1. System Connection
1.2 Vertical Stand Models
The 20 & 30 gallon tanks are equipped with plastic
stand base and 1” connection. The 40 gallon tanks
are equipped with 11⁄4” connection and steel support
base.
2. Location
2.1 Proper Pressure Tank Location
The pressure Tank 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 be-
tween Pressure Tank and switch.
EXPLOSION HAZARD
When pressure tank has been in service and a
change in the 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 caus- ing 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.
3. Adjusting Pre-Charge Air Pressure, Prior to
Installation
Step 1. Remove protective air valve cap
Step 2. Check pre-charge pressure (pressure should
be + or -10% of the factory setting)
Step 3. Release or add air necessary to make the
pre-charge pressure 2 psig below the pressure switch
pump cut-in setting. (Example, if you have an 20
Gal Tank with a pre-charge of 30 psig, and you have
a pressure switch setting of 30/50 psig, adjust pre-
charge of your tank from 30 psig to 28 psig.)
Step 4. Replace protective air valve cap.
EXPLOSION HAZARD
Failure to follow these instructions can cause a rup-
ture or explosion possibly causing serious or fatal
injury, ooding, and / or property damage.
4. System Connection
1. Locate the Pressure Tank in the nal desired
location
2. Level as necessary
3. To eliminate friction loss, do not reduce the pipe
size from the pump to the Pressure Tank.
5. Start Up
5.1 Fine Tuning Procedures
Many times the actual pressure switch will vary from
the standard pressure range indicated. These varia-
tions could cause a momentary lag of water delivery,
as the pressure switch is not “tuned to the tank pre-
charge pressure”.
