START-UP AND OPERATION

Step 1 —Checking Air Purifier Operation

!WARNING

ELECTRICAL SHOCK AND HIGH VOLTAGE HAZARD

Failure to follow this warning could result in personal injury or death.

Before installing or servicing system, always turn off main power to system. There may be more than one (1) disconnect switch.

a.Attach the Infinityt Air Purifier door to the cabinet. A magnet in the door (see Fig. 8) is used to activate a safety switch in the power supply when the door is installed. The power supply will not energize the air purifier unless the safety switch is activated.

b.Turn the HVAC system power on and adjust the thermo- stat or Infinityt System Control to activate the system fan.

c.Turn the Infinityt Air Purifier power switch to on posi- tion.

d.The power indicator light above the Air Purifier power switch should illuminate (see Fig. 13).

e.Check to ensure the light goes off when the Infinityt Air Purifier power switch is set to off, when the blower goes off, or when the HVAC system power is turned off.

NOTE: Upon power-up, the light will come on for approximately 5 seconds and if no flow is detected, it will go off. If no air purifier cartridge is detected, the flow sensor will detect this and turn off after approximately 7 seconds.

Step 2 —Infinity Control

a.When the Infinityt Air Purifier is used with an Infinity Control, the Infinity Control can be configured to remind the homeowner when it is time to change the Infinityt Air Purifier cartridge. This maintenance reminder can be based on either the TrueSenset dirty filter algorithm or time. The installer should use their discretion to select the most appropriate option based on the initial system static pressure.

Step 3 —Maximizing Performance

a.Maximum air purification performance is obtained when the furnace blower is set for continuous operation on the thermostat or Infinity Control.

Frequency of air purifier cartridge replacement and cleaning of the ionization array may vary depending on ductwork design and local environmental conditions.

To replace the air purifier cartridge, complete the following steps:

Step 1 —Turn the heating and cooling system power off.
