General Electrical
A qualified electrician shall perform all electrical installations and service.
The compressor shall be properly grounded / earthed in compliance with all
applicable standards and regulations (local, state, country, federal, etc.).
Installation of this compressor shall be in compliance with all applicable
standards and regulations (local, state, country, federal, etc.).
The compressor shall have its own isolator situated adjacent to it. The fuse
protecting the circuit and the compressor shall be selected in accordance
with recognized code requirements on the basis of the data provided in the
specification sheet.
Feeder cables shall be sized to ensure that the circuit is balanced and not
overloaded by other electrical equipment. The length of wiring from a
suitable electrical feed point is critical as voltage drops may impair the
performance of the compressor.
Feeder cable connections to incoming terminals L1-L2-L3 shall be tight and
clean.
The applied voltage shall be compatible with the compressor data plate
ratings.
The control circuit transformer has different voltage tappings. Ensure that
these are set for the specific applied voltage prior to starting.
Remove the blind plate to cut a hole for incoming power connection. If it
is necessary to make a hole in the control box in a different location, care
should be taken to not allow metal shavings to enter the starter and other
electrical components within the box. If another hole is used, the original
hole shall be blocked off.
The feeder cable shall be suitably glanded in to the starter box to maintain
proper ingress protection. Fixed speed starter boxes are rated for NEMA 4
/IP65.
NOTICE
Main and fan motor insulation shall be tested by a qualified electrician
prior to initial start-up or following an extended shutdown period in
cold and damp conditions.

Integrated Dryer
Do not connect condensate drains common to other pressurized drain
lines in a closed circuit. Make sure the outflow from the condensate drains
is unimpeded. Connect the condensate piping in such a way to ensure that
sound levels are kept to a minimum during drainage.
Ensure that all condensate is disposed of in a responsible manner, in
compliance with all applicable standards and regulations (local, state,
country, federal, etc.).
The ambient air around the dryer and compressor shall not contain solid
or gaseous contaminants. All compressed and condensed gases can
generate acids or chemical products which may damage the compressor or
components inside the dryer. Take particular care with sulphur, ammonia,
chlorine and installations in marine environments.
Environmental Limits
The standard compressor package is designed for the following conditions:
•
Indoors only.
•
Area not considered to be a high dust area.
•
Ambient temperature range 2 to 46 °C (35-115 °F).
Ingersoll Rand offers the following options for fixed speed compressors that
extend the environmental limits:
•
Outdoor modification.
•
Freeze protection (US & Canada only) -23 to 46°C / -10 to 115°F at sea
level.
•
Frost protection (Global) -10 to 46°C / 14 to 115°F at sea level.
•
High ambient option (2 to 55 °C / 35 to 131 °F) at sea level.
•
High dust air filter.
•
High dust package filter.
