Installation Space; Installation Work - Mitsubishi Electric CITY MULTI PAC-YT52CRA Installation Manual

• To monitor the accurate indoor temperature, install the remote controller away from direct
sunlight, heat sources, and the supply air outlet of the air conditioner.
• Install the remote controller in a location that allows the sensor to measure the representative
room temperature.
• Install the remote controller where no wires are routed around the temperature sensor on the
controller. (If wires are routed, the sensor cannot measure accurate indoor temperature.)
Important
Do not install the controller in a place where
the difference between the remote controller
surface temperature and the actual room
temperature will be great.
If the temperature difference is too high,
room temperature may not be adequately
controlled.
To reduce the risk of malfunctions, do not
install the controller in a place where water
or oil may come into contact with the
controller, or in a condensing or corrosive
environments.

(2) Installation space

Leave a space around the remote controller as shown in the figure shown below, regardless of
whether the controller is installed in the switch box or directly on the wall. Removing the remote
controller will not be easy with insufficient space.
Also, leave an operating space in front of the remote controller.
