Air connections
.
Your heat pump water heater can be fitted with ducting accessories that are not supplied with the water
heater.
If the volume of the room in which the thermodynamic water heater is installed is insufficient, it can be
connected to 160 diameter air ducts. If the air ducts are not insulated, condensation may appear on them
during operation.
Therefore, it is essential to choose insulated air ducts.
Poor ducting (crushed ducts, ducts that are too short or too many corners, etc.) may have a negative
impact on performance.
Therefore, you are strongly advised to use rigid ducts.
When connected to ducts, the regulation must be adjusted accordingly (see Setting the
regulation
section, page 15
).
The total head loss in the ducts and accessories of the air inlet and outlet must not exceed
150 Pa. The head losses must be calculated using the measuring tools supplied by the
manufacturer and on the basis of the proposed ducting accessories.
