Review these instructions before beginning installation. Be sure that installation
conforms to all plumbing, electrical and other applicable codes.

When installation is complete, ensure these instructions are left in the plastic bag
provided inside the installed unit for future reference.

Service to be performed by authorized service personnel only .

NOTE: It is common practice to ground electrical hardware such as telephones, computers and other devices

to available water lines. This can, however , cause electrical feedback in the plumbing circuit, which
results in an “electrolysis” effect occurring in the fountain. This may result in water which has a metallic
taste to it or has a noticeable increase in the metallic content of the water .

When inspecting plumbing circuit, remember the line may be grounded some distance from the
installation, and may occur outside the building or area in which the unit is being installed.

This condition can be avoided (in most cases) by using recommended materials during installation. Any
drain fittings provided by the installer should be made of plastic which will electronically isolate the
fountain from the remainder of the building’s plumbing circuits.

1. Install chiller: Remove front panel of chiller. Remove

and discard cardboard inner pack from between
compressor and side panel. Slide chiller onto the

shelf and position it to the left as per dimensions in
Figure 1.

Note: Building construction must allow for
adequate air flow on both sides, top and
back of chiller. A minimum of 4” (102mm) on
both sides and top is required. See chiller
installation for additional instructions.

2. Make water supply connections. Install a shut-off valve
and union connection to building water supply (valve and
union not provided). Turn on water supply and flush the
line thoroughly.

3. ERPB Models: Make connection between remote chiller
and building supply line. Inlet port is marked on the chiller
(1/4” O.D. copper tube). Bend the copper tube (provided)
at an appropriate length from chiller to opening in frame.
Install the in-line strainer (provided with chiller) by pushing
it until it reaches a positive stop, approximately 3/4” (19mm)
on the marked chiller inlet port. Connect building supply
line to strainer. (See Figure 3)

Caution: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.

4. LRPB Models: Mount filter head assembly to side of
chiller (See Figure 4). Make connections between filter
and building supply line (3/8” O.D. tube not porvided).
Inlet port is marked on the chiller (1/4” O. D. copper tube).
Install a 1/4” x 1/4” union (provided) on the marked chiller
inlet port. Insert the 1/4” poly tubing (provided) into the
fitting on filter and connect the union to the chiller.
(See Figure 4)

Caution: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.

5. Hang the upper panel on the mounting frame hanger. Be
sure that the panel is engaged with hanger at the top of
frame before releasing it. Align holes in the panel with holes
in the mounting frame. Install two (2) #10-24 x 5/8” (16mm)

29, 30, 31, 32

screws (Item 29 - Figure 5) in holes and tighten securely.

6. Install the fountain. Remove the screw (Item 30) from cover
plate and slide cover plate (Item 14) toward basin. Mount the
fountain to the upper panel and frame with (4) 5/16” x 1”
(25mm) bolts (Item 33), brackets (Item 36) and nuts
(Item 35) provided. Tighten securely. Brackets (Item 36)

must be installed as shown to properly support
fountains. (See Figure 6)

7. Attach waste tube (1-1/4” O.D.) to 1-1/4” O.D. slip
trap (provided by others).

8. ERPB Models: Make connections between remote chiller
outlet tube and fountain. Outlet port is marked on the chiller
(1/4” O.D. copper tube). Install a 1/4” x 1/4” tee (provided)
on the marked chiller outlet port. Insert the 1/4” poly tubing
coming from the fountain into the union. Turn on the water
supply and check for leaks.

CAUTION:
into the strainer as damage to
o-rings may result.

LRPB Models: Make connections between remote chiller
outlet tube and fountain. Outlet port is marked on the
chiller (1/4” O.D. copper tube). Install a 1/4” x 1/4” tee
(provided) on the marked chiller outlet port. Insert the 1/4”
poly tubing coming from the fountain into the union.

CAUTION: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.

9. These products are designed to operate on 20-105
PSIG supply line pressure. If inlet pressure is above
105 PSIG, a pressure regulator must be installed in
the supply line.

CAUTION: Any damage caused by connecting
these products to a supply line with
pressure lower than 20 PSIG or
higher than 105 PSIG IS NOT
covered under warranty.

DO NOT SOLDER tubes inserted

10. Make electrical connections to the chiller. See
chiller instructions.

11. Check stream height from bubbler. Stream height is
factory set at 35 PSI. If supply pressure varies greatly from
this, remove push button (Item 17 - Figure 11) and adjust
the screw on the regulator (Item 19 - Figure 11). To remove
push button, remove set screw from bottom of sleeve
(Item 33). Insert a small punch in screw hole and push up
while grasping the push buttom and pull forward removing
the push button. Clockwise adjustment will raise stream height
and counterclockwise movement will lower stream height. For
best adjustment stream should hit basin approximately 6-1/2”
from the bubbler. Reassemble push button by pushing in on
button until the push button catches in the sleeve. Reinstall

the setscrew (Item 33) in the sleeve (Item 15).

12. Mount lower panel. Loosen the three (3) #10-24 x 5/8”
(16mm) screws (Item 29 - Figure 6) at frame bottom lip. Slide
upper tongue of lower panel under lower edge of already
installed upper panel. Tighten previously loosened screws

securely. (See Figure 7)
