Base; Vibration Damping - TCF ZAE Series Installation, Operation And Maintenance Manual

- heat exchanger extraction side
Minimum distance Lb = (B+O.2) m
where B = machine width (m)
- inspection side e Minimum distance Li = 1.2 m
lf you do not have the minimum space requirements as
specified above, the Unit doors can, on request, be
fitted using PVC clamps instead of hinges. In this case
the minimum distance will be Li = 0.7 m

Base

The permanent installation of the Air Treatment Unit
may be made:
- directly on the floor (Hg. 4a)
- on a concrete bed (fig. 4b)
- on a steel section bed (fig. 4c)
- on a suspended base (fig. 4d)
Both the floor and the beds must be capable of
withstanding the machine weight to within the
required safety margins.
The Air Treatment Unit must be positioned on a
horizontal surface so as to prevent:
- damage to the fan motor units caused by uneven
weights on the vibration dampers
- malfunctioning of the condensate drains
- difficulty in opening and closing the inspection doors.
The horizontal alignment of the support surface must
be checked with a SPIRIT LEVEL; adjustments may be
made using STEEL SHIMS.

Vibration damping

In order to ensure effective protection against
vibrations, the Air Treatment Unit must be installed as
follows:
- suitable DAMPERS in material designed to withstand
the weight involved must be placed between the
machine and the support surface
- the Unit must not be fastened directly with screws but
by means of brackets (fig. 5).
Even in the case of suspended installation of the Unit, the
supports must not be screwed directly into the ceiling;
vibration damping material must always be placed
between the supports and the ceiling (fig. 6).
It, for reasons connected with increased protection,
spring-operated or rigid rubber vibration dampers are
required between the machine base and the support
surface, the hydraulic connections must be fitted with
appropriate JOINTS.
