2.0 General Overview
2.1
The product incorporates a Heat Exchanger that recovers the heat energy from the "extract air" that would
normally be lost with other ventilation systems. It does this using minimal power consumption as the product
uses EC low energy motors.
2.1.1
Depending on the way your ComfoAir Compact unit has been installed, the specific operation may vary.
The unit has two speeds available:
I
Low Speed:
Operating on a continual basis
II
High Speed:
Activating manually using our ZGS2 switch or via “switch-live”
ZGS2 switch markings: Low (I) & High (II) operation
Note: Other manufacturers switches may show different markings, or your unit may be connected to
a Building Management System (BMS).
2.1.2
To maintain good indoor air quality within the dwelling it is important that the ventilation system remains in
operation at all times unless powered down periodically for maintenance/repair.
2.1.3
Warning: This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of experience
and knowledge if they have been given supervision or instruction concerning use of
the appliance in a safe way and understand the hazards involved. Children shall not
play with the appliance.
2.1.4
Siting Notes: Where an open-flued oil or gas-fuelled appliance is installed in the
kitchen, extract ventilation can cause the spillage of flue gases. Care must be taken
to ensure ventilation is reduced appropriately, as set out in the Building Regulations.
Kitchens with solid-fuel appliances should not have extract fans fitted.
