INSTALLATION PROCEDURE
GENERAL NOTES:
The Model H1117LN.8 Water Cooler assembly requires installation of the mounting frame as
described in Steps 1 - 2, then mounting the fountain bowl assembly as described in Steps 3 - 6,
and finally completing chiller water and electrical connections and starting chiller per Steps 7 -
11. First check that all required parts are received.
Grounding may cause electrical feedback into the electric drinking fountain causing an
electrolysis, which creates a metallic taste or an increase in the metal content of the
water. This condition can be avoided by using dielectric couplings in the assembly. The
waste line, which is supplied by the installer, should also have a dielectric (plastic)
coupling to completely isolate the assembly from the building plumbing system.
NOTES:
1. For all plastic push-in type fitting connections, only connect NSF-61 copper or
plastic tubing. Stainless steel or glass tubing is not recommended. The
following assembly instructions must be followed to ensure a watertight
connection:
a. Cut tubing square and clean.
b. Mark from end of tube the length of insertion (See table below).
c. Push tube into the fitting until it bottoms out.
d. To remove, depress collet and pull tubing out.

2. If installing this unit with optional 1920HO (Hands-Off Model) or 1920:
a. Refer to the 1920 Series manual (supplied with model 1920HO or 1920) for
detailed installation & operation instructions.
b. It is recommended to use Model 6700 Mounting Plate (not supplied) with
Model BP32 Back Panel (standard Hi-Lo configuration - not supplied).
c. Reference page 10 of this document for 1920HO sensor or 1920 push button
height (Mounting hardware not supplied with Bottle Filler Water Dispenser).
d. Adjust nozzle flow rate using pressure regulator mounted inside bracket
(1920HO) or front adjust screw located on push button valve (1920).
e. Refer to the 1RKHO.H manual for Transformer and Sensor Setup
instructions (supplied with model 1920HO).
STEP 1:
Provide wall opening as detailed in Installation Drawing. Frame must be positioned
such that frame flanges overlap and butt against finished wall surface. Mounting
holes are provided for #6 sheet metal screws. After frame is positioned in wall, swing
chiller support tray into position (See Installation Drawing), align tray holes with holes
in frame and fasten with #10 sheet metal screws. Mounted frame must support 50-
pound chiller in addition to fountain weight and user generated forces.
