RS 20 Compliant Dual HEPA System

Product Information: RS 20 Compliant Dual HEPA

The RS 20 Compliant Dual HEPA is a filtration system designed to
improve air quality in cabins. It is equipped with dual HEPA
filters that effectively remove airborne contaminants. The system
is compatible with various applications and may require some
fabrication of metal components for proper fitment.

Key Features:

Dual HEPA filters for enhanced air purification
Easy installation with sealing measures
Secure filter and grille with knob
Controller for adjustable settings
Serviceable filtration unit
Compatible with OEM pressuriser circuit

Product Usage Instructions

Ensure all OEM glass/panels are in place and door seals are in
good condition.
Clean the cabin and vacuum it with a HEPA vacuum before
installation.
If applicable, remove the seat and internal panels to access
potential air leakage points or run wiring looms.
Remove the OEM fresh air filter or pressuriser and discard
it.
Apply sealing measures, such as adhesive foam tape, to
accessible leak points and open glands.
Remove the OEM recirculation filter cover and discard the OEM
filter assembly.
If fitted, remove the fresh air flap entirely.
Sikaflex the new BreatheSafe HEPA return air backing plate into
place, making modifications if necessary.
Secure the filter and grille using the provided knob. Use
masking tape to temporarily hold them in place while the sealant
sets.
Refit the inner console assembly and ensure all bolts are in
place through the floor to avoid leakage.
Solidly mount the controller in a suitable location using bolts
or other fixing methods.
Affix the filtration unit in the desired location, considering
serviceability. Custom mount plates may be required in certain
applications, but drilling into the cabin structure is not
recommended.
Secure the ducting with brackets and stauff clamps,
manufacturing or adapting as necessary.
Ensure the filter can be easily removed and the system is
accessible for servicing. The filtration unit must be in the
correct orientation.
Locate the OEM fresh air filter inlet, remove the cover, and
discard the OEM filter.
Fit an inlet spigot or custom duct to introduce the HEPA
filtered air into the HVAC system. Engineering may be required for
proper fitment.
Follow the pressuriser wiring connections as per the provided
diagram. Upgrade the OEM pressuriser circuit fuse and use the
existing pressuriser circuit to power the BreatheSafe system. If
necessary, supply a new circuit with a 25A fused supply live from
ignition, ensuring correct voltage.
Route Pipe A pressure sense port to atmosphere outside of the
cabin with the external end facing downward to avoid dust
blockage.
To carry out a successful commissioning procedure, follow these
steps:
1. Press the Settings icon on the controller.
2. Press the System Check box.
3. Record or photograph the cabin efficiency result (Max
  Fan).
4. Complete the commissioning form online at breathe-safe.com.
For commissioning pressurised cabins with BreatheSafe units
fitted, ensure the cabin is clean with a HEPA vacuum.

GENERIC INSTALL GUIDE
RS 20 COMPLIANT DUAL HEPA
Controlled Document: M0021 Issue Date: 25/10/22 Revision: 2

Installation Instructions This is a generic guide referencing fitment of the Dual HEPA system. Some fabrication of metal components may be required toadapt the kit in certain applications.
Ensure all OEM glass / panels are inplace & door seals are in good condition. Cabin needs to be clean & HEPA vacuumed prior to install.
If applicable remove seat & internal panels to access potential air leakage points / run any wiring looms. Remove OEM Fresh air filter orpressuriser & discard.
Apply sealing measures to accessible leak points & open glands. E.g., adhesive foam tape.
Remove OEM recirculation filter cover

Discard OEM filter assy.
Remove fresh air flap entirely (if fitted).
Sikaflex new BreatheSafe HEPA return air backing plate into place. *Modification required in certain applications.
Secure filter & grille using knob. (Use masking take to hold in place temporarily while sealant sets).
Refit inner console assy. Ensure all bolts are in place through floor to avoid leakage.

Solid mount controller in chosen suitable location by means of bolting / fixing in place.
*As per examples. Ensure easily visible & not obstructing operator controls.
Affix filtration unit in desired location taking serviceability into account. Custom mount plates may be required in certain applications. *BreatheSafe recommends not drilling any part of the cabin structure.
Secure ducting with brackets, stauff clamps. *Manufacture/ adapt as necessary.
Ensure filter can be removed & system is easily accessible for servicing. Filtration unit must be correct orientation.

Locate the OEM fresh air filter inlet.
Remove cover & discard OEM filter.
Fit an inlet spigot or custom duct to introduce the HEPA filtered air into the HVAC.
Example of ducting into OEM 3-inch fresh air inlet. *Some engineering may be required.

Follow pressuriser wiring connections as per the diagram.Upgrade the OEM pressuriser circuit fuse & use existing pressuriser circuit to power the BreatheSafe system. *Where necessary supply a new circuit. 25A fused supply livefrom ignition ensuring correct voltage.
Pipe A pressure sense port to route to atmosphere (outside ofcabin). Face external end downward to avoid dust blocking thetube.
*Based on touch screen controller.

Carrying out a successful commissioning procedure: Begin full speed test mode as per below instruction. Use hands to feel externally of the cabin to detect pressure leaks and apply seal measures until 250 pascals positive cabin pressure result is achieved or exceeded. The system will not work efficiently if the cabin sealing process is not delivered correctly and not covered by warranty.

COMMISSIONING PRESSURISED CABINS WITH BREATHESAFE INPRESS UNITS FITTED

The below instructions give a general guide to cabin sealing, testing and commissioning BreatheSafe variable speed pressurisation units (Clean cabin with HEPA vacuum).

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 pressure (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 (Pascals), or whichever pre-set has been chosen. 5. Once a pressure of approximately 50 Pa is confirmed, hold down the 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. INPRESS TL with Auto Pressure Control (5400 RPM) the cabin pressure should be above 250 Pa (the minimum is 250 pascals tested with a new TLF700EN HEPA filter). A result of 500 pascals is 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 record below and attach photo evidence of maximum pressure result and NANOZEN Real-time Dust Monitoring result to register for warranty.
