Normal Operation:
The Pro3-XP series heat exchangers are tiebolt style frames. This means the press is closed by
using 6 tiebolts to compress the plates. For this type of frame it is important for each tiebolt to take an
equal share of the load. After your heat exchanger is in place you should check the compressed dimension
if the plates were shipped installed. The dimension for your heat exchanger is listed on the first page of
your streaming diagram. Figure 7 shows where the tightening dimension is located on the drawing. If the
plates were shipped in a separate crate refer to the ProFlow manual for instructions on installing them.

Tightening Instructions
Most new plate packs will seal at the start dimension. As the plates and gaskets wear it may be
necessary to compress or close the press further. You should never exceed the minimum dimension shown
on the streaming diagram. If your press is closed to the minimum dimension and leaks are noticed contact
AGC Heat Transfer for technical assistance. Closing the press beyond the minimum dimension could cause
permanent damage to the plates, frame, or both. When measuring the compressed dimension it is a good
practice to take the measurement in several locations on the inside of the fixed end and follower as shown
in figure 8.
