3.2 Location for Installation
Select an installation site where the following conditions are fulfilled and that meets your
customer's approval.
(1) The EXV box can be installed inside and outside. The control box should be installed
inside.
(2) Do not install the EXV box in or on the outdoor unit.
(3) Do not put the option boxes in direct sunlight. Direct sunlight will increase the temperature
inside the option boxes and may reduce its lifetime and influence its operation.
(4) Choose a flat and strong mounting surface.
(5) Make sure there is enough free space in front and in the side of the AHU-KIT unit for
future maintenance.
(6) The installation site should be far away from heat source, inflammable gas and smoke.
(7) Keep the air handling unit, power supply wiring and transmission wiring at least 1m(39-3/8
inch) away from televisions and radios. This is to prevent image interference and noise in
those electrical appliances (Noise may be generated depending on the conditions under
which the electric wave is generated, even if 1m(39-3/8 inch) is kept.).
(8) Make sure the electronic expansion valve is installed in an upright position.
