10. Remove the Follower Bracket and Screw (Fig. 4-2) and set aside for reassembly.
11. Pull the Follower frame plate back far enough to expose the internal Plate Assembly (Fig.
4-2).
12. Remove the Splash Guard (Fig. 4-2), and set aside for reassembly.
NOTE:
The plates must be reassembled in the exact order and configuration, so the order
should be recorded or plates marked to ensure proper configuration during reassembly.
It is suggested to mark the plates with a diagonal line, as shown in Figure 4-3b in order
to easily record proper order and orientation of the plates.
Cleaning the Plates
4.3.2.1
CAUTION!
Always wear gloves and eye goggles when using cleaning detergents.
 Consult a cleaning specialist for a suitable choice of detergent. Ensure that all detergents
used are compatible with the plate and gasket material before use.
 If plates are removed for manual cleaning, make sure they are re-fitted in the exact same
order and orientation when refitted.
 Use ONLY nylon or other types of “soft” scrubbing brushes when cleaning the plates.
 The plates use gaskets to prevent contamination of the water being heated, and these must
be removed in order to clean the plate properly. Use acetone or other types of solvents
which do not contain chlorine to remove old gasket glue. Alternatively use an BLP gas flame
heating the reverse side of the plate. Do not use any other type of gas, which may produce
a “harder” flame. Boiling water can be used with some success.
 For thick scaling or organic material, the plates may be submerged in a tank of appropriate
cleaning agent in order to dissolve deposits and/or soften organic contamination.
CAUTION!
Never use a metal brush, steel wool, or sand/glass paper. This will damage the passivation
film of the plates.
 A high pressure cleaner may be used, but care should be exercised and abrasives never
used.
 Clean thoroughly. Insufficient cleaning may result in reduced water flow, lower thermal
output, and shortened heat exchanger life expectancy.
