Accessing The Internal Components - Accurex XRRS Installation, Operation And Maintenance Manual

Accessing the Internal Components

Moving the unit between 'operating' and 'service'
positions.
All XRRS models have been configured as a stand
alone unit mounted to a wall plate. As such, the unit
may easily be tilted down into a service position, giving
you access to the electronics and extinguisher tank, or
be removed completely for maintenance and cleaning.
Provisions have been made to facilitate easy removal
including a minimal amount of fasteners and modular
electrical connections.
To place the unit in the service position, a few simple
steps are required. Be sure to wear safety glasses at all
times during this process:
1. Shut the unit off with the power switch on the front of
the hood.
2. Remove the grease tray and the grease entrapment
filter.
3. For non-ducted installation, loosen and remove
the thumb nuts that are on the rear inside wall of fan
housing compartment.
On ducted installations, remove the two thumb nuts
located at the top inside near the fan intake. Slowly
lower the unit.
4. The unit will now freely pivot downward to a stop
position. A safety cable is provided to prevent the
unit from falling or lowering too far.
5. Place safety pin in the tank valve to avoid accidental
discharge.
With the unit in this position, basic servicing and
cleaning may be performed, including servicing the
extinguisher tank assembly.
To move the unit back to the operating position, simply
reverse the process as outlined above.

CAUTION
• Be careful while working with the unit in the service
position. Release of the cable system or applying
force to the tank valve assembly may cause
discharge of the tank. The high pressure discharge
has the potential to cause skin or eye damage and
injury!
• An electrical shock hazard is present at the
electrical compartment whenever there is power to
the hood. Use caution when working around this
device while the unit has power.
