INSTALLATION - continued
1. General Consideration Mounting the Compressor Unit
The starting point for the installation is a quick overview of the requirements. Some of these points will
be dealt with in more detail further on in this text. Things that should be considered now are as follows.
1. The unit should be installed in a well-ventilated area.
2. The unit will need to be installed level and any variation in the frame to be supported via washers
for spacers and properly secured to the vehicle by means of 5.8 grade fasteners.
3. In installation, the unit should be orientated s that the sight level glass for oil level can be
checked easily.
4. It should also allow to be serviced the unit easily without having to disconnect lines or remove
and reposition the unit.
5. The unit should be protected from excessive exposure to the elements and possible incidental
damage from other operations.
6. The unit should be installed in an area away from heat sources such as engines, exhaust
systems or other components that generate heat.
7. The unit should not be installed in a location where it will be exposed to high contamination
levels or combustible gases.
8. The engine exhaust should be routed away from the compressor unit. The engine exhaust
should be in an area where the exhaust CANNOT be filled up with rain (an exhaust flapper is
fitted to the exhaust) however the exhaust must not face directly down to the ground.
2. Mounting of Compressor Unit considering Ventilation
It is not possible to make absolute recommendations regarding ventilation because of the widely
differing circumstances that are possible. Duty cycle, ambient temperature and enclosure shape are
some of the important variables. Ideal ventilation will provide good airflow through the unit with no
restrictions there are two ways in which the SMAC compressor can be mounted.
1. Top or Deck Mounting
This is the preferred mounting location. Placing the unit in an area where there are no restrictions on
the intake of fresh air and exhausting of hot air and exhaust gases. This provides the best cooling and
ensures reliability and life for the compressor / diesel engine driven unit.
2. Enclosed Mounting
It is important that discussion occurs between the manufacturer and the person installing the unit when
it is to be placed in an enclosed area. Ventilation is one of the most important things to consider when
looking at the installation of a compressor/diesel engine driven unit in an enclosed area. It is important
that the air intake to the compressor and the engine exhaust are located outside of the enclosed space.
The unit generates a considerable amount of heat when running. Proper ventilation is vital for ideal
operation and to avoid damage to components. Ensure there is a minimum of 10" (250 mm) clearance
between cooler grills on SMAC and any other components mounted on the vehicle. It is strongly
recommended that the installation is tested if the unit is installed in an area considered to be enclosed
mounting. The following is a method suggested for testing.
2.1 It is best to test the installation at the hottest expected ambient temperature.
