Choosing The Position Of The Unit; Unit Assembly; Drilling The Wall - Olimpia splendid MAESTR SMART Instructions For Installation, Use And Maintenance Manual

2.3 - CHOOSING THE POSITION OF THE UNIT (fig.2-3)
the unit must be installed on a wall that directly communicates with the outside. the position for installing
the unit must have the following prerequisites:
• The height of the unit's lower edge from the floor should be at least 100 mm/4" if fixed to the wall in the
lowest position.
• If fixed to the wall in the highest position, it should be at least 90 mm/3.5" from the ceiling.
• The wall on which the inside unit is installed must be of sufficient strength to withstand its weight.
• There must be adequate space around the unit for any maintenance or service that may be necessary.
• There should be nothing in the way of the air that needs to circulate both on the top air-intake (curtains,
plants, furniture) or at the front where the air exits. this could cause air swirls that cause the performance
and efficiency of the unit to suffer.
• It must be possible to leave room around the unit for any maintenance operations that may be necessary.
• Nothing can be in the way of the air that needs to circulate both on the top air-intake (curtains, plants,
furniture) and at the front where the air exits. this could cause air swirls that would inhibit the working
efficiency of the unit.
When selecting the unit's location as described above the installer must insure there are no
structures or systems (beams, piers, pipes, wires, etc.) at the points where the holes are to be
drilled. Interference from any item would prevent drilling the holes required to install the unit.
• The unit should not be placed under curtains that may block free movement of the air.
• Do not spray water or other liquids of any kind directly on the unit.
• The unit should not be installed in a position where the airflow can directly strike occupants in the con-
ditioned space.
• Never force open the airflow fap.
• Do not place any other object on the air grill that may even partially obstruct the grill itself.
• The unit should not be installed directly over another appliance, such as a television set, radio, refriger-
ator, etc., or over any other source of heat.
• Do not store anything on the unit as it will limit airflow, reduce capacity and increase energy costs.
• Do not attempt to manually open or close the modulating damper or spray corrosive cleaning agents
into the unit.
• Do not allow curtains or other hanging materials to block the flow of air entering or exiting the unit.
• Do not allow airflow to directly strike occupants as their comfort will be negatively impacted. Also, do not
install the unit in close proximity to heat producing appliances or devices.

2.4 - UNIT ASSEMBLY

the maximum length allowed for pipes is 990 mm/39". the pipes must be smooth on the inside with a diam-
eter of 200 mm/8". Pipes cannot be curved or bent. it is strongly recommended to use the grilles provided,
or grilles which provide the same features.
2.4.1 - DRILLING THE WALL (fig.4-5-6)
install the unit by drilling two holes (diameter of both pipes must be either 160 mm/6.4" or 200 mm/8" through
the wall as indicated on the drilling template. the 200 mm/8" holes will ensure best performance and lowest
air noise. Drill the wall using the proper tools, taking care to prevent excess damage to the wall or surround-
ing areas.
to drill the holes, proceed as follows:
• Fasten the drilling template to the wall with adhesive tape that will not damage the surface, leaving the
necessary space from the ceiling, floor and side walls as shown on the template. Use a small drill or
punch to mark the exact center of each of the holes to be drilled.
