• In certain functional environments, such as kitchens, server rooms, etc., the use of specially

designed air-conditioning units is highly recommended.

• Only trained and certied technicians should install, repair, and service this air

conditioning unit.

• Attempts to self-install can lead to inecient performance, and risk of equipment damage over

time.

• Strictly follow the installation instructions set forth in this manual.

• Improper installation may result in electrical shock, short circuit, leaks, ﬁre or other damage to

the equipment.

• Before you install the unit, consider strong winds, typhoons, and earthquakes that might aect

your unit, and locate it accordingly. Failure to do so could cause the equipment to fail.

• After installation, ensure there are no refrigerant leaks and that the unit is operating properly.

Refrigerant is both toxic and ﬂammable, and poses a serious health and safety risk.

technician.

Product uninstallation and recycling must be performed by a certiﬁed technician.

If the system has a leak-detection system installed, it must be checked for leaks at least every 12

months.

When the unit is checked for leaks, proper record-keeping of all checks is strongly recommended.

Failure to observe a warning may result in death. The product must be installed by

installers or contractors who are licensed HVAC professionals and in compliance with

all local, state, and provincial laws.

Failure to observe a caution may result in injury or equipment damage.
