PRELIMINARY CHECKS
Before installing the equipment, the following points MUST
be checked :
-Have the forklift protections been removed ?
-Is there sufficient space for the equipment?
-Is the surface on which the equipment is to be installed
sufficiently solid to withstand its weight? A detailed study of
the frame must be made beforehand.
-Do the supply and return ductwork openings excessively
weaken the structure?
-Are there any obstructing items which could hinder the
operation of the equipment?
-Does the electrical power available correspond to the
equipment's electrical specifications?
-Is drainage provided for the condensate?
-Is there sufficient access for maintenance?
-Installation of the equipment could require different lifting
methods which may vary with each installation (helicopter or
crane). Have these been evaluated ?
-Ensure that the unit is installed in accordance with the
installation instructions and local applicable codes.
-Check to ensure that the refrigerant lines do not rub against
the cabinet or against other refrigerant lines.
In general, make sure no obstacles (walls, trees or roof ledges)
are obstructing the duct connections or hindering assembly
and maintenance access.

INSTALLATION REQUIREMENTS
The surface on which the equipment is to be installed must
be clean and free of any obstacles which could hinder the
flow of air to the condensers:
-Avoid uneven surfaces
-Avoid installing two units side by side or close to each other
as this may restrict the airflow to the condensers.
Before installing a packaged Rooftop unit it is important to
understand :
-The direction of prevailing winds.
-The direction and position of air flows.
-The external dimensions of the unit and the dimensions
of the supply and return air connections.
-The arrangement of the doors and the space required to
open them to access the various components.
CONNECTIONS
-Ensure that all the pipe-work crossing walls or roofs are
secured, sealed and insulated.
-To avoid condensation problems, make sure that all pipes
are insulated according to the temperatures of fluids and
type of rooms.
NOTE: The AQUILUX protection sheets fitted to the finned
surfaces must be removed prior to start up.
