SAFETY − SECTION A
This information applies to Gorman-
Rupp Automatic Air Release Valves. Re-
fer to the manual accompanying the
pump and power source before at-
tempting 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 installing the Automaitc Air Re-
lease Valve, check the chemical com-
patibility of the valve components with
the liquid being pumped. Misapplica-
tion of materials could result in damage
to the valve and/or danger to personnel
as a result of valve failure.
Before attempting to service the Air Re-
lease Valve:
1. Familiarize yourself with this man-
ual.
2. Disconnect or lock out the power
source to the pump or isolate the
Air Release Valve to ensure that it
will remain inoperative.
3. Allow the pump and liquid to com-
pletely cool if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
If the application involves volatile, cor-
rosive or hazardous liquids, wear pro-
tective safety equipment, such as
goggles, rubber gloves and apron when
servicing the pump or Automatic Air Re-
lease Valve.
If the application involves petroleum
products such as fuel oil or gasoline,
provide adequate ventilation, prohibit
smoking and wear static-resistant
clothing and shoes before servicing the
Automatic Air Release Valve. Clean up
all fuel spills immediately after occur-
ence.
Some leakage (1 to 5 gallons[3,8 to 19 li-
ters] per minute) will occur when the
valve is fully closed. Be sure the bleeder
line is directed back to the wet well or
tank to prevent hazardous spills.
