INSTALLING THE OUTDOOR UNIT
• Install the outdoor unit 200mm(8˝) higher than the base surface and install the drain hole to connect the
pipe to the drainage.
• The concrete foundation should be 1.5 times larger than bottom of the outdoor unit.
• Condensed water may be generated in heating operation. Pay attention to waterproof and drainage of
the concrete foundation where the outdoor unit is installed.
(An ice may form on the base surface in winter.)
• It is necessary to install wire mesh or steel bar when outdoor units are installed at soft foundation.
• When installing multiple outdoor units at the same place, install the H beam on the concrete foundation.
(When installing a number of outdoor unit, you can install it on the concrete foundation.)
• Install the H beam[150mm(6˝) x 150mm(6˝) x t10(3/8˝) : basic specification] or vibration absorption frame
to jut out from the concrete foundation.
• After installing the H beam or vibration absorption frame, apply corrosion protection.
• Install a square pad[t=20mm(3/4˝) or more] or vibration absorption frame to prevent vibration of the
outdoor unit delivering to the base surface when installing the concrete for the outdoor unit.
• Place the outdoor unit on the H beam or vibration absorption frame and fix it with the bolt, nut and
washer. (The bearing force is more than 3.5kN)
• Do not install the outdoor unit on a wood palette.
• Fix the outdoor unit securely to the base surface with anchor bolts.
• The manufacturer is not responsible for the damage occurred by not keeping standard of the
installation.
