Installation
■
■
Refer to the hose kit installation detail on page 26 for an illustration of
a typical supply/return hose kit assembly.
■
■
Pipe joint compound or Teflon tape is not necessary when using
factory supplied hose kits.
Note:
When antifreeze is used, ensure that it is compatible with
Teflon tape and pipe joint compound that may have been applied to
other pipe fittings in the system.
■
■
Unpack and examine hose kit. Remove all shipping and/or packing
material such as rubber bands, plastic caps and Styrofoam. Hose kit
should contain two hoses, two ball valves with shut off, and two hose
adapters.
■
■
Locate the valves inside the unit cabinet marked “water in” and
“water out.” Attach the hoses to the water valve. Always use a back-
up wrench when tightening the hose to the valve.
■
■
If you remove the valves to attach the hoses, be sure the O-ring is in
the valve before attaching to the union in the cabinet.
Note:
The valve union is to be hand tight plus an additional quarter
turn. Always use a back-up wrench on the fittings being tightened.
■
■
Attach flex hoses. Let the universal ends of the hoses hang inside the
cabinet.
Note:
Be sure the valve handles and P/T ports are in a position
that enables them to be opened and closed and used for system
readings. Check the swivel ends of the hoses. Gaskets must be in the
hose for proper seal.
■
■
Slide the chassis part way into the cabinet. Match the “water in”
hose to the “water in” tube on the chassis and the “water out” hose
to the “water out” tube. Tighten the swivel connection, keeping the
copper tube parallel to the sides of the chassis and then tighten the
hose to the copper tube, making sure the hose hangs straight without
twisting or turning.
Note:
The copper union and the hose union are to
be hand tight plus an additional quarter turn. Always use a back-up
wrench on the fittings being tightened.
