1
Understand how to use the
User Interface Module to set
the various modes and
func ons.
2
Hybrid Mode is the recom-
mended Opera ng Mode.
Understand the various
Opera ng Modes and which mode
may be best, based on ambient
temperature and hot water demands.
3
Understand the importance of
rou ne inspec on/ mainte-
nance of the condensate drain
pan and lines. This is to prevent any
possible drain line blockage resul ng in
the condensate drain pan over
fl
owing.
NOTE:
If water is coming from the
over
fl
ow slot of the condensate drain
access cover, this indicated that both
condensate drain lines may be blocked
and immediate ac on is required.

The Installa on Instruc ons
and Use and Care Guide
should be kept with the water
heater for reference.
Water Temperature Ad-
justment
The water temperature can be
adjusted from 95°F / 35°C to 140°F /
60°C. Use the Up and Down Bu ons
on the front panel
to set the desired temperature (see
fi
gure 26 on page 19). The se ng
temperature will blink on the display,
press Mode/Enter bu on to con
fi
rm.
The water temperature can be
adjusted quickly by pressing the
“Temperature Up” bu on and holding
for three seconds.
NOTE:
Before a emp ng to adjust
the thermostat, read the “Water
Temperature Regula on” sec on. If
the instruc ons are not clear, contact
a quali
fi
ed person.
NOTE:
For increased water demand,
switching (temporarily) to Hybrid
Mode or Electric Mode will decrease
the recovery/re-heat me. Be sure to
switch back to the desired opera onal
mode when
fi
nished.
Opera ng Mode De-
scrip ons
The opera ng modes can be changed
sequen ally by pressing the Mode/
Enter bu on (Figure 26, page 19). The
Opera on Mode Indica on Light will
turn on when the relevant mode is
selected.
This unit is equipped with technology
that senses the hot water demand
from the unit. While in E
ffi
ciency or
Hybrid mode, during normal usage,
the unit will operate the heat pump
for maximum e
ffi
ciency. In mes that
the water usage is above normal, this
unit has the ability to use one element
(upper or lower) and the heat pump
simultaneously to help improve
recovery. This transi on is seamless
and will go unno ced.
Efficiency Mode -
Provides the highest efficiency and
lowest cost operation by using only
the heat pump for heating. Recovery
time and efficiency will vary with
ambient temperature and relative
humidity. Efficiency will be greatest,
and recovery quickest, when both
are high. At lower temperatures and
relative humidity levels, efficiency
will be lower and recovery will take
longer. Heat pump operation is
allowed between 45°F / 7.2°C to
120°F / 48.8°C ambient temperature.
At ambient temperatures lower
than 45°F / 7.2°C and greater than
120°F / 48.8°C, the heat pump will
not operate. Similarly, if the water
temperature in the tank is less than
59°F / 15°C, the heat pump will
not operate. The unit will operate
in electric mode until ambient and
water temperatures return to the safe
operating range of the heat pump.
