  • Page 2: Compact Design

    The PK series models have been downsized and now require such minimal wall space that they can even be installed above windows. For the PK12FK, 11-13/16in, of wall space between the ceiling and the window allows “above window” installation (13-3/8in for the PK24/30/36FK) 2.
  • Page 3 TEST RUN 3) Convenient 24-Hour ON-OFF Timer The timer allows Mr.SLIM to be switched on or off automatically at the MITSUBISHI ELECTRIC time you set. Once the timer is set, the remaining time is shown on the LCD. 4) Self-Diagnostic Feature Indicates Faults Instantly In the rare case when a problem occurs, the unit stops operating and the set temperature indicator changes to the self-diagnostic indicator, indicating the location of the fault.

  • Page 4: Indoor Unit

    7. HIGH RELIABILITY AND EASY SERVICING In addition to the self-diagnostic function, units are also equipped with a 3-minute time delay mechanism (cooling), an auto restart function, an emergency operation function, a test run switch, etc., to assure high reliability and easy servicing. 8.
