Replacing the safety valve

Replacing the Safety Valve takes approximatly 2 minutes.

Tools and Parts Required

• A replacement safety valve
• A 1/2" spanner/wrench. It's important that a correctly-sized or adjusted spanner is used.

Safety Warnings

• Do not attempt to adjust the Locking Nut on the Safety Valve. The Locking Nut sets the Safety Valve opening pressure and can only be adjusted with special tooling.
  
  
• Do not remove the Safety Valve while hot. Let the machine cool to room temperature first.

• Do not use a Safety Valve which appears damaged or which has been tampered with in any way. It is a safety device which ensures that the machine cannot operate in a dangerous state.

Step 1

While the machine is cold, seperate the Boiler from the machine.

Step 2

Remove the Safety Valve by unscrewing it anti-clockwise from the Boiler by using the ½” spanner/wrench. You should place your spanner around the hexagonal section with flat sides. 

Step 3

Screw the new Safety Valve into the Boiler hand tight, in the clockwise direction, then use the ½” spanner/wrench to tighten so there is metal-on-metal contact between the Boiler and the Safety Valve.

(You won’t need to tighten it very hard, the thing to feel for is a sudden increase in resistance when screwing it in - that’s when you get metal-on-metal contact)
