2. “AutoC”*
Controlling heat production
HM270V selects operating mode automatically (cooling
can also be selected now) by the outdoor temperature. This
means that the operating mode switches between
“Heating”, “Cooling” and “Hot water”.
Normally, the heat pump heats the water (heating medium) to
the temperature required at a certain outdoor temperature. This
occurs automatically on the basis of the collected temperature
values from the outdoor sensor and sensors on the lines to the

The integrated water heater is a coil model and is heated by
circulating water, which is heated by the heat pump.
Extra Hot Water
During “normal” consumption it is enough to run the heat
pump to supply the different tapping points of the house with
hot water. The temperature of the hot water in the water heater
then varies between the set values.

Maintenance
HM270V and FDCW100VNX require minimal maintenance
after commissioning.
Emptying the vessel
Contact your installer if the vessel in HM270V needs emptying.
Hydrolution contains many components and is why monitoring
functions are integrated to help you.
Maintenance of FDCW100VNX

necessary.
Checking the safety valves in HM270V
HM270V has been equipped with a safety valve for the water
heater as well as a safety valve for the climate system by the

Hot water heater safety valve
The water heater’s safety valve sometimes releases a little
water after hot water usage. This is because the cold water,
which enters the heater to replace the hot water, expands when
heated causing the pressure to rise and the safety valve to open.
$OVRFKHFNWKHZDWHUKHDWHUVDIHW\YDOYHUHJXODUO\7KH
appearance and location of the safety valve differs between
different installations. Contact your installer for information.

4) On-site piping work
IMPORTANT
● Take
care so that installed pipes may not touch components within a unit. If touching with
an internal component, it will generate abnormal sounds and/or vibrations.
How to remove the service panel
First remove the five screws ( mark) of the service panel and push it down into the
direction of the arrow mark and then remove it by pulling it toward you.
Catch
● The
pipe can be laid in any of the following directions: side right, front, rear and downward.
● Remove a knock-out plate provided on the pipe penetration to open a minimum necessary area and attach an
edging material supplied as an accessory by cutting it to an appropriate length before laying a pipe.
● Carry out the on site piping work with the operation valve fully closed.
● Give sufficient protection to a pipe end (compressed and blazed, or with an adhesive tape) so that water or foreign
matters may not enter the piping.
● Bend a pipe to a radius as large as practical.(R100∼R150) Do not bend a pipe repeatedly to correct its form.
● Flare connection is used between the unit and refrigerant pipe. Flare a pipe after engaging a flare nut onto it.
Flare dimensions for R410A are different from those for conventional R407C. Although we recommend the use
of flaring tools designed specifically for R410A, conventional flaring tools can also be used by adjusting the
measurement of protrusion B with a protrusion control gauge.

① Although outdoor and indoor units themselves have been tested for air tightness at the factory, check the connecting pipes after the installation work for air tightness from the operation
valve’s check joint equipped on the outdoor unit side. While conducting a test, keep the operation valve shut all the time.
a) Raise the pressure to 0.5 MPa, and then stop. Leave it for five minutes to see if the pressure drops.
b) Then raise the pressure to 1.5 MPa, and stop. Leave it for five more minutes to see if the pressure drops.
c) Then raise the pressure to the specified level (4.15 MPa), and record the ambient temperature and the pressure.
d) If no pressure drop is observed with an installation pressurized to the specified level and left for about one day, it is acceptable. When the ambient Temperature fall 1℃, the pressure also
fall approximately 0.01 MPa. The pressure, if changed, should be compensated for.
e) If a pressure drop is observed in checking e) and a) – d), a leak exists somewhere. Find a leak by applying bubble test liquid to welded parts and flare joints and repair it. After repair,
conduct an air-tightness test again.
② In conducting an air-tightness test, use nitrogen gas and pressurize the system with nitrogen gas from the gas side. Do not use a medium other than nitrogen gas under any circumstances.

indicator will rise.
Check the system for a leaky point and then
draw air to create a vacuum again.
Vacuuming begins
Pay attention to the following points in addition to the above for the
R410A and compatible machines.
Vacuuming completed
○To prevent a different oil from entering, assign dedicated tools, etc. to each
refrigerant type. Under no circumstances must a gauge manifold and a charge
hose in particular be shared with other refrigerant types (R22, R407C, etc.).
○Use a counterflow prevention adapter to prevent vacuum pump oil from
entering the refrigerant system.
Run the vacuum pump for at least one hour after the vacuum
gauge shows -101kPa or lower. (-755mmHg or lower)
Confirm that the vacuum gauge indicator does not rise even if
the system is left for one hour or more.
Vacuum gauge check
Fill refrigerant
7) Refrigerant charge
(1) Since this unit contains 2.9kg refrigerant including the amount for piping of 12m, it is not necessary to charge addifional refrigerant for piping on site.
● To
charge refrigerant again to the system, recover refrigerant from the system first and then charge the same volume as initial charge.
(2) Charging refrigerant
● Since
R410A refrigerant must be charged in the liquid phase, you should charge it, keeping the container cylinder upside down or using a refrigerant cylinder equipped with a siphon tube.
refrigerant always from the liquid side service port with the operation valve shut. When you find it difficult to charge a required amount, fully open the outdoor unit valves on both liquid and gas sides and charge refrigerant from the
gas (suction) side service port, while running the unit in the cooling mode. In doing so, care must be taken so that refrigerant may be discharged from the cylinder in the liquid phase all the time. When the cylinder valve is throttled down
or a dedicated conversion tool to change liquid-phase refrigerant into mist is used to protect the compressor, however, adjust charge conditions so that refrigerant will gasify upon entering the unit.
● In charging refrigerant, always charge a calculated volume by using a scale to measure the charge volume.
● When refrigerant is charged with the unit being run, complete a charge operation within 30 minutes. Running the unit with an insufficient quantity of refrigerant for a long time can cause a compressor failure.
● Charge
8) Insulation on piping
(1) Dress refrigerant pipes (both gas and liquid pipes) for heat insulation and prevention of dew condensation.
(2) Use a heat insulating material that can withstand 120℃ or a higher temperature. Poor heat insulating capacity can cause heat insulation problems or cable deterioration.
- Improper heat insulation/anti-dew dressing can result in a water leak or dripping causing damage to household effects, etc.
- All gas pipes must be securely heat insulated in order to prevent damage from dripping water that comes from the condensation formed on them during a cooling operation or personal injury from burns because their surface can reach quite a
high temperature due to discharged gas flowing inside during a heating operation.
- Wrap indoor units’ flare joints with heat insulating parts (pipe cover) for heat insulation (both gas and liquid pipes).
- Give heat insulation to both gas and liquid side pipes. Bundle a heat insulating material and a pipe tightly together so that no gaps may be left between them and wrap them together with a connecting cable by a dressing tape.
- Both gas and liquid pipes need to be dressed with 20 mm or thicker heat insulation materials above the ceiling where relative humidity exceeds 70%.
