INSTALLATION
WARNING
–
To prevent electrical shock or
equipment damage, power must be off during
installation or servicing of the control. To pre-
vent serious burns, the boiler should be thor-
oughly cooled before installing or servicing
control. Only qualified personnel may install or
service the control in accordance with local
codes and ordinances. Read instructions com-
pletely before proceeding.
Step 1
Warning
Step 2
Plumbing
The feeder can be mounted on a horizontal or vertical cold water supply line.
It must be installed with a manual by-pass valve and unions (as shown
above) for future serviceability. Arrows on the valve indicate direction of
water flow. Do not install feeder on hot water supply.
IMPORTANT: It is important to prevent any contaminants from entering the
feed valve during or any time after installation. The feeder must be installed
with non-ferrous plumbing materials only to prevent rust from contaminating
the valve. Apply pipe compound sparingly. Remove and clean the feed valve
strainer after the first feed cycle to remove any contaminants that could have
been introduced during installation. See Service / Maintenance on page 4 for
additional information.
