INSTALLATION
WARNING – To
prevent electri-
cal shock or
equipment dam-
age, power must
be off during
installation or
servicing of the
control. To prevent serious burns, the boiler
should be thoroughly cooled before
installing or servicing control. Only qualified
personnel may install or service the control
in accordance with local codes and ordi-
nances. Read instructions completely 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 enter-
ing the feed valve during or any time after installation. The feeder
should be installed with non-ferrous plumbing materials only to pre-
vent rust from contaminating the valve. Apply pipe compound spar-
ingly. 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 addition-
al information.
