SYSTEM OR PARTS AFFECTED
• S700033
OVERVIEW
• The blow-down facility within the manifold will no longer be used, we are adding plugs to the manifold
and the blow-down is being moved to the inlet valve.
• This document details the modification of the oil filter/ coalescing manifold (part # 9300026) by installing
plugs on the built-in blow-down ports (part # 4300076).
SAFETY
As it is impossible to warn of every possible hazard that may result from
operating this system, common sense and industry standard safety
practices must be observed.
Read this information before operating the compressor for the first time. Follow the information and procedures in this manual for
operation, maintenance, and repair. Observe the following items to reduce the chance of personal injury or equipment damage.
Proper service and repair are important to the safety of the service technician and the safe, reliable operation of the equipment.
Always use genuine VMAC replacement parts.
The procedures described in this service manual are effective methods of service and repair. Some procedures may require the use
of tools specially designed for a specific purpose. Anyone using a replacement part, service procedure or tool must first determine
that neither their safety nor the safe operation of the equipment will be compromised by the replacement part, service procedure
or tool selected.
Moving Parts Hazard
• Before performing service, disconnect the negative battery cable to prevent unexpected engine start.
• Do not operate the system without guards in place. If the guards are damaged or missing, replace them
before operating the equipment.
Electrical Hazard
• Ensure the ground point connection is connected to the equipment body/chassis to prevent the chance of
injury.
• Ensure the equipment is grounded appropriately.

Compressor Air and Oil Hazard
• The compressor system is under sufficient pressure that a leak could force the air/oil mixture through the skin
directly into your bloodstream. This could cause serious injury or death.
• Ensure the system is completely depressurized before attempting maintenance or repair.
• Do not use compressed air to clean off clothing or skin, compressed air can penetrate the skin causing serious
injury or death.
• Do not move or service the system while it is pressurized or operating.
• Components and hoses under pressure could separate suddenly and cause serious injury or death. If equipped,
the air receiver tank must be drained prior to servicing the system.
• Never adjust or attempt to make any repairs to the system while the engine is running. Components and hoses
under pressure could fail and cause serious injury or death.
Burst Hazard
• Serious injury or death may result from an air tank explosion.
• Never exceed manufacturer’s maximum air pressure rating.
• Do not repair components, only replace with approved parts.
• Do not tamper with, or disable factory safety equipment.
Personal Safety
• Vaporized oil is a respiratory hazard, do not breathe the compressor air.
• Do not breathe engine exhaust, internal combustion engines produce carbon monoxide, a poisonous odorless
gas which can cause death. Do not start or operate this compressor in an enclosed area.
• Always use the appropriate personal protective equipment, particularly eye and hearing protection when
operating air powered equipment.
Harmful Vapours
Breathing fuel vapours or engine exhaust can expose you to chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm.
• Always start and operate the engine in a well ventilated area.
• Do not breathe engine exhaust, internal combustion engines produce carbon monoxide, a poisonous odorless
gas which can cause death. Do not start or operate this system in an enclosed area.
• If in an enclosed area, vent the exhaust to the outside and ensure there is adequate access to fresh breathable
air.
Burn Hazard
• The engine, exhaust and the compressor system get very hot during operation, contact with the components or
the oil can cause serious injury. Allow sufficient time for the system to cool prior to performing service.
• Never allow any part of your body to contact the engine or compressor components until the system has
cooled sufficiently.

BEFORE YOU START
Switch off the engine.
Ensure components have sufficiently cooled.
Ensure that the system is completely depressurized.
CONNECTING THE HOSES
When routing hoses, ensure cap plugs are installed so that
contaminants do not get in the line. Take care when routing hoses,
as a hose failure may damage the compressor and/or cause injury.
All hoses, tubes and wires that are installed, rerouted or shifted
during the installation must be secured so that they do not contact
any hot, sharp or moving parts. Use rubber coated P-clips wherever
possible. Follow the routing suggestions in this manual and cover all
hoses with plastic loom.
PUSH-TO-CONNECT FITTINGS
Firmly push the tube into the fitting so that it fully seats in the fitting.
Slide the collet out, away from the body of the fitting to lock the tubing in place.
Ensure the tube does not have any ‘play’ to prevent the O-ring from wearing.
Figure 1 - Push-To-Connect Fittings
Cut the tube square. Do not use side
cutters as they will deform the tube
Slide the collet out once the
tube is fully inserted

RETROFIT INSTRUCTIONS
Identify the two outlets shown in Figure 2. Remove these two
hoses from the manifold while temporarily covering the hose
ends so that no debris can enter the system.
Remove the two quick connect fittings from the manifold and
clean the female threads if required.
Apply Loctite 567 (thread sealant) to the two supplied plugs (P/N:
4300076) and install them in location where the push-to-connect
fittings were removed.
Note the the location of the hoses indicated in figure 6 for connection
later in the instruction.
Remove all hoses from the inlet control valve.
Cover the hoses and open ports to ensure no debris can get inside
the system.

Remove the quick connect fitting from the regulated pressure
connection on the inlet control valve. See Figure 4.
Apply Loctite 567 (thread sealant) to the threads and install
the supplied muffler assembly into this port with the muffler
pointing towards the left-hand side of the inlet valve. See
Figure 5.
Remove any coverings from the inlet valve and compressor which were temporarily installed.
Remove the PTFE pressure signal line. Install the new line (Figure 7 and Table 1, hose #4) into the quick
connect fitting in muffler assembly on the inlet control valve (Figure 5) and route directly into the solenoid valve.
With the existing hoses marked, replace all other PTFE hoses supplied with the kit. (Figure 7 and Table 1,
hoses #3, #7, and #11).
See Figure 6 for complete system connection diagram. Ensure all hoses that were removed are re-installed
free of any moving or hot parts. Ensure all connections are tight.
