CHAPTER 3
EQUIPMENT OPERATION
3.1 SAFETY INSTRUCTIONS FOR EQUIPMENT OPERATION
Caution should be exercised in all aspects of system operation. Safeguards against potentially
hazardous situations have been provided by ANDRITZ, but common sense is the operator's best
protection.
These are the most important safety instructions for operating the Aqua-Screen
®
:
1. Confirm that guards, access doors, and covers are securely fastened before operating the
equipment.
2. During equipment operation, manual intervention in the machine is strictly prohibited. Such
interventions, such as lifting and adjusting the machine, or cleaning the shower nozzles, can be
performed only by approved operating personnel at the appropriate servicing points, with the
power locked out.
3. If it is necessary to clean the equipment during operation or no-load operation, use only a hose
and water pressure at a safe distance from rotating and pull-in areas of the equipment.
4. Power must be disconnected before touching any internal panel or drive part. High voltage may
be present even when the machine is not running. If used with rectifier power supply, all AC
line connections to power supply must be disconnected. With other power supplies, all DC lines
and field connections must be disconnected, as well as power from auxiliary devices such as
pumps, conveyors, fans, and the like.
The screen must be grounded properly to avoid serious injury to personnel. Grounding must be in
accordance with the National Electrical Code and consistent with standard local practices.
3.2 STARTUP AND OPERATION OF THE AQUA-SCREEN
®
Before starting the Aqua-Screen
®
for the first time, check the following items:
1. The channel is clear of debris.
2. All bearings have been greased.
3. All protection devices — such as emergency stop push buttons — are operational.
4. Operate the filter screen and look at the direction of rotation, the state of the perforated plates,
and lateral side sealing plates and polyurethane seals.
5. Abnormal noises or knocking during operation; if any abnormal noises are detected, stop the
Aqua-Screen® immediately and contact ANDRITZ.
