If the unit is not being used immediately after installation, it is recommended that the unit is run at full speed for at least 1
hour every 3 months so that any condensates that have infiltrated can evaporate and the roller bearings can move.
11.1.3 - Cooling coil
Make sure that the chilled water supply pipes are insulated.
Moderately tighten the coil supply connections to avoid damaging the manifolds
The coil is regulated by a two-way or three-way valve equipped with a 0-10V servomotor (mounted and connected)

.
The operation point can be adjusted directly via the controller. All air flow/operating pressure combinations are therefore possible with
maximum values as per the values in the table above.
