CHECKLIST FOR THE INSTALLER



A Quick Check List

Are the water connections to the water heater oriented in a way to avoid



trapping air in the heating circuit? (see diagram on next page)

Is the purge valve installed on the return water line from the air handler



upstream from the isolation valve?

Is the air handler hung and isolated to avoid transmitting vibration through



framing and duct work?

Are the isolation valves full-port? Restrictive valves will limit performance.



Is outdoor cooling unit contactor wired according to the wiring diagram?



Are Thermostat connections correct, including cooling and continuous run



connections? Do they operate their intended zone?

Have the packing materials been removed from the blower?



Is there an installation manual and controls user manual for the home owner ?



Is the unit accessible? Are there clearances for service and component



replacement?

Is the return duct/drop acoustically lined ? (recommend lining at least 6 ft. of



the return duct/drop)

Is the filter cover in place? Is a clean filter in place?



Has the electronic controller been properly configured as per instructions in the


