INTRODUCTION
SITALI SF 150 is a single alternate flow decentralized (single point) residential heat recovery unit, also called «push&pull»
unit, designed to ensure adequate ventilation in enclosed environments without energy losses.
It is recommended that two units are installed in a pair: when one unit is pulling, the other is pushing.
The pair of units can be installed in the same room or in different rooms (i.e. living-room and bedroom). The unit is suitable
for installation on an outside wall.
The unit should operate continuously, and only stopped for maintenance or service.
When heat exchange is not useful (for example in mid-seasons when indoor and outdoor temperatures are similar), or
when heat exchange is not recommended (for example with the option "summer free cooling"), it is recommended to set
6
the unit in "extract-only" or "intake-only" mode and NOT to switch it off.
