INSTALLATION INSTRUCTIONS
1.
Install
remote 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 side of shelf. (See Figure 6)
NOTE:
Building construction must allow for adequate air flow on both sides, top, and back of chiller. See chiller instructions 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 the water supply and flush the line thoroughly.
3.
ERPA 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 a 1/4" x 3/8" union
(provided) on the marked chiller inlet port. Connect building supply line to union. (See Figure 7)
LPTEA MODEL:
Mount filter head assembly to side of chiller (See Figure 9). Make connection between filter and building supply
line (3/8" O.D. tube not provided). Inlet port is marked on the chiller (1/4" O.D. copper tube). Install a 1/4" x 1/4" union (provided).
Bend the copper tube (provided) at an appropriate length from the filter and connect to the union on the chiller. (See Figure 8).
4.
Hang
the upper panel on the mounting frame hanger. Align holes in the panel with the holes in the mounting frame. Be sure that
panel is engaged with hanger at top of frame before releasing it.
5.
Install
the fountain. Remove access cover plate on underside of fountains and save the screws. Mount the fountain to the
upper panel and the wall frame with (4) 5/16" x 1 3/4" (44mm) long bolts and nuts (provided). Install spacers on bottom two bolts.
Tighten securely.
6.
Attach
waste tube (1 1/4" OD) to 1 1/4" OD slip trap (provided by others).
7.
ERPA MODELS:
Make connections between remote chiller outlet tube and fountain strainer. Outlet port is marked on the chiller
(3/8" O.D. copper tube). Install a 3/8" x 3/8" union (provided) on the marked chiller outlet port. Insert the 3/8" unplated copper
water line (provided) into the union and the inlet side of the strainer by pushing it in until it reachs a positive stop, approximately
3/4" (19mm). Connect 1/4" copper tubing coming from fountain to the strainer. Turn on water supply and check for leaks.
DO NOT
SOLDER TUBES INSERTED INTO THE STRAINER AS DAMAGE TO THE O-RINGS MAY RESULT.
(See Figure 6).
LPTEA MODEL:
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 3/8" union (provided) on the marked chiller outlet port. Insert the 3/8" unplated copper water line (provided)
into the union. Install a 1/4" x 3/8" union (provided) on the 3/8" copper tube and connect to the 1/4" copper tubing coming from the
fountain. Turn on water supply and check for leaks.
DO NOT SOLDER TUBES INSERTED INTO THE UNIONS AS DAMAGE TO
THE O-RINGS MAY RESULT.
(See Figure 8).
8.
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. Any damage caused by reason of connecting these products to supply line
pressures lower than 20 PSIG or higher than 105 PSIG is not covered by warranty.
9.
Make
electrical connections to the chiller. See chiller instructions.
10.
Check
stream height from bubbler. Stream height is factory set at 35 PSI. If supply pressure varies greatly from this, turn
adjustment screw on regulator (Item 12). Clockwise adjustment will raise stream height and counter-clockwise
will lower stream height. For best adjustment stream should hit basin approximately 6 1/2" from the bubbler.
11.
Mount
lower panel. Loosen the (2) #10-24 x 5/8" (16mm) screws at frame bottom lip. Slide upper tongue of lower panel under
lower edge of already installed upper panel. Tighten previously loosened screws securely.
12.
Replace
bottom access panel to fountain basin using screws provided. Tighten securely.
TROUBLE SHOOTING AND MAINTENANCE
1.
Orifice Assy:
Mineral deposits on orifice can cause water flow to spurt or not regulate. Mineral deposits may be removed
from orifice with a small round file not over 1/8" diameter or a small diameter wire.
CAUTION:
Do not file or cut orifice materials.
2.
Stream Regulator:
If orifice is free of material deposits, regulate flow according to instruction 10 stated above.
3.
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 fitting, relieve water pressure, push in on the gray collar while pulling on the tubing (See Fig. 2)
To insert tubing, push tube straight into the fitting until it reaches a positive stop, approximately 3/4".
4.
Caution:
Cleaning of Bronzetone Models requires special care. Outer surfaces must be cleaned with a mild detergent or
mixture of vinegar and water only, rinsed and wiped dry. Abrasive and acidic cleaners may eventually damage the
Bronzetone finish.
