To ensure effective condensate drainage, the drain pipe should be routed on a downward
slope of 2.5 cm/metre.
Adequate heat insulation for the condensate drain pipe should be provided for harsh
climates, or sub-zero temperatures.
Fit the drain pipe and its seal (supplied) if required, BEFORE attaching the unit to the ground.
For Heat pump models, in locations where the outdoors temperature may fall below 1°C, a
condensate anti-freezing protection device must be provided (a heated wrap for example).
When installing the unit in harsh climates, sub-zero temperatures, snow, or humidity it is
recommended that it is raised about 10 cm above ground level.

REFRIGERATION PIPE CONNECTIONS BETWEEN TRIO AND ST
Labels supplied with the TRIO unit enable the valves to be marked as the installation
operations advance.
The indoors units can be installed in 3 different rooms.
Refrigeration pipe lengths are available as an accessory in fixed lengths of 2.5, 5 and 8m.
The pipe lengths are supplied in rolls. They are insulated and fitted with FLARE nuts.
Unroll the pipes carefully, in the opposite direction to the spirals, to avoid bending them.
This operation must only be performed by qualified personnel, in accordance with
refrigeration engineering best practices (brazing, vacuum draining, charge addition, etc...).
The pipe bend radius must be equal to or greater than 3.5 times the outside tube diameter.

REFRIGERATING PIPE CONNECTIONS BETWEEN THE INDOORS UNITS
AND THE OUTDOORS UNIT
Indoors units contain a small amount of neutral GAS.
Do not unscrew the nuts on the indoors and outdoors units before being ready to proceed
with connecting the refrigerating pipes.
The outdoors unit contains sufficient refrigerant fluid for pipes up to a length of 4 metres per
way.
Only use proper pipe bending tools to form the pipe bends in order to avoid any breakages.
To ensure a perfect seal, cover the valve surface with refrigeration oil.

Only use «refrigeration engineering «quality, copper piping and designed for withstanding
pressures at least equal to 30 bars
Use pipe with the appropriate Ø for each model. (Refer to pipe dimensions and tightening
torque values table above).
Insulate each pipe as well as its connectors separately, with insulation material having a
minimum thickness of 6mm.
Attach the refrigerating pipes, the condensate drain pipe and the electrical cable together with
a strap.
Place the FLARE nuts on the pipe ends and prepare them with a pipe end flaring tool.
Use the FLARE nuts fitted to the indoors and outdoors units.
Connect the four ends of the two pipes to the indoors and outdoors units.
Repeat these operations for connecting the 2nd, 3rd and 4th indoors units

VACUUM DRAINING PROCEDURE
The R22 charge is only contained in the outdoors unit.
The indoor unit contains a small quantity of neutral GAS. For this reason, after having
installed the pipe connections, it is imperative to proceed with vacuum draining the
connections and the indoor unit.
The outdoors unit has a valve provided for the installation to be vacuum drained (large
valve).
1. Connect the refrigerating pipes between the indoors and the outdoors units.
2. Connect the vacuum pump to the FLARE connector of the outdoor unit equipped
with the service valve (large connector).
3. Start the vacuum pump and check that the vacuum gauge drops to -0.1Mpa
(-76cm Hg). The pump should be run for at least 15 minutes.
4. Before removing the vacuum pump, you must check that the vacuum gauge
remains stable for 5 minutes.
5. Disconnect the vacuum pump and close the service valve.
6. Remove the cap from the «GAS» and LIQUID» valves and open them with a
hexagonal spanner, in order to release the R22 refrigerant fluid contained in
the outdoor unit.
7. In the case where the refrigerant pipe connection of one way is longer than 4 m.
add an additional charge in accordance with the values stated in Table N° 1.
8. Check the seal on all the connections. Use an electronic leakage detector or a
soapy sponge.
9. Repeat these operations for connecting the 2nd, 3rd indoors units.
