* The above values apply during Lossnay ventilation when the fan speed is set to Fan speed 4 at the rating pressure loss and 230 V / 60 Hz.
* For the specications at the other frequency or voltages, contact your dealer.
* The values given in the table for the noise level reect the levels measured at a position 4.9 feet(1.5 m) immediately below the unit in an
anechoic chamber.
* Noise change or increase may occur because of the Bypass-Automatic function or Automatic fan speed change by timer setting and/or other
functions.
* Temperature Exchange efciency (%) are average of summer and winter condition.
* Mitsubishi Electric measures products according to ISO 16494:2014, therefore P-Q curves are measured by chamber method.
* On-site commissioning measurements by pitot tube method could be as much 20% difference from JIS test room conditions. If the measuring
point is close to sources of turbulence like bends, contractions and dampers etc, it is difcult to measure air volume correctly. A straight duct
length more than 10D (D=duct diameter) from the source of turbulence is recommended for correct measurement. On-site measurement
should therefore be measured in accordance with BSRIA guideline (Commissioning Air System. Application procedures for buildings
AG3/89.3(2001))
Maintenance (continued)
Vacuum cleaner
(with brush attachment)
Lossnay core
CAUTION
lDo not use the hard nozzle of the vacuum cleaner. It may
damage the exposed surfaces of the Lossnay cores.
lUnder no circumstances should the Lossnay cores be washed
in water.
2) Lossnay cores
Use a vacuum cleaner to suck up the dust and dirt on the exposed
surfaces of the Lossnay cores.
Use a soft brush only to clean exposed surface areas.
Do NOT wash in water.
Assembly after maintenance
Bearing in mind the following points, assemble the parts following
the sequence for their removal in reverse.
lArrange the Lossnay core with the air lter side downward.
lThe lter has front and back side. Set the “FRONT” (printed)
side of the lter on the outer side.
Note
lIf are indicated on the remote controller, turn off the
indication, after maintenance.
If you hear strange sounds, if no air is blown out or if some other
trouble occurs, switch off the power and contact your dealer. Consult
with your dealer concerning the cost of inspection or repair work.
Consult with your dealer about the after-sales services provided for
this Lossnay product.
After-sales servicing
■ Recommended inspection and maintenance
After several years of use, the following might occur. We recommend inspection and maintenance by a professional.
- Entry of dust due to deterioration of lters
- Abnormal noise or vibration due to the motor reaching the end of its service life
- Air leakage due to the Lossnay core reaching the end of its service life
The following are consumables: Motor / Supply air lter / Exhaust air lter / Lossnay core / Circuit board / Thermistor
■ Repair costs include technical fee, cost of parts, (and business trip charges), etc.
Attentive inspection
Inspect your unit of good service!
Have you
noticed?
● Fan do not run when the unit is turned on.
● Abnormal noises or vibrations while the unit is running.
● Retarded or irregular rotations.
(Motors are component which requires maintenance.)
● Burnt odor.
● Corroded or damaged installation section.
Stop
running.
Turn off the unit. Then,
contact your dealer for
prevention of failure or
hazard. The dealer should
appraise the possible cost.
