To ensure optimum performance and customer satisfaction, please read these instructions
carefully.
All Defy Console type air-conditioners are tested and rated using the standard Defy wall
sleeve and louvre assembly. Units can safely operate up to 43
°C outdoor temperature. They
have been designed to produce the rated capacity at the lowest power consumption under
International Standard Rating conditions.(ISO5151) at 27°C DB, 19°C WB indoor and 35°
C DB, 24°C WB outdoor, at sea level and with a 230V 50Hz power supply.
To achieve this performance, the following should be noted:
• Smooth curved louvers are used to maximise the condenser airflow requirements.
• Air deflectors which guide the air leaving the unit away from the return air openings are fitted
onto the condenser coil to minimise hot air re-circulation.
• Open cell foam strips are fitted to the condenser end plates and fit tight up against the louvre.
These strips effectively prevent unwanted air from entering or leaving the compartments.
• To prevent rain water from entering via the wall sleeve, the bottom panel of the sleeve slants
outwards . Weep holes at the lower edge allow rainwater to drain away freely.
Architectural and aesthetic requirements often necessitate the use of non standard louver assem-
blies. As these could influence the performance of the units, we undertake to test, free of charge,
any proposed designs in our calorimeter facility
When specifying non standard louvers, please bear the following in mind:
Defy Appliances Limited, manufactures special wall sleeves without louvers. This sleeve is shorter
than standard and thus minimises the gap between the condensing unit and the outside grille
Should the factory fitted foam strips not locate against the louver, insulated divider plates must be
fitted to prevent hot air re-circulation. It is also recommended to remove the side deflectors from
the condenser coil and reposition them directly behind the louvre.
Units installed with flush mounted louvers, need an insulated wall spacer collar to fill the gap be-
tween the indoor unit and the outside wall. In this instance part of the condensing section will pro-
trude into the room. It is important therefore to insulate the condensing section and to ensure that
there are no gaps where heat and noise from the compressor and condenser could enter the room.
