Safety Summary

Electrical Precautions
Take the following precautions to reduce the risk of electric shock, fire or explosion resulting in serious injury or death:
· Only use electrical protection equipment and tools suited for this installation. · Insulate the wired controller against moisture and temperature extremes. · Use specified cables between units and the controller. · Communication cabling must be a minimum of 18-Gauge, 2-Conductor, Stranded Copper.
Shielded cable must be considered for applications and routing in areas of high EMI and other sources of potentially excessive electrical noise to reduce the potential for communication errors. When shielded cabling is applied, proper bonding and termination of the cable shield is required as per Johnson Controls-Hitachi Air Conditioning guidelines. Plenum and riser ratings for communication cables must be considered per application and local code requirements.
· The polarity of the input terminals is important, so be sure to match the polarity when using contacts that have polarity.
· Highly dangerous electrical voltages may be used in this system. Carefully refer to the wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death.
· Before installing the controller or remote devices, ensure that the indoor and outdoor unit operation has been stopped. Further, be sure to wait at least five minutes before turning off the main power switch to the indoor or outdoor units. Otherwise, water leakage or electrical breakdown may result.
· Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the main power supply. Before connecting or servicing the controller or cables to indoor or outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected. Verify with a meter and equipment.
· Use an exclusive power supply at the controller’s rated voltage. · Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit breaker, and
so forth) with the specified capacity. Ensure that the wiring terminals are tightened securely to recommended torque specifications.
· Clamp electrical wires securely with a cord clamp after all wiring is connected to the terminal block. In addition, run wires securely through the wiring access channel.
· When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular intervals, but not too tightly.
· Make sure that the terminals do not come into contact with the surface of the electrical box. If the terminals are too close to the surface, it may lead to failures at the terminal connection.
· Do not pour water on the controller as it could cause electric shock and/or damage the unit. Do not use strong detergent such as a solvent. Clean with a soft cloth.
· Check that the ground wire is securely connected. Do not connect ground wiring to gas piping, water piping, lighting conductor, or telephone ground wiring.

1. About FrostWash
· Regarding the noise upon freezing and defrosting
Cracking noise may be heard during the freezing or defrosting phase due to temperature change. Refrigerant flow noise may also be heard. The noise may be heard relatively louder in a quiet environment. It is recommended to set the “Auto-FrostWash Schedule” when the room is not occupied. Choose not to use the FrostWash function in places such as hotel rooms and hospitals, where consistent quietness is expected.
· Ice fog may come out from air outlet during the FrostWash operation. Ice fog could happen in a humid environment such as the room humidifier is used in a small room.
· FrostWash is available when the outside temperature is in the range of 34oF – 110oF (1oC – 43oC), and the indoor temperature is in the range of 59oF – 86oF (15oC – 30oC).
Also refer to technical documents of outdoor units because outdoor temperature range may vary depending on outdoor units’ type.
· The temperature around the indoor unit may drop slightly during FrostWash operation.

2. Start FrostWash
