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 o. 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 ecient 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.
