Installation Instructions - Amtrol Well-X-Trol WX101 Installation Operation & Maintenance

6. INSTALLATION INSTRUCTIONS

System Connection
In-line Models WX-101, 102, 103, 105 and 200
In-line models WX-101, 102, 103 are conventionally installed
directly in the main water supply line with a 3/4" connection. For
model WX-200, a 1" fitting is used.
Vertical Stand Models WX-201 through WX-350
Vertical stand models WX-201 through WX-302 are equipped
with an elbow system connection. The WX-201, WX-202, WX-
202XL and the WX-203 have a 1" elbow. The WX-205, WX-250,
WX-251, WX-255, WX-252 and the WX-302 have a 1 1/4" elbow.
The WX-350 has a 1 1/4" tee connection for straight through
piping.
Location
Proper WELL-X-TROL Location
The Well-X-Trol should be installed as close as possible to the
pressure switch. This will reduce the adverse effects of added
friction loss and pressure switch bouncing, and the difference in
elevation between WELL-X-TROL and switch.
DANGER!
WHEN THE WELL-X-TROL HAS BEEN
IN SERVICE AND A CHANGE TO A HIGHER PRE-CHARGE
PRESSURE IS NECESSARY DUE TO A REQUIRED CHANGE
IN THE PRESSURE SWITCH SETTING, FAILURE TO
FOLLOW INSTRUCTIONS BELOW CAN CAUSE A RUPTURE
OR EXPLOSION, POSSIBLY CAUSING SERIOUS OR FATAL
PERSONAL INJURY, AND/OR PROPERTY DAMAGE.
• DO NOT ADJUST OR ADD PRESSURE IF THERE
HAS BEEN A LOSS OF AIR.
• DO NOT ADJUST THE PRE-CHARGE PRESSURE
IF THERE IS VISIBLE EXTERIOR CORROSION.
• DO NOT ADJUST THE PRE-CHARGE PRESSURE
IF THERE HAS BEEN A REDUCTION OF THE PUMP
CYCLE TIME OR THE PRE-CHARGE PRESSURE
COMPARED TO ITS INITIAL SETTING. THIS IS
BECAUSE REDUCTION IN PUMP CYCLE TIME
CAN RESULT FROM LOSS OF TANK AIR
PRESSURE WHICH IN TURN CAN MEAN THERE
MAY BE INTERNAL CORROSION AND ANY RE-
PRESSURIZATION OR ADDITIONAL PRESSURE
COULD RESULT IN RUPTURE OR EXPLOSION.
Adjusting Precharge
Prior to Installation
WELL-X-TROL tanks are shipped with a standard precharge of 18
psig for models WX-101 and WX-102, 38 psig for models WX-103
through WX-203, and 38 psig for models WX-205 through WX-350.
Step 1. Remove protective air valve cap
Step 2. Check precharge pressure (pressure should be + or -
10% of the factory setting)
Step 3. Release or add air as necessary to
make the precharge pressure 2 psig
below the pressure switch pump
cut-in setting. (Example, if you have
a WX-202-XL with a precharge of 38
psig, and you have a pressure
switch setting of 30/50 psig, adjust
precharge of your WX-202-XL from
38 psig to 28 psig.)
Step 4. Replace protective air valve cap.
Peel off backing of label and apply
over air valve cap.

injury, flooding, and / or property damage.
System Connection
1. Locate the WELL-X-TROL in the final desired location.
2. Level as necessary.
3. To eliminate friction loss, do not reduce the pipe size from
the pump to the WELL-X-TROL.
Start Up
Fine Tuning Procedures
Many times the actual pressure switch will vary from the standard
pressure range indicated. These variations could cause a
momentary lag of water delivery, as the pressure switch is not
"tuned to the Well-X-Trol precharge pressure".
1. Fill the system and WELL-X-TROL until pump cuts off.
2. Open one or more fixtures to drain the WELL-X-TROL.
3. If there is a momentary pause in the water flow from the
time the WELL-X-TROL is emptied and the pump starts,
adjust pump cut-in setting clockwise slightly (see figure 2).
4. Close fixtures and refill WELL-X-TROL to pump cut off.
Check time to fill.
5. Open fixtures and see if pause in water is eliminated. If not,
continue adjusting pressure switch.
Adjusting Precharge After Installation
Step 1. Drain tank of all water. Check precharge pressure in the
WELL-X-TROL Tank.
Step 2. Release or add air as necessary to make the precharge
pressure 2 psig below the pressure switch pump cut-in
setting.
All WELL-X-TROL "UnderGround Tanks" are designed for
direct burial and must be installed in the vertical position only.
To eliminate danger of freezing, tank should be buried below the
frost line.
The following steps should be taken when installing a
WELL-X-TROL "UnderGround Tanks":
1. Make sure that the tank will be buried below the frost line and
above the water table.
2. Remove plastic bag and check tank precharge. Factory
precharge is 38 psig. Replace air stem cap securely. Follow
adjusting precharge procedure.
3. Important: Install tank on firm rock-free earth.
4. The Water lines from the pump to the tank and switch location
should be the same size to prevent switch cycling.
5. Check the system for performance and inspect for leaks.
6. Important: Backfill hole with sand. Firmly tamp fill to prevent
settling. Failure to do so will shorten tank life.
7. Fill out pressure tank location sticker and affix to power panel
or other visible surface so tank can be easily located at a later
time.
