Graco Advanced Glazing Proportioner 24R813

A lithium battery maintains the DM clock when power is not connected.

1. Disconnect power to the DM.

NOTE: This can be done by removing the CAN cable from the bottom of the DM.

3. Remove the old battery and replace with a new CR2032 battery.

4. Properly dispose the old lithium battery according to local codes.

MD2 Only: Install the calibration nozzle onto the dispense applicator

Open the catalyst B ball valve located near the dispense applicator

Calibration Check Assembly Only: Dispense material into a waste container at the calibration check assembly to verify the V/P shown on the DM is at the correct value

NOTE: A restrictor pin for the catalyst B restrictor housing may be required to obtain 5 psi 35 kPa, 0.3 bar or above for the V/P shown on the DM

NOTE: There must be no pressure when adjusting the packing nuts. Air pressure in the feed tanks is too much.

Followed Pressure Relief Procedure, including relieving air pressure in the tanks

• U100: Check iso lube bottle for discoloration.

• Perform Shutdown and install nightcap.

1. Perform Pressure Relief Procedure:

This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing the equipment.

1.1 If electrical power is supplied to the machine, perform Base Purge:

Base purge results in the purging of the base A chemical through the dispense valve. Base purging prevents mixed material within the dispense applicator from curing. The machine will remain pressurized and electrically connected.

1.1.1 Navigate to the Purge/Prime screen.

NOTE: Verify both pumps are activate.

• Check catalyst B filter assembly to prevent crystallization.

Once a week check, clean, and replace (if needed) the following filters.

Catalyst pump outlet filter comes with a 60 mesh filter. Two pack 60 mesh filter replacement kit, 224459, is available.

Catalyst pump outlet filter comes with a 30 mesh filter. Two pack 30 mesh filter replacement kit, 224458, is available.

Once a week, check and tighten throat seals on the pumps and dosing valve.
