MOTORISED ZONE VALVES

V4043B/C/H

Installation

The V4043 Zone Valvemust be positioned where it cannot block any vent or cold feed when closed. It may be plumbed in at any angle but must not be mounted so that the powerhead is below the horizontal level of the pipework.

If fitted in a confined space, sufficient ventilation must be available to keep the valvewithin its ambient temperature range and access must be provided to remove the powerhead if necessary.
