METEO GREEN HE R.S.I.
11 - INSTALLING THE EXTERNAL PROBE
The sensor (Fig. 1.4) must be installed on an external wall of the building
you want to heat, while taking care to comply with the instructions below:
- It must be fitted on the facade most often exposed to wind, on a wall
facing SOUTH or SOUTH-EAST, and taking care to avoid direct sunlight.
- It must be fitted about 2/3 up the height of the façade.
- It must not be near any doors, windows, outlets for air ducts, or near
chimneys or other heat sources.
The electrical connection to the external sensor must be formed using a two-
pole cable (not supplied), with a cross-section of 0,5 to 1 mm² and a maximum
length of 30 metres. It is not necessary to worry about the polarity of the cable
for the connection to the external sensor. Do not form joints in this cable.
If a joint has to be made it must be watertight and adequately protected.
Any conduiting used for the connection cable must be separate from the
conduits used for the power cables (230 Vac).
WALL MOUNTING OF THE EXTERNAL SENSOR
- Install the probe in an area of smooth wall; for brick walls or other irregular
surfaces, prepare a smooth contact area if at all possible.
- Remove the upper plastic cover by turning it anti-clockwise.
- Identify the wall fixing point and drill a hole for the 5x25 expansion grip.
- Insert the expansion grip into the hole.
- Remove the card from its housing.
- Fix the housing to the wall using the supplied screw.
- Attach the bracket and tighten the screw.
- Loosen the cable grommet screw, push in the probe connection cable and
connect it to the electrical terminal.
Remember to firmly secure the cable grommet to prevent humidity from
entering.
- Put the card back into its housing.
- Close the upper plastic cover by turning it clockwise. Firmly secure the
cable grommet.
12 - CONDENSATE COLLECTION
The outlet collector A (Fig. 1.5) collects: the condensate water, any evacua-
tion water from the safety valve and the system outlet water.
The collector must be connected, by means of a rubber pipe (not sup-
plied), to a suitable collection and evacuation system in the storm water
outlet and in compliance with current regulations.
The external diameter of the collector is 20 mm: we therefore suggest
using an Ø 18-19 mm pipe, to be closed with a suitable clamp (not
supplied).
The manufacturer is not responsible for any damage caused by the lack
of a collection system.
The outlet connection line must have a guaranteed seal.
The manufacturer of the boiler is not responsible for any flooding caused
by interventions of the safety valve.
13 - GAS CONNECTION
Before connecting appliance to gas pipe network, check the following:
- regulations in force are met
- gas type used is the same as set for appliance operation
- pipes are clean.
Gas must be piped externally. If the pipe goes through a wall it must go
through the central opening in the lower part of the template. It is recom-
mended to install an appropriately sized filter on the gas line in case gas
from the mains contains some small solid particles. After installation make
sure that all the joints have been made airtight conforming to standard
installation practices
14 - ELECTRIC CONNECTION
To access the electrical connections, proceed as follows:
- unscrew the lower cover fixing screw B, (Fig. 1.6)
- loosen the fixing screws (A - B) (Fig. 1.3) and remove the shell
- open the terminal board (Fig. 1.7 : high voltage connections 230 V, low
voltage connections.
Connect the appliance to the mains power supply with a switch featuring a
distance of at least 3,5 mm (EN 60335-1, category III) between each wire.
The appliance uses alternating current at 230 Volt/50 Hz, has a power input
of 88 W (25kW R.S.I.) and 116 W (35kW R.S.I.) and complies with EN 60335-
1 standard. Connect the boiler to a safe earth circuit according to current
legislation. Live and neutral (L-N) connections should also be respected.
12
The boiler can operate with phase-neutral or phase-phase power supply. For
floating power supply, without an earth-bonded conductor, it is necessary to
use an insulation transformer with secondary anchored to ground.
The earth conductor must be a couple of cm longer than the others.
Gas and/or water pipes may not be used to earth electrical equipment.
The installer is responsible for making sure that the appliance has an
adequate earthing system; the manufacturer shall not be held liable
for eventual damages caused by incorrect usage or failing to earth the
boiler.
Use the supplied power cable to connect the boiler to the mains power
supply. Connect the ambient thermostat and/or time clock as shown in the
electrical diagrams.
When replacing the power cable, use a HAR H05V2V2-F cable, 3 x 0,75
mm², Ø max. external 7 mm.
