INSTALLATION
Air Supply
Air supplies (compressors etc) shall be sited
in a non-hazardous area with a filter on the
air intake system to prevent the ingress of
dust or similar foreign material into the parts
where compression takes place.
Pressure Relief Procedure
Before attempting any installation of agitators
onto pressure feed tanks, the tanks must be
relieved of pressure as high pressure can
cause a serious injury. Pressure is
maintained in a pressure tank after the
system has been shut down. Before
attempting removal of fill plug or cover,
pressure must be relieved using the following
steps:
1. Turn off the main air supply to the tank.
2. Close air inlet valve located on tank air
manifold.
3. Bleed off air in the tank by turning the air
relief valve thumb screw counter-clockwise.
Wait until all the air has escaped through the
valve before removing the pressure tank
cover or fill plug installation.
4. Leave the air relief valve open until you
have reinstalled the cover or fill plug.
Air Motor Lubrication (all models)
An automatic air line filter/lubricator should
be installed in the air supply line no more
than 0.5m from the air motor. The filter
should be 5 micron. Install the lubricator level
with or above the motor so the oil mist will
blow directly into or down into the motor (see
Fig. 1).
Fill the oil reservoir with SAE 10W motor oil.
Adjust lubricator to feed 1 drop of oil for
every 1400 litres (50 cfm) of air or 1 drop per
minute for continuous running.

INSTALLATION onto Pressure Feed
Tank with Agitator (Fig. 5)
1. These instructions are for fitting of the
QS-5012-CE drive unit to an installed
QMS-431-CE, 433-CE or 434-CE
agitator. (See QMS-431-CE, 433-CE and
434-CE installation section).
2. Make sure lower clamp bolt (61) is
loosened, then take the drive unit and
slide the support (60) over the bearing
assembly, making sure the square drive
on the shaft engages the drive socket of
the gearbox. Rotate the unit if necessary
to align the shaft and socket.
3. Tighten the lower clamp bolt (61) and
check the upper bolt.
4. Remove main air supply inlet valve from
the tank regulator and install service tee
(67) in open port.
5. Connect tank air supply inlet valve to
open end port of service tee (67). Install
nipple (64) in open port of service tee.
6. If not already connected, install elbow
(63) in air motor inlet port and upper
nipple (64) in open elbow port. Connect
air adjusting valve (65) to upper nipple.
Connect hose assembly (66) between
lower nipple (64) and air adjusting valve.

Agitator—INSTALLATION into
Pressure Feed Tank
1. Follow the pressure relief procedure at
the start of the INSTALLATION section.
2. Unscrew the centre blanking plug from
the tank cover.
3. Remove the paddle(s) from the shaft by
loosening the paddle clamp screw.
4. Make sure the O ring (26) is located
correctly in the housing (25). Screw
housing into the centre hole in the tank
lid. Fully tighten with a spanner (1.875
AF).
5. Refit the paddles in the position as
