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.
