MAINTENANCE
Cleaning
The chassis, manifold, and valves and
fittings may be cleaned with a damp
cloth. The top and front of the 4871 and
MRS may be cleaned with a lightly
dampened cloth containing mild soap
solution. The heater, the back of the
4871, and the back of the MRS should
not be directly exposed to any liquid
cleaning agent.
Note: Disconnect from power source
before cleaning.
Fuses
The replacement of protective fuses and
backup AA size, 3.6 V battery for the
4871 Controller are the only internal
maintenance procedures that should be
performed by qualified personnel.
Proper fuse rating should be discussed
with Parr Instrument Company
Technical Support. Advanced
troubleshooting instructions can be
obtained by calling Parr Instrument
Company to determine which parts may
need to be replaced or serviced.
Head gaskets
Some extrusion of the PTFE gasket will
occur if the vessels are operated in 200
- 300 °C range. Normally this extrusion
doesn’t preclude reuse of the gasket;
the extruded portion should be removed
with a sharp knife. However, when the
gasket thickness is reduced to half of its
original thickness, it should be replaced.
If an FKM O-ring head gasket is used,
the life of the gasket will be shortened if
the operating temperature is above
200 °C. FFKM O-ring seals may be
used up to 275 °C. Unfortunately they
are very expensive and will generally be
reserved for unique applications. EP O-
rings may be used up to 150 °C.
Rupture discs
With normal use, rupture discs should
be replaced annually. More frequent
replacement may be necessary
depending on the operating conditions.
