Honeywell Home V4043 Installation Instructions Manual

V4043, V4044, V8043 and
V8044 Zone Valves

APPLICATION

These valves consist of an actuator motor and valve
assembly for controlling the flow of hot and/or cold
water. The V4043 and V8043 provide two-position,
straight-through control of supply water. The V4044
and V8044 provide two-position, diverting control of
supply water. The valves are designed for use with fan
coil and other units requiring quiet, compact water
valves. The V8043E and F also control supply water
for baseboard radiators and convectors. The V4043E
and V8043J provide straight-through control of
steam only. Models are available with 125 or 300 psi
operating pressure.

INSTALLATION

When Installing this Product...
1. Read these instructions carefully. Failure to fol-
low them could damage the product or cause a
hazardous condition.
2. Check the ratings given in the instructions and
on the product to make sure the product is suit-
able for your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
1. Disconnect power supply before connect-
ing wiring to prevent electrical shock of
equipment damage.
2. Normally it is not necessary to remove the
powerhead from the valve body during
installation. If the valve must be disas-
sembled, be certain that it is reassembled
with the water flow in the direction of the
arrow. Reversal of the powerhead will
result in damage to the gear train.
3. On 24V systems, never jumper the valve
coil terminals even temporarily. This may
burn out the heat anticipator in the ther-
mostat.
INSTALLATION INSTRUCTIONS
IMPORTANT
Use this valve in hydronic heating systems
which do not contain dissolved oxygen in the
system water. The dissolved oxygen, which is
found in systems that have a frequent source
of makeup water, causes the rubber plug
inside the valve to deteriorate and eventually
fail.

LOCATION

Install the valve in an area with adequate clearance
to:
— Move the manual opening lever on the side of
the powerhead.
— Remove the powerhead cover.
— Wire the powerhead.
— Replace the powerhead motor.

MOUNTING

The valve can be mounted in any position on a vertical
line. If the valve is mounted horizontally; the
powerhead must be even with or above the center line
of the piping. Make sure that enough room is
provided above the powerhead to remove the cover
for servicing.
