Installation Guide

INTRODUCTION
EN
Your Little Giant condensate pump is designed as an automatic condensate
removal pump for water dripping off an air conditioner evaporative coil. The
pump is controlled by a float/switch mechanism which turns the pump on when
approximately 3-1/2” of water collects in the tank, and automatically switches off
when the tank drains to approximately 2”.
Read these instructions carefully. Failure to follow these instructions voids all
warranty, and could result in bodily harm or property damage. All wiring and
plumbing must be permanent, and comply with local codes. Shut off electrical
power at the fuse box before servicing the pump.
The 1978 National Electrical Code, Article 680-14(a) requires ground fault circuit
interrupter (GFCI) be installed in the branch circuit supplying fountain equipment,
ponds, etc. See your local electrical supply dealer for various brands of GFCI
devices.
SAFETY GUIDELINES
Do not use to pump flammable or explosive fluids such as gasoline, fuel oil,
kerosene, etc. Do not use in explosive atmospheres. Pump should be used with
liquids compatible with pump component materials. Do not handle the pump with
wet hands or when standing on a wet or damp surface or in water. This pump is
supplied with a grounding conductor and /or grounding type attachment plug. To
reduce the risk of electrical shock, be certain that it is connected to a properly
grounded grounding type receptacle. In any installations where property damage
and/or personal injury might result from an inoperative or leaking pump due to
power outages, discharge line blockage, or any other reason, a backup system(s)
and/or alarm should be used. Support pump and piping when assembling and
when installed. Failure to do so may cause piping to break, pump to fail, motor
bearing failures, etc.
INSTALLATION
1. Before installing pump, allow air conditioner to cycle several times, collecting
condensate in a separate container to help flush any residual oils that may
remain in the system.
2. Carefully unpack the pump. Remove the cover assembly from the tank and
remove all packing from around floats. Check each float assembly for free
movement. Place cover assembly on tank.
3. Mount the pump. There are two vertical mounting surfaces (Fig. 1) on one side
of the tank to mount on side of air conditioning unit, or nearby wall. Mounting
holes can be drilled in this surface, but should not exceed one inch from the
top of the tank to prevent possible spillage of water.
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 the 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, wiring is as follows: green (or green/yellow)–ground. Black (or
brown)–line. White (or blue).
3. Safety Switch-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 type plug is used on 230v units, a 3.0 amp fuse is recommended.
PIPING
1. Run flexible tubing or pipe from evaporator drain into pump inlet. Be sure inlet
piping is sloped downward to allow gravity flow (Fig 3).
2. The outlet piping should be flexible tubing or pipe (3/8” I.D. maximum to
prevent excessive flow back to unit). From condensate 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.
SERVICE INSTRUCTIONS
1. Disconnect the pump from the power source.
2. Oil the motor (Fig. 4) at the start of each air conditioning season. Use SAE
number 10 or 20 non-detergent oil. Do not over oil.
3. Be sure the floats move freely. Clean as necessary.
4. Remove the volute and check for obstructions. Clean as necessary.
5. Clean the tank with warm water and mild soap.
6. Check inlet and outlet piping. Clean as necessary. Be sure there are no kinks
in the line that would inhibit flow.
TESTING
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. Use caution 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.

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 3 po 1/2 d eau s’accumule dans le réservoir. La pompe s’arrête
automatiquement lorsqu il ne reste plus qu environ 2 po d’eau.
Lire attentivement les présentes instructions. Le non-respect de celles-ci annule
toute garantie et peut causer des atteintes aux personnes ou à la propriété. Tous les
branchements de fils et de tuyaux doivent être permanents et conformes aux codes
en vigueur. Interrompre le courant à la source avant de faire l’entretien de la pompe.
L’article 680-14(a) du Code national de l’Électricité américain de 1978, ainsi que
plusieurs autres codes en vigueur dans d’autres pays, exige l’installation d’un
interrupteur avec mise à la terre (GFI) sur le circuit d’alimentation de fontaines,
d’étangs, etc. Consultez votre détaillant d’équipement électrique pour plus
d’informations sur les types de GFI.
DIRECTIVES DE SECURITE
Ne pas utiliser pour pomper des liquides explosifs ou inflammables (essence, huile,
kérosène, etc.) Ne pas utiliser dans un environnement propice aux explosions. Utiliser
avec des liquides compatibles avec les matériaux de la pompe. Ne pas manipuler la
pompe les mains humides, les pieds posés sur une surface mouillée ou humide, ou
les pieds dans l eau. Votre pompe vient avec un fil de mise a la terre et/ou une prise
a trois branches. Afin de réduire le rusque de choc électrique, s’assurer que la pompe
est branchée a une prise correctement mise a la terre. ‘Utilisation n ou de plusieurs
systèmes auxiliaires et/ou d’un système d’alarme est recommandée pour toute
installation potentiellement dangereuse (fuite ou défectuosité causées par une
