Warning:
Carefully read the labels attached to the unit.
Warning:
•The unit must not be installed by the user. Ask an installer or an authorized technician to install the unit. If the unit is installed improperly, water leakage, electric shock, or fire may be caused.
•The unit must be installed according to the instructions in order to minimize the risk of damages by earthquakes, typhoons, or strong winds. An improperly installed unit may fall down and cause damages or injuries.
•The unit must be securely installed on a structure that can sustain its weight. If the unit is mounted on an unstable structure, it may fall down and cause damages or injuries.
•If the air to water heat pump is installed in an enclosed area, measures must be taken to prevent the refrigerant concentration in the room in the event of refrigerant leakage. Consult an installer regarding the appropriate measures. Should the refrigerant leak and cause the concentration oxygen in the room may lack.
•All electric work must be performed by a qualified technician according to local regulations and the instructions given in this manual. The units must be powered by dedicated power lines and the correct voltage and circuit breakers must be used. Power lines with insufficient capacity or incorrect electrical work may result in electric shock or fire.
•Use only specified cables for wiring. The wiring connections must be made securely with no tension applied on the terminal connections. Also, never splice the cables for wiring (unless otherwise indicated in this document). Failure to observe these instructions may result in overheating or a fire.
•Terminal block cover panel of the outdoor unit must be firmly fixed. If the cover panel is mounted improperly, dust and moisture may enter the unit, and it may cause electric shock or fire.
•When installing or moving the air to water heat pump, make sure to use the specified refrigerant (R410A) to charge the refrigerant lines. Do not either mix it with any other refrigerant or allow air to remain within the pipes. Air enclosed in the pipes can cause pressure peaks resulting in a rupture and other hazards.
•Make sure to use accessories authorized by Mitsubishi Electric and ask an installer or an authorized technician to install them. If accessories are improperly installed, it may cause water leakage, electric shock, or fire.
•Do not remodel the unit. Consult an installer for repairs. If alterations or repairs are not performed correctly, it may cause water leakage, electric shock, or fire.
•The user should never attempt to repair the unit or transfer it to another location. If the unit is installed improperly, it may cause water leakage, electric shock, or fire. If the air to water heat pump needs to be repaired or moved, ask an installer or an authorized technician.
•After installation has been completed, make sure that refrigerant does not leak. If refrigerant leaks into the room and comes into contact with the flame of a heater or portable cooking range, poisonous gases will be released.
•Use clean enough water which meets water quality standards. The deterioration of water quality may result in the system breakdown or the water leakage.
•Never use anything other than water as a medium. It may cause a fire or an explosion.
•Do not directly use heated or cooled water that is produced by the air to water heat pump as drinking and cooking water, or swimming pool. There is a risk to damage your health. There is also a risk that installing the water heat exchanger may corrode if the necessary water quality for the air to water heat pump system cannot be maintained. If you wish to use the heated or cooled water from the heat pump for these purposes, take measure such as to isolate the second heat exchanger within the water piping system.
•When installing or relocating, or servicing the air conditioner, use only the specified refrigerant (R410A) to charge the refrigerant lines. Do not mix it with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high pressure in the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specified for the system will cause mechanical failure or system malfunction or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.
1.1. Before installation
Caution:
•Do not use the unit in an unusual environment. If the air to water heat pump is installed exposed to steam, volatile oil (including machine oil), or sulfuric gas, or exposed to briny air, or covered with snow, the performance can be significantly reduced and the internal parts can be damaged.
•Do not install the unit where combustible gases may leak, be produced, flow, or accumulate. If combustible gas accumulates around the unit, it may cause fire or explosion.
•The outdoor unit produces condensate during the heating operation. Make sure to provide drainage around the outdoor unit if such condensate is likely to cause damage.
•When installing the unit in a hospital or in a building where communication equipment is installed, you may need to take measures to reduce noise and electronic interference. Inverters, home appliances, high-frequency medical equipment, and radio communications equipment can cause the air to water heat pump to malfunction or to breakdown. At the same time, the noise and electronic interference from the air to water heat pump unit may disturb the proper operation of medical equipment, and communications equipment.

1. Safety precautions
1.2. Before installation (relocation)
Caution:
•Be fully careful when moving the units. The unit must be carried by at least 2 people, as it weighs 20 kg or more. Do not hold the packaging bands. Wear protective gloves to unpack and to move or install it, in order to avoid your hands being injured by fins or the edge of other parts.
•Be sure to safely dispose of the packaging materials. Packaging materials, such as nails and other metal or wooden parts may cause injuries.
•The base of the outdoor unit must be periodically checked to ensure it is not loose, cracked or damaged. If such defects are left untreated, the unit may fall down and cause damage or injuries.
•Do not wash the air to water heat pump unit. You may receive an electric shock.
1.3. Before electric work
Caution:
•Be sure to install a circuit breaker. If it is not installed, there may be a risk of an electric shock.
•For the power lines, use standard cables of sufficient capacity. Otherwise, it may cause a short circuit, overheating, or fire.
•When installing the power lines, do not apply tension to the cables. The cables may be cut or overheated resulting in a fire.
•Make sure to ground the unit. Do not connect the ground wire to gas or water pipes, lightning rods, or telephone grounding lines. If the unit is not properly grounded, there may be a risk to get an electric shock.
•Make sure to use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and molded case circuit breaker) with the specified capacity. If the circuit breaker capacity is larger than the specified capacity, breakdown or fire may result.
1.4. Before starting the test run
Caution:
•Turn on the main power switch more than 12 hours before starting operation. Starting operation immediately after turning on the power switch can severely damage the internal parts. Keep the main power switch turned on during the operating period.
•Before starting operation, check that all panels, guards and other protective parts are correctly installed. Make sure not to get injured by touching rotating, hot, or high voltage parts.
•Do not touch any switch with wet hands. There may be a risk of an electric shock.
•Do not touch the refrigerant pipes with bare hands while unit is running. The refrigerant pipes can be hot or cold depending on the condition of the flowing refrigerant. There may be a risk to get burn or frostbite.
•After stopping operation, make sure to wait at least five minutes before turning off the main power. Otherwise, it may cause water leakage or breakdown.
1.5. Using R410A refrigerant air to water heat pump
Caution:
•Use only R410A refrigerant. If another refrigerant is used, the chlorine will let the oil deteriorate.
