2.7.2 -
Connections
The choice and sizing of the hydraulic lines must be made by an expert who must operate according to
the rules of good technique and the laws in force.
To make the connections:
- position the hydraulic lines
- tighten the connections using the "spanner and counter spanner" method (fig. 12 ref. B)
- check for any leaks of liquid
- coat the connections with insulating material (fig. 12 ref. C).
The hydraulic lines and joints must be thermally insulated.
Avoid partially insulating the pipes.
Do not over-tighten to avoid damaging the insulation.
Use hemp and green paste to seal the threaded connections; the use of Teflon is advised when there is
anti-freeze in the hydraulic circuit.
2.8 - CONDENSATION DISCHARGE
The condensation discharge network must be suitably sized (minimum inside pipe diameter 16 mm) and
the pipeline positioned so that it keeps a constant inclination, never less than 1%. In the vertical instal-
lation, the discharge pipe is connected directly to the discharge tray, positioned at the bottom of the side
shoulder underneath the hydraulic fixtures. In a horizontal installation the discharge tube is connected to
the one already present on the machine.
For installation of the SL versions in a horizontal position, horizontal condensation collection basin
accessory kits are available SL.
- If possible, make the condensation liquid flow directly in a gutter or a "rainwater" discharge.
- When discharging directly into the main drains, it is advisable to make a siphon to prevent bad smells
returning up the pipe towards the room. The curve of the siphon must be lower than the condensation
collection bowl.
- If the condensation needs to be discharged into a container, it must be open to the atmosphere and the
tube must not be immerged in water to avoid problems of adhesiveness and counter-pressure that would
interfere with the normal outflow.
- If there is a height difference that could interfere with the outflow of the condensation, a pump must be
mounted (accessory kit):
- in a vertical installation mount the pump under the lateral drainage tray;
- in a horizontal installation the pump position must be decided according to the specific requirements.
In any case, consult the specific instructions in the condensation discharge pump kit.
However, on completion of the installation it is advisable to check the correct outflow of the
condensation liquid by slowly pouring about ½ l of water into the collection tray in about 5-10
minutes.
2.8.1 - Mounting the condensation discharge device in the vertical version
Connect to the condensation collection tray discharge union (fig. 13 ref. A) a pipe for the outflow of the
liquid (fig. 13 ref. B) blocking it adequately. Check that the drip-collector extension (fig. 13 ref. C) is present
and correctly installed.
2.8.2 - Mounting the condensation discharge device in the horizontal version
To mount the horizontal bowl on the SL versions refer to the instructions in the relative optional kit.
- Below the side corresponding to the condensate drain tube outlet, cut the pre-cut area (fig. 14 ref. A).
- Refit the side panel.
