PE-2YSA
Introduction
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 low liquid
level cut off are required. Refer to parts washer manufactur- er’s instructions to see if this is required.
The PE-1YSA and PE-2YSA are designed for submerged use only. The pump motors are encapsulated in an epoxy resin and
are intended to pump the following fluids:
Metal parts cleaning solvents - Unheated metal parts cleaning solvents (clas- sified as PJQU as described in the Gas and Oil
Equipment Directory). These solvents are refined petroleum distillates, which are free from tendency to heat
spontaneously. They have a closed cup flash point not lower than 100°F. 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. Aqueous
cleaning solutions - These are water-based solutions that should not be used in excess of 140°F and a maximum pH of 12.
These are typical fluids that are compatible with the pump materials.
1. 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.
2. Use any metal parts cleaning solvents that are UL approved or aqueous cleaning solutions. The use of fluids such as
gasoline and lower flash point solvents is dangerous and may cause explosions or fire.
INSTALLATION
The power cord supplied with this pump should not be in contact with solution. The solution may attack the cord insulation
causing cord to become stiff or lowering the 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, 1/2" NPT, steel intermediate metal conduit. Use caution to ensure the cord
will have no nicks or cuts.
2. Consult the pump nameplate data for proper voltage and frequency. The black (or brown) and white (or blue) wires
are live and the green (or green/ yellow) wire is the ground wire.
3. Be sure that the pump is fully submerged in the cleaning solution.
4. Connect the pump power cord to a properly grounded, grounding–type receptacle.
5. The pump must be protected by a GFCI (Ground Fault Circuit Interrupter) when pumping water-based solutions.
MAINTENANCE
DISCONNECT THE PUMP FROM THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE OR REMOVE ANY COMPONENT!
1. This unit is permanently lubricated. Oiling is not required.
2. Periodic cleaning of the pump parts will prolong the LIFE and EFFICIENCY of the pump. Refer to Figure 2 for the
assembly and disassembly of the pumping head.
3. Lightly clean any corrosion or debris which 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.
4. 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. Do not attempt repairs yourself. If it does turn replace volute
and re–install into parts washer.
5. Be certain power cord is protected from solvent and contains no nicks or cuts.
