Before performing the installation, read these instructions
carefully to make sure you are familiar with the unit details.
The unit dimensions (item 4.3) and weights (table 2) are found
in this manual and also in the technical catalogue.
The following rules apply to all installations.
a) First refer to the applicable Codes and/or Rules for the
installation of the unit on-site, power supply, etc. to ensure
that it conforms with the standards and requirements
specifi ed (Local Standards).
b) Carefully plan the location of the units to avoid possible
interference with any type of existing (or designed)
installations such as: electrical installations, water piping
and sewers, etc.
c) Install the unit where it is free from any obstruction in air
circulation, both in the air outlet (discharge) and in the
return (See item 4.4) air.
d) Choose a location with enough space for general repairs
or maintenance.
e) The site should allow the passage of pipes.
f) The unit must be properly leveled after installation.
g) For normal and safe operation, when unit is installed in
places with high wind exposure such as the coast, or tall
buildings, use a duct or wind shield.
Avoid installation in the following locations:
•
Saline sites such as the coast or places with large
amounts of sulfur gas. In these places, special protection
should be used.
•
Locations with exposure to oil, vapor or corrosive gases.
•
Locations near organic solvents.
•
Locations where drainage water may cause some type of
problem, such as contamination, etc.
4.1. General recommendations
4. Instalation
Check if the unit is installed in a place without
risk of fl ammable gas leak. If infl ammable gases leak
around the equipment, combustion may occur.
CAUTION
• The units should be positioned in a location that will
provide enough support for them and also protect
against severe weather.
• Make sure the Units are attached to a base to prevent
movement.
IMPORTANT
Each unit should have independent power.
IMPORTANT
4.2. Installation on Site
Before placing the equipment on site, check the following
aspects (all models).
a) The fl oor should support the unit weight while in
operation.
(See 2 - General Technical Features).
Check the structural design of the building or applicable
standards to see the loads allowed. Install reinforcements
when required.
b) Provide enough space for maintenance services
according to the fi gures in sub-item 4.4 - Minimum
Recommended Clearance for installation. The front of
the equipment must remain unobstructed to allow free
fl ow of air and access to the interior of the unit.
The electrical connections can be made on both sides
of the units. The unit also has a lower connection at the
base of the equipment.
NOTE
Settling the unit
Always refer to the “Dimensions & Clearances” chapter to
confirm that there is enough space for all connections
and service operations. Regarding the center of gravity
coordinates, the position of the unit mounting holes, and the
weight distribution points, refer to the certified dimensional
drawings provided with the unit.
Before positioning the unit, make sure:
• The allowable load on the spot is appropriate, and
reinforcement precautions are taken.
• The surface is horizontal and flat.
• There is enough space above the unit for air flow.
• There are appropriate support points and they are in the
correct location.
• The location is not subject to flooding.
• In locations where there is heavy snow and long periods
with temperatures below zero, the unit should be
lifted above the height of the normal course of wind or
snow. Shields may be required to deflect intense winds
or prevent snow falling directly on the unit. It is not
necessary to restrict the flow of air into the unit.
•
Locations near machines that generate high frequencies.
•
Locations where the discharge of air from external
units directly interferes with the well-being of the
neighborhood.
•
Locations that are exposed to strong and constant wind.
•
Locations that are blocked for passage.
