10. Piping
CRM-V series Mistresas do not use a duct hose or drain tube, so neither
needs to be connected to the unit.
Connect the Mistresa directly to the machine/equipment.
(1)
Duct hose material
Because the life of the duct hose will vary according to the type of mist
being sucked in, the use of an oil-resistant duct hose is recommended.
(2)
Intake duct piping
①
A flexible duct (optional item) should be used to facilitate easy duct
maintenance and vibration resistance.
②
The duct should be somewhat longer than strictly necessary (slight
length surplus), but it must not sag when connected.
③
Use the duct companion flange (accessory item) to facilitate easy
connection.
