Step 6:
Similarly complete the lower panel “s” clip installation. Check lower panel alignment
by partially installing side screws.
Step 7:
Unpack and remove chiller from carton. Remove front panel screws and panel. Do
not remove insulating putty and foam from copper tubes or Styrofoam insulation from
evaporator coil. Remove any inner packing, which may be around compressor. If
applicable, remove junction box cover and electrical knock out on lower right side of
housing. Install fittings (supplied) in chiller inlet and outlet tubes (See Installation
Drawing).
Step 8:
Thoroughly flush supply line to remove all foreign matter. Connect 1/2” IPS supply
screwdriver stop (not supplied) to stub-out in wall. Place chiller on chiller support tray
against right hand side, fully to rear, with condenser (open panel) side facing to front.
Install supply 3/8” O.D. tubing (not supplied) between screwdriver stop and chiller
inlet. (Cut tubing to proper length, and follow general notes for proper connection
procedures for push-in type fittings). Tubing insulation is not normally required on
inlet side of chiller. Install insulated tube between fountain and chiller outlet. Open
screwdriver stop wide open while checking for leaks at all connections. Also check
waste for leaks.
Step 9:
Verify that electrical power is off and power supply voltage, phase and cycle match
specifications printed on chiller label. In accordance with local codes, wire directly to
incoming lines at internal chiller junction box. Verify that all inner packing is removed
and hand rotate fan blade to verify free rotation. Reattach chiller front panel. Turn
power on and verify that chiller cycles off after water reaches proper temperature.
Finally check for leaks.
Step 10:
Install grille and tighten outer side screws. Verify there is chilled water out of bubbler.
