ELECTROCUTION AND EXPLOSION HAZARD.

Before work is performed on the tank, turn off the power to the pump and release all water pressure in the tank and pumping system.

How a Well Tank Works

1. As the pump fills the tank with water, the air above the

diaphragm is compressed. This increases the pressure in the tank and causes the pressure switch to turn off the pump.

2. When water is used, it is drawn from the tank and the pressure

inside the tank decreases. The reduced pressure starts the pump and refills the tank.

The amount of water delivered between pump cycles is called drawdown. The larger the well tank, the greater the drawdown capacity, the less the pump needs to run. This saves energy and

money, and extends pump life. Larger tank sizes also increase the water storage volume to provide more consistent water pressure.

Installation of In-Line Turbulator

The In-Line Turbulator water circulation device is designed to circulate the water stored in your diaphragm well tank.

1. Inspect the In-Line Turbulator for any damage that may

have occurred during shipping. Insert the In-Line Turbulator (Diagram 1) into the system connection of the expansion tank. The Turbulator can only be inserted with the butt end out as the locking tabs prevent it from being installed backwards.

2. Palm press the In-Line Turbulator (Diagram 2) until the unit

locking tabs butt up against the system connection.

Pre Installation

The surface on which the Well-X-Trol is installed should be capable of supporting its operating weight (including the weight of water). 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 differences in elevation between Well-X-Trol and/or water supply main and switch.

Adjacent to pump: This is the location chosen most often. The Well-X-Trol tank can be used whether pumps are above or below the surface. In either case, it protects the pump by reducing surge, dampening pressure spikes, offering a point of pressure control, and providing minimum run time. This location also permits all equipment to be placed in an area that’s both serviceable and secure.

At the end of long pipe runs: The Well-X-Trol tank can be positioned at the end of a long run of pipe so it can provide rapid system response and adequate protection. When this location is chosen, the pressure switch should either be relocated with the Well-X-Trol tank or the setting should be adjusted to compensate for any line pressure drop.

DO NOT LOCATE IN AN AREA WHERE

LEAKAGE OF THE TANK OR CONNECTIONS COULD CAUSE PROPERTY DAMAGE TO THE AREA ADJACENT TO THE APPLIANCE OR TO LOWER FLOORS.

Locking Tabs

1. Remove protective air valve cap.

2. Check pre-charge pressure.

3. Release or add air as necessary to set the pre-charge

pressure 2 psig below the pressure switch pump cut-in setting. (Example, 38 psig precharge for a 40/60 pressure.)

4. Replace protective air valve cap.

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 Tank:

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.

Fine Tuning Procedures

1. Restore power and pressurize system until pump cuts off.

2. Open one or more fixtures to reduce pressure and initiate a

pump cycle.

3. Check operation. Make adjustments only when the tank is

empty of water and the system is off.

Figure 2

Pressure Adjustment:

• Clockwise to increase cut-out pressure.

• Counter-clockise to decrease cut-out pressure.

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 set the precharge pressure 2 psig below the pressure switch pump cut-in setting.

Maintenance

A licensed professional should check the complete system, including the Well-X-Trol, yearly and more frequently as the system ages.
