Drain Connection And Drain Hose Installation; Outdoor Unit Installation - Hitachi AirCore 700 Installation & Maintenance Manual

4.3 Drain Connection and Drain Hose Installation

Install Drain Connection and Drain Hose
•
The condensate water may drain from the outdoor
unit when the unit operates in heating mode. In
order to avoid disturbing neighbors and protect
the environment, it is necessary to install a drain
connection and a drain hose to drain out the
condensate water. (4~6.5HP: Plugs and drain
connection are optional parts.)
•
Please do the drainage work before the indoor unit
and outdoor unit are connected. Otherwise, it will be
difficult to install drain connection after the machine
becomes immovable.
•
Connect the drain hose (field-supplied) as shown in the
figure for drainage.
NOTE:
•
Do not use the drain connection in a cold region. Drain
may freeze to stop the fan runs.

4.4 Outdoor Unit Installation

•
Use the washer provided in the accessory (except 2.0HP~3.0HP) to fasten the machine at the
foundation bolts.
•
When fastening the outdoor unit with the foundation bolts, the fasten holes position is shown in the Fig. 1.
•
Fasten the outdoor unit as the Fig. 2.
•
Make sure to fasten the outdoor unit tightly and horizontally to prevent noise when the machine is
oblique or inclined by strong breeze or earthquake.
•
Do not drain off water to public places to avoid skidding.
•
A strong base (made of concrete, etc.) should be made. The appliance should be placed not less than
100mm high to avoid being wet or corroded. Otherwise, it may cause damage to the appliance or
reduce its life time. (Fig. 3)
Cut it off, for the long part
of the bolts will make it
difficult to move the unit in
days to come.
