Safety Precautions• The precautions described herein are classified as WARNING and CAUTION. They both contain important
information regarding safety. Be sure to observe all precautions without fail.• Meaning of WARNING and CAUTION notices
WARNING.....Failure to follow these instructions properly may result in personal injury or loss of life.
CAUTION......Failure to observe these instructions properly may result in property damage or personal injury, which may be serious depending on the circumstances.
• The safety marks shown in this manual have the following meanings:
• After completing installation, conduct a trial operation to check for faults and explain to the customer how to operate the domestic hot water heat pump and take care of it with the aid of the operation manual.
• The English text is the original instruction. Other languages are translations of the original instructions.
Be sure to follow the instructions. Be sure to establish an earth connection. Never attempt.
WARNING• Ask your dealer or qualified personnel to carry out installation work.
Do not attempt to install the domestic hot water heat pump yourself. Improper installation may result in water leakage, electric shocks or fire. • Install the domestic hot water heat pump in accordance with the instructions in this installation manual.
Improper installation may result in water leakage, electric shocks or fire. • Be sure to use only the specified accessories and parts for installation work.
Failure to use the specified parts may result in the unit falling, water leakage, electric shocks or fire. • Install the domestic hot water heat pump on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injury. • Electrical work must be performed in accordance with relevant local and national regulations and with instructions
in this installation manual. Be sure to use a dedicated power supply circuit only. Insufficiency of power circuit capacity and improper workmanship may result in electric shocks or fire.
• Use a cable of suitable length. Do not use tapped wires or an extension lead, as this may cause overheating, electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal connections or wires. Improper connections or securing of wires may result in abnormal heat build-up or fire.
• When wiring the power supply and connecting the wiring between the domestic hot water tank and the outdoor unit, position the wires so that the control box lid can be securely fastened. Improper positioning of the control box lid may result in electric shocks, fire or over heating terminals.
• If refrigerant gas leaks during installation, ventilate the area immediately. Toxic gas may be produced if the refrigerant comes into contact with fire.
• After completing installation, check for refrigerant gas leakage.Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source of fire, such as a fan heater, stove or cooker.
• When installing or relocating the domestic hot water heat pump, be sure to bleed the refrigerant circuit to ensure it is free of air, and use only the specified refrigerant (R410A). The presence of air or other foreign matter in the refrigerant circuit causes abnormal pressure rise, which may result in equipment damage and even injury.
• During installation, attach the refrigerant piping securely before running the compressor. If the refrigerant pipes are not attached and the stop valve is open when the compressor is run, air will be sucked in, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• During pump-down, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the refrigeration cycle, which may result in equipment damage and even injury.
• Be sure to earth the domestic hot water heat pump. Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may result in electric shocks.
• Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in electric shocks or fire.
CAUTION• Do not install the domestic hot water heat pump at any place where there is a danger of flammable gas
leakage.In the event of a gas leakage, build-up of gas near the domestic hot water heat pump may cause a fire to break out.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and insulate piping to prevent condensation. Improper drain piping may result in indoor water leakage and property damage.

5. Evacuating the air with a vacuum pump and checking gas leakage WARNING
• Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.• When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.• R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.• Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerants may damage the vacuum
pump or the unit.
• When piping work is completed, it is necessary to evacuate the air with a vacuum pump and check for gas leakage.
• If using additional refrigerant, perform air evacuating from the refrigerant pipes and the domestic hot water tank using a vacuum pump, then charge additional refrig-erant.
• Use a hexagonal wrench (4mm) to operate the stop valve rod.• All refrigerant pipe joints should be tightened with a torque wrench at the specified
tightening torque.
*1. Pipe length vs. vacuum pump run time.
*2. If the compound pressure gauge pointer swings back, refrigerant may have water content or a loose pipe joint may exists. Check all pipe joints and retighten nuts as needed, then repeat steps 2) through 4).
1) Connect projection side of charging hose (which comes from gauge manifold) to gas stop valve’s service port.
2) Fully open gauge manifold’s low-pressure valve (Lo) and completely close its high-pressure valve (Hi).(High-pressure valve subsequently requires no operation.)
3) Do vacuum pumping and make sure that the compound pressure gauge reads –0.1MPa (–76cmHg).*1
4) Close gauge manifold’s low-pressure valve (Lo) and stop vacuum pump.(Keep this state for a few minutes to make sure that the compound pressure gauge pointer does not swing back.)*2
5) Remove caps from liquid stop valve and gas stop valve.
6) Turn the liquid stop valve’s rod 90 degrees counterclockwise with a hexagonal wrench to open valve. Close it after 5 seconds, and check for gas leakage.Using soapy water, check for gas leakage from the domestic hot water tank flare and outdoor unit’s flare and valve rods.After the check is complete, wipe all soapy water off.
7) Disconnect charging hose from gas stop valve’s service port, then fully open liquid and gas stop valves.(Do not attempt to turn valve rod beyond its stop.)
8) Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques.

Outdoor Unit Installation6. Refilling the refrigerant
Check the type of refrigerant to be used on the machine nameplate.Precautions when adding R410AFill from the gas pipe in liquid form.It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.1) Before filling, check whether the cylinder has a siphon attached or not. (It should have something like “liquid filling siphon
attached” displayed on it.)
• Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
NOTENational implementation of EU regulation on certain fluorinated greenhouse gases may require to provide the appropriate official national language on the unit. Therefore an additional multilingual fluorinated greenhouse gases label is supplied with the unit. Sticking instructions are illustrated on the backside of that label.
7. Refrigerant piping work7-1 Cautions on pipe handling
1) Protect the open end of the pipe against dust and moisture.2) All pipe bends should be as gentle as possible. Use a pipe bender
for bending.
7-2 Selection of copper and heat insulation materialsWhen using commercial copper pipes and fittings, observe the following:1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 0.045kcal/mh°C)Refrigerant gas pipe’s surface temperature reaches 110°C max.Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
3) Use separate thermal insulation for gas and liquid refrigerant pipes.• .
