Dear Customer,
Thank you for choosing the Rainbow 72 R ventilation and air filtration system for
installation in your house. This system saves lives.
For your safety, we recommend that you read this guide carefully. Keep the guide in a
suitable place so that it will be available and accessible in the event of an emergency.
It is recommended to practice operating the system from time to time without remov-
ing the filter sealing caps and without connecting the filter to familiarize yourself with
the operation of the system.
Safety Instructions
1. Use the system only in accordance with the instructions in this manual.
2. The system must not be used for any purpose other than for the purpose of ventilation
and filtration of a residential safety room, and protection from biological and chemical
warfare substances while staying in the safety room.
3. The system must be connected only to the standard voltage of the safe room
(100-240 VAC / 50-60 Hz). Other types of power supply may damage the system and
jeopardize its operation.
4. The system must be protected from extreme weather conditions and humidity.
5. The system should be stored out of the reach of children. Do not allow children under

Principle of system operation
When the system is operating according to the instructions, air is introduced to the room
via the air inlet valve and the NBC filter (2). The filtered air is circulated through the room
and creates an overpressure, thus preventing the entry of polluted air through crevices
or concealed openings
When the room is in a state of overpressure, the indicator vane (7) spins around. In this
state, it is possible to remain in the room without the personal NBC masks (on condition
that the room is not contaminated by NBC before operating the system). Overpressure
created in the room is not harmful to humans and pets.
The following illustration displays the parts of the system and their location in a
residential safety room:
