not bind.
• Inspect dampers (if included) for free operation of all
moving parts.
• Remove mounting brackets from packing insert & install
mounting brackets (Gemini 100 only).
• Remove shipping tape.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Rotating Parts & Electrical Shock Hazard:
Fans should be installed and serviced by qualified person-
nel only.
Disconnect electric power before working on unit (prior to
removal of guards or entry into access doors).
Follow proper lockout/tagout procedures to ensure the unit
cannot be energized while being installed or serviced.
A disconnect switch should be placed near the fan, so
power can be swiftly turned off in case of an emergency.
This will also allow maintenance personnel to have com-
plete control of the power source.
Grounding is required. All field-installed wiring must be
completed by qualified personnel. All field installed wiring
must comply with National Electric Code (NFPA 70) and all
applicable local codes.
Fans and blowers create pressure at the discharge and
vacuum at the inlet. This may cause objects to get pulled
into the unit and objects to be propelled rapidly from the
discharge. The discharge should always be directed in a
safe direction and inlets should not be left unguarded. Any
object pulled into the inlet will become a projectile capable
of causing serious injury or death.
When air is allowed to move through a non-powered fan,
the impeller can rotate. This is referred to as windmilling.
This unexpected rotation of components can cause a haz-
ardous condition. Impellers should be blocked in position
or air passages blocked to prevent draft prior to working
on fans.
Friction and power loss inside rotating components can
cause them to be a potential burn hazard. All components
Gemini 100 should be approached with caution and/or allowed to cool
before contacting them for maintenance.
Under certain lighting conditions, rotating components
may appear stationary. Components should be verified to
be stationary in a safe manner, before they come into con-
tact with personnel, tools or clothing.
Failure to follow these instructions could result in death or
serious injury.
