2.5 General Installation Requirements
The Viega ProPress Stainless 󶈵tting system must be installed while
considering the following general industry requirements.
2.5.1 Required Tools
The following tools are required for making a press connection:
■ Pipe cutter or a 󶈵ne-toothed hacksaw
■ Deburring tool
■ Marker for marking insertion depth on the tube
■ Press machine with constant pressing force
■ Press jaw or press ring with corresponding actuator suitable for the
tube diameter and with the proper pro󶈵le
2.5.2 Expansion
Thermal expansion in installed systems generates stress on the tubing
and appliance connectors. Compensation must be allowed for expansion
and contraction that may occur within the system. Expansion joints or
mechanical expansion compensators may be used to alleviate these
stresses. ProPress Stainless systems do not require any additional
protection when compared to traditional joining methods.
The following methods are e󶈴ective:
■ Fixed and sliding hangers
■ Expansion equalization joints (expansion bends)
■ Expansion compensators
Improper Tool/Material Damage
Only use press jaws and rings that are designed for use
with ProPress 󶈵ttings.
