5. ASSEMBLY
5.1.
The air control unit items (fig.1. 2 & 3) have polycarbonate bowls and must not be installed where the bowls may be exposed to
materials incompatible with polycarbonate such as certain solvents and chemicals, or where fumes can weaken the bowls. If this is
unavoidable, an extension air line hose may be placed between the pump unit and the air control unit, but should not exceed 2 metres
(6½ft) in length. Note that a mounting bracket (fig.1.5) is supplied to provide support for remote positioned air control unit.
WARNING! Clean new air lines ensuring all metal shavings have been removed before connecting the pump and control unit. Any dirt in
‰
the inlet lines could damage the unit and may invalidate the warranty.
5.2.
Connect filter-regulator to lubricator using one of the fittings (10). Note the air flow direction arrows on each unit and that lubricator must
be between pump and filter-regulator. Using the second fitting (10) connect the lubricator outlet to the pump air inlet.
5.3.
Screw gauge (4) into filter-regulator port, choosing the port which will provide easiest gauge visibility in final installed position. Plug the
remaining gauge port with plug (9).
5.4.
Screw air hose (6) into filter-regulator inlet port. Secure all connections (but do not over tighten).
6. INSTALLATION
DO NOT install the unit where it may be damaged by moving apparatus, or may endanger personal safety.
8
6.1.
Secure wall mounting bracket (fig.1.8) to wall, as shown in fig.3, ensuring wall and attaching screws are adequate to take the weight of
the pump and the pull of the suction and output hoses.
6.2.
Remove the knurled mounting ring from the pump body and pass the pump unit through the mounting bracket and secure with the
knurled ring, (fig.3).
6.3.
Attach suction hose (fig.2.7) to inlet at base of pump unit. Attach output line (¾" bore - not supplied, (see fig.2) to the pump output port.
6.4.
The bowl of the filter-regulator (fig.2.2) is fitted with an automatic drain valve the outlet of which may be piped away using suitably sized
flexible tube.
6.5.
Remove lubricator (fig.2.3) oil filler plug and fill with good quality air tool oil (Sealey ATO/500 500ml size or ATO/1000 1L size) checking
the maximum level marked on the side of the unit.
Note: The installation of a wall bracket next to the pump, to support the suction hose when not in use, is recommended.
Use PTFE tape or similar on all connections to ensure leak-free joints.
7. OPERATION
7.1.
The regulator should be set at 6 bar/90psi. It is important to maintain the correct operating pressure to ensure that the control valves
and connectors are not damaged and to prevent leakage in the delivery lines.
7.2.
Connect the suction hose (fig.2.7) to the oil drain unit and ensure the outlet hose will dispose of the waste in accordance with local
authority regulations. DO NOT pollute the environment by the uncontrolled discharge of waste products.
WARNING! DO NOT operate pump dry - suction line must be connected to drainer before turning on.
‰
7.3.
Before turning on air supply for the first time ensure that pressure regulator knob (fig.4.A) is unwound (anticlockwise) so that there is no
load on the regulator spring. Turn on air supply. Regulator output gauge (fig.2.4) should show zero. Turn regulator knob clockwise, slowly,
until gauge shows 6 bar (90psi) - pump will start at approx. 2 bar. Lock knob with locking ring (fig.4.B) to prevent accidental movement.
Note: When resetting the regulated pressure always start from below the new required pressure and adjust up.
7.4.
Check that there are no leaks from any of the hoses or fittings.
7.5.
When pumping is complete turn the air line off. Disconnect suction hose from drain unit and store. Wipe up any spillage.
Note: Waste oil will not pump if its viscosity is too high.
8. MAINTENANCE
WARNING! Ensure that the pump is disconnected from the air line and that there is no pressure in the output line before attempting
‰
any service or maintenance.
Note: It is essential that dirt and moisture are kept out of the air supply to the pump. Drain air supply system and clean filters regularly.
8.1.
AIR LINE LUBRICATOR AND WATER TRAP (FIG.2.3)
8.1.1.
This unit is designed to automatically lubricate the pump via the air supply. The unit must be kept topped up with good quality air tool
oil (Sealey reference: ATO/500 - 500ml size or ATO/1000 - 1L size). To adjust the oil flow turn the oil regulator on the top of the unit.
Turn screw anticlockwise to increase the flow and clockwise to decrease flow - set to minimum flow for this application.
