INSTALLATION IN PLACE WITH RECIRCULATED AIR
INSTALLATION IN PLACE WITH EXHAUST AIR
INSTALLATION IN PLACE WITH OUTSIDE AIR
The air exiting the product can reach temperatures of 5-10°C less than that entering.
If adequate ventilation or addition of heat is not provided for, the temperature in the
installation room may drop considerably .
If operation with expulsion to the outside of air treated by the
heat pump is foreseen, a ventilation system is required in order to
prevent a negative pressure in the room .
The connection to the outside must be made with suitable non-
flammable pipes .
The total equivalent length of the exhaust piping, including
recommended exhaust grille, must not exceed 10 m
Additional heating by means of heating elements may be required .
The connection to the outside must be made with suitable non-
flammable pipes . The total equivalent length of the exhaust piping
plus the delivery piping, including grilles, must not exceed 10 m .
The table gives the characteristic data of 150 mm diam . commercial ducting components
Notes:
Make sure the pipes are connected and securely fixed to the product, to prevent accidental disconnection .
Do not use external grilles that involve high pressure losses, such as anti-insect grids . The grilles used must allow a
good air flow, and the distance between the air inlet and outlet must not be less than 50 cm .
