Hidraulic circuit:
• Make sure that water connections are correct, water inlet (down side), water outlet (upper side).
Lennox offers this element as an option.
• Install cut off valves at inlet and outlet water connections, because of in case of repairs, the hydraulic circuit can be
independent.
• Install water inlet and water outlet connections with a differential gauge device in order to see the pressure difference
between
the outlet an inlet connections.
• At the end Install an adequate water pump, and all the necessary elements for the installation

AIR FLOW:
Airfl ow can be adjusted though the unit remote display between maximum/nominal/minimum
With “AUTO” the controller regulates the airfl ow between maximun and minimum values to assure the correct unit
operation mode.
DRAINAGE TUBE
• Use the fl exible tube connected to the drip tray as a drainage tube. Cause a siphon with this tube in order to avoid
the inlet of scents from the installation to the unit.
Install a siphon from the drainage tube of the drip tray with a difference in height of 80 mm to prevent from not evacua-
ting due to the negative pressure created by the fans. The pipe will slope down 2% to make it easier for the conden-
sates to drain off.
