4Precautions for safety
General safety precautions
Ensure that all Local, National and International regulations are satisfied.
• Read the “Precautions for safety” carefully before installation.
• The precautions described below include the important items regarding safety – Observe
them without fail.
• After the installation work has been completed, perform a test run to check for any problems.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before unit maintenance.
• Ask the customer to keep the Installation Manual along with the Owner’s Manual.
Refrigerant precautions
• If a refrigerant leak is suspected contact the dealer who supplied the system, in the case of a
recharge of refrigerant ask service personnel for details of the leak and confirmation of the
repairs completed.
The refrigerant used in the system is harmless.
• Generally the refrigerant does not leak, however, if the refrigerant should leak into a room and
a heater or stove burner in the room is lit, toxic gas may be generated.
• Do not install the system in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and stays around the unit a fire may occur.
• Install the refrigerant pipe securely during installation and before operation.
If the compressor is operated with no pipe work connected and valves open the compressor
will suck air which would result in over pressurization of the system which may result in
bursting or injury.
Observe the same precautions for refrigerant recovery work (pump back procedure to outdoor
unit) and do not disconnect pipe work until refrigerant is recovered and valves closed.
WARNING
Installation precautions
• Ask an authorized dealer or qualified installation professional to install/maintain the Air to
Water Heat Pump System.
Inappropriate installation may result in water leaks, electric shock or fire.
• Electrical work must be performed by a qualified electrician in accordance with the installation
manual.
An inappropriate power supply capacity or installation may result in fire.
• When completing any electrical works to the system ensure that all Local, National and
International regulations are satisfied.
Inappropriate grounding may result in electric shock.
• Ensure all electrical cables, used for the ESTIA installation, comply with all Local and National
regulations. Check all electrical terminations are secure and tight.
• Earth wire connections.
• Install an earth leakage breaker without fail.
Incomplete grounding can cause electric shock.
Do not earth wires to gas pipes, water pipes, lightning rods or telephone cable earth wires.

Hydro Unit Installation Manual
• This unit must be connected to the main power supply using a circuit breaker or switch with a
contact separation of at least 3 mm.
• Be sure to turn off all main power supply switches or the circuit breaker before starting any
electrical work.
Ensure all power switches are off, failure to do so can cause electric shock.
Use an exclusive power circuit for the Air to Water Heat Pump system using the rated voltage.
• Ensure correct connection of interconnecting wire between Outdoor Unit and Hydro Unit.
Incorrect connection of the interconnecting cable may result in the damage of electrical parts.
• Ensure refrigeration system remains sealed to external gases and air.
Should air or other gases contaminate the refrigeration circuit, high system pressures could
result in burst pipes and injuries.
• Do not modify or bypass any of safety guards or switches in this system.
• After unpacking the outdoor unit, examine the unit carefully for any possible damage.
• Do not install in any place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly in accordance with the installation manual.
Inappropriate installation may result in water leaks, electric shock or fire.
• Tighten all flare nuts with a torque wrench in the specified manner.
Excessive tightening of the flare nut may result in cracking of the pipe work or flare nut which
may result in a refrigerant leakage.
• Wear heavy duty gloves during installation work to avoid injury.
• Install the outdoor unit securely in a location where the base can sustain the weight
adequately.
• In enclosed areas, if the refrigerant leaks during installation vacate and ventilate immediately.
• After installation is complete ensure and confirm that refrigerant does not leak.
If refrigerant leaks into a room and flows near a fire source noxious gas may be generated.
• Do not block any drain hoses. Hoses may come off and electric shocks may occur.
• Do not hit the manometer, because it is made of glass. It is breakable.

Notes on system design
• The inlet water temperature to the Hydro Unit must be 55 °C or less.
Especially, be careful when there is an external heating source such as a boiler.
When hot water over 55 °C returns, it may result in a failure of the unit or water leakage.
• The flow rate of the circulating water must meet the following range.
14 kW 18 L/minute or more
8 kW 13 L/minute or more
4.5 kW 10 L/minute or more
If the flow rate becomes less than the minimum, the protective device is activated to stop the
operation.
To ensure the minimum flow rate of the water system, install a bypass valve on one water
circuit. Please note this circuit must contain a minimum of 20 liters. If total water amount is not
enough, the unit may not function fully due to protective operation.
• Do not drive water by power other than the pump built in the Hydro Unit.
• The back up heaters, in the hydro unit, are designed to assist the heat pump during periods
of low ambient conditions.
• Ensure the Hydro unit and the connecting water pipes are installed in a location that is not
exposed to low ambient temperatures which could result in the water circuit freezing.
• The system operation is designed around a closed water circuit. Do not use an open circuit
design.
• Please turn on the main power supply to up to 12 hours before the start of the operation, and
don’t turn off the power all the time during the period of use.
