INSTAllATIoN
a) pump location: The pump should be installed in a clean, dry and
ventilated location which provides adequate room for servicing
and protection from freezing temperatures. It should be bolted
to a good foundation, preferably concrete and provided with
adequate drainage. Locating the pump as close as possible to
the water source reduces the friction in the suction pipe and will
give maximum capacities.
b) Suction pipe: It is recommended that only new, clean 1-1/4 inch
pipe or hose be used. If the pump is installed any appreciable
distance away from the source of water, the suction pipe should
be increased to 1-1/2 inches. Horizontal lengths of pipe must
gradually slope upwards from the source of water to the pump to
avoid air pockets in the line. Thread compound should be used on
all pipe joints and connections should be thoroughly tightened. A
foot valve must be installed and its operation should be checked
since a leak will prevent proper operation of the system. Make
sure the foot valve is located so that it will be submerged at all
times. If a sandpoint or driven well is used, install a check valve
next to the pump suction instead of the foot valve (Fig. 2b). All
installations must have a foot valve or a check valve in the
suction pipe.
c) pump to Tank Fittings: The discharge pipe from the pump to
the tank should be as short and direct as possible and should
be the same size as that of the pump discharge tapping. A
check valve should never be installed between the pump and
the tank.
d) Service line: The service line should be connected as shown in
Fig. 2a, b, c or d. The size of the service line required is governed
entirely by the amount of water needed and the length of the pipe.
The pipe selected should be large enough so that the friction loss
(determined from Table 2, Friction Loss Chart) will never exceed
20 ft. (6m) head.
Adhere to the guidelines of national, state and local
plumbing codes when installing this product. Check with
the appropriate agencies or water system professional for
additional information.

All wiring, electrical connections, and system grounding must
comply with the National Electrical Code (NEC) and with any local
codes and ordinances. Employ a licensed electrician.

e) Wiring: An electrician should be employed to do the wiring and
connect the electrical service to the pump. The pressure switch
is wired to the motor at the factory and the voltage for which
the motor is wired is indicated by a sticker where applicable.
Make sure the motor is wired for the same voltage as the
power supply. Refer to the motor nameplate or inside terminal
cover for voltage changing instructions. The power lines should
be connected to the pressure switch terminals marked "line"
(Fig.1). It is recommended that a separate circuit be led from
the distribution panel to the pump unit. A ground fault interrupter
(GFI) protected circuit should be used for all electrical devices
operating near water. Install a proper fused disconnect switch
in the line and make certain the wiring is adequately sized and
well insulated. undersized wire between the motor and the
power source will adversely limit the starting and load
carrying abilities of the motor. Minimum wire sizes for motor
branch circuits are recommended (Table 1). For added safety,
the pump and motor should be grounded to the well casing or
the ground in the distribution panel.
f) pressure Gauge: If a pressure gauge is supplied with the pump
or if you wish to install a pressure gauge, it should be installed
into the 1/4" NPT hole on the front of the casing directly beside
the discharge opening.
g) Air Volume control: If no perma-pressure tank is used in a
pressure system, an air volume control must be used to maintain
an air cushion in the pressure tank. Refer to pressure tank owner's
manual for instructions.
h) pressure Relief Valve: A high pressure safety relief valve
is recommended to be installed at some point in the water
system. Ensure its location is near the discharge of the pump,
in an area with adequate drainage. Be sure to direct the valve
such that any water flow could not spray toward any electrical
devices.
