Installation Manual 

For distribution to dealers and contractors

All electric work must be performed by qualified personnel.

Do not install the unit in a place where large amounts of oil, steam, 
organic solvents, or corrosive gases, such as sulfuric gas, are present 
or where acidic/alkaline solutions or sprays are used frequently. These 
substances can compromise the performance of the unit or cause 
certain components of the unit to corrode, which can result in electric 
shock, malfunctions, smoke, or fire.

To reduce the risk of shorting, current leakage, electric shock, 
malfunctions, smoke, or fire, do not wash the controller with water 
or any other liquid.

To reduce the risk of electric shock, malfunctions, smoke or fire, do 
not operate the switches/buttons or touch other electrical parts with 
wet hands.

To reduce the risk of injury or electric shock, before spraying a 
chemical around the controller, stop the operation and cover the 
controller.

To reduce the risk of injury or electric shock, stop the operation and 
switch off the power supply before cleaning, maintaining, or inspecting 
the controller.

Properly install all required covers to keep moisture and dust out of the 
controller. Dust accumulation and water can cause electric shock, 
smoke, or fire.

To reduce the risk of injury, keep children away while installing, 
inspecting, or repairing the controller.

To reduce the risk of fire or explosion, do not place flammable 
materials or use flammable sprays around the controller.

To reduce the risk of damage to the controller, do not directly spray 
insecticide or other flammable sprays on the controller.

To reduce the risk of electric shock or malfunctions, do not touch 
the touch panel, switches, or buttons with a pointy or sharp object.

To reduce the risk of injury and electric shock, avoid contact with 
sharp edges of certain parts.

To avoid injury from broken glass, do not apply excessive force on the 
glass parts.

To reduce the risk of injury, wear protective gear when working on the
controller.
