Ingersoll Rand will accept no liability or warranty
claims if your installation includes any modifications
or additions to the blower without the prior written
approval of Ingersoll Rand, or if the blower is incorrectly
installed.
3.1 Installation safety
WARNING
Obey the safety instructions listed below and take note
of appropriate precautions when you install the blower.
A suitably trained and supervised technician must install
the blower.
Ensure that debris and dust does not get into the blower or
the system pipelines when you install the blower.
Check that all of the required components and tools are
available and of the correct type before you start to install
the blower.
Use suitable new gaskets/seals to connect the blower into
your system. Do not re-use old gaskets/seals.
If you will fit the blower into an existing system, disconnect
the power from the drive system before you start
installation, so that the drive system cannot be operated
accidentally.
3.2 System design and safety
WARNING
Ensure that the maximum differential pressure across
the blower specified in section 2.2 cannot be exceeded.
If it is, the drive will trip and the blower will stop. Obey
the safety instructions listed below when you design
and build your system:
3.2.1 General requirements
Your system must be suitably designed for correct operation
of the blower.
Note that:
You must design a suitable pipeline to fit the blower inlet/
outlet connections. refer to Section 2.8 and to Figures 3
and 4 for the dimensions of the blower connections.
Your system design must ensure that, when the blower
is in its final operating location, you can see the oil-level
sight-glasses and can access the oil filler and drain plugs.
Your system must incorporate a suitable mounting
platform: see Section 3.4 for more details.
The blower must be sufficiently level for correct operation:
see Section 3.4 for more details.
There must be at least 150 mm (6 inches) of free space
around the blower, for adequate cooling-air circulation.

The gases which enter the blower must not contain solid
particulates larger than 25 μm (9.84 x 10
-5
inch) in size and
must not contain more than 200 mg/m3 (1.37 x 10
-5
lb/ft
3
)
of dust. Incorporate suitable filters to prevent the ingress
of solids into the blower.
The temperature of the gases which enter the blower must
not exceed the temperature rating of the blower.
3.2.2 System safety
Your system design must ensure that the blower cannot
be operated with the inlet or discharge (outlet) pipelines
obstructed.
Ensure that the blower cannot operate with the incorrect
direction of rotation (see Section 3.7).
We also recommend that your system incorporates an
emergency stop facility which, once activated, must be
manually reset before the blower can be operated again.
Your system must incorporate non-return valves (check
valves), to prevent reverse rotation of the blower when it is
switched off.
Your system must incorporate a pressure relief valve in the
outlet pipeline (for pressure operation) and/or incorporate
a vacuum relief valve in the inlet pipeline (for vacuum
operation), to ensure that the design capability of the
blower cannot be exceeded during operation. The relief
valve(s) must be suitably rated/sized for the performance
of the blower.
We recommend that you incorporate silencers, to
attenuate the pulsations in the inlet/outlet gas streams.
If required, install your own acoustic enclosure around
the blower or ensure that people wear suitable protective
equipment (such as ear defenders) when they are close
to the operating blower (See section 2.4). If you install an
acoustic enclosure, ensure that there is sufficient space for
cooling-air flow around the blower. See above
Your design must ensure that people are protected from
accidental contact with the blower or the outlet pipelines.
During blower operation, the temperature of the blower
and the outlet pipelines will be above 70 °C (158 °F). If
necessary, fit suitable guards.
Your design must ensure that materials or substances
which are flammable at temperatures of 70 °C (158 °F) or
above are not close to, or in contact with, the hot blower or
outlet pipelines.
If you pump/compress flammable or toxic gases, you must
take suitable precautions to prevent the discharge of the
gases to the surrounding atmosphere.
Note:
Filters, pressure/vacuum relief valves, non-return (check)
valves, acoustic enclosures and silencers are available from
Ingersoll Rand
: contact your supplier or
Ingersoll Rand
for
advice.
