CAUTION

When installing a fan, ensure the proper protective
devices are used to protect personnel from
moving parts and other hazards. A complete
line of protective accessories are available from
Greenheck including belt guards, shaft guards, and
electrical disconnects.

Electrical Disconnects

All fan motors should have disconnects located in
close visual proximity to turn off electrical service.
Service disconnects shall be locked out when
maintenance is being performed.

Moving Parts

All moving parts must have guards to protect
personnel. Refer to local codes for requirements
as to the number, type and design. Fully secure fan
wheel before performing any maintenance. The fan
wheel may start “free wheeling” even if all electrical
power has been disconnected. Before the initial
start-up or any restart, check the belt and shaft
guards and the access doors to ensure that they
are installed and secure.

Machined parts coated with rust preventive should be

restored to good condition promptly if signs of rust occur.

Immediately remove the original rust preventive coating

with petroleum solvent and clean with lint-free cloths.

Polish any remaining rust from surface with crocus cloth

or fine emery paper and oil. Do not destroy the continuity

of the surfaces. Wipe clean thoroughly with Tectyl

506

(Ashland Inc.) or the equivalent. For hard to reach internal

surfaces or for occasional use, consider using Tectyl

511M Rust Preventive or WD-40

or the equivalent.
