Maintenance (continued)
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.
Vacuum cleaner
(with brush attachment)
CAUTION

* 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 / 50 Hz.
* For the specifications at the other frequency or voltages, contact your dealer.
* The values given in the table for the noise level reflect the levels measured at a position 1.5 meters 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 efficiency (%) are based on winter condition.
* Mitsubishi Electric measures products according to Japan Industrial Standard (JIS B 8628), therefore Q-H 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 difficult 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))

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 filter side downward.
l The filter for LGH-15 and 35RVX-E has front and back side. Set
the "FRONT" (printed) side of the filter on the outer side.
Note
l If
are indicated or the remote controller, turn off the
indication, after maintenance.
