INSTALLATION & USE MANUAL
SWIRLFLO® Refrigerated fountains with FLEXI-GUARD® and ezH2O® Bottle Filler
EZWS-ERPBM28K INSTALLER
LZWS-LRPBM28K
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. 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. Caution: DO NOT SOLDER tubes
inserted into the strainer or filter head as damage to the o-rings may result.
2. Install mounting frame (instructions supplied with mounting frame.
3. (For LZWS-LRPBM28K) Install filter bracket on chiller (Fig. 9), then
install the filter head to the bracket, plumb from the filter outlet to the
chiller inlet with ¼” poly tubing and ¼ x ¼ union, install filter.
3a. (For EZWS-ERPBM28K) Install strainer on the input tube to the chiller
(Fig. 2).
4. Install chiller on shelf, install ¼ x ¼ x 3/8 Tee on chiller output tube.
Install supplied 4″ poly tubing and armaflex to the outlet of the previously
installed tee. Connect supplied ¼ x ¼ x ¼ tee to the 4″ poly tubing. With the
back panel standing close to the frame, connect 3/8″ poly tube to the bottle
filler.
Note: Building construction must allow for adequate air flow on both sides,
top & back of chiller. A minimum of 4″ (102 mm) on both sides & top is
required. See chiller installation for additional instructions.
5. Hang main panel on mounting frame hanger. Make sure the power cord, reset
switch wire & poly tube do not get pinched between the panel & mounting frame.
Ensure the panel en gages at the top. Align fountain holes with mounting frame
holes.
6. Remove protective coating from main panel.
7. Install reset switch for bottle filler (Fig. 4). Snap the switch into
position after locating wires through slot. Wrap up the excess cord.

8. Install fountains with (8) 5/16-18 HHMS & (8) 5/16-18 nuts (provided)
(Fig. 4). Connect the ¼” water lines from each fountain to the remaining
openings on the tee at the remote chiller (cut lines to fit as needed).
9. Attach waste tubes (1-1/4″ O.D.) to 1-1/4″ O.D. slip trap. Trap on the
bottle filler side must be 1-1/2″ O.D. (provided by others).
10. Make final water supply connections.
11. 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. (Caution: 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.)
12. Make electrical connections to the bottle filler and remote chiller. The
LCD Bottle counter should illuminate.
13. Verify proper dispensing from the bottle filler by placing a cup, hand or
any opaque object in front of sensor area and verify water dispenses. Note:
the first initial dispenses might have air in the line which may cause a
sputter. This will be eliminated once all air is purged from the line. A
steady stream of water assures all air is removed. The sensor has a 20 second
maxi mum ON time. It may be necessary to step away from the beam a few times
to purge all air. Check for leaks.
14. Check stream height from bubbler. Stream height is factory set for 35 PSI
supply. If supply pressure varies greatly from this, remove push button (Item
7 – Fig. 8) and adjust the screw on the regulator (Item 8 – Fig. 8). To remove
push but ton, remove setscrew from bottom of sleeve (Item 21). Insert a small
punch in screw hole and push up while grasping the push button and pull
forward removing the push button. Clock wise 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 the push button by pushing in on button until the push button
catches in the sleeve. Reinstall the setscrew (Item 21) in the sleeve (Item
6).
15. Install the cover plates.
16. Install the bottom panel, tighten screws (Fig. 4).
17. Optional: Mount optional panels. Slide tongue of panel under edge of
already installed panel. Tighten screws.

NOTE:
When installing replacement bubbler and pedestal (Fig. 6), tighten locknut
only to hold parts snug in position. Do Not overtighten.

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.
DO NOT file or cut orifice
material
Stream Regulator: If orifice is clean, regulate flow as in Step 14 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 Fig. 12) To insert tubing, push tube straight into fitting
until it reaches a positive stop (approximately 3/4″).
