(2-6 ATM). Where sediment or mineral content in water is a problem, an inlet
filter is recommended.
PLUMBING CONNECTIONS: Inlet valve is 1/2 NPT (F). Waste trap outlet is
female 1-1/4″ NPT.
INSTALLATION PROCEDURE
GENERAL NOTES:
- For all plastic push-in type fitting connections, only connect NSF-61 copper or plastic tubing. Stainless steel or glass tubing is not recommended. The following assembly instructions must be followed to ensure a watertight connection:
a. Cut tubing square and clean.
b. Mark from end of tube the length of insertion (See table below).
c. Push tube into the fitting until it bottoms out.
d. To remove, depress collet and pull tubing out.
| Tube Sizes | O.D. Tolerance | Insertion Depth |
|---|---|---|
| 3/8” | ±.005” | 3/4” |
Refer to Installation Drawing for installation. Use pipe joint sealant on all
water connections.
STEP 1: Locate and mount the fountain on wall in desired location per
Installation Drawing shipped with fountain. Attach waste bend to underside of
fountain and mark center of tube on wall, drill 2-1/2″ hole through wall at
mark. Then locate and drill 1/2″ diameter hole and 1- 3/8″ diameter hole
through the wall (as shown on Installation Drawing).
STEP 2: Mount freeze-proof cabinet on backside of wall so that waste,
supply and operating holes in cabinet line up with holes drilled through wall.
Then cut and thread 1-1/4″ nipple long enough to allow the waste bend to enter
the nipple and the 1-1/4″ slipjoint nut and washer to be tightened fully on
the fountain side. The nipple must be long enough to be threaded into the
1-1/4″ NPT elbow in cabinet (see view A on Installation Drawing).
STEP 3: Snap in 1/8″ bushing (provided) before feeding the 1/8″ tubing
through the 1/8″ IPS pipe sleeve (not provided) (see view C on Installation
Drawing) then attach to the push button and secure with the compression nut
hand tight only. Bend the 3/8″ copper tubing (provided) into appropriate hole
and insert through the 1″ IPS pipe sleeve (not provided) from the cabinet side
(see view B on Installation Drawing). Connect tubing to drain valve fitting in
cabinet and measure, cut and connect tubing to bubbler. Be sure the tubing has
a uniform slope downward from the bubbler to the fitting on top of the drain
valve. Avoid low spots, which might collect water causing ice plugs in
freezing weather.
STEP 4: Flush the incoming water supply line before hook-up and install a
shut-off valve (not supplied).
STEP 5: Insert 1/2″ IPS pipe supply (not supplied) through side of box
and attach to ½” NPT elbow (supplied). Insert 1-1/4” IPS waste pipe (not
supplied) through the side of box and attach the 1-1/4” elbow of the trap
assembly.
STEP 6: Turn on the shut-off valve (not supplied) and check for leaks.
Push the operator button on and check for leaks. When the button is released
the control valve should turn off and the drain valve should open and allow
the 3/8″ bubbler line to drain into tailpiece above the trap.
STEP 7: When the fountain operates satisfactorily, install the cover on
the box with the louver openings facing down. Attach the bottom plate to the
fountain.
IMPORTANT: VALVE BOX MUST BE MOUNTED IN HEATED AREA PROTECTED FROM
FREEZING TEMPERATURES. PROVISIONS SHOULD BE MADE TO ALLOW ACCESS TO ACCESS
PANEL.
TROUBLESHOOTING
| PROBLEM | REPAIR CHECKLIST |
|---|---|
| 1. Bubbler Flow Control. | 1. Adjust pressure regulator: |
a. Loosen the locknut.
b. Rotate the knob clockwise to increase flow or counterclockwise to reduce f
low.
c. Tighten the locknut.
d. Repeat the above steps until the bubbler flow is correct.
e. Replace pressure regulator if necessary.
2. Insuf ficient bubbler f low| 2. a. Check that the shut-off valve (not
supplied) is wide open.
b. Verif y minimum 30 psi supply pressure.
c. Clean inlet strainer screen located in the valve body.
d. Adjust Pressure Regulator (Ref er to Step 1).
3. No flow| 3. a. Check f or leaks in the air tubing going f rom the push
button to the valve.
b. Make sure the air tubing compression nuts are hand tight.
c. Disconnect air tube f rom push button assembly. Blow into tube to verif y
valve f unction. Replace valve if necessary (Model 5881).
d. Disconnect air tube f rom push button. Place f inger over air outlet. Push
button to test diaphragm. Tighten diaphragm cap screws. Replace diaphragm
assembly if necessary (Model VRK2AV).
4. Continued insuf ficient or varied height of bubbler flow.| 4. a. Check f
or kinks in the tubing.
b. Replace pressure regulator if necessary.
5. Continuous bubbler f low.| 5. a. Ensure that push button is not
obstructed and springs back to normal position.
b. Remove f our screws which secure plastic diaphragm block to brass valve
body. Pull plastic and rubber diaphragm assembly out of valve body. Locate
tiny hole in rubber diaphragm just under lip of plastic part. Clean debris f
rom this hole. Inspect valve seat f or grooves. If seat is worn, replace with
stainless steel seat (newer models) or replace valve (older models, integral
brass seat).
c. If valve seat was OK and diaphragm holes were free from debris, inspect
rubber button located at center off loating steel disc in valve diaphragm
block assembly. If button is worn, turn disk over or replace disk (Model
VRK2AV).
d. If diaphragm and seats are in good condition, stretch spring slightly.
Spring is located behind f loating stainless-steel plate.
e. Ensure that air bleed port on valve plastic block assembly is not plugged.
6. Water leaking f rom valve box in wall.| 6. a. Check tubing connections f
or leaks.
b. The drain-back f reeze protection f eature drains through a 1”
air gap surrounded by plastic f unnel (splashguard). If drain is
plugged, water will spill out of f unnel. Unplug drain.
7. Fountain line f rom valve box to bubbler blocked with ice.| 7. a. Check
slope of tubing to bubbler, must slope downward f rom
bubbler to drain valve.
b. Clean or replace drain-back valve threaded into tee strapped
to plastic f unnel (Model 6518FRDV).
General Notes: Bef ore tightening nut and ferrule assembly, push tubing
into f itting until it bottoms out to ensure correct engagement with O-Ring.
