•
Avoid exposure to moisture, excessive sunlight and other weather conditions.
•
Make sure the rotary heat exchanger is positioned vertically on the dry and flat ground. Long-term storage on
curved floor may cause tilting of energy recovery wheel and seriously affect the factory pre-calibration. In extreme
cases, warped wheel may scrub the interior of the casing and force the user to perform additional adjustments.
• Support and secure the exchanger against mechanical damages.
•
Keep the storage temperature between 32°F and 89.6°F
• Do not stack exchangers on top of each other. Each product needs to be placed separately.
4. INSTALLATION
The following section contains valuable notes and list of mandatory procedures which are responsibility of the user.
Neglecting advices collected in this chapter may result in product damage, void of warranty or even health loss. Take
time to study carefully whole chapter and make sure everything is understandable. If you have any questions, please
contact support. For more information regarding motors and controllers detailed information please see the Step
Motor Manual.
4.1 Pre-installation assumptions
Do not connect the device to the power supply before getting familiar with this manual
.Installation
procedures should be carried out by qualified personnel.
Swiss Rotors heat wheels are designed to work only and exclusively inside the air handling unit.
Rotary Heat
Exchangers should not be forced to work outside of the AHU or other closed systems. Their desired work
environment is the interior of the ventilation devices. The only justified reason for device extraction could be
completing maintenance tasks such as cleaning, disinfection of wheel or performing annual controls
(only if it is necessary).
Be sure that channels inside the ventilation unit divides rotary heat exchanger at the centre of their energy
recovery wheel matrix. Profile should divide and separate counter flowing air channels.
Make sure that the
air handling unit channels will supply the air to the exchanger evenly. For horizontal installation it is necessary
to apply centre support beneath the wheel. Secure the unit ducts and area below the desired installation
location from falling.
Exchanger need to be installed in a way enabling seamless execution of future maintenance tasks.
AHU
designer needs to anticipate the necessity of easy access for performing basic maintenance procedures.
Rotary heat exchangers require periodic service tasks which should not be limited by lack of access. Each
component of exchanger should be easily reachable.
•
Install the exchanger so that is possible to pull it out of the ventilation unit easily in case of any failure.
• Ensure easy access to the motor.
•
Make sure there is an easy access to both sides of the rotary heat exchanger.
•
If there is a possibility of liquefying condensate occurrence - prepare the floor for such event or place the
dedicated condensation tray underneath energy recovery wheel.
•
Make sure the rotary heat exchanger is firmly attached inside the ventilation system and will not move or oscillate
inside AHU wile fans will start causing the air movement to push against matrix of the energy recovery wheel.
4.2 Motor connection
Depending on the diameter of the wheel inside the rotary heat exchangers, SF and RT series comes with three stepper
motor types matched with the desired parameters. Following notes are quick guidelines concerning motors used in our
products to help with the smooth start-up. For more advanced and detailed instructions, please refer to the separate
motor manual provided with the exchanger.
Motors can be connected, installed, modified and maintained only by professional staff, per local electrical
code. Incorrect installation can cause damage and risk of fatal injuries from electric shock!
For more detailed information please see the Step Motor Manual.
Before connecting the motor, ensure that the supply voltage matches the operating voltage of the device.
