Children shouldbe supervised to ensure that they never play with theappliance.2.43.Test symbolsSee the type label on the appliance.4.General!DANGER: BurnsWater temperatures over 125 F (52 C) can causesevere burns instantly or death from scalding. A hotwater scalding potential exists if the thermostat on theappliance is set too high. Households with smallchildren, disabled or elderly persons may require thatthe thermostat be set at 113 F (45 C) or lower toprevent possible injury from hot water.The Tempra B and Tempra Plus units are designed to supply hotwater for a house, apartment or certain commercial applications.Unlike a conventional storage type water heater the Tempra tankless water heater does not store hot water. Instead, water is heatedinstantaneously as it flows through the unit. The Tempra offersgreater energy efficiency than storage type water heaters due tothe absence of stand-by losses and reduced hot water pipe runs.The input of heat into the water is controlled electronically. TheTempra will deliver any water temperature between 86 F (30 C)and 140 F (60 C). Please set the desired temperature using theknob on the front cover. The Tempra Plus Temperature adjustmentknob can be set to: OFF, 86.140 F (30.60 C).The Tempra B has a F and a C scale. The output temperature ofthe Tempra Plus is shown in the digital display in F or C units.( F or C units can be selected during installation, factory setting: F). The maximum temperature is electronically limited to 140 F(60 C).WWW.STIEBEL-ELTRON-USA.COMTEMPRA & TEMPRA PLUS 3ENGLISHIf you have any questions regarding the installation, use or operation of this water heater, or if you need any additional installationmanuals, please call our technical service line at (800)-582-8423.
OPERATIONGENERALFor reasons of appliance efficiency and durability (scaling), theoptimum temperature setting lies between 86 F (30 C) and120 F (50 C).The outlet temperature of the Tempra Plus can be limited (see"Initial settings").4.1General appearance4.2Tempra B units:In case the "Power” LED is flashing while the unit operates, thewater flow rate exceeds the heating capacity of the unit.

Crimp a ferrule over stranded bare wire to ensure a goodconnection.Consult the chart below for the recommended torque amounts onthe terminal block screws.Screw Diameter e (N cm) Torque (lbf 13.27-17.7Using the proper torque specifications to secure wire to the wiringblock helps to avoid personal loss or property damage.See 13, “Technical Data”, pg. 9 for information on the properwire gauge size.9.Initial settingsCheck whether the set value transducer cable is plugged into theslot TSoll A1 (Tempra B) or TSoll D (Tempra Plus) on the main PCB.2. Select a specific outlet temperature- Switch the appliance 'live'.- Open the casing so that coding plug Tmax / Tred becomesaccessible.- Set the temperature selector to "OFF". The coding plug mustbe set to Tmax (standard delivery).- Set coding plug to Tred; the setting mode will be activated andthe flashing display shows the current temperature limit.- Within the next 30 seconds, you can select the requiredtemperature (display continues to flash). The setting modewill terminate after 30 seconds; the programming unit willdisplay "OFF" again.10. Commissioning the water heater!WARNING: Open hot water faucet for a few minutesuntil water flow is continuous and all air is purgedfrom water pipes. The unit’s cover must be installedbefore the circuit breakers are turned on.1. Close the cover and fix it using the screw with the lockwasher.2. Turn on circuit breakers to bring electrical power to the unit.3. Turn the temperature selector clockwise and anti-clockwise,to calibrate the set value transducer.4. Adjust the water temperature to the desired level using theknob on the front cover of the unit.5. Turn on hot water and wait twenty seconds until temperaturehas stabilized.6. Check the water temperature with your hand and make surethat it does not feel too hot. Reduce if necessary.7. Explain to the user how the unit works and familiarize himor her with its use.Advise the user about possible hazards (hot water temperature up to 140 F / 60 C).

Normal maintenance!NOTICE: The Tempra does not contain any parts serviceable by the average user. In case of malfunctionplease contact a licensed plumber or electrician.Stiebel Eltron Tempra tankless water heaters are designed for avery long service life. Actual life expectancy will vary with waterquality and use. The unit itself does not require any regular maintenance. However, to ensure consistent water flow, it is recommended to periodically remove scale and dirt that may build upat the aerator of the faucet(s), the filter screen in the unit, or inthe shower head.WWW.STIEBEL-ELTRON-USA.COM
