TRONIC ES2.5, ES4, ES8
Point-of-Use Electric Mini-Tank Water Heaters
Engineering Specifications
Water heater shall be a Model TRONIC ES2.5, ES4 or, ES8
Installation shall consist of ___Model TRONIC ES2.5 electric minitank water heaters as distributed by Bosch Thermotechnology Corp. and 98% thermal efficiency. Supply voltage shall be 110 - 120VAC with a heating capacity of 1440 Watts.
Installation shall consist of ___Model TRONIC ES4 electric minitank water heaters as distributed by Bosch Thermotechnology Corp. and 98% thermal efficiency. Supply voltage shall be 110 - 120VAC with a heating capacity of 1440 Watts.
Installation shall consist of ___Model TRONIC ES8 electric minitank water heaters as distributed by Bosch Thermotechnology Corp. and 98% thermal efficiency. Supply voltage shall be 110 - 120VAC with a heating capacity of 1440 Watts.
The electric mini-tank water heaters shall be UL listed for the US and Canada and UPC certified.
CONSTRUCTION
Water heater shall be electrically powered with compact minitank design for point-of-use operation and an efficiency rating of 98%. Tank shall be glass-lined and insulated for thermal retention. Unit shall be protected by a tough plastic housing. Tank shall be rated for maximum working pressure not less than 150 psig. Water heater shall be equipped with a pressure relief valve and a magnesium anode rod for protection against tank
corrosion. Water connections for inlet and outlet shall be ½” NPT male for ES2.5 and ES4. Water connections for inlet and outlet shall be ¾” NPT male for ES8.
The controls shall be a wired thermostat with temperature selector and a high temperature safety cut-out. A red light shall indicate when the unit is powering the heating element.
INSTALLATION
All aspects of installation of electric mini-tank water heater shall be in strict accordance with manufacturer’s instructions. Materials shall conform to all manufacturer’s recommendations including electrical connections and wiring.
Water heater piping shall be field constructed of materials as specified. Water heater shall be installed with water shutoff valves for service and maintenance.
MODE OF OPERATION
The heater shall include integral factory wired thermostat to control all operation and energy input. Control of outlet water temperature shall be set through an internal set point with
a field adjustment of 65 to 145 degrees F. Heater shall be capable of maintaining the temperature set point +/- 3 degrees F by supplying power to the 1440 Watt heating element.
WARRANTY
The inner tank shall carry a 8 year warranty. All other parts and components shall carry a 1 year warranty against defects in materials or workmanship.
