When the compressor is above the evaporator up to 6 m., An oil trap should always be made at the beginning of the rise
to the condenser.
When the height exceeds 6 m. a trap should be made every 4 m. approx. between each, the total sum should not exceed
9 m. in height.
When you have greater heights than 9 m. an oil separator must be placed between the compressor and the condensing
coil, to avoid the expulsion of the oil to the circuit and that can not return to the compressor, due to the great height
difference.
Important: When get the pipes through the walls, cover the tips to avoid the dirt. The refrigeration pipes must be clean of
dirt and oils and at the moment of welding them it is convenient, to circulate low pressure nitrogen to avoid slag, by the
oxidation of the torch inside the pipe.
Once the welding is finished, from the service valves, circulate high pressure nitrogen through the pipes, to expel any
waste that may have.
Once the interconnection is finished, vacuum the pipes from high and low service valves or on the outdoor unit if it lacks of
service vales and charged with refrigerant gas.
If for any reason it is necessary to vacuum from a single pipe and to the indoor unit, warm the, with the hand so that it
opens and make a vacuum to the whole system.
Once finished and with the unit running for a few hours, check that the oil level (where it has a sight hole) is at normal
levels; otherwise, add oil until you reach the level.
Our units comes fully loaded from factory, and allows up to 5 meters of pipes without adding gas.
