INSTALLATION
When Installing This Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable 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 connecting
wiring to prevent electrical shock or equipment
damage.
2. Normally it is not necessary to remove the
powerhead from the valve body during instal-
lation. 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 results in damage to the gear
train.
3. On 24V systems, never jumper the valve coil
terminals even temporarily. This can burn out
the heat anticipator in the thermostat.
IMPORTANT
Use this valve in hydronic heating systems that 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 deterio-
rate and eventually fail.
MOUNTING
The valve can be mounted in any position on a vertical
line. See Fig. 9. If the valve is mounted horizontally; the
powerhead must be even with or above the center line of
the piping. Make sure to leave enough room above the
powerhead to remove the cover for servicing.
