DISCHARGE PIPE SIZES
1. If increasing discharge pipe size, install reducer in
pump discharge port. Do not increase pipe size by
stages.
2. When pump is set away from the points of water use,
discharge pipe size should be increased to reduce
pressure losses caused by friction.
• Up to 100 ft (30M) run: Same size as pump dis-
charge port.
• 100 ft. to 300 ft (30-91M) run: Increase one pipe
size.
• 300 ft. to 600 ft (91M-183M)run: Increase two
pipe sizes.
PRESSURE TANK INSTALLATION –
DEEP WELL
A pressure tank provides a reservoir of water under pres-
sure and maintains a cushion of air pressure to prevent
pipe hammering and possible damage to plumbing com-
ponents. When water is drawn off through house fixtures,
pressure in tank is lowered and pressure switch starts
pump.
STANDARD TANK CONNECTION (Figure 7)
With a standard tank - an air volume control (AVC) adds
air to the tank when needed.To connect AVC to pump,
thread a 1/8” compression fitting into tapped hole on
front of pump. Cut tubing to length to reach AVC; assem-
ble to fitting on pump and to AVC on tank. See installa-
tion instructions provided with tank and AVC for details.
PRECHARGED TANK CONNECTION
(Figure 8)
No AVC is necessary with a precharged tank. A
precharged tank contains a factory provided air charge.
IMPORTANT: Pump pressure switch is set for a 40-60 PSI
(275-414kPa) range and requires a tank pre-charge of 38
PSI (262 kPa) for proper operation. See tank owner’s
manual for air charge. An annual check on tank air
charge is recommended.
ELECTRICAL
Ground motor before
connecting to electrical
power supply.
Failure to ground motor
can cause severe or fatal
electrical shock hazard.
Do not ground to a gas
supply line.
To avoid dangerous or
fatal electrical shock,
turn OFF power to motor
before working on electrical
connections.
Supply voltage must be
within ±10% of name-
plate voltage. Incorrect voltage can cause fire or seri-
ously damage motor and voids warranty. If in doubt con-
sult a licensed electrician.
Use wire size specified in Wiring Chart. If possible,
connect pump to a separate branch circuit with no
other appliances on it.
