Abstract
A thermostat control for an electric water heater is held in firm contact with the heater storage tank by a mounting assembly comprising a tank bracket including a body having an opening adapted to lockingly fit over the heater tank stud and a pair of laterally-spaced legs extending from the body and having a bent upper end portion adapted to apply spring pressure toward the tank outer wall. The mounting assembly also includes a thermostat bracket carrying the thermostat control and having a pair of laterally-spaced, upstanding ears adapted to fit beneath the upper end portion of the legs on the tank bracket. Each of the ears includes a nib which is received in a slot in the legs on the tank bracket to interlock the two brackets. The nib has an upper edge which engages the upper end of the slot and urges the thermostat control into firmer contact with the outer wall of the heater tank in response to upward vertical movement of the thermostat bracket relative to the tank bracket, such as when an installer pulls on the pigtail leads connected to the thermostat control during connection with supply wiring.
