Duct Connection; Hydraulic Connection - Lennox MiniAir 10 Installation, Operating And Maintenance Manual

4.7 Duct connection

IMPORTANT: IT IS IMPORTANT NOT TO PLACE
IN OPERATION THE UNIT IF THE FAN OUTLETS
ARE NOT DUCTED OR NOT PROTECTED BY A
SAFETY NET ADHERING WITH REGULATION
UNI 9219 OR SUCCESSIVE.

The Ducts must be the correct dimension based on the functions of system and the air diffusion characteristics
of the unit fans. A mistaken calculation of the ducting will cause power loss or the intervention of any eventual
devices present on the system.

To prevent the formation of condensation and cut down the sound level it is advised to use internally lined
Ducts.

To avoid the transmission of machine vibrations into the environment, it is advised to fit an anti-vibration joint
between the fans and Ducts. The electrical continuity must be guaranteed between the Ducts and the apparatus
via an earth cable.
4.8 Hydraulic connections

The installation and connecting of the piping is an operation that must be done correctly, otherwise it may
compromise the performance of the system. At worst it may cause irreversible damage to the machine. These
operations are to be effectuated by qualified personnel.

The MINIAIR units are supplied with "female" mounted, GAS threaded water coils.

Extreme caution must be taken during the installation operation, to avoid damage.

The tube path must be studied in such a way to not create obstacles should an eventual extraction of unit coil or
filter be required.

Water inlet and outlet must occur allowing the thermal exchange in counterflow: follow the indications found on
the WATER INLET and WATER OUTLET plate.

Supply a lower valve for the emptying of the water contained in the coil.

Fix securely the tubes to the outside of the unit, so as to avoid offloading the weight onto the coil headers.

Once the connection has been followed, fix the external rubber seals against the panel to avoid passing of air.

The lining must just rest on the panel, to avoid the risk of burning.

Supply an interception valve to isolate the coil from the rest of the circuit in case of extraordinary maintenance.

Should the installation of the apparatus occur in areas with particularly cold climates, empty the system prior to
an extended period of inutilization.
4.8.1 Condensation outlet connection

The stainless steel condensation drip tray is provided with 20 mm outlet diameter.

The system of drainage must provide an adequate trap.
 The dimensions and execution of the trap must guarantee that H  50 mm.
