SECTION D - ELECTRICAL INSTALLATION

7. INSTALLATION

This section refers to the electric connection required
for the MEC MIX.
7.1 HEATER CONNECTION TO THE POWER
SUPPLY
The electric connection shall be carried out by qualified
operator as per local regulation.
First ensure the power supply is cut-off.
1. Check the proper power supply: 230V/1Ph/50 Hz.
2. Follow the electric diagram delivered togetherwith
the unit; cable H05VVF 3x1,5 mm 2 shall be
used, with max outer diameter equal to 8.4 mm.
3. Leave the ground cable longer than the live and
neutral, to ensure it will ground the unit even in
case of accidentally pulling the power cable.
The efficiency of the grounding cabling is very
important and shall be in compliance with the
local regulation. Any way never use the gas
supply piping for grounding the unit.
4. The unit shall be connected to the power supply
line by means of a 2-poles circuit breaker with
minimum 3mm clearance between contacts.
Both live and neutral lines shall be interrupted
when shutting down the circuit breaker. Cables
used for control panel connection to the unit shall
be protected against electromagnetic interference
by using shielded cables or fixing the control
cables far from power cables.
7.2 INSTALLATION OF THE CRONO
THERMOSTAT
- The electric connection shall be carried out by
qualified operator as per local regulation.
The chrono-thermostat installation shall be
carried out as follows:
1. Find a suitable place to fix the unit, which shall be
at 1.5 m from the floor and not exposed to any
heat source (sun, lamps, etc). Preferably don't fix
the chrono thermostat to an external wall, which
may influence the temperature detecting;
otherwise use an insulation plate placed between
the unit and the wall (polystyrene, cork, etc).
In this way a better comfort can be guaranteed,
by avoiding frequent start and stop of the heater.
2. Use the provided slots on the unit for wall
fixing.
3. Fix the chrono-thermostat by means of two
FISCHER type screws.
4. The chrono-thermostat is delivered already
Connected to the heater by means of a cable
5 m long. The distance can be increased by
using cable extension with 0.75mm2 section
cables. Evaluate the use of shielded cables
if electromagnetic interference may occur.
However the maximum cable length allowed is 30
m.
