Step 3. Select Suitable Location

WARNING: Lifting hazard
The compressor is heavy. Ensure that proper lifting
equipment is available to unload and move compressor
to installation site.
Location Criteria:
Where no flammable vapors, dusts, and gases

are present.
At least 15" away from walls and other objects.

Away from other heat-generating equipment.

Away from dusty/dirty conditions.

In a well illuminated area.

Where proper wire size is already, or can be

made, available.
Positioning:
The compressor should be mounted on a dry,

firm, and level surface. It must sit level and be
stabilized since it will slide or shift during
operation if not secured.
Airflow:
Provide access to adequate, clean and

unobstructed airflow for cooling and air supply.
Remember the supply air is passing through the

compressor supply hoses and tools. These can
be damaged or have a shortened life if unclean
air is present or air filter is not clean and
functioning properly.
Do not allow debris to accumulate or block

airflow.
Do not operate with a tarp, blanket, or cover

surrounding the machine, which blocks air flow.
Do not place any objects against or on top of the

unit, which can also block airflow or damage unit.
Electrical:
MUST be connected to a 230 Volt, single-phase

outlet having operating capacity of 30 amp (Model
#459231, 5 H.P.) or 40 amp (Model #459241, 7.5
H.P.).
Wiring:
Proper wire size should take into consideration

length from distribution panel.
See Step 6, "Wiring Installation" for more

information.
Ideal operating temperatures:
40 and 100F (4 and 37C).

Operating Limitations:
15F (-9C) or above 125F (52C).

If temperatures consistently drop below 32 F (0C),
install within a heated building. If this is not possible,
protect the safety/relief and drain valves from freezing.
Note: Excessive moisture is likely to occur if unit is
stored in an unheated area subject to large
temperature changes. Moisture forming in pump can
produce sludge in the oil, causing parts to wear out
prematurely. Excessive condensation on the pump
when it cools down is a sign that this may be
occurring.

Step 4. Permanent Mounting

You will permanently mount the compressor after
selecting the location in Step 3.
1. On a concrete pad or other stable mounting
platform, drill 4 holes according to the mounting
dimensions given in the diagram below. (Figure 6)
2. Unbolt the compressor feet by removing the
bolts, washers and nuts. Discard them after
removal. (Figure 7)
3. Lift and remove the compressor from the pallet
using a hoist and lifting eyes provided.
4. Situate unit in chosen location and bolt in place.
(Use 7/16" bolts and washers. Make sure bolts
are long enough to provide a good anchor
point.) Bolt it in place to prevent unit from
