•This unit requires a qualified installer.
•Do not attempt to repair the unit yourself.
•This unit has no components which you can repair.
•Opening or removing the cover will expose you to dangerous voltages.
•Turning off the power supply will prevent potential electric shock.
WARNING
Installation warnings
• Be sure to ask a dealer or a store specialized in electrical work to install the Air to Water Heat Pump.
• The Air to Water Heat Pump should be installed by a suitably qualified installer, if not; this may lead to problems such as

• Ensure the correct grounding procedures are applied when installing the Air to Water Heat Pump.
• Do not connect the earth wire to gas pipes, water pipes, lightning rods or telephone earth wires.
• Should the Air to Water Heat Pump be improperly grounded, this could lead to an electric shock.
• Serious damage can occur if there is water leak. Therefore, the Hydro Unit is recommended to be installed in a room with
waterproof flooring and drainage systems.
• Products and parts to be used in combination with this product must be specified products and parts that meet prescribed
specifications. If unspecified products or parts are used, a failure, smoke, fire, or electric shock may be caused.
Operation warnings
• Avoid injury or damage to the outdoor unit by never inserting fingers or sticks into the air discharge or air intake of the
outdoor unit, during operation the fans run at a high speed.
• Should you notice something unusual with the Air to Water Heat Pump (such as a burning smell or low heating power),
immediately turn off the main switch and circuit breaker from the main power supply to stop the Air to Water Heat Pump,
and contact the dealer.
• If there is a suspected problem with the operation of the Air to Water Heat Pump, continuous operation is not recommended,
operational failures may lead to machine breakdown, electric shock, a fire, etc.
• Do not spill water or other liquid onto the Hydro Unit.
• If the unit is wet, it could cause an electric shock.
Warnings at movement and repair
• Do not attempt to move or repair the unit yourself.
• Due to the presence of high voltage, removal of any covers may result in an electric shock.
• Should there be any requirements for the Air to Water Heat Pump to be moved, always consult the dealer or qualified

Hydro Unit Owner’s Manual
• When the Air to Water Heat Pump is operated together with a combustion device in the same place, pay careful attention
to ventilation and let fresh air into the room.
Poor ventilation can cause an oxygen shortage.
• When the Air to Water Heat Pump is used in a closed room, pay careful attention to the ventilation of the room.
Poor ventilation can cause an oxygen shortage.
• Do not put a container with water, such as a vase, on the unit, should water enter the unit the result may lead to an electric
shock, this would be due to deterioration in the electric insulation.
• Perform occasional checks to the concrete supports underneath the outdoor unit.
If the base is left damaged or deteriorated, the unit may topple over which could result in possible injury.
• Check from time to time that the unit mounts are not damaged.
If the mounts are left damaged, the unit may drop or topple over, resulting in possible injury.
• Do not wash the unit with water. This could cause an electric shock.
• Do not use alcohol, benzene, thinner, glass cleaner, polishing powder, or other solvent for cleaning the unit because they
can deteriorate and damage the Air to Water Heat Pump.
• Before cleaning the unit, be sure to turn off the main switch or circuit breaker.
• Do not place anything, or step, on the unit, this could cause the unit to fall or topple over which may result in possible injury.
• To achieve maximum performance, the Air to Water Heat Pump must operate within the temperature range specified in the
instructions.
Failure to do so may cause malfunction, break down, or water to leak from the unit.
• Clear away snow before it accumulates on the outdoor unit.
Accumulated snow can lead to malfunction and damage.
• Do not locate other electric appliances or furniture underneath the unit.
Water may drip from the unit, which could lead to rust, unit failure and damage to property.
• Do not allow the obstruction of air flow around the outdoor unit; Do not place any items within the specified installation
service space requirements.
Obstructed air flow can lower performance and cause damage.
• Check for water leaks. In communal housing, leaking water may damage lower floors.
Check for water leaks everyday.
• Do not touch the water pipes, refrigerant pipes, or joints. These may become extremely hot.
Do not drink water produced by the Air to Water Heat Pump.
• After extended use, fresh water may become contaminated by the Hydro Unit, due to deterioration of pipe materials, etc.
• If fresh water contains solid matter, is discolored, turbid or smells, DO NOT DRINK IT.
• Call for equipment inspection immediately.
• Use source water that satisfies water quality standard.
• When the unit will not be used for a long period of time, ask your dealer or a qualified service shop to drain the water inside
the Hydro Unit in order to prevent the water quality from changing.
• When restarting use, ask your dealer or a qualified service shop to charge the unit with water and perform a test run.
• Ask your dealer or a qualified service shop to periodically clean the strainer.
• Ask your dealer or a qualified service shop to confirm that the relief valve is operating correctly.
• Do not hit the manometer, because it is made of glass. It is breakable.

4User maintenance
Periodic maintenance (once a year) is necessary for this product. Consult the installation company.
If a problem occurs, contact the installation company or dealer.
5Air to Water Heat Pump operations and
performance
3 minutes protection function
3-minutes protection function prevents the air to water heat pump from starting for initial 3 minutes after the main
power switch/circuit breaker is turned on for re-starting the air to water heat pump.
Power failure
Power failure during operation will stop the unit completely.
• To restart the operation, we should mention Auto restart function.
Heating characteristics
Defrosting operation
If the outdoor unit is frosted during the heating or hot water supply operation, defrosting starts automatically (for
approximately 2 to 10 minutes) to maintain the heating capacity.
• During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit.
Heating capacity
In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is
called heat pump system. When the outside temperature is too low, it is recommended to use another heating
apparatus in combination with the air to water heat pump.
Attention to snowfall and freeze on the outdoor unit
• In snowy areas, the air intake and air discharge of the outdoor unit are often covered with snow or frozen up.
If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.
• In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for
freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or
poor warming.
Air to water heat pump operating conditions
For proper performance, operate the air to water heat pump under the following temperature conditions:
If air to water heat pump is used outside of the above conditions, safety protection may work.
Cooling operation Outdoor temperature : 10 °C to 43 °C
Room temperature : 18 °C to 32 °C (Dry bulb temp.)
Hot water Outdoor temperature : –20 °C to 43 °C (Heater operation in more than 35 °C)
Room temperature : 5 °C to 32 °C
Heating operation Outdoor temperature : –20 °C to 25 °C
Room temperature : 5 °C to 32 °C
