10 Installation in Areas of High Salinity
10.1 Caution
Do not install outdoor units where they could be directly exposed to sea air. Corrosion, particularly on the condenser and
evaporator fins, could cause product malfunction or inefficient performance.
Outdoor units installed in seaside locations should be placed such as to avoid direct exposure to the sea air and additional
anticorrosion treatment options should be selected, otherwise the service life of the outdoor units will be seriously
affected.
Air conditioning installed in seaside locations should be run regularly as the running of the outdoor unit fans helps prevent
build-up of salt on the outdoor unit heat exchangers.
10.2 Placement and Installation
Outdoor u
nits should be installed 300m or more from the sea. If possible, well-ventilated indoor locations should be
chosen. (When installing outdoor units indoors, outdoor unit discharge ducts should be added. See Part 3, 3 “Outdoor Unit
Ducting and Shielding”.) Refer to Figure 3-10.1. If it is necessary to install outdoor units outside, direct exposure to the sea
air should be avoided. A canopy should be added to shield the units from sea air and rain, as shown in Figure 3-10.2.
Ensure that base structures drain well so that outdoor unit footings do not become waterlogged. Check that outdoor unit
casing drainage holes are not blocked.

10.3 Inspection and maintenance
In addition to standard outdoor unit servicing and maintenance, the following additional inspections and maintenance
should be undertaken for outdoor units installed in seaside locations:
A comprehensive post-installation inspection should check for any scratches or other damage to painted surfaces and
any damaged areas should be repainted/repaired immediately.
The units should be regularly cleaned using (non-salty) water to remove any salt that has accumulated. Areas cleaned
should include the condenser, the refrigerant piping system, the outside surface of the unit casing and the outside
surface of the electric control box.
Regular inspections should check for corrosion and if necessary corroded components should be replaced and/or
anti-corrosion treatments should be added.
