Notes:
1 Weight approximate: 2042 kg (4500 lbs)
2 Cooling air flow: 241 m
3
/min – 8500 CFM.
3 Pipe condensate drain lines separately to an open
drain due to difference in drain pressures. Check local
regulations.
4 Lube oil fill quantity: 53 litres (14 US gallons)
approximately.
5 All dimensions in millimeters (inches).
6 Tolerance on all dimensions:
±
6 mm (
±
.25 inch).
7 Recommended clearance on three sides 915mm
(36 inches). Side with electrical box 1067mm (42
inches) or minimum as required by latest national
electrical code or applicable local codes.
8 External piping shall not exert any unresolved
moments or forces on unit. Use pipe size as large or
larger at discharge location.
9 There should be no plastic or PVC piping attached
to this unit or used for any lines downstream.
10 Remove the isolation mount restraints before the
initial start. The two restraints can be discarded.
11 Field installed ducting to and from compressor
cannot add more than 6mm (0.25 inches) of water total
air resistance. Gear box breather must be piped
external.
12 Unit has internal discharge check valve. External
check valve not required. Isolation valve is required
within 915mm (36 inches) of the compressor discharge.
13 Compressor should be bolted to the floor with four
M10 (0.38 inch) bolts located as shown. Seal base to
floor with cork or rubber.
14 Do not pipe into a common header with a
reciprocating compressor, unless reciprocating
compressor utilizes a discharge pulsation dampener.
15
Denotes center of gravity.
16 Sizing of electrical components not supplied by
Ingersoll–Rand is the responsibility of the customer and
should be done in accordance with the information on
the compressor data plate, National and local electrical
codes.
17 A 63mm (2.48 inches) diameter electrical power
inlet connection hole is provided in side of electrical box
as indicated. Size and positioning can be changed by
customer in accordance with note 16.
18 When installed indoors or under a shelter, the
cooling air inlet or exhaust must be ducted away from
the unit to prevent recirculation of hot exhaust air.
19 The 550–575 volt option requires an externally
mounted transformer. The Transformer General
Arrangement is I–R part number 22585103.
The 200–230 volt option requires an externally
mounted transformer. The Transformer General
Arrangement is I–R part number 22637581.
