3.
Fan maintenance (once per year).
Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the unit performance and
decrease supply air flow.
Clean the fans with a soft brush or cloth. No water and abrasive detergent, sharp objects or solvents are allowed for cleaning to prevent
the impeller damage.
4.
Condensate drainage maintenance (once per year).
The drain pipes may get clogged with the extracted particles.
Pour some water inside the drain pan to check the pipe for clogging. Clean the U-trap and the drain pipe if required.
5.
Ductwork system maintenance (once in 5 years).
Regular maintenance operations listed above may not completely prevent dust accumulation in the unit, which results in reducing
performance of the unit. Duct maintenance means regular cleaning or replacement.
6.
Control unit maintenance (if necessary).
The control unit maintenance must be performed by an expert qualified for unassisted operations with electrical installations with the
voltage up to 1000 V after careful reading of the user's manual.
TROUBLESHOOTING
Trouble Possible
reasons Troubleshooting
The fan does not get started.
No connection to power supply.
Make sure the power supply line is connected
correctly, otherwise troubleshoot a connection error.
Low air flow.
Filters, fans or the heat exchanger
are soiled.
Clean or replace the filters. Clean the fan(s) and
the heat exchanger.
The ventilation system is
contaminated or damaged.
Clean the ventilation system components. Replace
the damaged components.
Noise, vibration.
The impeller is soiled.
Clean the impellers.
The screw connection of the fan or
the casing is loose.
Tighten the mounting screws of the fans or
the casing against stop.
Water leakage.
The drainage system is clogged
or damaged. Wrong installation of
the drain system.
Clean the drainage system. Check the drain line
slope angle. Make sure that the U-trap is filled with
water and the drain pipes are frost protected.
Displayed alarm indicator
on
the control panel.
Communication loss (cable or wire
breakdown) between the control
panel and the ventilation unit.
Check the power and connection cables and wires
between the control panel and the air handling
unit for integrity using a multimeter. If unassisted
troubleshooting fails, please contact the product Seller.
Wrong cable installation.
Make sure the cable installation is completed
according to the requirements. Otherwise install
the cable as required.
Displayed DI1 and DI3 errors on
the control panel. The error coding is
the same for both heaters.
Activated heating mode in
the control panel whereas
the heater is missing.
For error troubleshooting deactivate the heating
mode. If the errors are displayed after that please
contact the product Seller.
STORAGE AND TRANSPORTATION REGULATIONS
Store the unit in the manufacturer's original packing box in a dry ventilated premise at ambient temperatures from +5
°
C up to + 40
°
C.
Storage environment must not contain aggressive vapours 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 packing by any mode of transport provided proper protection against precipitation and
mechanical damage.
Avoid sharp blows, scratches or rough handling during loading and unloading.
Do not expose the unit to sudden changes in temperature. Such changes can lead to condensation of moisture inside the unit and
performance disturbance during the unit activation.
Prior to the initial power-up after transportation at sub-zero temperatures allow the unit to warm up at room temperature for at
least 2 hours.
