time the refrigerant filters are replaced.

The oil must also be replaced whenever it changes color due to absorption of humidity. Before
beginning the oil change procedure, procure a container of at least 500 cc capacity in which to
collect the used oil. The pump contains about 250 cc of oil. Use only the oils recommended by
the manufacturer (consult your retailer); the use of a non-recommended oil may impair the
proper functioning of the pump and void the warranty.
