I-TEC and Q-TEC Products – Installing the Product Inside a Room
Indoor products are normally supported by the floor surface and are adjacent to an interior
wall surface, including brick, cement block, metal or wood construction. These products
are normally labeled as “I-TEC” or “Q-TEC” units.
Before installation begins, the floor
surface should be inspected by a construction professional to ensure it will support the
weight of the unit and accessory items.
Approximate weights are available from the product
specification sheet, and a safety factor should be designed into the installation.
A sheet metal sleeve is normally installed in the wall allowing vent and condenser fan air
to enter and exit the unit. Different sleeve depths are available for installation into various
wall depths. Typical fasteners to attach the sleeve to the outside surface of the wall include
tap cons and other fastening devices. The I-TEC or Q-TEC unit is then slid up to the wall
surface and connected to the sleeve using screws. Trim kits are available to enclose gaps
between the wall surface and the unit. A louver grille is used to cover the external wall
opening and fasteners used during sleeve installation.
Wall Sleeve:
Wall sleeves allow for outdoor air
to enter and exit the unit inside
the room.
Air Paths:
Air paths through the unit allow for
cooling operation and fresh air to
enter the structure (I-TEC shown).
Louver Installation:
Outdoor louvers provide an esthetically
pleasing look to the installation and cover
the unit opening (I-TEC shown).
I-TEC and Q-TEC Products – Clearances for Outdoor Condenser Fan Airflow
Solid barriers located too close to the face of the outdoor louver of the I-TEC or Q-TEC can both impede airflow and
force heated air to short circuit (be returned) from the condenser outlet to the condenser inlet. Either condition
will effectively raise the condensing temperature and pressure reducing cooling capacity and efficiency. In extreme
cases, the unit may fail to operate due to high refrigerant pressures inside the unit, and compressor and/or fan motor
failure may occur. It is recommended to allow 15' (457.2 cm) in front of unit louver for proper condenser airflow.
Always use common sense when installing products, follow unit clearances given in the installation instructions
and contact local Bard distributors when additional knowledge is needed regarding unit clearances for proper unit
functionality.
