of 90 dBA. Wear hearing protection while working
with or near the pump.
!
CAUTION
Installation to be performed only by properly
trained individuals.
!
WARNING

WARNING
Section 6.1
Compressed Air Supply
Unless otherwise noted, all air line accessories for
the pump air drive should have, at minimum, a 1/2
"
FNPT connection. The tubing/piping used to
connect the components should have the maximum
ID the pressure rating will allow. Reducing the size
before the air inlet will reduce air pressure flow and
reduce flow rate of the pump.
NOTICE
The main air drive connection port on the pump is a
female 1
"
FNPT and is located in the spool base housing.
An additional female 1/8
"
FNPT air pilot valve connection
port is located in the middle plate at the opposite side of
the 1
"
NPT air inlet.
This pilot connection must be plumbed to an unregulated
and filtered air source. The purpose of this connection
is to aid in low pressure differential start-up and restart
of the pump while providing a more accurate pressure
control. The pump will not function if this unregulated air
supply is not connected to the pilot valve supply port.
The use of an air line lubricator is not required
and is not recommended.
The oil in the air
lubricator will cause the factory installed grease to
be purged from the pump. Once an air lubricator is
used the pump can never again be operated without
an air lubricator.
NOTICE
An air line filter with a minimum 5 microns filtration rating
must be used on the supply line. If the air supply is not
dry, a mist separator must be used to remove moisture in
the air line.
The pump is designed to function from 20 psi to 110 psi
(1.4 to 7.6 bar) air input pressure, however maximum
inlet air pressure is limited by the maximum liquid output
pressure.
