INSTALLER
ERPB2-8C ERPB2-8RAC
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).

NOTICE:
This water cooler must be connected to the water supply using a dielectric coupling.
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 water chiller, 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 indicated below.

INSTALLATION
1. When mounting unit in an open area, to insure proper ventilation,
maintain a 4" (102mm) clearance from cabinet louvers on each side
of cooler . When mounting unit in a cavity or behind a wall maintain
minimum space of 4" (102mm) on each side, 4" (102mm) on the top
and a depth of 12" (305mm).
2. Water inlet is 1/4" (6 mm) O.D. tube. Contractor to supply the
connections as required.
3. Connecting lines to be of unplated copper, thoroughly flushed to
remove all foreign matter before being connected to cooler. If
flushing does not remove all particles, a water strainer should be
installed in supply line. This cooler is manufactured in such a manner
that it does not in any way cause taste, odor, color or sediment
problems.
4. Connect cooler to building supply line with a shut-off valve and
install the in-line strainer between the valve and cooler.
5. Electrical: Make sure power supply is identical in voltage, cycle,
and phase to that specified on cooler serial plate. Never wire
compressor directly to the power supply.
6. This chiller has been designed for use with potable water ONLY.

START-UP
1. Open supply line valve.
2. Purge air from all water lines by operating bubbler valve of
fountain to which cooler is connected. Steady stream assures all
air is removed.
3. Rotate fan to insure proper clearance and free fan action.
4. Connect to electrical power.
TROUBLE SHOOTING & MAINTENANCE
Temperature Control: Factory set at 50°F (± 5°) under normal
conditions. For colder water, adjust screw on item no. 12 in
clockwise direction.
Ventilation: Cabinet louvers and condenser fins should be
periodically cleaned with brush, air hose or vacuum cleaner.
Excess dirt or poor ventilation can cause no cold water and
compressor cycling on the compressor overload protector.
Lubrication: Motors are lifetime lubricated.
Actuation of Quick Connect Water Fittings: Cooler is provided
with lead-free connectors which utilize an o-ring seal. To remove
tubing from the fittings, relieve water pressure, push in on gray
