SAFETY ‐ SECTION A
This information applies to Prime Aire
r
Series pumps. Refer to the manual ac­
companying the engine before attempt­
ing to begin operation.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre­
cautions for each specific application.
Therefore, it is the owner/installer's re­
sponsibility to ensure that applications
not addressed in this manual are per­
formed only after establishing that nei­
ther operator safety nor pump integrity
are compromised by the installation.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man­
ual.
2. Shut down the engine and discon­
nect the positive battery cable to
ensure that the pump will remain
inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature and make
sure the pump is cool before open­
ing any covers, plates, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau­
tiously.
7. Drain the pump.
This pump is equipped with an automat­
ic starting system, and is subject to au­
tomatic restart. Keep hands and cloth­
ing away from the unit to prevent injury
during automatic operation. Disconnect
the positive battery cable before per­
forming any maintenance. Failure to do
so may result in serious personal injury.
Do not attempt to disengage any part of
an overheated pump unit. Vapor pres­
sure within the pump casing can eject
these parts with great force when they
are disengaged. Allow the pump to
completely cool before servicing it.
This pump is designed to handle most
non‐volatile, non‐flammable liquids
containing specified entrained solids.
Do not attempt to pump volatile, corro­
sive, or flammable liquids which may
damage the pump or endanger person­
nel as a result of pump failure.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
After the pump has been installed, make
certain that the pump and all piping or
