Important Environmental Concerns!
Scientific research has shown that certain
In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs).
Not all refrigerants containing these compounds have the same potential impact to the environment.
The manufacturer advocates the responsible handling of all
WARNING Hazardous Voltage with Capacitators!
Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.
Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.
Overview of Manual
Note: One copy of this document ships with each unit and is customer property. It must be retained by the customer.
This booklet describes proper installation, operation, and maintenance procedures for PTACs. By carefully reviewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be minimized.
It is important that periodic maintenance be performed to help assure trouble free operation. A maintenance schedule is provided at the end of this manual. Should equipment failure occur, contact a service organization with qualified, experienced HVAC technicians to properly diagnose and repair this equipment.
Responsible Refrigerant Practices!
The manufacturer believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry.
All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, recovering, recycling and reclaiming of certain refrigerants and the equipment that is used in these service procedures.
In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors may result in equipment damage.
