Safety Warnings
WARNING: Equipment used for heating, air conditioning and water heating can cause injury if
safety precautions are not observed. These systems generally use a 230 volt power supply which is
double the voltage used by other household appliances. Electrical shock from these systems could
cause personal injury or death. Before performing any service or maintenance operations on a sys-
tem, turn off main power switches to the unit, and turn off the auxiliary heater power also if used.
Although your geothermal unit has been designed and manufactured with your safety in mind, and is certified to the
safety standards of ETL, failure to observe safety precautions can result in injury. Only trained and qualified service
personnel should install, repair, service or adjust heating and air conditioning equipment. Untrained personnel can
perform the basic maintenance functions listed below. All other operations should be performed by trained service
personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and
labels attached to the unit and any other safety precautions that may apply.
Do not allow children or pets to play around the unit.

When performing the following functions, adhere to these safety precau-
tions:
Replacing a disposable filter — Turn off the unit and fan at the
thermostat.
Cleaning an electrostatic filter — Turn off the unit and fan at the

Checking or cleaning the internal condensate drain pan — Turn off

edges of the air coil. Wear safety glasses and work gloves. Do not
allow water to drip onto electrical components in the unit.
Cleaning or replacing media for unit-mounted or duct-mounted
humidifiers — Turn off all power supplies to the unit and humidifier.
Cleaning thermostats — Do not spray cleaning solution directly
