Installation guidelines / precautions Daikin Altherma
Installation location (General)
n The equipment is not intended for use in a potentially explosive atmosphere.
n The equipment is not intended for use in a potentially explosive atmosphere.
n Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.
n Choose a location where the hot/cold air discharger from the unit or the operation noise will not cause a nuisance to the neighbours of the user.
n Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
n There must be sufficient space for carrying the unit into and out of the site.
n There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
n The site must be free from the possibility of flammable gas leakage in a nearby place.
n Locate the unit so that the noise and the discharged hot/cold air will not annoy the neighbours.
n Install units, power cords and inter-unit cables at least 3 m away from television and radio sets. This is to prevent interference to images and sounds.
n Depending on radio wave conditions, electromagnetic interference may still occur even if installed more than 3 m away.
n In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the outdoor unit.
n Since drain flows out of the outdoor unit, do not place anything under the unit wicht must be kept away from moisture.
Installation location (in cold climates)
n To precent exposure to wind, install the outdoor unit with its suction side facing the wall.
n Never install the outdoor unit at a site where the suction side may be exposed directly to wind.
n To prevent exposure to wind, install a baffle plate on the air discharge side of the outdoor unit.
n Unit shoud be installed in a way that a minimum of 10 cm free space is assured below the unit’s bottom plate at all conditions, e.g.: heavy snowfall (if necessary construct a
pedestal).
n In heavy snowfall areas it is very important to select an installation site where the snow ill not affect the unit. If lateral snowfall is possible, make sure that the heat exchanger coil
is not affected by the snow (if necessary construct a lateral canopy). (See figure)

This situation is not allowed.
1 In these cases, close the bottom of
the installation frame to prevent
discharged air from being
bypassed.
2 In these cases, only 2 units can be
installed.
B. Stacked installation
1. Obstacles exist in front of the outlet side
2. Obstacles exist in front of the air inlet
C. Multiple-row installation
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.
1. Installation of one unit per row
2. Installing multiple units (2 units or more) in lateral connection per row

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