When the length of the main suction pipe （ single course and including the pipe length in vertical position ） exceeds 10
meters, charge the refrigerant oil according to the following rules:

Refrigerant Oil
The piping of the refrigeration system should be connected by welding as much as possible. In the welding, the method of
charging the pipe with nitrogen should be adopted to prevent the occurrence of scale, and also to protect the valve gasket and
packing from heat damage.
The refrigerant used in the condensing unit should be of the type indicated on the compressor's nameplate, and other refrigerants
should not be misused. The compressor of the R404A refrigerant condensing unit is charged with special synthetic refrigerating
oil. This special refrigerating oil is not allowed to be mixed with other mineral oils or synthetic oils, and this special synthetic
refrigerating oil is highly susceptible to moisture, so it should be connected to the system after the refrigeration system is fully
dry. The compressor of the condensing unit using R22 refrigerant is charged with (our company coded) mineral oil.
For scroll unit, it is possible to directly add refrigerant oil more than 35% of the original amount (see the catalogue), and for the
rotor unit, it is recommended to charge the refrigerant more than 25% of the original amout. Before connecting refrigeration
system, ensure all components clean and dry. Pipes connected to unit should be flexibly structured. The horizontal section of
suction pipe should be inclined to the direction of compressor. The flow rate of the gas to ensure oil return should be not less than
4 m/s. The flow rate of the refrigerant vapor in the vertical ascent section of the suction pipe should be not less than 8 m/s , but
the flow rate of refrigerant in air tube shouldn't exceed 15 m/s. When the evaporation temperature is below 10 °C, the suction
For the R404A refrigerant system, pay special attention to the leakage check of the welded joint. For systems using R404A
refrigerant, speacial dry filter, expansion valve, pressure switch and sight glass and other accessories should be used. Dry filter
can not adopt silica gel. Refrigerant charging equipment and vacuuming equipment should be used exclusively and should not be
mixed with R22's.
