Place with at surface where rainwater does not settle or leak.
Place where it is not exposed to strong wind.
Well ventilated place with sufficient service place for repairs and maintenance. (Discharge duct can be purchased

- Consult an installation expert (or company) since you will need to take extra anti-corrosion measures if you need to
install the product in a place where it can be exposed to direct sea breeze. (You have to remove dusts and salinity on
the heat exchanger and apply designated rust inhibitor more than once a year.)
If the outdoor unit is installed in the location where it can be attacked by high wind, please pay attention to these
issues:
- Caution when outdoor unit air outlet side was blow by high wind that speed over 5m/s, Because the outlet air was
suctioned in once again, reduce the airow of machine, and may cause these appearance:
- Lower capacity; -severe frost in heating mode; - machine break down for high pressure .
If the air outlet side of the outdoor unit encountered a large continuous strong wind blowing, the fan will run reversely
with high speed, and may be damaged by it. so please refer to the installation instruction.
