OVL-II Series - Dual Installation
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.
INSTALLER
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” e󰀨ect 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
ttings 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. Cut a rectangular wall opening 37-1/2” (953 mm) W
x 37-3/4” H (959 mm) and 4-1/2” (114 mm) above the
oor line (see Figure 7). The dimensions are required
to obtain proper rim and bubbler heights for compliance
with ANSI standard A117.1.
2. Reinforce the wall opening on all sides to adequately
support the water fountain. This reinforcement must
support up to 150 lbs. W load and provide a means for
securing the frame assembly in place.
NOTE: Building construction must allow for adequate
air ow on both sides and top of remote chiller
unit a minimum of 4” (102 mm) is required.
3. Install plumbing and electrical rough-ins. A junction
box for a (3) wire, 10 amp branch circuit is provided
on the inside of the chiller. (Standard 120 Volts, 60 Hz,
and single phase.)
4. Remove frames and related hardware from
packaging. Release the two shelf rods by cutting cable
ties. Attach the two frames together through the upright
supports with (4) 5/16” x 3/4” (19 mm) long bolts and
nuts (provided). Tighten securely.

building sanitary sewer system. Connection should
be made in compliance with local plumbing code
requirements. (Note: Plumbing trap is not included with
the fountain).
7. Make connection between remote chiller
outlet tube and fountain(s). Outlet port is marked
on the chiller (1/4” O.D. copper tube). Install a 1/4”
union/tee (provided) on the marked chiller outlet port.
Insert the 1/4” poly tubing coming from the fountain(s)
into the union tee. Turn on water supply and check for
leaks.

OVL-II ER/SR/SER/ESR INSTALLATION
1. Assemble and place frame in wall as shown on
preceding pages.
2. 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 within the
guides on the shelf.
NOTE: Building construction must allow for adequate air
ow 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.
3. Make water supply connections. Inlet port is marked
on the chiller (1/4” O.D. copper tube). Bend the copper
tube (provided) at an appropriate length from the chiller
to opening in frame. Install the in-line strainer (provided
with chiller) by pushing it in until it reaches a positive
stop, approximately 3/4” (19mm) on the marked chiller
inlet port. Attach an unplated and deburred copper
water inlet line and a service stop (not provided) to
the chiller. Turn on the water supply and ush the line
thoroughly.
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 topof frame before releasing it.
NOTE: With OVL-II SER or OVL-II ESR models, the
standard reach fountain must be mounted at the
upper position on panel.

DO NOT SOLDER tubes while
inserted into the strainer as
damage to o-rings may result.
8. These products are designed to operate on 20-105
PSI supply line pressure. If inlet pressure is above
105 PSI, a pressure regulator must be installed in the
supply line.
Any damage caused by connecting these products to
a supply line with pressure lower than 20 PSI or higher
than 105 PSI IS NOT covered under warranty.
9. Make electrical connections to the chiller. See
chiller instructions.
10. Check stream height from bubbler. Stream height
is factory set at 35-40 PSI. If supply pressure varies
greatly from this, remove items 2, 19, and 20 (push
arm and the bottom and the top actuator plates –
Figure 23) by removing the screws holding assembly
together and adjust the screw on the regulator (Item
14 – Figs. 24 & 25). Clockwise adjustment will raise
stream height and counterclockwise movement will
lower stream height. For best adjustment, stream
height should be approximately 1-1/2” (38mm) above
the bubbler guard. (See Figure 16).
11. Mount lower panel. Loosen the two (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.

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 ow 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-o󰀨 valve
and union connection to building water supply (valve and
union not provided). Turn on water supply and ush the
line thoroughly.
3. OVLERGRN: 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 19)
Caution: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.
4. OVLSERGRN & OVLESRGRN: Mount lter head
assembly to side of chiller (See Figure 20). Make
connections between lter 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) on the marked chiller
inlet port. Insert the 1/4” poly tubing (provided) into the
tting on lter and connect the union to the chiller.
(See Figure 20)
Caution: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.

TROUBLESHOOTING & MAINTENANCE
Orice Assembly: Mineral deposits on orice can cause
water ow to spurt or not regulate. Mineral deposits may be
removed from the orice by poking with a small round le
not over 1/8” diameter, or using a small diameter wire.
DO NOT le or cut orice material.
Stream Regulator: If orice is clean, regulate ow as in
Step 10, Page 9 of the installation 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 Figure 22) To insert tubing, push tube straight
into tting until it reaches a positive stop (approximately
3/4”).
To preserve the quality and keep
this AZTEC GOLD nish clean and
spot free, clean this surface with
only mild detergent or window
cleaner and polish with a soft
cloth. DO NOT use any abrasive
cleaners or harsh chemicals.
They WILL damage the nish!
