7.3.4 To perform a leak test
The leak test must satisfy the specifications of EN378‑2.
Pressure leak test
NOTICE
Do NOT exceed the unit's maximum working pressure (see "PS High" on the unit
name plate).
1 Charge the system with nitrogen gas up to a gauge pressure of at least
0.2MPa (2bar). It is recommended to pressurize to 3.0MPa (30bar) in order
to detect small leaks.
2 Check for leaks by applying the bubble test solution to all connections.
NOTICE
ALWAYS use a recommended bubble test solution from your wholesaler.
NEVER use soap water:
▪ Soap water may cause cracking of components, such as flare nuts or stop valve
caps.
▪ Soap water may contain salt, which absorbs moisture that will freeze when the
piping gets cold.
▪ Soap water contains ammonia which may lead to corrosion of flared joints
(between the brass flare nut and the copper flare).
3 Discharge all nitrogen gas.
