Outdoor Unit Assembly; Execution, Installation And Connection Of The Refrigeration Lines - Olimpia splendid ARYAL S1 E 10 C Instructions For Use And Maintenance Manual

• Another option (figure 16) is to position the gasket (6) on the fitting (5) and then insert the latter into the
hole made on the bottom of the outdoor unit and turn it by 90° to fix it securely.
• Connect a rubber hose (not supplied) to the fitting (6) if water is drained from the outdoor unit in heating
mode.

2.6.2 - Outdoor unit assembly

Proceed as follows (as described in the previous paragraph), once the ideal position for installation of the
outdoor unit has been identified:
a. Position the unit on the support base, respecting the drilling distances indicated in the table in figure X4.
b. Screw any clamping nuts, without tightening completely.
c. Using a spirit level, check the unit is level; if necessary, adjust the support feet.
d. Tighten any clamping nuts correctly.
IN = air inlet - OUT = air outlet
e. If the outdoor unit is higher than the indoor units, to prevent rain entering, a downward bow must be made
along the connection pipe (siphon) before the connection pipe enters the wall. This is to guarantee that
the lowest point of the connection pipe is outdoors.

2.6.3 - Execution, installation and connection of the refrigeration lines

Do not make the connections using normal hydraulic piping, which could contain
scrap residues, dirt or water, and which can damage the unit components and jeop-
ardise correct operation of the appliance.
Only use copper piping, specific for refrigeration, which is supplied clean and sealed
at the ends.
When the cuts have been made, seal the end of the roll and piece cut immediately.
Pre-insulated copper pipes can be used for refrigeration.
Only use pipes with diameters that reflect the dimensions described in the "Technical data" paragraph.
Identify the route of the piping in a way to reduce the length and bends as much as possible in order to obtain
maximum system performance.
Performance is based on standard length and maximum length allowed.
Oil collectors for 5-7 metres must be installed (figure 17).
To establish whether the gas load needs to be topped-up, refer to the table below.
