Please read all instructions and understand procedures before proceeding. We also offer a several options for rebuilding your heat exchanger. More details available the article titled, "Heat Exchanger Repair Options for Casting Equipment"

• Turn off power at the main breaker and lock out. Use all normal safety procedures when working with electrical equipment.
• Drain heating fluid from Stainless steel heater tank.
• Turn off resin valves.
• Disconnect resin and fluid lines. Note (mark) their location for reassembly.

• Remove heat exchanger.

• Measure the thickness of the exchanger at the plates and record this number for reassembly.
  • Typically 1.72" for 12 plate (14 including front and back end plates) exchanger.
  • Typically 3.125" for 24 plate (26 including front and back end plates) exchanger.
• Unscrew the large bolts by taking ½ turn on each bolt until loose.

• Carefully remove the large blue end plate.
  

• Remove the stainless plates as a set and permanently mark the plates as shown for reassembly.

• Carefully separate the resin side of the plates. Do not cut or nick the black gasket that is attached to the plate. The fluid sides may not want to come apart and do not require cleaning.

• A smooth round rod may help in disassembly.

• Disassemble plates.

• Use a plastic scraper to remove the congealed resin in the groves of the plates being careful not to damage the gaskets on the edged of the stainless steel plates.

• Use styrene to wipe out the resin left on the plates.

• Reassemble plates in their original position.

• Replace the large bolts and tighten each of them ½ turn at a time until the two large blue plates are returned to the thickness that was measured before disassembly.
• Reinstall in machine and connect fluid and resin lines to original positions.
• Refill the heater fluid and open the resin valves. Turn on power to machine.
• Test and look for resin or fluid leaks. Be sure to check the first run of matrix for heater fluid in the mix.
