Section III - Installation

Shipping Supports

Shipping supports are used to secure
the motor and airend during shipping to
prevent damage to the motor, airend,
reservoir and the connections to these
components.
The shipping supports are painted red and
are located near the motor support.

Piping Connections

Never join pipes or fi ttings by soldering.
Lead-tin solders have low strength, a
low creep limit, and may, depending on
the alloy, start melting at 360°F. Silver
soldering and hard soldering are forms of
brazing and should not be confused with
lead-tin soldering. Never use plastic, PVC,
ABS pipe or rubber hose in a compressed
air system.

Piping Fit-up

Care must be taken to avoid assembling
the piping in a strain with the compressor.

Pressure Vessels

Air receiver tanks should be in accordance
with ASME Boiler and Pressure Vessel
Code Section VIII.

NOTICE!
Once the compressor has been located
and secured at the installation site, the
shipping supports must be removed
before operating the unit.
To remove the shipping supports, remove
the screws attaching them to the airend
and to the base.
Piping should line up without having
to be sprung or twisted into position.
Adequate expansion loops or bends
should be installed to prevent undue
stress at the compressor resulting from the
changes between hot and cold conditions.
Pipe supports should be mounted
independently of the compressor and
anchored, as necessary, to limit vibration
and prevent expansion strains. Piping
should never be of smaller size than the
connection on the compressor unit.
CAUTION!
ASME coded pressure vessels must
not be modified, welded, repaired,
reworked or subjected to operating
conditions outside the nameplate
ratings. Such actions will negate code
status, affect insurance status and
may cause death, serious injury and
property damage.
