ELECTRIC SHOCK HAZARD

To prevent injury or death due to electrical shock or contact with moving parts. Lock unit disconnect switch in open position before servicing unit.

Cooling and Heating Season

Basic Maintenance – For All Packaged Systems

To keep your unit operating safely and efficiently, a qualified service technician should check the entire system seasonally, and any other time that you feel a check is needed. Your service technician may examine these areas of the unit:

1.Filters (for possible cleaning)

2.Motors (condenser and evaporator motors are permanently lubricated)

3.Gaskets (for possible replacement)

4.Refrigerant coils (for possible cleaning)

5.Safety controls (for mechanical cleaning)

6.Electrical components and wiring (for possible replacement and connection tightness)

7.Condensate drain (for possible cleaning)

8.Inspect the unit duct connections to see that they are physically sound and sealed to the unit casing.

9.Inspect the unit mounting support to see that it is sound.

10. Inspect the unit to see that there is no obvious unit deterioration.

Heating Season Additional Maintenance – For Gas/Electric and Dual Fuel Packaged Systems

At the beginning of each heating season arrange for a qualified service technician to complete the unit inspections and service routines described in this section.

These steps should be performed ONLY by a qualified service technician.

1.Inspect the control panel wiring and heating controls to make sure connections are tight and wiring insulation is intact.

2.Check the operation of the gas ignition system.

a.Turn the unit on and off at the thermostat to be sure the ignition control and spark electrode are operating.

b.Turn off the gas supply with the unit operating to verify that the gas valve closes and that a re-ignition cycle is initiated by the ignition control.

3.Check the burner manifold pressure. A pressure tap is provided in the gas valve for this purpose.

HAZARDOUS GASSES

Exposure to fuel substances, or by-products of incomplete fuel combustion, is believed by the state of California to cause cancer, birth defects, or other reproductive harm.

This warning complies with State of California law, Proposition 65.

This product must be gas piped by a Licensed Plumber or Gas Fitter in the Commonwealth of Massachusetts.

4.Visually inspect all of the unit's flue product passageways for excessive deposit buildup or corrosion. If buildup or corrosion is apparent, perform the necessary repairs.

5.Visually check the main burner flames. They should be bright blue flames extending up to the heat exchanger sections.

ELECTRIC SHOCK HAZARD

Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the furnace before shutting off the electrical supply.

In the event that electrical, fuel or mechanical failures occur, the owner should immediately turn off the gas supply at the manual gas valve located in the burner compartment and electrical power to the furnace and contact service technician.

IMPORTANT: Some of these products have been designed and manufactured to meet ENERGY STAR criteria for energy efficiency. However, proper refrigerant charge and proper air flow are critical to achieve rated capacity and efficiency. Installation of this product should follow the manufacturer’s refrigerant charging and air flow instructions. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten equipment life.
