Little Giant 1-YS User manual

INTRODUCTION
The 1-YS pump is designed for submerged use only. Its motor is
hermetically sealed in a diecast aluminum housing, which is oil-filled
for heat transfer and permanent lubrication. It is intended to pump
unheated metal parts-cleaning solvent that is UL classified as PJQU
as described in the Gas and Oil Equipment Directory. These are
refined petroleum distillates that are free from the tendency to heat
spontaneously. They have a closed cup flash point not lower than 100
degrees F. These are typical fluids that are compatible with the pump
materials (except the power cord.) See Installation step 1.
NOTE: This pump is intended for use only in parts cleaners
listed by Underwriters Laboratories. The combination of the fluid
pumped, the pump, and the design of the parts washer will
determine if additional safety devices, such as a low liquid level cut
off, are required. Refer to parts washer manufacturer’s instructions
to see if this is required.
SAFETY GUIDELINES
Before servicing the pump, see solvent and equipment
manufacturer’s instructions for further safety information and
possible hazards.
Follow all local electrical and safety codes, as well as the National
Electrical Code (NEC) and the Occupational Safety and Health Act
(OSHA).
This pump must be properly grounded while in use to protect the
operator from electrical shock.
Always disconnect power source before working on the pump. If
the power disconnect point is out of sight, lock in the open position
and tag to prevent unexpected application of power.
Do not attempt to make your own parts cleaners.
The low flash point of these combustible liquids does present
a moderate fire hazard. Operating the pump fully submerged
offers added protection from fire risk. For other solvent handling
precautions, consult the material safety data sheet (OSHA-20 form,
or equivalent) for the solvent used.
Use only UL-approved metal parts cleaning solvents. The use of fluids
such as gasoline and lower flash point solvents is dangerous and
may cause explosions or fire. Solvents other than UL-approved metal
parts cleaning solvents will void the warranty of this product.

INSTALLATION
WARNING: Do not allow the pump’s power cord to come in
contact with solvent. The solvent may damage the cord insulation,
causing the cord to become stiff or lower its insulating properties.
The pump is supplied with a three-conductor power cord. The third
conductor is to ground the pump to prevent possible electrical
shock hazard.
1. Seal the power cord inside of liquid-tight, ½” NPT steel
intermediate metal conduit. Use caution to ensure that cord will
not be nicked or cut.
2. Consult pump nameplate data for proper voltage and frequency.
Please note, the black (or brown) and white (or blue) wires are
live and the green (or green/yellow) wire is ground.
3. Be sure that the pump is fully submerged in the cleaning
solvent.
4. The pump power supply cord must be connected to a properly
grounded, grounding-type receptacle.

MAINTENANCE
WARNING: UNPLUG THE UNIT BEFORE ATTEMPTING TO
SERVICE OR REMOVE ANY COMPONENT!
CAUTION: This unit is permanently lubricated. Oiling is not
required. Do not open the sealed portion of the unit or remove
housing screws.
Periodic cleaning of the pump parts will prolong the life and
efficiency of the pump. Refer to Fig. 2 for the assembly and
disassembly of the pumping head.
1. Lightly clean any corrosion or debris that may clog the impeller.
Use a brush and penetrating oil and lightly scrape. NOTE: Do
not allow sediment from parts being washed to build up and
restrict the flow of fluid into the pump.

2. Turn the impeller by hand to make sure it is free. If it does
not turn or if pump is tripping circuit breaker, or not operating
properly after cleaning, return to Little Giant or its authorized
service center. Do not attempt repairs yourself. If it does turn,
replace volute and re-install into parts washer.
3. Be certain power cord is protected from solvent and has no
nicks or cuts.
Do not remove housing screws.Will void warranty.

TROUBLESHOOTING
CAUTION: Do not open the sealed portion of the unit or remove
the housing screws.
1. Should the unit fail to operate, check the following:
a. Power supply and connections
Form 993855 - 12/2007

b. Is the pump below liquid level?
c. Is air trapped in the pump head?
d. Is there sediment build-up over pump inlet?
2. An air lock or bubble will prevent the unit from pumping.
Trapped air can usually be removed by turning the pump
off and restarting. Ensure that the discharge line is sloping
upward to prevent formation of air pockets.
3. If these operations do not restore the unit to full service, call
your dealer or service technician.
