Condensate drains
The condensate drains are not assembled when delivered and are stored in the electrical panel with their clamping
collars. To assemble them, insert them on the condensate tray outlets and use a screwdriver to tighten the collars.
DELIVERY CHECKS
Preliminary checks
Before installing the equipment, the following points MUST be checked:
• Have the forklift protections been removed?
• Is there suf
fi cient space for the equipment?
• Is the surface on which the equipment is to be installed suf fi ciently 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 speci
fi cations?
• Is drainage provided for the condensate?
• Is there suf
fi cient 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 fl ow 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 air
fl ow 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
fl ows.
• 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
fl uids and type of rooms.
NOTE: The packaging protection fi tted on the fi nned surfaces must be removed prior to start up.
