Installation, Transferring Works, And Checking; Specifications - Mitsubishi Electric City Multi PEFY-WP.VMS1-E serie Bedienungshandbuch

If malfunctions persist after you have checked the above, turn the power supply OFF and contact your dealer with information about the product name, the nature of the
malfunction, etc. If the display of "[CHECK]" and (4 digit) check code flashes, tell the dealer contents of the display (check code). Never attempt to repair by yourself.
The following symptoms are not air conditioner failures:
• The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of cosmetics, the walls, fur-
niture, etc., absorbed in the air conditioner.
• The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and other sections due to
expansion and contraction caused by temperature change. This is normal.
• The fan speed changes in spite of not changing the setting. Not to blow out cold air at the beginning of heating operation, the air conditioner automatically adjusts the fan
speed gradually from lower to the set speed. It also adjust its fan speed to protect the fan motor when return air temperature or fan speed excessively rises.

7. Installation, transferring works, and checking

Regarding place for installation
Consult with your dealer for details on installation and transferring the installation.
Caution:
Never install the air conditioner where there is a risk of leakage of flammable
gas.
If gas leaks and accumulates around the unit, fire can result.
Never install the air conditioner at the following place:
• where there is a lot of machine oil
• near the ocean and beach areas where there is salt air.
• where humidity is high
• where there are hot springs nearby
• where there is sulphurous gas
• where there is a high-frequency processing machinery (a high-frequency welder,
etc.)
• where acid solution is frequently used
• where special sprays are frequently used
• Install the indoor unit horizontally. Otherwise, water leakage can result.
• Take sufficient measures against noise when installing the air conditioners at hos-
pitals or communication-related businesses.
If the air conditioner is used in any of the above-mentioned environments, frequent
operational failure can be expected. It is advisable to avoid these types of installation
sites.
For further details, consult with your dealer.
Regarding electrical work
Caution:
• The electrical work must be undertaken by a person who is qualified as an
electrical engineer according to the [technical standard respecting electri-
cal installation], [internal wiring rules], and the installation instruction man-
ual with the absolute use of exclusive circuits. The use of other products
with the power source can result in burnt-out beakers and fuses.
