Please refer to the following table containing most important things user should check before performing first start-
-up:
Inspect tasks
Check
Exchangers was delivered in a perfect condition, without missing parts and with sealed screw con-
nections.
Exchanger outer dimensions fit the place intended for installations inside the AHU.
AHU is ready and tailored for the installation of rotary heat exchanger.
There are no unwanted objects or obstacles inside the casing of the exchanger.
Wheel spins freely inside the casing and is not scratched or damaged at any place.
Drive belt is placed and tightened properly on the pulley and wheel.
Current with the appropriate parameters specified in the motor manual is provided on site.
Motor is connected accordingly to its manual schematics.
Purge sector was installed properly and rigidly.
If all the requirements listed above are met, you can start the first run. For the first 15 minutes of operation, you should
carefully observe the components and make sure that the installation has been carried out successfully. Pay attention
to all moving components. The motor should run evenly without rotation fluctuations and without excessive heat rele-
ase. Make sure the purge sector is installed in the right position, depending on airflow.
Check the wheel as often as possible for the first 12 hours. Standard inspection intervals are described in the follo
-
wing Maintenance chapter.
6. MAINTENANCE
6.1 Safety
Fully disconnect the device from the power supply before carrying out any service operations. All electrical
work should be carried out by qualified staff only. Incorrect electrical connection can result in fatal injuries
or product damage.
Do not touch any moving parts inside the rotary heat exchanger. While performing any service tasks remem-
ber to use protective gloves. Turn of the whole HVAC system before performing any servicing operations.
6.2 Energy Recovery Wheel
Swiss Rotors strongly recommend checking the condition of individual components according to the time table provided
in this chapter. Technical control is obliged to the user. Properly frequent checks allow early detection of irregularities in
the system and may help avoiding serious damages resulting from various random factors. Please refer to our general
proposed inspection checklist and timetable presented below. Some inspection operations cannot be carried out
when the exchanger is disconnected and does not work. Therefore, if possible, check the components during normal
exchanger operation and again after disconnecting from the power supply.
Remember to keep precautions while performing checks on working exchanger - do not touch moving parts under
any circumstances.
