Model TPA-250 – Operating Instructions and Parts Manual
APPLICATION AND OPERATION
Do NOT use pump if any part of the switch housing
or probe is cracked, broken, or missing.
Always disconnect
electric supply before
attempting to install, service, relocate, or
perform any maintenance. If the power source
is out of sight, lock and tag in open (off)
position to prevent unexpected power application. Failure to do so
could result in fatal electrical shock!
Electric shock hazard. Use only
Underwriters Laboratories (UL)- listed
extension cord with #16 gauge or larger wire that is labeled
for outdoor use. Use polarized grounding type plugs only.
Polarized plugs have one blade slightly wider than the other
and can only be inserted one way into the outlet. Do NOT handle plug
connector near water. Failure to follow these instructions will result in
serious injury or death.
This unit is NOT designed for use as a
sump pump or in sump applications.
This unit is NOT designed for use in septic tanks or
underground vaults to pump raw sewage or effl uents.
NEVER use in hazardous or explosive locations.
1. This pump has been designed with 1-1/4 in. NPT discharge
connection size. Attach pipe or fitting to the discharge or use
the supplied garden hose adapter. Thread the female end of the
garden hose to the male end of the elbow.
2. Be certain to use a hose washer (not included) on the garden
hose for correct pump operation.
3. For best pump performance, unwind the hose before starting the
pump. This will help remove any kinks or binds in the hose and
allow the unit to pump with less restriction.
4. Set the pump on a hard, flat surface in the water. Do not set the
pump directly on mud or sand surfaces. This will cause the inlet
screen to clog.
5. The water level must be at least 1-3/4 inches for the pump to
cycle, prime, and operate. Water levels less than 1-3/4 inches
will not allow the impeller to contact water, therefore, no water
will be pumped.
Do not handle pump with wet
hands or when standing in water or
on a damp surface when the unit is operating or fails to
operate. Always disconnect pump power cord from power
source before handling.
6. Plug the pump into a 120 volt GFCI protected outlet. The pump
will start automatically when the water reaches a depth of 1-3/4
inches. A priming delay of 2 seconds is programmed into the
control to allow time for air to escape from the pumping chamber.
7. The pump will stop automatically once water has been removed
to a depth of approximately 3/8 of an inch above the hard
surface. The pump will not restart until the water depth rises to
1-3/4 inches or greater.
8. The pump will not allow itself to run dry. Once the pump detects that
water is no longer being removed, it will shut down automatically.
The pump must remain upright at all times in order for the water
detection to function. The shaft seal depends on water for
lubrication. Do not allow the pump to operate on its side or inverted.
Do NOT alter the pump to override the automatic
water detector. The shaft seal depends on water for
lubrication. Overriding this pump feature can cause the pump to run dry
and may damage the shaft seal and cause pump failure.

MAINTENANCE AND TROUBLESHOOTING
before attempting to install, service, relocate, or perform
any maintenance. Failure to do so could result in fatal
electrical shock.
Minimal service is required for this pump. The motor housing of the
pump is completely sealed and requires no service. If pump should
fail to operate, perform the following troubleshooting guidelines:
1. Verify pumping height does NOT exceed 15 feet
(See Figure 1). If pumping height is greater than 15 feet,
this pump will NOT operate.
WATER LEVEL MINIMUM:
1-3/4 INCHES
Figure 1 - Pumping Height
2. Verify water depth is 1-3/4 inches or greater (See Figure 1).
these instructions will result in serious injury or death.
3. To verify pump is operating correctly.
a. Disconnect pump from power source.
b. Connect hose adapter and discharge hose to pump.
c. Immerse pump in a bucket or tub of water at least 1-3/4
inches in depth.
d. Place the other end of the discharge hose outside the
bucket, so the water will pump out.
e. Plug power cord into a grounded 120 volt GFCI power
outlet. The pump should start after 2 seconds of detecting
water. Once the pump removes the water to a depth of 3/8
inch, the pump will stop automatically.
f.
If pump does NOT operate, unplug power cord and proceed
to maintenance – step 5 (page 3).
4. To verify discharge hose is free from a blockage.
a. Connect hose to another water source such as a faucet.
If water flows through hose, return to step 3a. If water is
restricted, verify discharge hose is unwound. Remove all
kinks, bends, or obstructions in hose.
b. If pump is still NOT operating, proceed to step 6 (page 3).
