MAKING THE ELECTRICAL CONNECTIONS
Shut off electrical power at the
fuse box before making any
connections. All wiring must comply with local codes.
LINE VOLTAGE
: Connect the power cord to the line voltage
specified on the motor and nameplate. The power cord must
be connected to a constant source of power (not a fan or other
device that runs intermittently).
If the power cord does not havea plug, wiring is as
follows: green (or yellow/green) - ground. Black (or brown) -
line. And White (or blue) - neutral.

CONNECTING THE PIPING
• Run flexible tubing or pipe from the evaporator
drain into one of the three pump inlets. Be sure
the inlet piping is sloped downward to allow grav
ity flow. Extend the inlet piping into the tank from
1 to 3 inches to ensure that it will not interfere with
proper float operation. Be sure that the inlet piping
is cut at an angle where it enters the tank.
• The outlet piping should be flexible tubing
secured with a hose clamp (not provided) or pipe
(3/8 in, I.D. maximum to prevent excessive flow
back to the unit). From the condensate unit, ex
tend discharge piping straight up as high as
necessary. Do not extend this line above the
head/GPH of the particular model being installed.
From this high point, slope the discharge line down
slightly to a point above the drain area; then turn
down and extend to a point below or approxi-
mately level with the bottom of the condensate
unit. This will give a siphoning effect which will
improve efficiency of the condensate unit and will,
in most cases, eliminate the need for a check
valve. If it is not possible to slope the discharge line
down, make an inverted "U" trap directly above
the pump at the
highest point.

Installation
TESTING THE PUMP INSTALLATION
• Turn on power.
• Remove the motor/tank cover assembly and hold
level.
• Test the motor switch by raising the motor switch
float with a finger. The motor should turn on just
before the float contacts the cover.
• Test the safety switch by raising the safety switch
float with a finger. The safety switch should
activate before the float contacts the cover.
• Replace the motor/tank cover assembly on the
tank.
