Machine positioning

In case of ceiling installation, each unit is provided with anti-vibrating support plates.
With reference to figure 6 the following are instructions to fix the unit to its supports :
1. Carry out the drilling of the ceiling, and fit the four M8 threaded bolts (1).
2. Position the unit on the four bolts using the supplied fixing plates (6).
3. Insert antivibrator (2), washer (3) and screw nut (4) and lock nut (5) without blocking.
4. Install the unit with 3 mm inclination towards the condensate outlet to aid the condensation going out.
5. Block the unit tightening the fixing bolts.
In case of floor (or roof) installation, interpose a support frame (or leg) H 150 mm min between unit and floor (or roof), so that drain
traps can be installed.

Air duct connections

IMPORTANT: IT IS IMPORTANT NOT TO PLACE IN OPERATION THE UNIT IF THE FAN OUTLETS ARE
NOT DUCTED OR NOT PROTECTED BY A SAFETY NET ACCORDING TO THE ACTUAL RULE.
•
The ducts must be as rightly sized as unit air performance can meet air plant resistance.
•
In order to prevent the formation of condensation and cut down the sound level it is advised to use internally lined ducts.
•
In order to avoid the transmission of unit vibrations into the environment, it is advised to fit an antivibrating joint between
the fans and ducts. The electrical continuity must be guaranteed between the ducts and the apparatus via an earth cable.

Water connections

The installation and connecting of the piping is an operation that must be done correctly, otherwise it may compromise the
performance of the system. At worst it may cause irreversible damage to the machine. These operations are to be effectuated by
qualified personnel.
Water drainage connection
•
The drainage system must be provided with an adequate trap (on each drainage point), able to allow the condensation run
off on under pressure conditions.
•
The trap must be designed as shown on figure 7
•
The trap must have a tap for correct cleaning of the lower part, and must allow an easy disassembly.
•
The path of the condensation drainage tube must always have a gradient toward external.
•
Insure that the condensation run-off tube does not interfere with discharge of the unit.

Electrical connections

Before starting any operation, make sure that the general power supply has been
isolated. All the electrical connections must be protected at the source by the installer.
•
Electrical connections to unit electrical board must be carried out by qualified personnel according to the supplied
diagrams; all the external electrical connections to unit or its options (later fitted) must be carried out by installer or
qualified personnel
•
Insure that the voltage and the frequency shown on the technical plate correspond to the connecting power supply.
Follow the connection of the unit and its accessories using adequate cabling for the power used, and respecting the
country regulations. The dimensions of the cabling must be sufficient to support a voltage drop in start up phase
inferior to 3% of the nominal.
•
For the general power supply of the unit and its accessories, the use of adapters, multiple plugs and extension leads is to be
avoided.
