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 pipe joints are not
cross-threaded and that all threads are clean,
always make connections by hand (without seal-
er) first. After making sure that threads are clean,
remove pipe, add PTFE pipe thread sealant tape
and remake connection. Tighten by hand first; fin-
ish with pipe wrench for tight seal.
If installing a nipple in the plastic tank flange, tighten
it hand tight plus 1-1/2 turns with a pipe wrench.
DO NOT OVERTIGHTEN!
NOTICE: When replacing a standard tank in a sub-
mersible pump system, raise pump and discharge
pipe far enough to remove bleeder orifices in dis-
charge pipe and plug tees. When replacing a stan-
dard 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 two PSI below
the pump cut-in setting of the pressure switch.
It is necessary to flush all air out of the piping sys-
tem and water reservoir portion of the pre-charged
tank. This is required on new installations, pumps
requiring repriming and pumps that have been dis-
assembled 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 that comes out of
tank per pump 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 pres-
sure with a standard tire gauge. Air pressure
should be 2 PSI (0.14 Bar) below pump pres-
sure switch cut-in setting.
3. If the air pressure is more than 2 PSI (0.14 Bar)
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 sup-
ply wires).
2. Remove pressure switch cover.
3. Open a faucet near tank.
4. Bleed pressure down until pressure switch con-
tacts 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 (0.14 Bar)
below pump cut-in setting (28 PSI (1.9 Bar) for
30-50 switch (2.1-3.5 Bar), 18 PSI (1.25 Bar) for
20-40 (1.4-2.8 Bar) switch, etc.) If not:
A. Adjust switch according to switch manufac-
turer's instructions.
B. Reconnect power supply to pump and pump
up pressure in system.
