Installation
Connect system pipe to tank flange. Use plastic or
steel pipe as required. To prevent leaks, use PTFE
pipe thread sealant tape on male threads of all
threaded connections to tank.
NOTICE: To be sure that joint is not cross-
threaded and that threads are clean, always make
connections by hand (without sealer) first. After
making sure that threads are clean, remove pipe,
add PTFE pipe thread sealant tape and remake
connection. Tighten by hand first; finish with pipe
wrench for tight seal.
NOTICE: When replacing a standard tank in
a submersible pump system, raise pump and
discharge pipe far enough to remove bleeder
orifices in discharge pipe and plug tees. When
replacing a standard tank in a jet pump system,
remove Air Volume Control (AVC) and plug AVC
port in pump.
In areas where the temperature is high for long
periods of time, the tank pre-charge pressure may
increase. This may reduce the tank drawdown
(amount of water available per cycle). If this occurs,
reduce the pre-charge pressure to 2 PSI below the
pump cut-in setting of the pressure switch.
It is necessary to flush all air out of the piping
system and water reservoir portion of the pre-
charged tank. This is required on new installations,
pumps requiring re-priming and pumps that have
been disassembled for service. Do this as follows:
1. Open faucets furthest from tank and allow
pump to operate.
2. Air in the system will cause a sputtering flow;
allow faucets to run until you have a steady, air
free stream.
3. Open and close faucets repeatedly until you are
sure all air has been removed.
4. If stream does not become steady, air may be
leaking into the system; check for leaks in the
piping on the suction side of the pump.

TO CHECK TANK AIR CHARGE
If drawdown (amount of water available per cycle)
decreases significantly, check as follows:
1. To check air charge in tank, shut off electric
power to pump, open faucet near tank, and
drain completely.
2. At the air valve in top of tank, check air
pressure with a standard tire gauge. Air pressure
should be 2 PSI below pump pressure switch
cut-in setting.
3. If the air pressure is more than 2 PSI below the
cut-in setting, add air to the tank. Use an air
compressor or a portable air storage tank.
4. Use soap or liquid detergent to check for air
leaks around air valve. Continuous bubbling
indicates a leak. If necessary, install new core
in air valve. This is the same as those used for
automobile tubeless tires.
TO CHECK PUMP PRESSURE
SWITCH SETTING
1. To check pressure switch setting, disconnect
power to pump at supply panel (but be sure
to leave pressure switch connected to power
supply wires).
2. Remove pressure switch cover.
3. Open a faucet near tank.
4. Bleed pressure down until pressure switch
contacts close; immediately close faucet.
5. Check pressure at valve with standard tire gauge
or with pump pressure gauge (if supplied).
6. Pressure gauge should read 2 PSI below pump
cut-in setting (28 PSI for 30-50 switch, 18 PSI
for 20-40 switch, etc.) If not:
A. Adjust switch according to switch manufac-
turer's instructions.
