Storage Tank:

The storage tank holds up to 3.2 gallons of product water. A bladder within the tank keeps water under pressure and

away from bare metal. The tank has an air pre-charge of 5-7 psi (without water) from the factory. See Warning about

tank pressure.

Storage Tank Preparation:

Locate the following:

plastic tank stand, tank valve, 1/4” male threads at top of tank, and the air pressure valve at bottom of tank

Step 1

Air pressure valve seats into tank stand when tank is in upright position. Place tank on stand.

Note:

Tank may be placed on its side, if necessary. Use tank stand to prevent rolling.

Step 2

Use Teflon tape (not included). Wrap 1/4” male threads on storage tank using clockwise motion for at least three

revolutions.
Step 3

Install tank valve on storage tank. Do this by hand tightening valve clockwise onto male threads of the storage tank.

Caution:

Do Not Overtighten.

KEEP TANK VALVE CLOSED. DO NOT OPEN TO ANY WATER UNTIL INSTRUCTED TO DO SO.

WARNING ABOUT TANK PRESSURE:

USE ACCURATE (0-20) GAUGE FOR LOWER READINGS TO MEASURE. IF NEEDED TO ADJUST, EMPTY TANK,

USE A SIMPLE BICYCLE OR SPORT BALL PUMP ONLY. DO NOT OVER-INFLATE TANK PRESSURE.

The tank should be 5-7 psi without water for proper operation. Pressure variances due to higher elevations may occur.

Under or over-inflation will prevent proper operation of system.
