Selecting A Location In Cold Climates; Precautions On Installation; Dimensions And Servicing Space - Rotex RRRQ011AAV1 Installationsanleitung

Selecting a location in cold climates

Refer to "General information" on page 1.
CAUTION
When operating the outdoor unit in a low outdoor ambient
temperature, be sure to follow the instructions described
below.
To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.
Never install the outdoor unit at a site where the suction side
may be exposed directly to wind.
To prevent exposure to wind, install a baffle plate on the air
discharge side of the outdoor unit.
In heavy snowfall areas it is very important to select an
installation site where the snow will 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).

The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.
It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc... (See figure 2)
1 Personal computer or radio
2 Indoor unit
3 Outdoor unit
In extreme circumstances you should keep distances of
3 m or more and use conduit tubes for power and
transmission lines.

4.2. Precautions on installation

Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)
It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.

Install the unit high enough off
the ground to prevent burying in
snow.

4.3. Dimensions and servicing space

The connection piping outlet direction in the installation shown in
figure 4 is frontward or downward. The unit of numeric values
is mm.
When routing the piping backward, secure space of ≥250 mm on
the right side of the unit.
(A) In case of non-stacked installation (See figure 4)
Suction side obstacle
Discharge side obstacle
Left side obstacle
Right side obstacle
Top side obstacle
Obstacle is present
(B) In case of stacked installation
1. In case obstacles exist in front of the outlet side.
2. In case obstacles exist in front of the air inlet.
NOTE Do not stack more than one unit.
About 100 mm 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) In case of multiple-row installation (for roof top use, etc.)
1. In case of installing one unit per row.
≥1000
1 In these cases, close the
bottom of the installation
frame to prevent the
discharged air from
being bypassed
2 In these cases, only 2
units can be installed.
3 In these cases, no
restriction of height L1.
This situation is not
allowed
