Section 2 - Installation
A - Handling
The CP Compressors 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 canopy.
B - Room
The CP Compressors is designed to operate in a frost-free
environment, supplied with air at a temperature lower than 104°F.
The premises must be well-ventilated 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 cooler 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 intake as close as possible to the suction
source of the compressor (this recommendation applies if
the only room available is excessively humid).
2. Use an additional filter for the unit's air supply
(See Options Section).
C - Assembly
Put the unit on a stable surface. The CP Compressors 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 piping for the air network must at least be
equal to 1" NPT of the gas piping. Current legislation requires
the installation of a valve which can be locked in a closed posi-
tion at the outlet of the compressor and connected to the
compressor by a pipe union or flexible hose so as to isolate it
during servicing.
E - Electric cabling
Each CP Compressors supplied is cabled for 208V/60Hz, 230V/
60Hz, 460V/60Hz.
NEVER OPERATE THE CP COMPRESSORS ON A
VOLTAGE OTHER DIFFERENT THAN SHOWN ON
THE ELECTRIC CABINET.
The electric current supply to the CP Compressors must comply
with the following table :

SAFETY REGULATIONS
It should be remembered that safety regulations require :
• An earth socket to be used.
• A manual isolating switch, cutting all three phases ; this switch
must be clearly visible near the CP Compressors unit.
• The electric current must be cut whenever maintenance work is
carried out on the machine.
