Section 2 - Installation
A - Handling
The CPVS Compressor must always be handled with care. It may
be lifted either with a forklift truck or by means of a travelling
crane. In the latter case, precautions must be taken so as not to
damage the unit's cowling.
B - Room
The CPVS is designed to operate in a frost-free environment,
supplied with air at a temperature of no more than 104 °F. The
premises must be well-aired and as close as possible to the place
where the compressed air is used. A space must be left around the
unit, for cleaning and maintenance purposes. It is very important
for the compressor to have an abundant supply of fresh air.
(see page 2).
If operating the compressor causes the ambient temperature to
rise above 104 °F, the warm air leaving the radiator must be
discharge outside.
COMMENT
When the atmosphere is contaminated by organic or mineral dust or
by corrosive chemical emanations the following precautions must be
taken:
1. Provide another air inlet as close as possible to the
compressor suction.
2. Use an additional filter. (see options Section 5), on
the machine's ventilation intakes.
Installation with heat dispersion sleeve
If the operation of the compressor increases the ambient
temperature above 104 °F, it is necessary to discharge the hot air
leaving the radiator to the exterior by means of the sleeve.

Make sure that no outside air, especially if humid, can be fed
back into the machine and damage electric and electronic
components or rust metal parts.
The maximum admissible pressure loss of the sleeve should not
exceed 30 Pa (0.12 in CE). In case of higher value, provide an
additional ventilation (mechanical extractor) with a flow
equivalent to that of the machine.
C - Assembly
Put the unit on a stable surface. The CPVS does not need
foundations. Any flat surface that can support its weight will be
sufficient (industrial floor).
D - Air discharge piping
The diameter of the air discharge pipe must be at least
2"NPT.Current legislation requires that a valve which is lockable
in the closed position be installed at the air box outlet, connected
to the compressor by a union and flexible line to allow it to be
cut off during maintenance.
E - Condensate drain pipes
A separator with automatic solenoid valve drain is provided
inside the set ( see Section 5-K) to remove the condensate at
the final cooler outlet and stop the compressor pipe condensate
return lines. Connect the discharge pipe to a condensate
manifold.(see B Section 1)
