15.3 Handling Screens

MONGOOSE PRO units have four pretensioned screens and ten wedges per shaker basket (two are spares on the
cable tower). Once screens are placed on the screen bed, wedges are driven between each screen edge and support
bars on shaker sidewalls. The screen bed is slightly crowned at the center causing screen frames to bow when
wedges are forced in place. This prevents screens from "whipping" up and down during shaker operation.

15.3.1 Removing Screens

1. Initiate a controlled shutdown of the equipment.
PERFORM LOCKOUT / TAG OUT PROCEDURES TO ISOLATE THE UNIT FROM RIG
POWER SUPPLY.
WARNING
WASH DOWN THE SCREEN AREA PRIOR TO INSTALLING NEW SHAKER SCREENS.
TIP
USE A RUBBER MALLET TO AVOID DAMAGING THE SCREEN WEDGES.
