PRELIMINARY CHECK ITEMS
Before installing the equipment, the following items MUST
be checked :
- Is there sufficient space for the equipment?
- Is the surface on which the equipment will be placed
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?
- Does the noise level of the equipment meet the
specification ?
- Is drainage provided for the condensate?
- Is there sufficient access for maintenance?
- Installation of the equipment could require different lif-
ting 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 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

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 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.
Figures 12 & 13 show the required clearances for both Smart
& Linea units
CONNECTIONS
- Ensure that all the pipework crossing walls or roofs are
secured and insulated to avoid condensation problems.
NOTE : The AQUILUX covers which protect the finned
surfaces must be removed prior to unit commissioning.
