- The noise at the air outlets (at a 45° angle, 1.5 meters in front) is about 5-6 dB (A) higher than the values given in the table.
- The above values apply during Lossnay ventilation when the fan speed is set to high speed.
* Capacity in ( ) is heat recovery capacity by Lossnay core.
Cooling: Indoor: 27°C DB/19
Heating: Indoor: 20°C DB/13.8°C WB
- Noise measurement is carried out in accordance with JIS B8628.
* Mitsubishi Electric measures products according to Japan Industrial Standard (JIS B 8628), therefore Q-H curves are measured by chamber method.
* In the United Kingdam, on-site measurements by pitot tube method could be as much 20% difference from JIS test room conditions. If the meas-
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))

Regarding noise
- In installing work, choose a place that can fully bear the weight of
the Fresh Master and outdoor unit, and where noise and vibration
can be reduced.
- Choose a place where cool or warm air and noise from the out-
door unit's air outlet do not inconvenience the neighbors.
- If any alien object is placed near the outdoor unit's air outlet,
decreased performance and increased noise can result. Avoid
placing any obstacles adjacent to the air outlet.
- If the Fresh Master or outdoor unit produces any abnormal sound,
consult with your dealer.
Maintenance and inspection
- If the Fresh Master and outdoor unit is used throughout several
seasons, the insides can get dirty, reducing the performance.
Depending upon the conditions of usage, foul odours can be
generated and drainage can deteriorate due to dust and dirt, etc.
Time to change the humidifying element (GUF-50, 100RDH4 only)
Because impurities and contamination in tap water accumulate on
the humidifying element, the humidifying power of the humidifying
element decreases gradually.
- If the humidifying power decreases in the course of use, please
consider changing the humidifying element (chargeable to the
customer).
- Although the time to change the humidifying element varies
depending on the conditions such as the operating time and water
