3. INSTALLATION
3.1 Assembly and installation
Following illustrations and instructions presents the correct assembling of the motors and controller with the casing
of the rotary heat exchanger. Motors are designated to be firmly attached to casing of the exchanger. Pulleys are
selected to match the expected speed, efficiencies and performance of the motors. Please refer to the Chapter 2 -
Product Description and Technical Specification to determine the correct set of components for the product. Pulley
wheels must be firmly attached to the shaft of the motor.
Do not change the motor configurations. Follow the correctly selected setup given in the first chapter
of this manual (see Table 2). Changing the settings is associated with poor performance of the rotary
wheel and risk of incorrect attachment to the housing of the exchanger, and most importantly, the risk
of motor damage, as well as electric shock due to incorrect connection.
Warning: Incorrect mechanical installation of the motor can be a cause of error alerts.
Following illustrations represents stepper motor assembly and installation methods. Each of the stepper motor model
has its own way of assembly and may differ in according to Table 2 Available motor configurations.
Important notes:
Stepper motor must be fixed firmly to a casing via dedicated motor holder.
Stepper motor must be grounded.
Do not use cables or connectors other than that included in the set with motor and controller.
Do not change the size of the pulley wheel. Optimal pulley sizes were calculated and chosen to match the
desired performance of the Rotary Heat Exchanger.
Position the controller correctly to avoid overheating. Avoid exposure to direct sunlight.
Check the specification plate on the motor and controller to confirm electrical configuration.
