POWER SUPPLY CORD
The HPAC 2.0 is shipped from the factory with a Leakage Current Detection Interrupter (LCDI) equipped power
supply cord. The LCDI device meets the UL and US National Electric Code 440.65 requirements for power supply
cord connected air conditioners.
TEST YOUR POWER SUPPLY CORD PRIOR TO INSTALLATION
Plug power supply cord into a grounded three-prong electrical power outlet.
Press TEST (listen for the click; Reset button trips and pops out). This should cut
the power to the HPAC 2.0. If the plug does not trip and the unit stays on, please
contact technical support.
Press RESET (listen for the click; Reset button latches and remains in). The power
supply cord is ready for operation.
The LCDI device is not intended to be used as a switch. Do not
use the TEST and RESET buttons to turn the HPAC 2.0 on and
off. Once plugged in, HPAC 2.0 will operate normally without the
need to reset the LCDI device.
CAUTION
ELECTRICAL SHOCK HAZARD
If the LCDI device fails to trip when tested or if the power supply
cord is damaged, it must be replaced with a new power supply
cord obtained from Ephoca and must not be repaired.

ENERGY-SAVING SUGGESTIONS
The HPAC 2.0 is extremely efficient and features a state-of-the-art inverter compressor. Here are a few energy-saving
tips to keep your HPAC 2.0 running at peak performance and using minimum energy.
zCarefully read and follow the installation instructions.
zAlways keep the filters clean (see Maintenance and Cleaning chapter.)
zHave the HPAC 2.0 professionally inspected and cleaned by an authorized technician every two to three years,
depending on use.
zKeep the doors and windows of the rooms closed while the HPAC 2.0 is operating.
zProper insulation helps your HPAC 2.0 maintain the desired inside temperature.
zDo not let direct sunlight enter the room (use curtains or lower the blinds) while the air conditioner is operating,
using shade wherever possible.
zDo not block the supply and return airflow grilles of the HPAC 2.0; not only will this result in non-optimal
performance of the HPAC 2.0, it may also cause damage and void the warranty.
zKeep window coverings away from the HPAC 2.0 to ensure free air flow.

COOLING MODE
In this cooling mode, the HPAC 2.0 cools and dehumidifies the room. The fan will consistently
operate.
To activate cooling mode press the cooling button.
Use the up and down arrows to set the desired temperature between 61°F and
87°F.
ATTENTION At startup, it can take up to three minutes for the HPAC 2.0 to
start supplying cool air.
TEMPERATURE SETPOINT DISPLAY
When the HPAC 2.0 is turned on, the three digits on the display will show the
desired temperature.
It is possible to set the desired temperature between 61°F and 87°F. The HPAC 2.0
will bring the room to the desired temperature.
NOTICE If the temperature is set too low or too high, it can be unhealthy
and an unnecessary waste of energy.
The HPAC 2.0 will periodically defrost the evaporator coil, if necessary. During the defrosting
phase, the HPAC 2.0 does not supply warm air.
POWER ON/OFF
Power the HPAC 2.0 on or off (standby) by pressing the Power button. The control
system of the HPAC 2.0 is equipped with a memory, so settings will not be lost if
the HPAC 2.0 is turned off or there is a loss of power.
The Power button is used to activate or deactivate the HPAC 2.0 for short time
periods only. In the case of long periods of inactivity, the HPAC 2.0 must be
unplugged from the power grounded three-prong electrical power outlet.

19
HEATING MODE
In heating mode, the HPAC 2.0 heats the room.
To activate heating mode, press the heating button
Use the up and down arrows to set the desired temperature between 61°F and
87°F.
ATTENTION At startup, it can take up to three minutes for the HPAC 2.0 to
start supplying warm air.
The HPAC 2.0 will periodically defrost the evaporator coil, if necessary. During the defrosting
phase, the HPAC 2.0 does not supply warm air.
VENTILATION MODE
In this ventilation mode the fan circulates the air in the room. The fan speed can be adjusted
to Low, Medium and High.
To activate ventilation mode, press the ventilation button.
To adjust the fan speed press the fan speed button until the desired speed is
reached.
ATTENTION The HPAC 2.0 will not cool, heat or remove humidity in this mode.
The HPAC 2.0 will periodically defrost the evaporator coil, if necessary. During the defrosting
phase, the HPAC 2.0 does not supply warm air.

20
DEHUMIDIFICATION MODE
In dehumidification mode, the HPAC 2.0 dehumidifies the room.
To activate dehumidification mode, press the dehumidification button.
This mode is useful during the spring and fall when the temperature is pleasant, but excess
humidity may cause discomfort. This mode ignores both room temperature and fan speed
settings. The fan operates only on low speed. It is normal for the HPAC 2.0 to work
intermittently.
FAN SPEED
Pressing the Fan Speed button will change the speed of the fan in cooling, heating and
ventilation mode. You can choose three fan speeds or automatic.
In Automatic Mode (shown by three speed bars moving up and down on the display), the
onboard microprocessor automatically adjusts the fan speed as needed. The speed will
always be automatically increased and decreased as the room temperature approaches the
set temperature.
To select the fan speed press the Fan Speed button until the desired speed or
mode is reached. The sequence of the button is as follows: Low, Medium, High,
Turbo Power and Automatic.
The higher the speed is set, the better the HPAC 2.0 will perform. The higher the speed of
the fan, the noisier the air conditioner will be.
AUTOMATIC MODE
In this mode, the HPAC 2.0 automatically selects the mode (Cooling or Heating) according
to the temperature setting and adjusts the fan speed.
To activate automatic mode, press the A buton. To deactivate, simply select cool
or heat.
