Test the water source to determine water hardness.  If the water hardness exceeds 7 grains, a suitable water softener should be installed.  Installing a water softener greatly improves chemical action and prevents water spotting on glass, chrome and other washer surfaces.

Don't forget to add R2 or two wire high pressure jump hose to install this unit.

Switch to Viton O-rings and use an insulated wand while operating this hot water heater. Always remember to run cool water through the unit to cool it off before storing for the night.
