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.
