REMOVAL AND REPLACEMENT OF COMPONENTS
ELECTRICAL LOCKOUT/TAGOUT
PROCEDURE
Before performing any service that
involves electrical connection or disconnection and/or
exposure to electrical components, always follow the
Electrical LOCKOUT/TAGOUT Procedure. Disconnect
all circuits. Failure to comply can cause property
damage, injury or death.
The Electrical LOCKOUT/TAGOUT Procedure is used to
protect personnel working on an electrical appliance. Before
performing any maintenance or service that requires exposure
to electrical components, follow these steps:
1. In electrical box, place appliance circuit breaker into
OFF position.
2. Place a lock or other device on electrical box cover to
prevent someone from placing circuit breaker ON.
3. Place a tag on electrical box cover to indicate that
appliance has been disconnected for service and
power should not be restored until tag is removed by
maintenance personnel.
4. Disconnect appliance power cord from electrical outlet.
5. Place a tag on the cord to indicate that unit has been
disconnected for service and power should not be restored
until tag is removed by maintenance personnel.

General Service Notes
• This unit uses water trays for humidity control. Remove
any water that might be present in the trays before
attempting service of any kind.
• During its installation, this unit is required to be secured to
the building structure. There is also a Restraining Device
(a heavy, flexible metal cable) that was installed to prevent
the unit from moving beyond a certain distance in order
to prevent damage to the electrical conduit feeding it.
Most service can be accomplished without moving the
unit from its mounted position. However, if the unit is
moved during service, then these securing devices must
be reinstalled for continued protection against tip-over
and to meet other compliance regulations.
