Pentair MasterTemp Heater Master Service Package, Water and Electrical Parts | 461100

The Pentair Master Service Package puts the common replacement parts for a MasterTemp or Max-E-Therm high-performance heater into one reusable hard case. It covers both the water and electrical systems. The water side includes two thermistors, a water pressure switch, two high-limit switches, a manifold bypass valve kit and a thermal regulator kit with its spring, o-ring, cap and spring clip. The electrical side adds an ignition control module, a control board kit (NA, LP series), a 115/230V transformer, an air flow switch, a stack flue sensor, two automatic gas shutoff (AGS) switches and an igniter and igniter gasket kit. Three 1.25 amp fireman's switch fuses, two Buna o-rings and a membrane pad round out the case.

The kit fits Pentair MasterTemp and Sta-Rite Max-E-Therm high-performance heaters, models 175, 200, 250, 300, 333 and 400. It is not compatible with the 125,000 BTU heater. Individual parts can be reordered to refill the case. Pentair also offers electrical-only and water-only versions as part numbers 461101 and 461102.
