neither operator safety nor pump integrity are compromised by the installation. Pumps and related
equipment must be installed and operated according to all national, local and industry standards.
The following are used to alert maintenance personnel to procedures which require special attention, to those which could damage equipment, and
to those which could be dangerous to personnel:
Immediate hazards which WILL result in
severe personal injury or death. These
instructions describe the procedure required and the injury which will result
from failure to follow the procedure.
Hazards or unsafe practices which
COULD result in severe personal injury
or death. These instructions describe
the procedure required and the injury
which could result from failure to follow
the procedure.

SAFETY - SECTION A
This information applies to operation
and maintenance of the UNIT 608 tankleenorr. Refer to the manual accompanying the electric motor before attempting to begin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and precautions for each specific application.
Therefore, it is the owner/installer’s responsibility to ensure that applications
not addressed in this manual are performed only after establishing that neither operator safety nor pump integrity
are compromised by the installation.
OM−01228
Before operating or servicing the pump,
be certain proper safety practices are
followed. Provide adequate ventilation,
prohibit smoking, wear static-resistant
clothing and shoes. Clean up all fuel
spills immediately after occurrence.
Connect the ground wire to the tank fill
pipe or other ground connection before
operating the unit. Static electric buildup could develop during cleaning operation, causing hazardous sparks.
Before attempting to open or service the
pump:
1. Familiarize yourself with this manual.
2. Unplug the motor to ensure that
the pump will remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Vent the pump slowly and cautiously.
6. Drain the pump.
This pump is designed to handle water,
gasoline or other petroleum products.
Do not attempt to pump corrosive or
highly volatile liquids which may damage the pump or endanger personnel as
a result of pump failure.
Do not operate the pump against a
closed eductor control valve for long
periods of time. This could bring the liquid to a boil, build pressure, and cause
the pump casing to rupture or explode.
Overheating may produce dangerous
fumes. Use extreme caution when venting the pump, or when removing covers,
plates, plugs or fittings.
Overheated pumps can cause severe
burns and injury. If overheating of the
pump occurs:
1. Stop the pump immediately.
2. Allow the pump to completely cool
if overheated.
3. Refer to instructions in this manual
before re-starting the pump.
PAGE A − 1SAFETY
UNIT SERIESOM−01228
The electrical power used to operate
this unit is high enough to cause injury
or death to personnel. Connect the electrical plug to a grounded power supply;
never use gas piping as an electrical
ground. Be sure the power supply is of
the correct voltage and phase. Do not
run the motor if the power supply is not
within acceptable limits. If a circuit
breaker or fuse is tripped, examine and
correct the problem before re-starting
the unit.
Inspect the suction hose regularly for
cuts, punctures or severe abrasion before operation. Replace the entire hose
assembly if there is any possibility of
leakage or exposure of the integral
spring steel strap inside the hose.
Never attempt to change the electrical
plug or alter the length of the power cord
with a splice. Equipment failure or personal injury could result if all connections are not waterproof and compatible
with the current used.

PREINSTALLATION INSPECTION
The pump assembly was inspected and tested before shipment from the factory. Before installation,
inspect the unit for damage which may have occurred during shipment. Check as follows:
a. Inspect the pump, reel assembly, hose and
motor for cracks, dents, damaged threads,
and other obvious damage.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.
c. Carefully read all tags, decals, and markings
on the unit, and perform all duties indicated.
d. If the pump and motor have been stored for
more than 12 months, some of the compo-
nents or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump service.
e. Check to ensure the following standard
equipment items are included with the pump
assembly:
Detachable reel assembly.
42 foot long hydrocarbon-resistant hose.
8 foot long connector hose.
15 foot long suction and discharge hose.
12 foot long stainless steel standpipe.
10 foot long ground wire.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
