFF’ terminal, then the time clock will need to be

replaced.
