Questions and answers

What people ask about this product, answered by our pool techs.

What is the difference between EC-462028 and 460736?
Both are Pentair's MasterTemp 400 for natural gas. Pentair keeps part numbers that begin with EC- for online sale and sells 460736 through dealers. This listing is EC-462028.
What warranty does Pentair give the MasterTemp 400, EC-462028?
One year, parts only. That is Pentair's warranty for its e-commerce (EC) models and for online purchases. The two years printed in Pentair's brochures is its standard warranty, which does not cover a heater bought online.
Where is the manual for the Pentair MasterTemp 400?
Under Downloads on this page, as the Owners Manual. It is Pentair's MasterTemp Installation and User's Guide, part number 472592, which covers the 175,000 to 400,000 BTU models in natural gas and propane, the HD and ASME versions included.
What does the SERVICE HEATER light mean on a MasterTemp 400?
On older MasterTemp heaters with indicator lights, SERVICE SYSTEM means not enough water is reaching the heater and SERVICE HEATER means a fault in the heater or its controls, with a row of lights marked AGS, AFS, HLS, PS, THERMISTOR and SFS to show which. Heaters built now show an ERR code on the display instead. Both are explained in our pool heater error code guide.
Is EC-462028 the natural gas or the propane MasterTemp 400?
Natural gas. Pentair builds each MasterTemp 400 for one fuel, and the propane version is a separate part number.
Can the MasterTemp 400 be installed indoors?
It ships set up for outdoor installation, with its venting built in. Pentair sells a vent conversion kit for indoor installations in the US and Canada, and recommends a carbon monoxide detector near any heater installed indoors.
