Mounting

The Multi Direct Mounting system provides a total of 12 mounting points (four on the left, right and bottom sides). Each mounting point has an M12 x 1.75 mm threaded hole, providing excellent flexibility in engine mounting and bracket design.

Service valves

Low- and high-side service valves are fitted on the shut-off manifolds, and on the rear cap of the compressor.

Oil return port

An oil return fitting – 7/16-20 UNF male flare (Part No. 42203-000160) – is fitted on top of the compressor. It has a unique flow design suited to the Unicla oil separator (Part No. OS000050) and is interchangeable with the low-side service valve.

Other ports and fittings

Consistent M12 x 1.0 mm access port size. Easy interchange of blanking plugs, service valves, oil return and pressure switch fittings.

Hose ports

The suction port is located on top of the compressor and the discharge port can be taken from either the left or right side. Both ports are fitted with a shut-off manifold assembly with back seating capability via stem valves.
