APPLICATION
These valves consist of an actuator motor and valve
assembly for controlling the flow of hot and/or cold
water. The V8043A provides two-position, straight-
through control of supply water. The valves are
designed for use with fan coil and other units
requiring quiet, compact water valves. The V8043E
and V8043F also control supply water for baseboard
radiators and convectors.

INSTALLATION INSTRUCTIONS
Description
CAUTION
1. Disconnect power supply before connecting
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 disassembled,
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 thermostat.
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.
The valve location should be in an area where the
temperature does not exceed the maximum valve
operating temperature as shown in Specifications.
