1.INTRODUCTION
Advantages
World-leading energy efficiency - COP of 4.66*
With its best in class COP performance, Estía air to water heat pump system delivers more heating
power with less energy consumption.
Estía uses high quality components and material which contribute to the overall savings in energy
consumption.
With the Toshiba advanced inverter, Estía air to water heat pump system only delivers the heating
capacity required; thus consuming only the necessary electricity.
The hot water temperature is also optimized thanks to Toshiba advanced control depending on
the outside air temperature. The milder outside, the air-to-water systems automatically produces
lower water temperature to anticipate decreased needs of space heating. The same control logic
allows to anticipate as well increasing heating needs when weather conditions become extreme;
this overall temperature management gives the best conditions of comfort.
All this saving has a positive impact on the personal electricity bill and the whole community by
reducing the CO2 emissions in the atmosphere.
Easy to install
*11kW model
Environment conscious
Quick and easy to install. The hydro module
unit can be placed safely in the most suitable
place within the house.
There’s no need for chimney or underground
captors which require additional works on site.
The compact outdoor unit can be placed anywhere outside the
house or on a balcony, thanks to extensive piping options.
One system, multiple
solutions
1
The use of Toshiba Estía heat pump contribute
to the reduction of global CO2 emissions in the
atmosphere and limit the use of fossil fuels or
other non-renewable energy primary sources.
Whenever required for maintenance purpose,
all the R410A refrigerant (non ozone depleting) can be
completely sucked back to the outdoor unit through the
powerful embedded Toshiba “pump down” operation.
The right temperature at the
right time
Estía heat pump systems can be used in
combination with different types of emitters:
existing heating low temperature radiators,
floor heating or fan coil units.
It can produce water at different temperatures
for several applications simultaneously.
Toshiba Estía air to water heat pump system operates smoothly
both with low outdoor air temperature down to -20 ˚C in winter
and up to 43 ˚C in the summer season. The system has a unique
anti-ice build-up protection embedded.

PRECAUTIONS 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 trial operation 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.
• Use the specified electrical cables, fixing securely at all terminations.
• Earth wire connections.
• Install an earth leakage breaker without fail.
Incomplete grounding can cause electric shock.
Do not ground wires to gas pipes, water pipes, lightning rods or telephone cable ground wires.
• 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 input 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.
11 and 14 kW 18 L/minute or more
8 kW 13 L/minute or more
If the flow rate becomes less than the minimum, the protective device is activated to stop operation.
Ensure the flow rate with a bypass valve, etc. when you use a flow rate valve for the Hydro Unit.
• Do not drive water by power other than the pump built in the Hydro Unit.
• The backup heater operates supplementarily to exert a prescribed capacity when the heat pump cannot exert its
capacity at a low outside temperature.
• Install the Hydro Unit and water pipes in a place in which they do not freeze.
• Make the water circuit closed. Never use it as an open circuit.
• Circulating water must be 20 liters or more. If total water amount is not enough, the unit may not function fully
due to protective operation.

Refrigerant Piping
WARNING
• THIS SYSTEM ADOPTS HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY THE OZONE LAYER.
• The characteristics of R410A refrigerant are: ease to absorb water, oxidizing membrane or oil, and its pressure is
approximately 1.6 times higher that of R22. Accompanied with the new refrigerant the oil has also been changed.
Therefore during installation work prevention of the invasion of water, dust, former refrigerant or oil is of a paramount
importance.
To prevent the charging of incorrect refrigerants into the system the service valve connection ports have also
increased in size.
• The use of R410A tools is required for correct installation of the system.
• The use of the correct pipe sizes and wall thicknesses of copper pipe work is required for the correct installation of
the system.
CAUTION
•
•
•
•
•
Ensure all refrigerant pipes are protected from the invasion of dust and water.
Ensure all pipe work connections are tightened to the required torque settings detailed in this section.
Perform an air tight using Oxygen Free Nitrogen (OFN) only.
Evacuate the air in the pipe work using a vacuum pump.
Check for refrigerant gas leaks at all connections throughout the pipe work.
NOTE
The Air to Water Heat Pump system uses R410A refrigerant. It is important that copper pipes used for refrigerant
piping have the following wall thickness:
• 0.8 mm for Ø6.4 mm, Ø9.5 mm and Ø12.7 mm
• 1.0 mm for Ø15.9 mm

• After the installation work, perform a trial operation to check for any problem.
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 the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the Air to Water Heat Pump.
Inappropriate installation may result in water leakage, electric shock or fire.
• Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
• Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
Use an exclusive power circuit for the Air to Water Heat Pump. Use the rated voltage.
• Connect the connecting wire correctly.
If the connecting wire is connected in a wrong way, electric parts may be damaged.
• When moving the Air to Water Heat Pump for the installation into another place, be very careful not to enter
any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally high
and it may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock
switches.
• After unpacking the unit, examine it carefully if there are possible damage.
• Do not install in a 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 according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the Air to Water Heat Pump hydro unit is installed in a small room, provide appropriate measures to
ensure that the concentration of refrigerant leakage occur in the room does not exceed the critical level.
• Tighten the flare nut with a torque wrench in the specified manner.
Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in
refrigerant leakage.
• Wear heavy gloves during the installation work to avoid injury.
• Install the Air to Water Heat Pump securely in a location where the base can sustain the weight adequately.
• Perform the specified installation work to guard against an earthquake.
If the Air to Water Heat Pump is not installed appropriately, accidents may occur due to the falling unit.

8. OUTDOOR UNIT INSTALLATION MANUAL
WARNING
• When the Air to Water Heat Pump cannot cool or heat water well, contact the dealer from whom you
purchased the Air to Water Heat Pump as refrigerant leakage is considered as the cause.
In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair.
The refrigerant used in the Air to Water Heat Pump is harmless.
Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in
the room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been
completely repaired.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the Air to Water Heat Pump 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 the installation work before operating the Air to Water Heat Pump.
If the compressor is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the
refrigeration cycle is overpressurized, which may cause a burst or injury.
• For the refrigerant recovery work (collection of refrigerant from the pipe to the compressor), stop the
compressor before disconnecting the refrigerant pipe.
If the refrigerant pipe is disconnected while the compressor is working with the valve open, the compressor sucks air
and the refrigeration cycle is overpressurized, which may cause a burst or injury.
CAUTION
New Refrigerant Air to Water Heat Pump Installation
• THIS AIR TO WATER HEAT PUMP ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT
DESTROY OZONE LAYER.
• The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also
been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does
not enter the refrigerating cycle.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of
the main unit and installation tools are changed from those for the conventional refrigerant.
• Accordingly the exclusive tools are required for the new refrigerant (R410A).
• For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not
enter.
To Disconnect the Appliance from Main Power Supply
• This appliance must be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm.
• The installation fuse 25 A (All type fuse can be used) must be used for the power supply line of this unit.

• The R410A refrigerant is more susceptible to impurities such as water, oxide membrane, oils, and fats. With the
adoption of the new refrigerant, refrigerating oil has also been changed.
Be careful so that water, dust, conventional refrigerant, and/or conventional refrigerating oil do not enter the
refrigerating cycle of the new refrigerant Air to Water Heat Pump.
• To prevent different refrigerant or refrigerating oil being mixed, the sizes of the charging port of the unit and the
installation tool connecting sections are different from the conventional refrigerant. Accordingly the following
exclusive tools are required for the new refrigerant R410A.

Flaring
1. Cut the pipe with a pipe cutter.
Be sure to remove burrs that may cause gas
leak.
2. Insert a flare nut into the pipe, and then flare the
pipe.
Use the flare nuts supplied with the Air to Water
Heat Pump or those for R410A.
Insert a flare nut into the pipe, and flare the pipe.
As the flaring sizes of R410A differ from those of
refrigerant R22, the flare tools newly manufactured
for R410A are recommended.
However, the conventional tools
B
can be used by adjusting
projection margin of the copper
pipe.
Tightening of Connecting
Part
1. Align the centers of the connecting pipes and fully
tighten the flare nut with fingers. Then fix the nut with
a spanner as shown in the figure and tighten it with
a torque wrench.
2. As shown in the figure, be sure to use two spanners
to loosen or tighten the flare nut of the valve on the
gas side. If you use a single spanner, the flare nut
cannot be tightened to the required tightening
torque.
On the other hand, use a single spanner to loosen or
tighten the flare nut of the valve on the liquid side.

AIR PURGING
Airtight test
Before starting an airtight test, further tighten the spindle valves on the gas side and liquid side.
Pressurize the pipe with nitrogen gas charged from the service port to the design pressure (4.15 Mpa) to conduct
the airtight test.
After the airtight test is completed, evacuate the nitrogen gas.
Air Purge
With respect to the preservation of terrestrial environment, adopt “Vacuum pump” for air purge
(Evacuate air in the connecting pipes) when installing the unit.
• Do not discharge the refrigerant gas to the atmosphere to preserve the terrestrial environment.
• Use a vacuum pump to discharge the air (nitrogen, etc.) remained in the set. If the air remains,
the capacity may decrease.
For the vacuum pump, be sure to use one with backflow preventer so that the oil in the pump
does not backflow into the pipe of the Air to Water Heat Pump when the pump stops.
(If oil in the vacuum pump is put in an Air to Water Heat Pump including R410A, it may cause trouble on the
refrigeration cycle.)
Vacuum pump

AIR 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, push the ZONE1, 2/HOT WATER button on the remote controller.
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 inlet and air outlet 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:
Cooling operation
Hot water

Outdoor temperature
: 10°C to 43°C
Room temperature
: 18°C to 32°C (Dry valve temp.)
