Mount the indoor unit at the proper position for even distribution of indoor air temperature.
•
Ensure that there are no obstructions near the air vent of the indoor unit to stop air flow.
•
Ensure that the indoor unit is not installed in the equipment room or kitchen as the oil, gas or mist
•
may enter into the indoor unit. If oil is attached to the heat exchanger, it may degrade the indoor
unit's performance and even damage the unit's plastic parts.
When the indoor unit is installed in a hospital or near other medical facilities with electromagnetic
•
waves, the following precautions must be highlighted:
(a) Ensure that the indoor unit is not mounted at a position where the electromagnetic waves can be
directly irradiated on the electric cabinet, wired remote controller, wireless controller, wireless
infrared receiver and transmission wire.
(b) The indoor unit must be installed far away (with at least 9.8ft[3m] distance in-between) from the
sources of electromagnetic source.
(c) The wired remote controller must be installed inside iron box, and the transmission wire is routed
in an iron pipe with both the box and pipe reliably grounded.
(d) In case of any clutter wave in the power supply, a filter must be installed to eliminate the same.
Ensure that the indoor unit is not installed under an environment with acid or alkali as both are
•
corrosion to the heat exchanger.
