INTRODUCTION
Thank you for selecting the Toyo submersible pump.
In order to ensure that you receive the maximum benefit of this equipment, it is required that this
INSTRUCTION & SERVICE MANUAL be thoroughly read prior to use, and that all instruction be carefully
followed.
WARNING!!
This is not explosion-proof or spark-proof.
It should not be operated in any area where flammable or
explosive gases, vapors, liquids or particles are or may be
present or where a spark could cause a danger or fire or
ex
p
losion.
These ruggedly built, portable, electrically powered submersible pumps are designed for trouble-free
operation in the removal of water from enclosed sumps, irrigation areas or serve a variety of general
dewatering/pumping chores (applications).
The pumps feature an oil-filled chamber between the pump section and the electric motor section that has
a high efficiency sealing system.
This sealing system prevents water from entering the motor and also permits extended dry running
without the concern for seal damage.
These pumps are also equipped with induction-type motors that have built-in overload protection to guard
against motor burn out due to over-current, over-heating or other mechanical over-load conditions.
Please fill in the information below and retain. These information will be necessary when requesting parts
or service. PUMP MODEL DL -1-110

OPERATING & MAINTENANCE INSTRUCTIONS
PRIOR TO OPERATION
1) UNPACKING AND INSPECTION
a) Always lift the pump by the handle-not the cabtyre cable.
If the pump must be suspended in a well or pit, a rope or chain should be attached to the pump
handle.
b) Check the nameplate information to ensure that the equipment received is that which was
ordered.
c) Carefully inspect the pump to be sure that shipping damage has not occurred.
2) INSPECTION OF PUMP
a) Check to determine that the power circuit and/or receptacle are adequate to handle
voltage/current rating of the motor-pump.
b) Ensure that cabtyre cable/extension cord is free from damage and that grounding wire/circuit is
operational.
CAUTION: Do not operate this pump unless it is connected to a properly wired grounding circuit
since serious personal injury may result from electrical shock. Disconnect the cabtyre
cable from the power source, before servicing this pump.
Do not use this pump in the water where person(s) is (are).
INSTALLATION & OPERATION
a) Be certain that the pump is mounted on a solid, flat base or suspended by a rope or chain
attached to the pump handle.
CAUTION: Do not use the electrical cable or discharge hose to suspended the pump.
Always attach suspension rope to the pump handle.
b) Use the shortest possible length of discharge hose to assure you minimize friction losses and
maximize your pump flow.
c) Make certain that the cable and/or receptacle from which it draws power is protected and away
from water or pump discharge hose to prevent accidental shock or electrical short circuiting.
d) The pump model has a built-in overload protector which senses over-current, over-heating, or
over-load conditions.
The operation of this protector is such that should any of these conditions exits, the power supply
will be interrupted until motor cooling has taken place. After cool-down has occurred, the pump
will automatically re-start and continue to be protected in this way as long as the condition exists,
but we request you to check and remove the cause.

Note: This is a protection device and is not intended to replace external controls.
e) When cable extension is necessary, extended cable size must be adequate to avoid low voltage
conditions , which may cause motor burn out. Select the proper gauge size and minimize length
of the extension cable not to cause a large voltage drop. If you are not sure, it is recommended
to consult with the Toyo representative office or Toyo suppliers nearest you. When extending the
cable, be careful not to submerge the splice into the water to avoid the possibility of electrical
shock.
f) Connection to Power Source
DL-110: Plug in or connect to one phase power source.
CAUTION: Be sure to provide an adequate grounding and to use a ground leakage circuit
breaker.
AFTER OPERATION
To keep the pump in good condition and maintain high pumping efficiency the following inspections
should be carried out after each fifty (50) hours of operation. (See Fig.A6470)
a) Remove Strainer-stand (item #23) and Pump Casing (#20). Clean out any solids and/or mud,
sand, stones or other foreign material which may have collected in the Pump Casing.
b) Check the Impeller (#21) for wear, obstruction or foreign material accumulation. If parts are
extremely worn, replacement should be made at the first opportunity.
c) After the inspections, clean the inside and outside of pump with clean water. When it is stored,
keep it in a dried condition.
REGULAR INSPECTION
1) LUBRICANT CHECK (See Fig.A6470)
Check the mechanical seal by inspecting the condition of the lubricant in the oil chamber. You may
readily determine the condition of the mechanical shaft seals based upon contamination level in the
oil.
a) Lay the pump on its side with Oil Plug (#35) facing upwards.
After unscrewing the plug, turn the pump over so that the hole faces downward. Drain and collect
the lubricant in a clean suitable container.
b) If the lubricant is clear and clean (not milky appearing or no water present), the seals should be in
a good condition.
c) Refill the chamber with fresh lubricant, using a good multiviscosity grade lubricant (Turbine Oil
ISO VG #32).
d) Extreme discoloration (milky appearing or yellowish-gray) or free water in the lubricant requires
immediate replacement of Mechanical Seal (#25) and V- Ring(#26).
e) When inspection is complete, replace the oil plug and carefully tighten to prevent leakage.
Note: Replace Packing of the oil plug, if it is found to be defective.
Periodic inspection and replacement of the oil should be made as follows:
*Inspection Cycle: Every 1,000 hours of running time
*Replacement Cycle: Every 2,000 hours of running time
But we recommend inspection once a year even if running time is less than above.

Required lubricant volume is as follows and recommended lubricant is Turbine Oil ISO VG # 32. For your
convenience, other lubricants equivalent to ISO VG # 32 are listed as follows.
If it is difficult to get these turbine oils, engine-oil (10W-30/40) can be used alternatively.

2) ELECTRICAL CHECK (MEGGER TEST)
Whenever the pump is serviced, it is a good maintenance/safety practice to check the insulation
strength of the motor and cabtyre cable in the following manner to prevent electrical shock
accident(s).
a) Disconnect the cabtyre cable from the power source.
b) Using the 500 VDC Megger Tester, check the electrical insulation of each leg of the wiring circuit
in combination with the ground lead (green or green/yellow).
c) If any reading is less than one (1) meg-ohms (M<), it indicates damage to the cabtyre cable
and/or the motor.
d) Disconnect the cabtyre cable from the motor and Megger Test the insulation strength of the motor
itself.
e) Any reading more than ten (10) meg-ohms (M<) requires immediate replacement of the Cabtyre
Cable.
Any reading less than ten (10) meg-ohms (M<) indicates electrical leakage due to the presence of
water or dampness in the motor in which case the motor must be dried thoroughly.
If after drying, the condition still exists, there is a strong probability that the motor is in need of
repair.
CAUTION: It is absolutely imperative that appropriate corrective action/repair be performed
before the pump is returned to service if it will not pass the Megger Test.
Serious personal injury can result from electrical shock.
The above maintenance inspection, if it is performed regularly, will result in greatly
improved pumping efficiency and pump life.
