CAUTION
Ensure that the handling of residuals after using chlorines follow local
envionmental regulations.
6.2 Opening
During manual cleaning, it is necessary to open the heat exchanger to clean
the plates.
NOTE
Before opening the heat exchanger, check the warranty conditions. If in
any doubt, contact the Alfa Laval sales representative. Refer to Warranty
conditions on page 7.
WARNING
If the heat exchanger is hot, wait until it has cooled down to about 40°C
(104°F).
WARNING
If necessary, use proper protective equipment, such as safety boots,
safety gloves and eye protection, depending on the type of media in the
heat exchanger.
6.2.1 Bolt configuration
The bolt configuration of the heat exchanger varies between different models.
The major force of the plate pack is held by the tightening bolts (TB). To
distribute the force evenly over the frame plate and pressure plate, locking
bolts (LB) are used as well. The locking bolts can be shorter and can have
smaller dimensions. In the opening and closing procedure, it is important to
identify the tightening bolts (TB) and the locking bolts (LB). Refer to the picture
below.
