Residenal Hybrid Electric Heat Pump Water Heater Use and Care Guide • 17
INSTALLATION
1
Understand how to use the
User Interface Module to set
the various modes and
funcons.
2
Hybrid Mode is the recom-
mended Operang Mode.
Understand the various
Operang Modes and which mode may
be best, based on ambient temperature
and hot water demands.
3
Understand the importance of
roune inspecon/ mainte-
nance of the condensate drain
pan and lines. This is to prevent any
possible drain line blockage resulng in
the condensate drain pan overowing.
If water is coming from the
overow slot of the condensate drain
access cover, this indicated that both
condensate drain lines may be blocked
and immediate acon is required.

The Installaon Instrucons
and Use and Care Guide should
be kept with the water heater
for reference.
Water Temperature Ad-
The water temperature can be
adjusted from 95°F / 35°C to 150°F /
65.5°C. Use the Up and Down Buons
on the front panel to
set the desired temperature (gure 26,
page 19). The seng temperature will
blink on the display, press Mode/Enter
buon to conrm.
The water temperature can be
adjusted quickly by pressing the
“Temperature Up” buon and holding
for three seconds.
Before aempng to adjust
the thermostat, read the “Water
Temperature Regulaon” secon. If
the instrucons are not clear, contact a
qualied person.
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 operaonal
mode when nished.
-
The operang modes can be changed
sequenally by pressing the Mode/
Enter buon (Figure 26, page 19). The
Operaon Mode Indicaon 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 Eciency or
Hybrid mode, during normal usage,
the unit will operate the heat pump
for maximum eciency. In the Hybrid
mode during periods when 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 transion is seamless
and will go unnoced.
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°C to 120°F / 48°C
ambient temperature. At ambient
temperatures lower than 45°F / 7°C
and greater than 120°F / 48°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 air and
water temperatures return to the safe
operating range of the heat pump.
Hybrid Mode -
This is the default, recommended
setting, combining high energy
efficiency with reduced recovery time.
This mode uses the heat pump as the
primary heating source. One of the
heating elements (upper or lower)
will provide supplementary heating if
demand exceeds a predetermined level
so that the set point temperature can
be recovered more quickly.
