BEFORE ATTEMPTING ANY INSTALLATION, MODIFICATION OR SERVICE OF THIS HEATER,
MAKE SURE THE ELECTRICAL POWER IS DISCONNECTED.
1. The heater’s water INLET and OUTLET are labeled.
Install full flow ball valves to the inlet and outlet pipes and
run water through the inlet pipe into a bucket to purge it of
any debris. Close the inlet ball valve.
2. Make sure the inlet filter screen is present in the inlet
fitting and the inlet and outlet pipes are correctly aligned
with the heater connections to minimize stress on the
heater.
3. Remove the cover. Connect the pre-assembled inlet and
outlet pipes to the heater (do not overtighten compression
fittings) and fully open the inlet and outlet ball valves.
Check the system for water leaks at all plumbing
connections. If a leak is present at the compression fitting,
slowly tighten compression nut until it stops – do not
overtighten.
