Carrier 58sta Stx

Can't find filter on my carrier 58STA / STX gas engine? 3

I have a business manual and I can't find the filter port listed there. I spent half an hour looking around with a flashlight and saw nothing. A diagonal tape whose size and airflow encryption has been dropped into a duct by the installer, but I can't find the filter holder either.

Depending on the outlet, the 58sta does not have an internal filter holder unless accessories are added later, page 37. Find the air return duct of the air return grill or ventilation unit.

Technicians have learned from day one that they should ask every customer to check their equipment once a year. However, I do not agree. Newer devices require less maintenance and should be sufficient every 3 years. Clean the igniter to check the fire sensor. Clean the burner. Clean the separator for the secondary heat exchanger. Other device failures cannot be predicted or avoided. Such as pressure switch that does not open or does not open at the end of its cycle, bad inductor circuit board that freezes the device, does not require thermostat, does not transmit heat, obstructs smoke, heat exchanger first Checked this temperature. The height is correct and the filter is in place. Fault Drain Valve If you are concerned about maintenance, avoid damage every 3 years. If the safety is higher than every year then your concern is safety. The new units are equipped with adequate safety equipment so that the engine is never endangered due to proper installation, proper amount of combustion air and internal pressure. .
May be behind the tape.
