3 Selection of Installation Location
CAUTION
Device Overview
Install the outdoor unit in a location where there are no areas under or near the
outdoor unit in which noise and vibration could pose a serious problem.
(Special care must be given when operating in residential areas.)
(1) For vibration isolation materials, be sure to use a vibration isolator designated by
Daikin.
(2) Inspection and certification are performed only for optional items designed specifically
for the Daikin GHP.
Using items not specifically designed for use by the Daikin GHP may cause problems like
abnormal vibration, etc.
Install the outdoor unit in a location where there are no walls near the outdoor unit
that could reflect or resonate with the operating sound.
There must be enough space to construct a soundproofing wall for operational
noise.
Install the outdoor unit in a location where sufficient space can be retained for the
safe performance of maintenance services when constructing a signboard tower or
soundproofing wall around the outdoor unit.
Install the outdoor unit in a location where piping work can be performed using a
refrigerant piping length and height difference that conform to the relevant
regulations.
Install the outdoor unit in a well-drained, flat location where rainwater will not form
puddles or high water.
Take care not to let fan-driven exhaust blow against or operating sound transmit to
neighboring buildings. (Special care must be given to installation areas where
building are located close together.)
To perform the cooling operation at the outdoor air temperature of 0 °C or lower,
setting the memory switch for the outdoor unit with the use of AirGuard (option) is
required. Refer to Test Run Manual for the setting method.
Select a location where draining is possible.
Install the unit on a level surface that can support the weight of the unit and
maintain stability.
Install the unit in a location where blow-out air from the air-to-heat exchanger and
exhaust gas from the engine does not directly affect the others.
Do not install a BS unit to the ceiling of a room under a bedroom or similar noise-
sensitive rooms because the sound of flowing refrigerant can be perceived as an
abnormal noise.
