The home is only 1500 ft.² and the unit is a 5 ton. The unit experiencing extremely high static pressure SA.43 RA.56. The unit is producing a very high temperature split. I checked the settings and found the unit was set to a 4 ton with standard blower tap speeds.. I changed the blower speed to the lower settings and checked static pressure. The static pressure are in more acceptable range RA.35 SA.26 The unit is now producing a 23° split. The condensation line was an indoor style and the sun had melted it. I replaced the condensation P-trap to the proper dimensions for a Bosch unit. The unit is operating properly at this time.
