!
CAUTION:
Review these instructions before beginning installation. Be sure that installation
conforms to all plumbing, electrical and other applicable codes.
!WARNING:
When installation is complete, ensure these instructions are left in the plastic bag
provided inside the installed unit for future reference.
!
WARNING:
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 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.

underside of fountains and SAVE the screws. Mount
the fountains to the upper panel and frame with
(4) 5/16 x 3/4 (19mm) long bolts and nuts provided.
Tighten securely.
6. Remove elbow from end of p-trap and attach it to
drain tube. Re-attach elbow to p-trap and cut waste
tube to required length using plumbing hardware and
trap as a guide.
7. Make connection between remote chiller outlet tube
and fountain strainer. Insert the water inlet line into
inlet side of strainer by pushing it in until it reaches a
positive stop, approximately 3/4 (19mm). Turn on
water supply and check for leaks.
REQUIRED TOOLS AND MATERIALS
These tables show special tools and/or additional
materials (not provided) which are necessary to complete
installation of these units:

OVL-II ER-Q/SR-Q/SER-Q/ESR-Q 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 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.
3. Make water supply connections: Attach an unplated
copper water inlet line and a service stop (not
provided) to the chiller. Inlet port is marked on the
chiller (3/8 O.D. copper tube). Bend the copper tube
(provided) at an appropriate length from the chiller to
opening in frame. Install a 3/8 O.D. tube tee fitting
(provided) on the marked chiller outlet port. Turn on
the water supply and flush 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 top of frame before releasing it.
Note: With OVL-II SER-Q or OVL-II ESR-Q models, the
standard reach fountain must be mounted at the
upper position on panel.

CAUTION:
DO NOT SOLDER tubes into the
strainer as damage to o-rings may
result.
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.
!
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.
9. Make electrical connections to the chiller. See
chiller instructions.
10. Check stream height from bubbler. Stream height is
factory set at 45-50 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 20) by removing the screws holding assembly
together and adjust the screw on the regulator (Item
26  Figure 21). 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.

TROUBLESHOOTING & MAINTENANCE
Orifice Assembly: Mineral deposits on orifice can cause
water flow to spurt or not regulate. Mineral deposits may
be removed from the orifice by poking with a small round
file not over 1/8 diameter, or using a small diameter wire.
!
CAUTION:
DO NOT file or cut orifice
material.
Stream Regulator: If orifice is clean, regulate flow as in
Step 10 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 fitting, relieve water
pressure, push in on the gray collar while pulling on the
tubing. (See Figure 19) To insert tubing, push tube
straight into fitting until it reaches a positive stop (approxi-
mately 3/4).
