INSTALLATION PROCEDURE
9-1. Installation Diagram of Indoor and Outdoor Uunits
• If the system will be used in cooling mode when the outdoor temperature is below zero, take measures to ensure
that the drain water does not freeze.
• When the outdoor unit is installed in a place that is always exposed to strong winds like on the coast or on a high
story of a building, secure the normal fan operation using a duct or a wind shield.
NOTE
(RAS-***-ND model only)
• Use care to avoid burns. A heater is installed on the base plate of the outdoor unit. When the outside air
temperature is low, the heater runs to warm the base plate even if the unit is not operating so that snow does
not accumulate inside the outdoor unit.
• Do not use the supplied drain nipple for draining water. Drain the water from all the drain holes directly. Provide
a space of at least 50 cm under the outdoor unit so that the draining water does not freeze and block the drain
holes.
Insulate the refrigerant pipes
separately, not together.
