2.3.- SERVICE SPACE
Free space should be left to enable access for servicing, in order to check the installation of
the cables, drainage connections, electrical installation and cleaning fi lters, as well as to give
easy access to the unit.
2.4.- DRAINAGE
All units have a 3/4” steel threaded drainage pipe welded to the condensation tray.
Drainage pipes will be fi tted for each tray through a siphon with a height difference of 80
mm. to avoid drainage problems from the depression formed by the fans. The pipes should
have a 2% slope to enable condensation to be drained easily.
Also tip the unit slightly (2%) toward the drainage side. Check that the condensation trays are clean
and free of dirt and other debris from the installation work and that water drains correctly.

Min. 80 mm
Inspection and cleaning cap.
2.5.- REFRIGERANT CONNECTIONS
The unit is supplied with gas and liquid lines, sealed with copper caps.
THE UNITS ARE SUPPLIED WITH NITROGEN GAS. THIS MUST BE REMOVED BEFORE PROCEEDING AS FOLLOWS:
1 Remove the nitrogen gas through the top and bottom 5/16” service ports, leaving a vacuum as a safety measure.
2 Remove the caps from the connecting pipes.
3 Braze the connecting pipes.
(When brazing refrigerant pipes, nitrogen gas must be supplied through the service ports into the pipes to remove
any air).
DURING INSTALLATION OPERATIONS, KEEP GAS AND LIQUID PIPES COVERED, IN ORDER TO PREVENT HUMIDITY AND
DIRT FROM GETTING INTO THEM.
TAKE SPECIAL CARE TO ENSURE THAT REFRIGERANT PIPES ARE INSULATED.
AVOID COLLAPSE ON PIPE LINES INSTALLATION.
- 100D and 120D units model use different sizes of pipe connections: big size
for circuit 1 and small size for circuit 2.
Please be sure to connect indoor unit circuits C1 and C2 to the corresponding C1 and C2 circuits of the outdoor unit.
2. INSTALLATION
Legislation does not allow refrigerant gas emissions to the atmosphere, so the refrigerants have to be recycled to avoid being
released to the atmosphere. Those recycled refrigerants shall be processed afterwards by an authorized waste manager.
Those components derived from the recycling of the unit have to be managed by authorized waste manager or be left in local
waste facilities according the local normative in each country.
