E. DOMESTIC WATER CONNECTIONS
The water connections must be installed in accor-
dance with all national and local plumbing codes, or
any prevailing standard.
UNIONS OR GALVANIZED STEEL FITTINGS ON
ADVANTAGEPLUS CONNECTIONS. The inlet and out-
let connections are 1" on the 55 gallon models and 1-
1/2" on the 80 and 119 gallon models. On the cold inlet,
install a 1" brass tee on the 55 gallon models, or a 1-1/2"
brass tee on the 80 and 119 gallon models. On the run
of the 1" brass tee install, with pipe sealant, compound a
1" brass drain cock or it's equivalent (not supplied). Into
the branch of the 1" or 1-1/2" brass tee install a copper
male adapter to match with the copper plumbing system.
For convenience, you may install a shut off valve and a
union in the cold inlet piping to ease servicing in the fu-
ture. If there is a back flow preventer, or any type of a
check valve in the system, then you must install an addi-
tional tee for a suitable potable thermal expansion tank.
(See section on Expansion Tank.) In the hot outlet con-
nection, (top left), install a suitable adapter to match the
copper tubing of the plumbing system. A thermal trap or
heat trap loop may be installed here to provide additional
energy savings and prevent thermal siphoning of domes-
tic hot water. If required, a domestic hot water temper-
ing/anti-scald valve should be installed into the hot water
line to prevent the maximum outlet water temperature
from exceeding 125°F (52°C) to prevent scald injury.
The booster heater is equipped with a circulating pump to provide the
minimum water flow in the booster and maintain a uniform water tem-
perature in the tank. Depending on the physical distance from the
booster to the dishwasher, and the length of time between washes, it
may be necessary to run an empty rack to purge the supply line of
water that has cooled below 180ºF (82ºC). For this reason it is best to
locate the booster as close as possible to the dishwasher. The circula-
tor is equipped with three speeds to increase flow rate and reduce

See the following drawing for a typical "Booster" installa-
tion. Please note that those items marked with an aster-
isk in the drawing are not included with the Booster kit,
but are items that should be installed in a typical dish-
washer package.
heat loss. Reference the "Distance" chart to determine the appropriate
circulator speed setting.
All piping should be installed with suitable pipe insulation to avoid tem-
perature loss on the re-circulation line. A minimum of 1" thick pipe in-
sulation is recommended. Under no circumstances should the the
booster be installed without a circulating pump.
