INSTALLER
NOTE: It is common practice to ground electrical hardware such as telephones, computers and other devices to
availablewater lines.This can,however, cause electrical feedback inthe plumbing circuit, which resultsin
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
drainfittingsprovidedbytheinstallershould be made of plastic which will electronically isolate thefountain
fromtheremainderofthebuilding’splumbingcircuits.

1. Install chiller: Remove front panel of chiller. 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. Attach solenoid valve assembly to the underside of
cross member of mounting frame on electronic
sensor unit. (See Fig. 7).
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
(See Figs. 3) (Refer to Fig. 13 on page 7 for details on
assembling quick connect fittings). Attach an unplated and
deburred copper water inlet line and a service stop (not
provided) to the chiller. Turn on the water supply and flush
the line thoroughly.
Caution: DO NOT SOLDER tubes inserted
into the strainer as damage to
o-rings may result.
4. Make connection between remote chiller outlet tube
and solenoid valve assembly. Outlet port is marked on
the chiller (1/4” O.D. copper tube). Install a 1/4” tee
(provided) on the marked chiller outlet port. Insert one end of
1/4” poly tubing into the tee and the other end into the
straight fitting on the solenoid valve assy. (See Fig. 3)
5. Hang the upper panel on the mounting frame hanger. Be
sure that the panel is engaged with hanger at the top of
frame before releasing it. Align holes in the panel with holes
in the mounting frame. Install two (2) #10-24 x 5/8” (16mm)
screws (Item 27 - Figure 4) in holes and tighten securely.
6. Install the fountain. Remove the screw (Item 28) from cover
plate (Item 12) and slide cover plate toward basin. Mount the
fountain to the upper panel and frame with (4) 5/16” x 1”
(25mm) long bolts (Item 30), bracket (Item 34) and nuts
(Item 33) provided. Tighten securely. Brackets (Item 34)
must be installed as shown to properly support
fountain. (See Fig. 5)

7. Attach waste tube (1-1/4” O.D.) to 1-1/4” O.D. slip
trap (provided by others).
8. Connect the fountain drain waste tube to the building
sanitary sewer system. Connection should be made in
compliance with local plumbing code requirements. (Note:
Plumbing trap is not included with the fountain).
9. Make connection between solenoid valve assembly
and fountain(s). Insert the 1/4” poly tubing coming from the
fountain with sensor into the solenoid valve. Insert the 1/4”
poly tubing coming from the fountain with push button into the
tee (See Fig. 3).
10. Connect power cord of sensor to solenoid valve
assembly by running it through the back panel and
connecting it to terminal as shown in Fig. 8.
11. Turn on water supply and check for leaks. Release air
from tank by interrupting infrared beam; a steady stream of
water assures all air is removed. The sensor has a 30 second
maximum ON time. It may be necessary to step away from
beam a few times to allow chiller tank to fill.
DO NOT SOLDER tubes while
inserted into the strainer as damage
to o-rings may result.
12. 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 byconnecting
these products to a supply line with
pressure lower than 20 PSIG or
higher than 105 PSIG IS NOT covered
under warranty.
13. Make electrical connections to the chiller. See chiller
instructions.
14. Check stream height from bubbler. Stream height is
factory set at 35-40 PSI. If supply pressure varies greatly from
this, please do the following. For Push Button units only,
remove push button (Item 14 - Figure 12) and adjust the
screw on the regulator (Item 16 - Figure 12). To remove push
button, remove set screw from bottom of
sleeve (Item 31). Insert a small punch in screw hole and
push up while grasping the push button and pull forward
removing the push button. Clockwise adjustment will raise
stream height and counterclockwise movement will lower
stream height. For best adjustment stream
should hit basin approximately 6-1/2” from the bubbler.
Reassemble push button by pushing in on button until the push
button catches in the sleeve. Reinstall the set
screw (Item 31) in the sleeve (Item 12).
For Electronic sensor units only, remove lower
panel (Item 26 - Fig. 4) and turn adjustment screw on the
regulator (Item 16 - Fig. 8). Clockwise adjustment will raise
stream height and counterclockwise movement will lower
stream height. For best adjustment stream should hit basin
approximately 6-1/2” from the bubbler.
15. Mount lower panel. Loosen the three (3) #10-24 x 5/8”
(16mm) screws (Item 27 - Figure 5) at frame bottom lip. Slide
upper tongue of lower panel (Item 26 - Figure 6) under lower
edge of already installed upper panel. Tighten previously
loosened screws securely. (See Figure 6)

InstallationPackage
The components for installation are packed in three
separate boxes, regardless of the type of unit being
installed. The boxes contain the following:
Box No. 1: Wall Frame(s)
Box No. 2: Remote Chiller, ECH8
Box No. 3: Fountain Arm and Panels
Additional materials, as noted in the Parts List, are also
shipped in these boxes.
1. Orifice Assy: Minerals deposits on orifice can cause water flow to
spurt or not regulate. Mineral deposits may be removed
from the 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
water flow according to instructions on page 4.
3. Sensor Control: The sensor has a 2 second delay time. If sensor
fails to operate valve mechanism or operates erratically, check
the following:
a) Ensure there are no obstructions within a 40 inch radius from
the front of fountain.
b) Check wire connections at the solenoid valve and at the sensor.
CAUTION: Make sure unit is unplugged before checking any
wiring.
c) Ensure proper operation of solenoid valve. If there is an audible
clicking sound yet no water flows, look for an obstruction in the
valve itself or elsewhere in the water supply line.
WARNING: Do not expose sensor to direct sunlight.
4. Sensor Range Adjustment: The electronic sensor used in this
fountain is factory pre-set for a "visual" range of 36 inches. If
actual range varies greatly from this, or a different setting is desired,
follow the range adjustment procedure below:
a) Remove front lens.
b) Locate range adjustment screw between the lenses of the
sensor, then with a small tip screwdriver, rotate the range adjust-
ing screw clockwise to increase range or counter-clockwise to
decrease range. 1/4 turn of screw is equal to approximately
12 - 18 inches of range.
CAUTION: Complete range of sensor (24 - 46 inches) is only one
turn of the adjusting screw.
c) Replace lens.
TROUBLESHOOTINGANDMAINTENANCE
CARE ANDCLEANING INSTRUCTIONS
DO NOT use abrasive or chemical cleaners to clean the sensor lens.
They may dull the luster and attack the plastic cover and chrome
finish of the fountain. Use ONLY soap and water, then wipe with
clean cloth or towel. When cleaning adjacent surfaces, the fountain
and the sensor lens should be protected from any splattering of
cleaners. Acid and cleaning fluids can discolor and damage chrome
plating and plastic sensor lens.
