Troubleshooting

Problem
No air flow
Little air flow
Audible alarm activating
The BVX-200 filter-block alarm is factory calibrated to a specific temperature setting and will, for most
users, require no adjustment. However, users in warmer climates may need to adjust the BVX-200
temperature setting to prevent false alarms.
1. Assemble the BVX-200 as per the User Guide. Both the remote switch the main power switch
should be in the 'Off' position.
2. Switch On the main unit and press the remote switch. The remote switch LED will light when
powered. The unit will run and you will hear the alarm sound momentarily but then stop while the
motor continues to run. Allow the motor to run for at least 10 minutes to attain normal operating
temperature.
3. With one inlet port already blocked, place a block plate with a 6mm Ø hole over the other air inlet
and listen for the alarm tone. If heard, go to next step; if not, remove the plastic blanking-plug and
turn the potentiometer counterclockwise until the alarm tone is heard.
4. Replace the 6mm Ø hole blank with a 15mm Ø one. If the alarm still sounds, gently adjust the
potentiometer by turning screwdriver clockwise until the alarm can no longer be heard. Refit the
blanking plug once the correct setting is obtained.
To make your own block-plates:
A standard CD has a 15mm Ø hole at its center.
A paper hole-punch may be used on stiff card to make a hole that is approximately 6mm.
