Component Identification Component Identification Double Wall Hoppers Mounted on Side of Frame R H A C H J J G D K D N P L E M B M E F FIG.
Overview Overview Double wall hoppers (D) can be mounted on the back or side of the frame (A) to gravity feed spray material to the Xtreme lower (B). Feed pumps (H) and agitators (J) can be mounted on top of the hoppers to pressure feed spray material directly to the pump. XM sprayers are not approved for use in hazardous locations unless the base model, all accessories, all kits, and all wiring meet local, state, and national codes. A strainer inside the hopper (D) prevents objects larger than 1/4 in.
Installation Installation Hopper mounting kit 256259 allows the hoppers (D) to mount on the sides or back of the frame (A). 1. Mount hoppers (D) on sides of the frame (A). See FIG. 3. a. Remove four screws (306) holding solvent pump bracket (307) to mounting plate (308). Leave pump attached to bracket. Remove pump and bracket. a. Attach main bracket (101) to frame (A) with screws (107). A 101 308 306 307 107 FIG. 4: Remove Solvent Pump FIG. 3: Sides of Frame b. b.

Installation Optional Accessories 4. Install bushing (302) in top of wiring outlet. Route power cable (303) through bushing (302). See Accessories page 28 for a list of all accessories that can be used with double wall hoppers. D 302 Immersion Heater Kit 256257 The immersion heater (L) is only approved for non-explosive atmosphere applications. Using the immersion heater in hazardous locations, or explosive atmospheres, may cause ignition or explosion.
Installation 8. Set thermostat knob (TK) to desired spray material conditioning temperature. Align temperature setting to set point (SP). NOTE: Set point (SP) is a “V” notch in the metal bracket at the top of the thermostat dial. Maximum setting is 140°F (60°C). 303 SP TK BA BB 302 L HC 303 FIG. 14: Connect Immersion Heater FIG. 15: Immersion Heater Power Cables 9. Install immersion heater cover (HC) with screws (HS). See FIG. 13. 11.
Setup Setup 1. Remove the large A or B label from the label sheet (24) and apply to front face of the appropriate hopper to help avoid filling the wrong materials and causing cross-contamination. 3. Connect other end of recirculation hose to recirculation valve (V) on XM sprayer. R 24 R V FIG. 16: Apply Label 2. Remove the small A or B from the label sheet (24) and apply on lid. FIG. 18: Recirculation Hose and Recirculation Valve 4. Repeat for second hopper.
Setup Fill Heating Fluid Fill the hopper’s outer jacketed area with oil or a 50% water and 50% ethylene glycol mixture to heat your spray material. The double wall hopper design prevents the spray material from losing heat during downtime and overnight. NOTICE Algae can form inside the outer jacketed area if you are using only water to heat your spray material. Always add ethylene glycol to the water to prevent the formation of algae.
Setup Fill Spray Material Left Side Shown Condition materials prior to adding to hoppers. Ensure resin materials are thoroughly agitated, homogenous, and pourable prior to adding to hopper. Stir hardeners back into suspension prior to adding material to hopper. (45°) 1. Disconnect spring strap (7) from front post and remove lid (1c). Keep connected to lanyard (10). 10 Open Port 7 FIG. 21: Orientation of Venting Fittings 5. Install plug (6) in opposite port and torque to 20-30 ft-lbs (27-41 N•m).
Operation Operation Startup Flush Hopper 1. Ensure that the outer jacketed area is filled with water mixture or oil and the accessories are correctly installed. 1. Drain Spray Material. See page 19. 2. Follow Setup procedure in manual 312359. 3. See manual 312359 for testing material and operation instructions before spraying material. 2. Flush hoppers and fluid inlet assemblies (F) with compatible solvent before switching materials or cleaning hopper (D). See Flushing section in manual 312359. 3.
Maintenance Maintenance Drain Heating Fluid 1. Turn off all heaters and allow heating fluid to cool for a minimum of 8 hours. Check Heating Fluid Level Gradual fluid evaporation can occur, therefore, check the level of heating fluid monthly. 1. Remove plug (6). 2. Place either a 1-gallon (4-liter) or 3-gallon (7-liter) pail directly beneath drain plug (37). NOTE: Only 1-gallon (4-liter) pails fit beneath drain plug if hoppers are mounted on the back of the frame. 2.
Maintenance Drain Spray Material 206 1. Flush and Shutdown XM sprayer. See XM operation manual. 2. Turn off all fluid heaters (S) and allow heating fluid to cool for a minimum of 8 hours. 3. Place a clean 1 gallon (4 liter) pail directly beneath union (208) and ball valve (206). FIG. 27: Drain Hopper 4. Close ball valve (206) and open union (208) with wrench. 8. Use additional pails as necessary until all material is drained. 9. Close ball valve (206) and use two wrenches to retighten union (208).

Repair Remove Hopper Replace Gaskets 1. Check Heating Fluid Level. See page 18. The following procedure applies to both the hopper gaskets (13) and hopper lid gasket (12). 2. Drain Spray Material. See page 19. 3. Disconnect swivel fitting (202). See FIG. 29. 1. Remove old gasket and residual adhesive using MEK solvent. 4. If a transfer pump (H) or agitator (J) is mounted to the hopper: 2. Clean groove in hopper using isopropyl alcohol. Let air dry. a. Relieve pressure. See manual 312769. b.
Troubleshooting Troubleshooting Problem Cause Lid does not properly seal on hopper. Material build up. Damaged gasket. Solution Remove built up material from gasket. Replace as necessary. Material leaking between cover and hopper. Gasket is not sealed properly. Check for built up material on gasket. Replace as necessary. Algae in water. Ethylene glycol was not added to water. Drain fluid. Add 50/50 water and ethylene glycol mixture in outer cavity Immersion heater no longer heating.
