OPERATION ALGORITHM

The motor is controlled by sending of an external control signal from 0 to 10 V to the X2 terminal block or by
the R1 internal speed controller. Control method selection is carried out by means of the SW DIP switch:
- DIP switch in IN position. The control signal is set by the R1 internal speed controller, which allows to turn the
fan on and off, smoothly adjust the speed of the fan motor (air flow) in the range from minimum to maximum
speed.
Rotations are controlled from minimum (extreme left position) to maximum (extreme right position). When
rotating clockwise, the rotations increase.
- DIP switch in EXT position. The control signal is set by the S1 external control unit.

MAINTENANCE

Clean the product surfaces regularly (once in 6 months) from dust and dirt (Fig. 16-19). Disconnect the fan from
power mains prior to any maintenance operations. To clean the fan, use a soft cloth or a brush wetted in a mild
detergent solution. Avoid water ingress to electrical components.
Wipe the unit surfaces dry after cleaning.

STORAGE AND TRANSPORTATION REGULATIONS

• Store the unit in the manufacturer's original packaging box in a dry closed ventilated premise with
temperature range from +41 ˚F to +104 ˚F and relative humidity up to 70 %.
• Storage environment must not contain aggressive vapors and chemical mixtures provoking corrosion,
insulation, and sealing deformation.
• Use suitable hoist machinery for handling and storage operations to prevent possible damage to the unit.
• Follow the handling requirements applicable for the particular type of cargo.
• The unit can be carried in the original packaging by any mode of transport provided proper protection
against precipitation and mechanical damage. The unit must be transported only in the working position.
• Avoid sharp blows, scratches, or rough handling during loading and unloading.
• Prior to the initial power-up after transportation at low temperatures, allow the unit to warm up at operating
temperature for at least 3-4 hours.
