How to test system
The below instructions give a general guide to cabin sealing, testing and commissioning BreatheSafe High Pressure HEPA Filtration units.
INPRESS
1. Inspect the cabin and ensure all cover panels are in place and any holes are sealed with grommets, sealer, fit new door seals for used equipment, etc.
2. Sitting inside the cabin with the door open, turn on the ignition to power up the unit.
3. The pressuriser fan should power up to full speed, and the monitor should indicate 0 Pa (allow ± 2 pascals wind gusts).
4. With the ignition on, close all doors and windows. If the cabin is adequately sealed, the monitor should indicate the set pressure of approximately 50 Pa or whichever preset has been chosen.
5. Once a pressure of approximately 50 Pa is confirmed, hold the down arrow button for approximately 10 seconds to run the fan speed at max speed. The display will indicate “MAX FAN SPEED” before showing the maximum cabin pressure.
6. The cabin pressure should be above 250 Pa. The minimum is 250 Pa tested with a new HEPA filter. A result of 500 Pais ideal.
7. If the above pressure is not achieved, leave the unit on full speed and investigate for external leaks outside the cabin: e.g., A/C outlets, drains, window & door seals, locks & hinges, etc.
8. If necessary, with the ignition on, controller on ‘MAX FAN SPEED’, A/C blower OFF and all doors and windows closed, set off a smoke emitter inside the cabin (SWP attached).
9. Locate any air leaks around the cabin and re-test. If silicone sealant or similar is used, allow it to dry before retesting, as even slamming the door could push the seal back out.
10. Continue the sealing and testing procedure as above until a satisfactory outcome is achieved. Fill out the form and attach photo evidence to register for warranty.
