INSTALLATION, CARE & USE MANUAL
Page 1 (Rev. A - 6/2012)
To insure you install these models easily and correctly, PLEASE READ THESE
SIMPLE INSTRUCTIONS BEFORE STARTING THE INSTALLATION. CHECK
YOUR INSTALLATION FOR COMPLIANCE WITH PLUMBING, ELECTRICAL, AND
OTHER APPLICABLE CODES. After installation, leave these instructions with the
Fountain for future reference.
IMPOR TANT
THIS IS AN INDOOR APPLICATION ONLY.
ALL SERVICE TO BE PERFORMED BY AN
AUTHORIZED SERVICE PERSON.
IMPORTANT! INSTALLER PLEASE NOTE.
THE GROUNDING OF ELECTRICAL EQUIPMENT SUCH AS TELEPHONE, COMPUTERS, ETC. TO WATER LINES
IS A COMMON PROCEDURE. THIS GROUNDING MAY BE IN THE BUILDING OR MAY OCCUR AWAY FROM THE
BUILDING. THIS GROUNDING CAN CAUSE ELECTRICAL FEEDBACK INTO A FOUNTAIN, CREATING AN ELEC-
TROLYSIS WHICH CAUSES A METALLIC TASTE OR AN INCREASE IN THE METAL CONTENT OF THE WATER.
THIS CONDITION IS AVOIDABLE BY USING THE PROPER MATERIALS AS INDICATED. ANY DRAIN FITTINGS
PROVIDED BY THE INSTALLER SHOULD BE MADE OF PLASTIC TO ELECTRICALLY ISOLATE THE FOUNTAIN
FROM THE BUILDING PLUMBING SYSTEM. WE SUGGEST THAT THE BOTTLE FILLING STATION AND WATER
COOLER BE PROTECTED BY A GROUND FAULT CIRCUIT INTERRUPTER (GFCI).

HANGER BRACKETS & TRAP INSTALLATION
1) Remove hanger bracket fastened to back of cooler by removing one (1) screw. SEE FIGURE
3.
2) Mount the hanger bracket to the wall.
NOTE: Hanger Bracket MUST be supported securely. Add fixture support carrier if wall will not
provide adequate support. Anchor hanger securely to wall using all six (6) 1/4 in. dia. mounting
holes.
IMPORTANT:
5-7/8 in. (150mm) dimension from wall to centerline of trap must be maintained for proper fit.
INSTALLATION OF COOLER
3) Hang the cooler on the hanger bracket. Be certain the hanger bracket is engaged properly in
the slots on the cooler back as shown in FIGURE 3.
4) Remove the four (4) screws holding the lower front panel at the bottom of cooler. Remove the
front panel by pulling straight down and set aside, SEE FIG. 4, FIG.5.
WATER CONNECTION TO THE MAIN
5) Before making the water connection, make sure the mains water pressure is between 20 and
60 psi.
6) If the mains water pressure exceeds 60 psi, predispose a pressure reducer capable of reducing
the latter to the 20~60 psi.
7)Connection to the mains water supply is carried out with the aid of 1/4in PE tube
provided(dia 1/4").
8)The tube terminals (1/2”×1/4”fitting) must be connected to the mains supply by means of a
“water supply valve” G (not provided). SEE FIGURE 3.
FILLING INTERNAL ICE BANK
9) Remove the white plugs marked" Fill Ice Bank".
10) Connect water supply tube into the connector "Fill Ice Bank".
11)Open the "water supply valve" G, let the water enter the ice bank slowly and fill the ice bank;
once reach the right level, the exceeding water will run over the outlet of Overflow pipe, then close
"water supply valve" G. After that, connect water pipe into coupling-- "water in" with proper
pressure. SEE FIGURE 3.
Note: The connection of tank charge--"Fill Ice Bank" has to be disconnected.
12) Insert the white plug back to its original position(overflow).
DRAIN CONNECTION
The drain water is clean and it comes from the tray(basin) that collects any dripping during
dispensing.
Connect the drain pipe (O.D. 20mm) to drain with a drain-trap. If necessary, cut the pipe so as to
avoid narrowing or rising or backflow problems.
CLEANING
Warm, soapy water or mild household cleaning products can be used to clean the exterior panels
of the TB35 water coolers. Extra caution should be used to clean the mirror finished stainless steel
panels. They can be easily scratched and should only be cleaned with mild soap and water or
Windex glass cleaner and a clean, soft cloth. Use of harsh chemicals or petroleum based or abrasive
cleaners will void the Warranty.

disconnect drain, remove four screws from tabs along lower edge of upper shroud, unplug two wires
and water tube. SEE FIG.4, FIG.5 & FIG.6.
Bubbler
To remove the bubbler, first disconnect the power supply. The underside of the bubbler can be
reached through the access panel (Item 8) on the underside of the upper shroud (Item 14). Remove
the access panel by removing the retaining screw (item 24) . To remove the bubbler, loosen locknut
(Item 29) from the underside of the bubbler and remove the tubing from the quick connect fitting.
After servicing, replace the access panel and self-tapping screw. SEE FIG.7.
