INSTALLATION

Foundation Bolts

The customer is to furnish all foundation bolts and piping etc. Refer to specification and certified drawings for listing of parts being supplied by H.T.Engineering Works.

The certified drawing shows the foundation bolt size and pitches. It is recommended that foundation bolts be set in suitable sized pockets.

Install the PurgePac 1000 by lowering it with the foundation bolts attached to the base such that the bolts enter the prepared pockets.

Leveling blocks should be placed in position and the machine approximately leveled before the foundation bolts are finally grouted.

DO NOT complete the grouting of the machine at this stage until the machine has been finally leveled. Allow sufficient time for the grout around the foundation bolts to set before accurately aligning and leveling the machine. Check that all foundation bolts are correctly tightened, machine align and leveled. If these are satisfactory, proceed with grouting the machine.

Connect the inlet, reject, discharge and dilution pipework. It is essential that all piping be well supported so that no strain is placed on the PurgePac. Consideration should be given to providing loose flanges on pipes that bolt onto the PurgePac. These loose flanges may be welded to the pipe after the holes are seen to match. Use ¼" (6 mm) rubber jointing.

Mount the motor on the motor support (if motor was not supplied with the unit). Install the pulley on the motor shaft and align it with the pulley on the PurgePac® 1000 drive shaft. Assemble the v-belts and adjust for proper tension

CAUTION: DO NOT OVERTIGHTEN BELTS AS THIS MAY REDUCE
BELT LIFE AND CAUSE PREMATURE BEARING FAILURE

Lubrication

The housing has been filled with grease at the factory. However, this may have settled prior to installation, therefore it is recommended that 15-20 strokes be pumped into each bearing after cleansing the greasing points.

See the lubrication section of this manual for grease recommendations.

ESID® Rotor Clearance

Make sure that the bolt, which holds the rotor cover to the drive shaft, is tight.

Check the clearance between the rotor and the perforated plate; this would be 1.0 to 1.5mm.

While the top cover is off the DetrashPac, jog the motor to check the rotation. The ESID® rotor should turn counter-clockwise when viewed from the top.

Bottom Accept Valve

The handwheel-operated slide valve should be always opened. Opening rate of valve is according to reject flow

OPERATION

Before Start-up

Check the PurgePac® 1000 body for absence of foreign material like rags, tools, etc.

Flush out the pipework and the machine using clean water.

Check for correct operation of valves and water feeds.

Check for correct motor rotation.

a.) Open the accepts valve and the reject valve by 50%.

b.) Open sealing water line and regulate flow.

c.) Start the PurgePac® I drive motor.

d.) Set the detrashing control panel.

e.) Adjust the accepts valve to give the required flow.

f.) Make sure the rejects are flowing. The inlet pressure should be 1.5 to 2 bars.

g.) The flow resulting from the accepts valve should maintain the pressure within the detrasher and ensure it is completely filled with stock.

Normal Start-up Sequence

a.) Open the sealing water line.

b.) Start the detrasher motor.

c.) Set the detrashing control panel to Auto.
