3 B- ection B WARNING: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation.. Introduction This section describes how to replace the tank and manifold. It includes an overview of the tank assembly procedures for replacing the tank and manifold parts lists for the tank assembly and unit frame Refer to the following sections for additional information on the tank and manifold: Description gives tank specifications, including the tank capacity, the tank volume, and the dimensions of the tank lid opening. Operation gives the procedure for filling the tank with adhesive. Maintenance gives procedures for flushing the tank and manifold and for draining adhesive from the tank. Hydraulics includes the manifold assembly parts list. Control includes procedures for replacing the tank resistance temperature detector (RTD) or thermostat. 2. Overview of the The tank holds a supply of adhesive and melts it before it is pumped to the hoses and guns. An RTD and overtemperature thermostat sense the tank temperature and provide input to the control system. The tank is heated by cast-in heating elements V

4 B-2 3. and Manifold Replacement Because the tank and manifold have no moving parts, you should not need to replace them. However, if you need to remove them from the unit for any reason, follow these procedures. Refer to the parts lists at the end of this section for the part numbers of any components that need to be replaced. You can use the parts list illustrations as a guide as you perform the following disassembly and reassembly procedures. To replace both the tank and the manifold, you must complete all of the following procedures: Preparing to Replace the or Manifold Disassembling the and Manifold Reassembling the and Manifold Restoring the Unit to Normal Operation These instructions can also be used to replace just one part of the tank assembly. Preparing to Replace the or Manifold Complete this procedure before you perform any tank repairs.. Heat the unit to operating temperature to aid disassembly and to prepare for draining as much adhesive as possible from the tank. 2. Drain the tank. For information about different ways to drain the tank, refer to Flushing the ystem in the Maintenance section. 3. Turn the pump air pressure regulator to 0; then disconnect the air regulator from the unit. 4. Remove the pump from the unit. Refer to Pump Removal in the Hydraulics section. NOTE: The procedure for removing the pump includes steps for relieving system pressure and locking out electrical power to the unit V

5 B-3 Disassembling the and Manifold Follow this procedure to remove the tank and manifold and to disassemble them.. If you have not already done so, complete Preparing to Replace the or Manifold. 2. Remove the unit s front and back panels. To do so, you will need to remove the electrical enclosure lid loosen some of the tank lid screws disconnect any ground wires 3. ee Figure B -. Remove the tank lid assembly Fig. B - Removing the Lid Assembly 4. ee Figure B -2. Remove the screws (2) that hold the air line adapter (3) to the hose-end panel () Fig. B -2 Removing the Air Line Adapter crews. Hose-end panel 3. Air line adapter 2. Air line adapter screws V

6 B-4 Disassembling the and Manifold (contd.) 5. Remove the screws on the bottom of the hose-end panel. wing the panel and wire harness away from the unit. 6. If the unit is attached to a support platform, remove any anchoring bolts. 7. ee Figure B -3. Remove the RTD, thermostat, and ground wire (if present) from the tank A Fig. B -3 Removing an RTD and Thermostat (typical) 8. Tilt the unit back at an angle to gain access to the base and remove the screws and washers that attach the manifold to the base. Return the unit to the level position. NOTE: Ask an assistant to help you tilt the unit and support it while you remove the screws and washers. 9. Pull the tank and manifold away from the unit. The spacers between the manifold and the base may come loose at this time. If they do not, remove them by hand. 0. Disconnect the tank heater wires.. Carefully remove all insulation. 2. eparate the tank cover and gasket from the tank. 3. Remove the tank strainer from inside the tank V

7 B-5 4. Remove the screws and washers that secure the manifold to the tank; then separate the manifold from the tank. 5. Remove the two O-rings from the grooves in the manifold and discard them. You should replace the O-rings any time the manifold is separated from the tank. Refer to Manifold Assembly Parts List in the Hydraulics section for the O-ring part number. Reassembling the and Manifold Follow this procedure to reassemble the tank and manifold and to reinstall them on the unit.. Turn the tank upside down and place it on a flat surface. 2. ee Figure B -4. Lubricate two new O-rings with O-ring lubricant and place the O-rings in their grooves on the manifold A Fig. B -4 Installing New O-rings 3. Turn the manifold upside down and align it correctly on the tank. NOTE: If the O-rings are lubricated, they will stay in the grooves when you turn the manifold upside down V

8 B-6 Reassembling the and Manifold (contd.) 4. Insert the manifold washers and screws in the bottom of the manifold and tighten them finger tight only. Then tighten the screws in the sequence shown in Figure B -5. Tighten the screws to Nm (4--5 ft-lb) A Fig. B -5 Correct equence for Tightening Manifold crews 5. Turn the tank and manifold over so that the tank s open side is up and wrap the insulation around the tank and manifold. Use high-temperature duct tape to secure the insulation. 6. Reconnect the heater wires to the tank heater connections. 7. Hold the spacers in place and attach the tank and manifold to the base of the unit with the screws and washers removed earlier. It may be necessary to tilt the unit to gain access to the bottom of the base. Tighten the screws to Nm (8--0 ft-lb). NOTE: Be sure you do not pinch the heater wires when you are securing the tank and manifold to the base. NOTE: To ease assembly, you can cut the heads off of four M8 screws that are longer than the spacers (do not use the screws supplied with the service kit). Loosely thread the cut screws into the tapped holes in the bottom of the manifold. lip the spacers over the screws. This will keep the spacers in line until you are ready to install the supplied screws. When you are ready to install the supplied screws, remove the cut screws. Ask an assistant to help you tilt the unit and support it while you replace the screws and washers V

9 B-7 8. Apply thermal compound to the RTD and thermostat and install them on the side of the tank. 9. Reconnect the ground wire (if present) to the tank. 0. If the unit was attached to a support platform, anchor it to the platform now.. Lay the tank strainer in the bottom of the tank. 2. Install a new tank gasket and secure the tank cover to the tank. NOTE: You should replace the tank gasket any time the tank cover is separated from the tank. 3. wing the wire harness and hose-end panel into position and secure the hose-end panel with the screws you removed earlier. 4. Make sure the air-line adapter is securely inserted in the recessed area on the inside of the hose-end panel. ecure the adapter with the screws you removed earlier. 5. Install the pump air pressure regulator and connect the incoming air line to the regulator. 6. Install the tank lid assembly using the screws you removed earlier. 7. Install the unit s front and back panels. Restoring the Unit to Normal Operation Follow this procedure to reinstall the pump and restore the unit to normal operation.. Install the pump. Refer to Pump Installation in the Hydraulics section. 2. Install and secure the pump cover. 3. Return the pump air pressure to the normal operating setting. 4. Remove the lock-out and restore power to the unit V
