PAGE A - 1 SAFETY
SAFETY ‐ SECTION A
This information applies to Prime Air
r
Series pumps. Refer to the manual ac­
companying the power source before
attempting to begin operation.
This manual will alert personnel to
known procedures which require spe­
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel.
How­
ever, this manual cannot possibly antici­
pate and provide detailed instructions
and precautions for every situation that
might occur during maintenance of the
unit. Therefore, it is the responsibility of
the owner/maintenance personnel to
ensure that only safe, established main­
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab­
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
Before attempting to install, operate, or
wire the pump control box, familiarize
yourself with this manual, and with all
other literature shipped with the control
box. Unfamiliarity with all aspects of
control operation covered in this manu­
al could lead to destruction of equip­
ment, injury, or death to personnel.
Before connecting any cable to the con­
trol box, be sure to ground the control
box. See Section B for suggested
grounding methods.
The control box provides overload pro­
tection and power control. Do not con­
nect the pump motor directly to the in­
coming power lines. If the power circuit
breaker or overload relay is tripped dur­
ing operation, correct the problem be­
fore resetting or replacing.
The electrical power used to operate the
pump control box is high enough to
cause injury or death. Obtain the ser­
vices of a qualified electrician to make
all electrical connections. Make certain
that the enclosure is properly
grounded; never use gas pipe as an
electrical ground. Be sure that the in­
coming power matches the voltage and
phase of the control before connecting
the power source. Do not make electri­
cal connections if the voltage is not
within the limits. If the overload unit is
tripped during operation, correct the
problem before restarting.
The electrical power used to operate the
pump control box is high enough to
cause injury or death. Make certain that
the control handle on the control box is
in the OFF position and locked out be­
fore attempting to service the pump. Be­
fore attempting to open or service the
control box, disconnect and/or lock out
the power supply to the control box. Tag
electrical circuits to prevent accidental
start‐up.
