INSTALLATION
V4043H 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 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.
