In these cases, close the bottom of
the installation frame to prevent
discharged air from being
bypassed.
In these cases, only 2 units can be
installed.
This situation is not allowed.
Figures between ( ) indicate the dimensions
only for the 100-125-140 class models.
B. Stacked installation
1. Obstacles exist in front of the outlet side
2. Obstacles exist in front of the air inlet
Do not stack more than one unit.
About 100mm is required as the dimension for laying the upper outdoor unit’s drain pipe.
Get the portion A sealed so that air from the outlet does not bypass.
C. Multiple-row installation
1. Installation of one unit per row
2. Installing multiple units (2 units or more) in lateral
connection per row

ERHQ_W18 units include special equipment (insulation heater sheet, à) to
ensure good operation in areas where low ambient temperature can
occur together with high humidity conditions. In such conditions the
ERHQ_W1 models may experience problems with severe ice build up on
the aircooled coil. In case such conditions are expected, the ERHQ-W18
must be installed instead. These models contain countermeasures
(insulation, heater sheet, à) to prevent freeze up.
