– see
Figure 4.3. The tubing can be placed down the back side of the unit. The
tubing should be secured to the wall or floor to prevent it from moving during
the purging cycle.
During startup of the unit, it is strongly recommended
to test the purge valve to confirm connections are free of leaks and the
water discharges to drain.
Step 4:
Caution: do not allow the inside of the unit to get wet. Before
opening the water supply, double check all connections and taps. Slowly turn
on the water supply, vent out trapped air and check for leaks. If leaks exist,
investigate the cause and repair before plugging in the unit.

connections for leaks (specifically at flexible hoses if purchased). Repeat this
procedure periodically.
