5. 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, WX-302 and WX-350 have a 1 1/4" elbow.
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
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-202XL with a
precharge of 38 psig, and you have a
pressure switch setting of 30/50 psig,
adjust precharge of your WX-202XL
from 38 psig to 28 psig.)
Step 4. Replace protective air valve cap. Peel
off backing of label and apply over air
valve cap.

Explosion Hazard. Failure to follow

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 recharge
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
