Remove the cover. Connect the pre-assembled inlet and
outlet pipes to the heater
(do not overtighten compression
fittings)

connections. If a leak is present at the compression fitting,
slowly
tighten compression nut until it stops –
do not
overtighten

Open the hot water faucet and run water for minimum
60 seconds and until the flow is continuous and free of air
pockets. Close the faucet and install the aerator (if
supplied).
Failure to install aerator(s) (if supplied) will result in lower-
than-expected heater performance**.
