ELECTRICAL CONNECTIONS
1. Shut off electrical power at fuse box before making any
connections. All wiring must comply with local codes.
2. Line voltage: Connect power cord to line voltage specified
on motor and nameplate. Power cord must be connected
to a constant source of power (not a fan or other device that
runs intermittently). If power cord does not have a plug, wir-
ing is as follows: green (or green/yellow)—ground. Black (or
brown)—line. White (or blue)—neutral.
3. Safety switch (Figures 2 and 3): The safety overflow switch
should be connected to a class II low voltage circuit. Typical
hook-up of "NC" circuits would be:
N.O.—When water rises, circuit opens to turn off heating or
cooling equipment
N.C.—When water rises, circuit closes to activate a bell or
alarm
4. If fused plug is used on 230V units, a 2.0 amp fuse is recommend-
ed.
Figure 4.
1. Run flexible tubing or pipe from evaporator drain into pump
inlet. Be sure inlet piping is sloped downward to allow gravity
flow (Figure 4).
2 The outlet piping should be flexible tubing or pipe (3/8" I.D.
maximum to prevent excessive flow back to unit). From con-
densate unit, extend 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
discharge line down slightly to a point above drain area; then
turn down and extend to a point below or approximately 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 discharge line down, make an inverted
"U" trap directly above the pump at the highest point.
3. If debris collects in the check valve and prevents it from sealing
properly, the volume of water draining back into the tank from
the 3/8" tubing may cause the pump to cycle on and off
continuously without lifting water the full height of the discharge
tubing. In this event it is recommended that the 1/4" adaptor
which is provided be used with 1/4" I.D. tubing. NOTE: Thread
sealant must be used when using 1/4" adaptor. This will lower
the discharge tubing volume below the pump cycle volume
and result in full discharge lift.

SERVICE INSTRUCTIONS
MAKE CERTAIN THE UNIT IS DISCONNECTED FROM THE POWER
SOURCE BEFORE ATTEMPTING TO SERVICE OR REMOVE ANY
COMPONENT!
1. Be sure the floats move freely. Clean as necessary.
2. Remove the volute and check for obstructions. Clean as nec-
essary.
3. Clean the tank with warm water and mild soap.
4. Check inlet and outlet piping. Clean as necessary. Be sure
there are no kinks in the line that would inhibit flow.
TESTING
Figure 5.
1. Turn on power.
2. Remove motor/tank cover assembly and hold level.
3. Test motor switch by raising motor switch float with finger
(Figure 5). Motor should turn on just before circlip on stem
contacts stem guide.
4. Test safety switch by raising safety switch float with finger.
Safety switch should activate before float contacts cover.
5. Replace motor/tank cover assembly on tank.
This pump is suitable for gas furnace condensate applications.
Caution must be taken to ensure acidity of condensate does not
fall below the average pH of 3.4 (to prevent localized pocket of
acid that acts like a battery causing pitting) by routinely cleaning
or flushing tank with fresh water.
F INTRODUCTION
Votre pompe à condensats Little Giant est conçue comme une
unité automatique d évacuation des condensats. Elle évacue
l eau condensée s égouttant de la volute de l évaporateur d
un système de climatisation. La pompe est actionnée par un
mécanisme flotteur/interrupteur lequel entraîne le démarrage de
la pompe lorsque environ 1 po d eau s accumule dans le réservoir.
La pompe s arrête automatiquement lorsqu il ne reste plus qu
environ 1/2 po d'eau.
Votre nouvelle pompe Little Giant a été fabriquée avec les meil-
leurs matériaux et avec le plus grand soin. Elle a été conçue pour
foncionner bien et longtemps.
Les pompes Little Giant sont soigneusement emballées, et testées
pour assurer une livraison et un fonctionnement sans problèmes.
Lorsque vous recevez votre pompe, examinez-la attentivement
pour vous assurer qu il n y a pas eu de pièce cassée ou endom-
magée pendant l acheminement.
S il y a eu des dégats, prenez-en note et signalez-le au magasin
où vous avez acheté la pompe. Ils vous aideront pour le remplace-
ment ou la réparation, si nécessaire. Cette pompe est conçue
pour pomper de l eau. NE POMPEZ PAS de produit chimique, de
solvant, d eau salée, ou de liquides épais tels que des huiles ou
de la graisse.
