HEAT EXCHANGER REPLACEMENT Instructions
4. Connect a hose to the Strainer on the Boiler Water side of the piping assembly. Open the
valve on the Strainer and drain the boiler water from the unit. It will be necessary to loosen
a Victaulic coupling by the heat exchanger to allow air into the pipe during draining.
5. Drain the boiler water from the unit.
6. Ensure that the piping above the Victaulic connections is adequately supported.
7. Remove the four (4) Victaulic couplings, the four (4) Pipe Connectors connecting the heat
exchanger to the piping assembly, and the two nuts that connect the heat exchanger to the
mounting bracket.

WARNING!
Depending on the SmartPlate EV model, the heat exchanger weighs
50 to 180 pounds
.
You
must use extreme care when removing the heat exchanger.
Use a strap suitable for such
weight to lift and remove the heat exchanger
.
8. Devise a lifting rig that can lift the heat exchanger without putting any pressure on the
edges of the heat exchanger plates and lift the heat exchanger up and off the unit.
9. To install the replacement heat exchanger, reverse the steps above. Lower the
replacement heat exchanger using a suitable lifting rig onto the heat exchanger mounting
bracket. Ensure it is properly aligned with the Piping Assembly and heat exchanger
mounting bracket. Ensure that the bolts on all four Victaulic couplings are securely
tightened.
