Filters can be removed from the back or bottom on
horizontal mounted units and from the front on vertically
mounted units. Do not handle unit by coil- or piping
connections as damage may occur. Anchoring the
equipment in place is accomplished by using the mounting
points provided, and positioning the unit on a LEVEL
horizontal plane. The positioning is correct if the drain pan
is pitched horizontally to provide proper drainage when the
unit is installed level.
Units can be installed horizontally and vertically.
Units are designed to be bolted to the wall structure through
the slotted wall mounting holes in the chassis, used for
anchoring to pre-installed studs.
Fixing is provided with the identical mounting slots in the
top panels with hanging rod and field supplied rubber-in-
shear insulators. They can be used for proper suspension and
vibration isolation only in very critical applications.
The type of mounting device is a matter of choice, however
the mounting point should always be at the 4 to 6 points of
the cabinet.
Check that your lifting equipment can safely support the unit
assembly and component weights. See technical data for
unit weights.
All supports must be designed to meet applicable local
codes and ordinances. All fastening devices must be
designed to mechanically lock the assembly in place without
the capability of loosening or breaking away due to system
operation and vibration.
After mounting the unit, it is ready for the connections such
as water, drain and electrical.
3.6 About the Installation Site
When installing the unit, make sure that the
building structure and/or the supporting surface
can withstand the weight of the device. The
weights of the units are detailed in the technical data.
These units have been designed to be installed on the
floor, a wall or a ceiling. Normally rubber vibration damping
supports and internal flexible pipe work are not required.
When the unit is to be installed on the ground, provide for
a concrete supporting plate which shall assure a uniform
distribution of the weights. A special subbase / feet is
generally required.
When selecting the installation site, follow these guidelines:
• The unit must not be installed in the proximity of
open fire or greasy environments: the discharge of
boiler flue gases.
• The unit is installed level on an even surface
• The unit is not allowed to be installed near sources
of contaminated air, like chimneys or exhaust pipes
and the outlets of large-kitchen extractors. Grease might
build up on the fins of air exchangers and filter.
• Although the unit is extremely silent, the valves actuators
and fan(s) may generate a few dB(A) more sound than the
background noise level. In very sensitive situations,
please insulate the unit acoustically in the most
beneficial way.
• Contact an acoustical engineer for obtaining the
most beneficial acoustical results.
• The total experienced sound pressure level in a room is
greatly affected by the room merits.
• Never install in areas exposed to flooding or beneath
drip stones, etc.
• The installation site is suitable for the space required
for air circulation and for the performance of
maintenance operations
