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 ELECTROLYSIS 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.
To assure you install this model 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
inside the fountain for future reference.

1. Cut a rectangular wall opening 25-1/8” (638mm) W x 53-1/2” (1359mm) H, 11-3/8” (289mm) above the oor
line. Inside of this opening add (1) 1-1/2” (38mm) stud to create two openings: (1) 17-3/8” (441mm) W x 53-
1/2” (1359mm) H, and (1) 6-1/4” (159mm) W x 53-1/2” (1359mm) H. See Figure 3. Check local codes for
height requirement.
2. After opening is completed, reinforce opening on all sides so that it may adequately support water cooler
which weighs up to 150 lbs (68 kg) and also provides a means of securing Mounting Frame in place. NOTE:
Building construction must allow for adequate airow on both sides and top of chiller unit. 4” (102mm)
minimum required.
3. Install rough plumbing to fountain. See Figure 4 for location of supply water inlet to chiller and location of
waste water outlet.
4. Install wall frame assembly in wall opening with front edge of frame ush with nished wall face. Secure
frame through holes in top and sides to wall support members with 5/16” diameter fasteners (bolts or lag
screws) as required by wall constructions. (14) Bolts/screws required, not provided. CAUTION: DO NOT
USE LESS THAN REQUIRED QUANTITY AND SIZE (DIAMETER) OF FASTENERS.
5. Install electrical conduit. Figure 4 shows electrical conduit connection location.
6. Now you are ready to install fountain.

FILTER INSTALLATION INSTRUCTIONS
1. Remove front panel of chiller. Note: For color images please visit www.elkay.com.
2. Install 3/8" formed copper tube (item 2) to left side of lter head. Screw locknut hand-tight to seal. See Figures 5 and 18.
3. Mount lter head to chiller using (3) screws (provided). See Figure 6.
4. Push (1) piece of 3.5" long 1/4" O.D. poly tubing (item 24, provided) into tting on right side of lter head. See Figure 7.
See Figure 1 for operation of quick connect ttings.
5. Install 1/4" x 1/4" John Guest elbow (provided) to previously installed poly tubing. Install 3/8" x 1/4" John Guest elbow
(provided) to evaporator water inlet labeled "WATER IN". See Figure 8.
6. Connect 1/4" John Guest elbow to 3/8" x 1/4" John Guest elbow using (1) piece of 3.5" long 1/4" O.D. poly tubing (item
24, provided). Install lter cartridge to lter head. See Figure 9.

1. Familiarize yourself with the mounting frame which should already be in place in the wall. If not, refer to the mounting frame installation
instructions on page 2 before proceeding.
2. Determine location of rough plumbing. At this point, you should decide which style trap you plan to use. For easier installation, we
recommend the use of a swivel trap.
3. Install the basin (See Figure 10). Hold the basin ush against the wall, positioning the top edge just above the upper edge of the wall
frame. Then slide the basin down slowly until it engages the hanger bracket. Be sure the basin is rmly engaged before releasing it.
4. Finish securing the basin in place. Align the brackets (item 15) at the bottom of the basin with the bracket on the frame. Fasten the
brackets together using screws and speed nuts (provided, items 8, 28).
5. Install tailpiece assembly. Slide the slip nut and gasket from the trap onto the tailpiece. Insert the tailpiece assembly into the trap and
align its other end with the drain hole in the basin. Place rubber gasket between the tailpiece assembly and the basin, then screw in the
drain plug from above. Tighten the drain plug. Tighten slip nut and swivel joint. Snap the strainer plate into the drain plug.
6. Install a service stop (not provided) on the supply water inlet line. Turn on supply water and ush thoroughly.
7. Install remote chiller. Verify that lter has been installed inside chiller. Slide chiller onto shelf and center it within the shelf guides.
NOTE: Building construction must allow for adequate air ow on both sides, top, and back of chiller. See chiller instructions for additional
information.
8. Make connection between chiller inlet and building supply line (3/8” O.D. copper tube). DO NOT SOLDER TUBES
INSERTED INTO THE UNIONS AS DAMAGE TO THE O-RINGS MAY RESULT. (See Figure ).
9. Make connections between remote chiller and fountain. Outlet port is marked on the chiller (3/8” O.D. copper tube).
Install a 3/8” x 1/4” x 1/4” T-joint (provided, item 3) on the marked chiller outlet port. Insert 1/4” Poly in the T-joint and run
line to regulator.
10. Insert 1/4” elbow stem (item 31) into other end of T-joint (item 3). Insert 1/4” elbow stem (item 31) into cup ller (see
gure 13. Run 1/4” poly tubing (provided, 30”) between the two elbow stems. Turn on water supply, check for leaks, and
purge air from lines. DO NOT SOLDER TUBES INSERTED INTO THE UNIONS AS DAMAGE TO THE O-RINGS MAY
RESULT. (See Figure 11).
11. These products are designed to operate on 20-105 PSIG (0.14-0.72 MPa) supply line pressure. If inlet pressure is
above 105 PSIG (0.72 MPa), a pressure regulator must be installed in the supply line. Any damage caused by reason of
connecting these products to supply line pressures lower than 20 PSIG (0.14 MPa) or higher than 105 PSIG (0.72 MPa)
is not covered by warranty.
12. Make electrical connections to the chiller. See chiller instructions.
13. Check stream height from bubbler. Stream height is factory set at 35 PSI. If supply pressure varies greatly from
this, remove items 14 & 16 and adjust screw on regulator (item 27) (See Figure 16). Clockwise adjustment will raise
stream height and counter-clockwise adjustment will lower stream height. For best adjustment, stream should hit basin
approximately 6-1/2” from bubbler.
14. Install pushbutton to grill. See Figure 16. Hold grill and engage angle on top edge of grill with lower edge of basin. Swing
bottom of grill into place against the wall and secure grill with mounting screws (provided).

CUP DISPENSER INSTALLATION INSTRUCTIONS
1. The Cup Dispenser is designed to complement recessed drinking fountains. The fountain should
already be installed before beginning installation. If not, refer to page 2 for your model.
2. Check wall opening to see if provisions have been made to accept this cup dispenser. If they have
not, refer to page 2 for rough-in instructions. CAUTION: Wall construction must be framed to
support fountain and cup dispenser (approximately 150 lbs or 68 kg).
3. Orientate yourself to the conguration of the cup dispenser and remove waste bin. Note location
of mounting slots in the wall box portion of the cup dispenser (see Figure 7). The slots are for
afxing wallbox to building construction.
4. Put cup dispenser in wall opening. Determine shimming required to obtain a good alignment with
fountain. Open and close door to ensure proper operation. CAUTION: Do not “suspend” cup
dispenser via the mounting slots - be sure to shim along bottom edge to bear the weight of the cup
dispenser.
5. Secure cup dispenser in place. Use lag screws or bolts or bolts as required by wall construction.
6. Replace waste bin.

TROUBLE SHOOTING AND MAINTENANCE
Orice Assy: Mineral deposits on orice can cause water ow to spurt or not regulate. Mineral deposits may be removed
from the orice with a small round le not over 1/8” diameter or small diameter wire. CAUTION: DO NOT le or cut orice
material.
Stream Regulator: If orice is clean, regulate ow as in instructions. If replacement is necessary, see parts list for correct
regulator part number.
Actuation of Quick Connect Water Fittings: Cooler is provided with lead-free connectors which utilize an o-ring water seal.
To remove tubing from the tting, relieve water pressure, push in on the gray collar while pulling on the tubing. (See Fig.1) To
insert tubing, push tube straight into tting until it reaches a positive stop, approximately 3/4”.
