Maintenance And Repair Parts; System Component Inspection - Pressura RPM10 Operation And Service Manual

Occupancy Sensor Configuration
NOTE:
1. Set the UNOCC SIG to match the occupancy indication from the switch. OPEN means the
switch will open to indicate the room is unoccupied. CLOSED means the switch will close to
indicate the room is unoccupied.

Maintenance and Repair Parts

The Model RPM10 and RPM20 PresSura Room Pressure Monitors require minimal maintenance.
Periodic inspections of system components as well as an occasional pressure sensor cleaning
are all that are needed to ensure that the PresSura monitor is operating properly.

System Component Inspection

It is recommended that the pressure sensor be periodically inspected for accumulation of
contaminants. The frequency of these inspections is dependent upon the quality of the air being
drawn across the sensor. Quite simply, if the air is dirty, the sensors require more frequent
inspection and cleaning.
Visually inspect the pressure sensor by sliding open the sensor housing door (Figure 13). The air
flow orifice should be free of obstructions. The small ceramic coated sensors protruding from the
orifice wall should be white and free of accumulated debris.
Periodically inspect the other system components for proper performance and physical signs of
excessive wear.

Occupancy switches are optional and may not be installed in your
system.
