Install the tank clamps over the front of the tank and slide them toward the
centre of the tank.
Install the tank onto the tank mounts, leaving the fasteners finger tight (Figure 24):
☐
Adjust the tank in the straps, the front of the AOST should protrude
approximately 5 in – 6 in past the tank strap.
☐
Apply loctite 242 (blue) to the (×2) 3 in × 1/4 in pinch bolts and install them
into the mounting clamps.
☐
Rotate the tank so that the directional arrow on the blowdown cap, at the rear
of the tank, is pointing upward.
AOST orientation is critical. The arrow on the blowdown cap at the
rear of the tank must be pointing up to prevent compressor failure
due to oil starvation, or oil in the discharge air.
☐
Tighten the AOST mounting bolts.
VMAC recommends using a using smooth radius 90° hose crimp
fitting at the AOST discharge for best performance and exhaust
clearance
