• After the filling process close the black valve (11) immediately
• Close the valve of refrigerant cylinder or can too
• Open red valve (10) and check the pressure and temperature of the system
• If the pressure is ok, close all valves
• Remove all hoses and open all valves
Service of manifold:
• The charging hoses must be checked and clean of oil residue before each use. A visible
control is also necessary to ensure that the hoses and the connection are undamaged
and tight.
• The seals and gaskets of the manifold are parts of use and must therefore be replaced
from time to time. The manifold must be tested regularly to ensure the valves are tight.
• If a manifold shows to be leaking, the pistons of the valves can easily be changed and
are available as a spare part. Please refer to the manifold accessory section of the
REFCO catalogue.
• If the sight glass is leaking a replacement kit is available. To change the sight glass a
special tool is necessary (M4-6-11-T, Part No. 4493169) which is also available from
REFCO. Replace and tighten the new sight glass carefully in order to prevent damaging
the glass.
• To change the valve core on models with t-style or vacuum gauge connection, use a
valve core screw driver A-32000 from REFCO.
• After changing spare parts on the manifold it is absolutely necessary to test
the manifold for tightness before the next use.
Further accessories and charging hoses for REFCO manifolds can be found in the REFCO
catalogue or on the web www.refco.ch.
Disposal of manifold:
• Dispose of the manifold according to the rules and regulations of the country of use.
