8. Fresh air intake (Design guide)
1-way (2 series) Air Discharge Cassette Type
Caution
The fresh air shall be treated by heat reclaim ventilator or the like.
Be sure to decide the fresh air volume so that mixed suction air with fresh air keep operating
temperature.
*1.Recommended treated air temperature is 12 °C to 30 °C.
However, please make a fresh air volume within 20% of standard.
Model name MMU- AP0152SH AP0182SH AP0242SH
Standard air flow (m3/h) 750 780 1140
Provide an air filter in fresh air duct.
(Fresh air doesn't pass through the filter of Indoor unit.)
Be sure to insulate the fresh air duct.
Please wire for inter - lock with fan of Heat exchanger unit and Indoor unit.

Connect the driving relay of the duct fan(DC 12V) between 1 and 6 on the indoor P.C. board.
(Rated current of the relay for duct fan shall be up to 75mA.)
After installation, implement a trial operation to check that the duct fan of the indoor unit start/stop
simultaneously.
(Implement the trial operation following to the installation manual of the indoor unit.)
