Operating Instructions and Parts Manual
Installation
(Continued)
2. This pump operates on 120V, 60 Hz
AC, single phase or 120V DC.
3. Use an extension cord only if neces-
sary. Follow the Extension Cord
Length Table for proper gage of 3-
wire, grounding type extension cord.
Risk of fatal electrical
shock! Never cut off the
round grounding prong.
Cutting the cord or plug
will void the warranty and make the
pump inoperable.
4. Figure 2 shows a typical installation.
Threaded adapters are furnished for
attaching garden hose where condi-
tions permit its use. In no case should
the pump be more than 15 feet above
or away from inlet source. Install a
foot valve and when suction lift is
over 10 feet or when suction line is
over 10 feet.
5. The inlet line may be galvanized pipe,
plastic pipe, or reinforced hose. Small
leaks in suction line greatly reduce
efficiency of pump and may prevent
priming.
Ordinary garden
hose will collapse
under suction pressure and should not be
used in the inlet but for pressure boosting
only.
6. Use a strainer when pumping from a
creek, pond, or source where foreign
objects may be sucked into the pump.
The strainer should prevent solids
from entering the inlet line.
7. A regular garden hose may be used as
a discharge line.
Operation
Pump must be
filled with water
before operation. Running the pump dry
will cause damage to the shaft seal.
1. This unit is not waterproof or weath-
erproof and is not intended to be
used in showers, saunas, or other
potentially wet locations. The motor
is designed to be used in a clean,
dry location with access to adequate
cooling air. Ambient temperatures
around the motor should not
exceed 104˚F (40˚C).
2. Remove priming plug and fill with
water. Close plug
3. Plug power cord into GFCI protected
electrical outlet. The pump will
prime in a few minutes depending
on suction line length. Use of foot
valve on suction line is recommend-
ed.
4. In the case of pressure boosting,
turn water on before starting pump.
This force primes the pump. Then,
plug power cord into GFCI protect-
ed electrical outlet.
5. Unplug cord to turn unit off.
Maintenance
Let pump cool for
at least 20 minutes
before attempting to service. Motor may
be extremely hot. Personal injury may
result.
1. Pump should be checked periodically
for proper operation.
Always disconnect
the electrical supply
before attempting to install, service, or
perform any maintenance. If the power
source is out of sight, lock and tag in the
open (off) position to prevent unexpected
power application. Failure to do so could
result in fatal electrical shock. Only quali-
fied electricians should repair this unit.
Improper repair could result in fatal elec-
trical shock.
BRUSH REPLACEMENT
Brushes for this
pump should be
inspected after 100 hours of operation.
Pumps with excess of 100 hours of opera-
tion may stop operating or fail to start.
This could be due to worn brushes or car-
bon build-up. The brushes should be
removed and carbon removed. Worn
brushes are not covered under warranty.
Replacement brushes may be available
from Blue Angel Pumps. Call
