Instructions for installation and connection of the unit
Hatches should be installed on each discharge duct bypass and where access is planned for cleaning
and replacement of filters.
1.5.3 Specifications for the foundation or anchoring of the unit
Where the unit is to be installed at ground level, the characteristics of the ground it will sit on must be
taken into account.
Characteristics, such as acceptable surface firmness, must be suitable for the foundation the unit
requires.
1.5.4 Unit refrigerant connection
The indoor and outdoor units are connected by coolant pipes that form a sealed coolant circuit.
Pipes to be used
C A U T I O N
Do not leave compressors or dehydrator filters exposed.
Use K or L-type cooling quality copper pipes, S/ASTMB88.
The pipes must be sealed and insulated until they are connected to the units.
The pipe insulation must be made of a suitable material with a minimum thickness of 8 mm to avoid
condensation and minimum temperature loss due to radiation.
Connection pipe installation
D A N G E R
Do not carry out work outdoors in the event of adverse weather conditions
C A U T I O N
Do not use stripping products on Cu ‑ Cu joints.
Use rods with a low melting point and a minimum silver content of 5% when welding the pipes. During
this process, there must be a current of dry nitrogen inside the pipe to prevent rust and scale from forming
that would damage the welding and, therefore, affect the watertightness of the circuit.
N O T E
•
The connection pipes between units must be as short as possible.
•
No drain traps are necessary where connecting piping specifications are met.
