PREPARATION

 

Vacuum breaker

 

 

 

1.Power must be secured to the unit at the service breaker. Tag or lock out the service breaker to prevent acci- dental or unauthorized energizing of the machine.

2.Ensure that incoming water to the machine is secured either by use of a shut-off valve or disconnecting the incoming water line.

TOOLS REQUIRED

The following tools will be needed to perform this maintenance evolution:

1.Small flathead screwdriver

2.Needle nose pliers

TIME REQUIRED

It is estimated that it will take (1) person twenty min- utes to perform this task, not including all of the items indicat- ed in the section entitled “PREPARATION”.

IMPORTANT NOTES

1.Read these instructions thoroughly before attempting this maintenance evolution. Become familiar with the parts and what actions need to be taken. This will save time in the long run!

2.Note: Even though the photos in these instructions show a vacuum breaker that has been removed from the plumbing assembly, these maintenance steps could be performed with it installed so long as the requirements in the section entitled “PREPARATION” have been met.

3.Remove the top cap by gripping firmly and turning to the left. The cap should come off after a few turns.

Removing the cap

4.Set the cap to the side.

5.Using the needle nose pliers, gently lift out the plunger and set to the side. Examine the brass seating surface inside the vacuum breaker. The plunger is required to sit flat on this sur- face so it must be free of defects, imperfections and the like. If there is debris, remove it. If it is chipped or cracked then the vacuum breaker must be replaced. Failure to do so may result in the vacuum breaker not working according to its design and could result in damage to the dishmachine.
