3) WATER AND ELECTRIC CONNECTIONS
Water inlet
The tap of the water sink (mixer) can supply hot and cold water while the tap of the central basin and the flexible
shower can supply only cold water.
The mixer is connected to N. 2 flexible pipes of  1/2” (one for hot water, the other one for cold water). They must be
connected to the laboratory’s water system using flexible pipes (not provided).
If the laboratory’s water system cannot supply hot water, it is necessary to close the provided hot water pipe using a
 1/2” plug.
The hood is provided with valves of interception hot and cold water. In case of maintenance or failure it is possible to
close the valves in order to interrupt the dispensing of water to all the plumbing of the hood.
Water outlet
Near the water sink there is a  1”1/4 standard siphon. Except changes on request, it is placed on the back side of
the hood at ca. 40 cm from the ground (at ca. 20 cm with garbage disposal unit). Its position depends on the sink
placement.
Important: The outlet system must have a minimum inclination of 1,5°.

4) ASPIRATION SYSTEM
Trimming Tech hoods are provided with:
 Anti-spark three-phase electrofan adjustable through inverter (preinstalled).
 N. 1 synthetic fibres prefilter (preinstalled) to retain possible impurities and improve the filter’s efficiency.
 N. 1 alumina filter for formalin (preinstalled), whose replacement happens from the frontal side simply and
cleanly. Instead of alumina filter, it is possible to ask for activated charcoal filter.
 Arrangement for HEPA filter housing.
 The hood is provided with  250 mm collector on its upper side in order to allow the connection to the hospital’s
centralized canalization system for fumes discharge outside.
 The electrofan allows fumes aspiration from the perforated working surface (over the collecting basin), the
frontal grid (under the shelf) and the grid placed on the upper part (the aspiration from the top is activated
separately, moving the manual lever near the grid). The air is purified passing through prefilter and filter and can
be discharged in this way:
1) FANPREFILTER + FILTERDISCHARGE OUTSIDE THROUGH A NON-ASPIRATED CANALIZATION SYSTEM
(draining pipe not longer than 3 metres, with diameter equal to 250 mm).
2) FANPREFILTER + FILTERDISCHARGE OUTSIDE THROUGH AN ASPIRATED CANALIZATION SYSTEM.
Important:
- In case of non-aspirated canalization, the length of the draining pipe must not be higher than 3 metres, the
diameter must be equal to 250 mm.

5) REPLACEMENT OF FILTER, PREFILTER AND INTERVENTIONS ON
ELECTRIC INSTALLATION
The control system is provided with a digital timer preset at 600 working hours (filter’s middle life).
The control system emits a sound and visual signal (intermittent) to advise when remains ca. 30 hours to reach the
600 expected hours. The warning signal repeats every hour and visualizes the residual hours of use of the hood in
safety.
This alarm can be stopped by pressing the proper key on the touch screen.
When is reached the value of 600 hours, the residual hours of use of machine in safety will be equal to 0 and the
control will show a message of alarm for the replacement of the filters.
