3.6.2
Supply line inside diameter - Pipes and hoses should be sized to accommodate
the hoist’s airflow requirements. The inside diameter for the pipe section feeding the hoist should be
12.7mm (½”) or larger and for air supply hose the inside diameter should be 9.5mm (3/8”) inch or larger.
3.6.3
Hoses - The connection from the air supply system piping to the hoist must be
made with a flexible pressure hose. Due to normal line losses in air supply lines:
Do not use hose smaller than specified in Section 3.6.2, and
Limit the length of the hose to that specified in Figure 3-3.
If your application exceeds these requirements consult factory.

Fittings - Important considerations regarding fittings in the hoist’s air supply
include:
When connecting air supply components, remove all dirt or debris from the connecting surfaces of
the hoses, pipes, fittings, or threaded fasteners to prevent contaminants from entering the hoist.
Keep airflow restrictions such as quick disconnect fittings, bends, elbows, and adapters to a
minimum.
3.6.5
Before connecting the hoist to its air supply line, perform the proper draining and
purging procedures to prevent contaminants or moisture from entering the hoist.
