Refrigerant Precautions
To reduce the risk of serious injury or death, the following refrigerant
precautions must be followed.
Ɣ As originally manufactured, this unit contains refrigerant installed by Johnson Controls. Johnson
Controls uses only refrigerants that have been approved for use in the unit’s intended home country
or market. Johnson Controls distributors similarly are only authorized to provide refrigerants that
have been approved for use in the countries or markets they serve. The refrigerant used in this unit is

unit must comply with the country’s requirements with regard to refrigerant use and should be obtained
from Johnson Controls distributors. Use of any non-approved refrigerant substitutes will void the
warranty and will increase the potential risk of injury or death.
Ɣ If installed in a small room, take measures to prevent the refrigerant from exceeding the maximum
allowable concentration in the event that refrigerant gases should escape. Refrigerant gases can cause
asphyxiation (0.026 lbs/ft
3
(0.42 kg/m
3
) based on ISO 5149 for R410A). Consult with your distributor for
countermeasures (ventilation system and so on). If refrigerant gas has leaked during the installation
work, ventilate the room immediately.
Ɣ Before installation is complete, make sure that the refrigerant leak test has been performed. If

Ɣ When installing the unit, and connecting refrigerant piping, keep all piping runs as short as possible,
and make sure to securely connect the refrigerant piping before the compressor starts operating. If
the refrigerant piping is not connected and the compressor activates with the stop valve opened, the
refrigerant cycle will become subjected to extremely high pressure, which can cause an explosion or

Ɣ Highly dangerous electrical voltages are 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.
Ɣ Before servicing, open and tag all disconnect switches. Never assume electrical power is disconnected.
Check with meter and equipment.

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 cable is applied, proper bonding and termination of the cable shield is required as per Johnson
Controls guidelines. Plenum and riser ratings for communication cables must be considered per
application and local code requirements.

Ɣ Clamp electrical wires securely with a cable clamp after all wiring is connected to the terminal block. In
addition, run wires securely through the wiring access channel.
Ɣ When installing the power lines, do not apply tension to the cables. Secure the suspended cables at
regular intervals, but not too tightly.
Ɣ 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.

Otherwise, water leakage or electrical breakdown may result. Disconnect the power supply completely
before attempting any maintenance for electrical parts. Check to ensure that no residual voltage is
present after disconnecting the power supply.
Ɣ Do not clean with, or pour water into, 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.
Ɣ Check that the ground wiring is securely connected. Do not connect ground wiring to gas piping, water
piping, lighting conductor, or telephone ground wiring.
Ɣ If a circuit breaker or fuse is frequently activated, shut down the system and contact your service
contractor.

3. Before Operation
Power is turned on. Apply power to the outdoor unit(s) at least 12 hours prior to operation of the
system for preheating of the compressor oil. Make sure that the outdoor unit is not covered with
snow or ice. If it is, remove it by using hot water that is approximately 122
o
F (50
o
C).
If the water temperature is higher than 122
o
F (50
o
C), it will cause damage to plastic parts.
