Electricalworkshouldbeperformedbyqualiedelectricalengineersinaccordancewith“EngineeringStandardsForElectrical
Installation” and the supplied installation manuals. Special circuits should also be used. If the power circuit lacks capacity or has an
installationfailure,itmaycauseariskofelectricshockorre.
1. Follow ordinances of your government organization for technical standard related to electrical equipment, wiring regulations, and guidances of each electrical power company.
2. Power should be taken from the special branch circuit.
3. Install a ground breaker to the power.
4. Install the unit so that the control circuit cables (remote controller, transmission cables, or external input/output line) is not in direct contact with the power cable outside the unit.
5. Ensure that there is no slack on all wire connections.
6. Vermin may have access to and damage the power, remote controller, and transmission cables. To prevent damage, insert cables into metal piping.
7. Do not connect the power cables to the transmission cable leads.
8. Connect control cables to the indoor unit, remote controller, and the outdoor unit.
9. Ground the unit.
10. Select control cables following instructions.
Caution:
Be sure to put the unit to the ground on the outdoor unit side. Do not connect the ground cable to any gas pipe, water pipe, lightening rod, or telephone cable. Improper grounding may cause electric shock.

11-3-1. Installation
Selecting an installation site
• Do not install outdoors. The unit is not waterproof.
• Back up system is recommended in case of PWFY unit breakdown.
• The unit will get hot. Do not install in a location where heat gets trapped inside.
• Be sure to install unit in a place strong enough to withstand its weight.
Any lack of strength may cause unit to fall down, resulting in a personal injury.
• Do not install the unit where corrosive gas is generated.
• Have installation work in order to protect against earthquake.
Any installation deciency may cause unit to fall down, resulting in a personal injury.
• Pay a special attention to the place, such as a basement, etc. where refrigeration gas can stay, since refrigeration is
heavier than the air.
• Do not install the unit where combustible gas may leak.
- If the gas leaks and accumulates around the unit, an explosion may result.
• When installing the unit in a hospital, communication station, or similar place, provide sufcient protection against
noise.
- The inverter equipment, private power generator, high-frequency medical equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. Also, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.
• Do not install the unit on a structure that may cause leakage.
- When the room humidity exceeds 80 % or when the drain pipe is clogged, condensation may drip from the indoor unit. Perform collective drainage work together with the unit, as required.
Securing installation and service space
•Please secure the following service spaces after installation.
(All servicing can be performed from the front of the unit) [Fig. 4]

11-3-6. Water Processing and Water Quality Control
11. SYSTEM DESIGN
To preserve water quality, use closed water loops for the unit. When the circulating water quality is poor, the water heat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion of the heat exchanger. Please pay careful attention to water processing and water quality control when installing the water circulation system.
• Removeofforeignobjectsorimpuritieswithinthepipes.
During installation, take extreme care that foreign objects such as welding fragments, sealant particles, or rust, do not enter
the pipes.
• WaterQualityProcessing
a) Depending on the quality of the cold-temperature water used in the air-conditioner, the copper piping of the heat
exchanger may become corroded. We recommend regular water quality processing.
Cold water circulation systems using open heat storage tanks are particularly prone to corrosion.
When using an open-type heat storage tank, install a water-to-water heat exchanger, and use a closed-loop circuit on the air conditioner side. If a water supply tank is installed, keep contact with air to a minimum, and keep the level of dissolved oxygen in the water no higher than 1mg/liter.
b) Water quality standard
Reference : Guideline of Water Quality for Refrigeration and Air Conditioning Equipment. (JRA GL02E-1994)
c) Please consult with a water quality control specialist about water quality control methods and water quality calculations
before using anti-corrosive solutions for water quality management.
d) Whenreplacingapreviouslyinstalledairconditioningdevice(evenwhenonlytheheatexchangerisbeingreplaced),rst
conduct a water quality analysis and check for possible corrosion.
Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion. Ifthewaterqualitylevelhasdropped,pleaseadjustwaterqualitysufcientlybeforereplacingtheunit.
Do not exceed the maximum of 100L circulating water in the water pipe.
