PREPARATION
K. WATER PIPING
The domestic water connections must be installed in accordance to all local and national plumbing
codes, or any applicable standard which prevails. The inlet and outlet ports of the Phoenix are 1" on
55 gallon models. On the 80 and 119 gallon models, the inlet and outlet ports are 1 ½". On the cold
inlet, (bottom left), install a 1" brass tee on 55 gallon models, or a 1 ½" tee on 80 and 119 gallon mod-
els. On the run of the 1" brass tee, install with pipe sealant compound, a 1" brass drain cock or equiv-
alent. Into the branch of the 1" or a 1 ½" brass tee, install a copper male adapter to match your cop-
per plumbing system. For convenience, you may install a sweat shut off valve and a union in the cold
inlet piping to ease servicing in the future. If there is a back flow preventer, or any type of a no return
valve in the system, then you must install an additional tee here for a suitable potable hot water
expansion tank. In the hot outlet, (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 the thermal siphoning of domestic hot water.
L. AUXILIARY CONNECTIONS
The auxiliary connections are additional connections for an air handlers, plate exchangers or other
devices that supply hot water. These connections must be installed in accordance with all local and
national codes or any applicable standard that prevails. The auxiliary connections are 1" on all
Phoenix Models. Never use dielectric unions or galvanized steel fittings. Use only copper or brass
fittings. Teflon Sealant must be used on all connections. The top port is the supply outlet and the
bottom port is the return inlet.
n
WARNING
Never connect auxiliary connections to any system that uses glycol or other solutions
formulated for hydronic systems. These auxiliary connections are to be used only in a
potable water system. Failure to follow this warning could result in death or serious
injury.
