7 Installation details
7.1 Installation instructions
The air conditioner should be placed on a firm foundation to minimize noise and vibration. For safe and
secure positioning, place the unit on a smooth, level floor strong enough to support the unit. The unit
has casters to aid placement, but it should only be rolled on smooth, flat surfaces. Use caution when
rolling on carpet surfaces. Do not attempt to roll the unit over objects. The unit must be placed within
reach of a properly rated grounded socket. Never place any obstacles around the air inlet or outlet of
the unit. Allow 30cm to 100cm of space from the wall for efficient air-conditioning.
Your window slider kit has been designed to fit most standard "Vertical" and "horizontal" window
applications. However, it may be necessary for you to improvise/modify some aspects of the installation
procedures for certain types of window. Please refer to Fig. 2 & Fig.3 for minimum and maximum
window openings. Window slider kit can be fixed with a bolt (see Fig.3a).

Note: If the window opening is less than the mentioned minimum length of the window slider kit, cut that one
with a hole in it short to fit for the window opening. Do never cut out the hole in window slider kit.
