▶ READ ALL INSTRUCTIONS BEFORE USING THIS WATER HEATER.
▶ This water heater must be grounded. Connect only to properly grounded outlet. See “GROUNDING INSTRUCTIONS” found on “INSTALLATION INSTRUCTIONS” .
▶ Install or locate this water heater onlyin accordance with the provided installation instructions.
▶ Use this water heater only for its intended use as described in this manual.
▶ The models ES2.5 and ES4 come equipped with a power cord. Do not use an extension cord. If no outlet is available adjacent to the water heater, contact a qualified electrician to have one properly installed near the heater. The model ES8 must be hard-wired. See installation instructions.
▶ As with any appliance, close supervision is necessary when used by children.
▶ The water heater must be supplied with water that meets the standards provided in section 3.1 – Water Chemistry Requirements.
▶ When a supplemental source of hot water is supplied to this Tronic 3000T, provisions must be made to ensure that the temperature of the heat source does not exceed the thermostat setting on this Tronic 3000T.
▶ If the water heater has been retrofitted with supplemental heating equipment, you must adjust both the thermostat that controls the supplemental heat source (located in the piping) and the thermostat on the Tronic 3000T (located behind the front panel) to the same temperature. Failure to adjust both thermostats to the same temperature can cause loss of correct temperature control.
▶ Do not operate this water heater if it is has a damaged cord or plug, if it is not working properly, or if it has been damaged or dropped.
▶ This water heater should be serviced only by qualified service personnel. Contact a service person for examination, repair or adjustment.
▶ Failure to replace the anode rod at least once every two years may cause the tank to fail and leak. We also recommend inspecting the anode rod annually and replacing it immediately if it is corroded or pitted. Damage caused by not maintaining the anode rod is not covered under the manufacturer’s warranty.
▶ Any water heater should be installed in such a manner that if it should leak, the resulting flow of water will not cause damage to the area in which it is installed. National Plumbing codes require a drain pan for any water heater installation. Failure to install one is the sole responsibility of owner and/or installer. Reference UPC 2006 (Uniform Plumbing Code) Section 508.1, or IPC 2006 (International Plumbing Code) Section 504.7.
NOTICE:
▶ The installer should review the contents of this manual with the owner upon completion of installation, and the manual should be left with the owner and placed in a location close to the installation.
NOTICE:
▶ The manufacturer is not responsible for the damages caused by improper installation or by failure to follow instructions in this manual. Comply with the installation instructions before completing electric connection.
NOTICE:
▶ The thermostat has been pre-set at the factory at a temperature equal or below 51.7 °C (125 °F). DANGER:
▶ Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally 2 weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen gas is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at the time it is open.
CAUTION:
▶ Any water heater should be installed in such a manner that if it should leak, the resulting flow of water will not cause damage to the area in which it is installed. National Plumbing codes require a drain pan for any water heater installation. Failure to install one is the sole responsibility of owner and/or installer. Reference UPC 2006 (Uniform Plumbing Code) Section 508.1, or IPC 2006 (International Plumbing Code) Section 504.7.
NOTICE:
▶ Prior to connecting the power supply, ensure tank is full of water and system is purged of air. Failure to do so may result in dry-fire damage to the appliance, which is not covered under warranty.
NOTICE:
▶ Tank failure due to neglecting to maintain the anode rod is not covered under warranty (see Section 5 Maintenance).

Installation instructions

The ES2.5 and ES4 water heaters are designed to be installed under the sink.
3.1 Water Chemistry Requirements
The chemistry of the water supplied to the water heater may affect efficiency, and may cause damage or premature failure to the appliance and associated equipment. Water chemistry must be analysed by a professional to determine if it is necessary to treat the water, and if treatment is required the professional should provide advice on a suitable solutions. It is the responsibility of the installer to ensure that the appliance is supplied with water that is potable 1) , free of corrosive chemicals, sand, dirt, and other contaminants, and is within the parameters shown in the Water Chemistry Requirements Table below. In addition, operating temperatures above 135°F will accelerate the natural accumulation of lime scale and potentially shorten the life of the appliance.
Failure of the appliance due to lime scale build-up, and/or being supplied with water that is outside of the required chemistry parameters, is NOT covered by the warranty.
3.2 Water Chemistry Requirements Table

| Values
---|---
Ph| 6.5 to 8.5
Hardness| 4 to 20 Grains/US Gallon
Chloride Concentration| ≤ 100 ppm
Total Dissolved Solids| ≤ 500 ppm
Conductivity (mS/cm| ≤ 1200

Table 3
1) Potable water is defined as drinkable water supplied from utility or well water in compliance with EPA secondary maximum contaminant levels (40 CFR Part 143.3). lf the water contains contaminants higher than outlined by the EPA, water treatment is recommended and more frequent maintenance may be required. If you suspect that your water is contaminated in any way, discontinue use of the appliance and contact a licensed professional for assistance.
3.3 Mounting the heater
3.3.1 Wall mounting
NOTICE:
The ES2.5 and ES4 water heaters come equipped with a power cord.
▶ Ensure the circuit breaker supplying the electrical outlet for the water heater is properly sized to handle the load of both the water heater and another appliance (e.g. dishwasher). See Table 2 for water heater electrical specifications.
▶ Fasten the supplied mounting bracket to the wall.
NOTICE:
Material damages!
▶ Use screws that are suitable for the wall material and the weight of the heater when filled with water.
▶ Hang the water heater on the bracket.
▶ Tug down wards on the heater to ensure that both “fingers” of the bracket are seated in the mounting slots.
3.3.2 Floor mounting
▶ Heater can sit on floor.
3.4 Pipe connections
▶ Connect the cold water inlet pipe to the inlet tapping (marked with a blue ring).
▶ Ensure a isolation valve is installed on the cold water supply to the water heater.
▶ Connect the hot water outlet pipe to the outlet tapping (marked with a red ring).
The model ES8 can be piped horizontally from the side or vertically from the top.
Horizontal installation – ES8 Model Only
If you wish to install the unit horizontally, with the piping connections on the right side:
▶ Install supplied brass plug into tap between hot and cold water connections.
▶ The supplied Temperature and Pressure Relief Valve will need to be installed on top. See location of T&P relief valve in ** Fig. 7.
Vertical installation
If you wish to install the unit vertically, with the piping connections on top:
▶ Install supplied brass plug into tap on side of water heater.
▶ The supplied Temperature and Pressure Relief Valve will need to be installed on top. See location of T&P relief valve in **Fig. 5 and **Fig. 6.
Caution
CAUTION:
To reduce the risk of excessive pressures and temperatures in this water heater:
▶ Install the supplied temperature and pressure protective equipment required by local codes but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems, ANSIZ21.22.
The supplied temperature and pressure relief valve is marked with a maximum set pressure (150 psi) that does not exceed the marked maximum working pressure of the water heater.
▶ Install the valve in the opening provided and marked for this purpose in the water heater.
▶ Orient it or provide tubing so that any discharge from the valve will exit within 6 inches above, or at any distance below, the structural floor, and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances.
National Plumbing codes may require a drain pan for the water heater installation. Failure to install one is the sole responsibility of owner and/ or installer. Reference UPC
(Uniform Plumbing Code), or IPC (International Plumbing Code).
3.5 Closed system thermal expansion
Periodic discharge of the temperature and pressure relief valve or failure of the element gasket may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a checkvalve, backflow preventer or water pressure reducing valve which will create a closed water system.
During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. The temperature and pressure relief valve may discharge hot water under these conditions which results in a loss of energy and a build-up of lime on the relief valve seat.
To prevent this from happening, there are two recommendations:
1. Install a diaphragm-type expansion tank that is suitable for potable water on the cold water supply line. A minimum 0.5 gallon expansion tank should be used.
Contact the local water supplier or plumbing inspector for information on how to control this situation. Do not plug the temperature and pressure relief valve.
3.6 Electrical connections**
The ES8 model must be hard wired. As per the National Electric Code the ES8 needs to be wired with 12 GA. wire to a 20 amp branch circuit.
Do not use surge protectors or multi-outlet adapters with this water heater.
▶ Unscrew the junction box cover and remove it.
▶ Insert 12 AWG through conduit into junction box and secure with conduit strain relief (not supplied).
▶ Connect the wires and screw on the cover of the junction box.
▶ Make appropriate wiring connections to the water heater per the National Electric Code.
The unit must be grounded with supplied grounding cable inside junction box.
▶ Secure junction box cover once wiring connections have been made.
When the ES8 is not within sight of the electrical circuit breakers, a circuit breaker lockout or additional local means of disconnection for all non grounded conductors must be provided that is within sight of the appliance. [REF NEC 422.31].

9. Nº4 screws for junction box fixing
10. Junction box
11. Housing for junction box (in the plastic front cover)

Use

4.1 Starting and testing
NOTICE:
DO NOT supply power to water heater until filled with water. If the water heater is powered on prior to being filled with water, it could lead to dry- fire damage. This is not covered under warranty.
To fill the heater:
▶ Open supply valve for water heater to fill with water.
▶ Open hot water tap(s) supplied by the water heater to purge air out of the system. Once air is purged, close hot water tap.
▶ Visually check for any leaks.
Turning heater on
For models which are not fitted with a switch:
▶ Supply power to the water heater by plugging in the power cord (models ES2.5, ES4) or turning on the circuit breaker (model ES8). If the light does not come on, turn the control knob in a clockwise direction.
The light will come on until water temperature has reached the thermostat temperature setting. The light will come back on any time the water temperature inside the tank drops below the thermostat setting.
4.2 Temperature setting
The temperature of the hot water is adjusted by rotating the knob M located on the front cover. Temperature range is 65 – 145 °F.
▶ Turn the knob clockwise to increase temperature.
▶ Turn the knob counter-clockwise to decrease temperature.

Maintenance

CAUTION:
Do not attempt to repair this water heater yourself. Call a service person for assistance. Always turn off the power supply to the heater prior to servicing or draining the heater.
Required maintenance
For all of the following operations, the power must be removed from the water heater (ES2.5 and ES4; Unplug from the wall power outlet. ES8; Turn off the circuit breaker at the mains panel). For some of the following operations the water must be drained from the water heater too.
5.1 Removing the cover
▶ Pry off the round cover plate [V] from its right hand edge [W] with a small flat-head screwdriver.
▶ Remove the Phillips screw revealed beneath the round cover plate.
▶ The cover [C] can now be removed by pulling out its left- hand edge. When reassembling, work in the opposite way being careful to insert the tongue of the cover into the slot.
5.2 Draining the heater

If the heater has been installed with rigid piping:
▶ Siphon the water out through any (lower) service valve on the (inlet side).
▶ Keep a hot water faucet open while siphoning the water out.
5.3 Inspecting the anode rod
The purpose of the anode rod ( **Fig. 13, [N]) is to protect the tank against corrosion. It is critical that the anode rod be inspected once a year to determine whether it requires replacement (and it must be replaced at least once every two years). To access the anode rod, the heating element must be removed (see Section 5.4 Removing the heating element). Upon inspection, the anode rod surface should appear smooth. If the rod surface appears pitted, bumpy, rusty, or if the rod is missing completely, then it must be replaced before the water heater can be put back into operation.
To access the anode rod:
▶ Remove the heating element (see Section 5.4 Removing the heating element).
Original anode rod sizes**

• ES2.5, ES4: length 5⅛”, diameter ⅝”
• ES8:length 6½”, diameter ¾”

Certain installations may require more frequent replacement of the anode rod:

• recirculation applications;
• poor water quality;
• galvanic/electrolytic corrosion
• high flow applications

In the event of poor water quality, Bosch recommends consulting a local water treatment professional for water treatment options. Always ensure the water heater is grounded. Models ES2.5 and ES4 must be connected only to a properly grounded outlet.  Damage resulting from poor water quality or failure to replace the anode rod is not covered under the manufacturer’s warranty. For additional questions, please call Bosch Technical Service.
5.4 Removing the heating element
▶ Turn off power supply and drain the heater (see previous section).
▶ Remove the front cover plate, disconnect terminals X, Y and T.
▶ Unscrew the 4 heating element retaining nuts F.
▶ Remove thermostat temperature sensor from well [B] located on the element assembly.

Video instructions on how to remove the heating element and check the anode rod can be found online here: https://youtu.be/5Ne5lan9Cis or by scanning this QR code.https://scnv.io/HCIy?qr=1
5.5 Descaling the heating element
Scale deposits can affect the heating capability of the element. Heavy scale can even cause damage to the element. The element can be descaled either chemically or manually:
▶ Soak the element in white vinegar or other descaling solution.
▶ Once descaled, rinse well with fresh water, to which you should add some baking soda,
-or
▶ Once the element has dried, use a soft brush (non metallic to prevent damaging the stainless steel sheath) on element.
▶ Brush the dried mineral off.
▶ Reinstall the element with gasket and make the wire connections. NOTICE:
Make sure the tank has been refilled with water before restoring power.

Replacement of parts

6.1 Changing the anode rod
▶ Turn off the power supply and drain the heater (see Draining the Heater).
▶ Remove heating element (see previous section).
▶ Unscrew anode rod from threaded connection.
▶ Remove and replace the anode rod ( **Fig. 13 [N]).
▶ Reinstall heating element.
▶ Refill tank with water before restoring power.
6.2 Changing the heating element
▶ Turn off power supply and drain the heater (see Draining the Heater).
▶ Remove the heating element (see section on Removing the Heating Element)
▶ Install new element with gasket, making sure the gasket and element are positioned correctly. Tighten the retaining nuts and make the wire connections.
▶ Ensure that the thermostat temperature sensor is inserted into the well located on the element assembly and secured with black rubber grommet.
▶ Refill tank with water before restoring power.
6.3 Changing the thermostat**
▶ Turn off power supply.
▶ Disconnect the 2 wire connectors on thermostat.
▶ Loosen the two brass screws at right side of thermostat and pull wires out.
▶ Remove thermostat temperature sensor from well located in element assembly.
▶ Unscrew and remove the two Phillips screws holding the thermostat onto the tank.
▶ Install new thermostat and re-attach wiring and screws.
▶ Ensure that the thermostat temperature sensor is inserted into the well located on the element assembly and secured with black rubber grommet.

Troubleshooting

If light does not come on, check that the high limit reset button is pushed in; follow steps in section 7.1.
If the indicator light works properly but temperature does not get hot at the tap, test for a plumbing crossover; shut off cold supply to heater and open hot water tap. There should be no water flowing. Any continued flow indicates a crossover which will effect the temperature and will need to be corrected. Also, it’s important to understand that this is a storage tank water heater and so it will take time for the water to get up to the set temperature. If the appliance has only recently been filled with water and the power turned on, please allow approximately 20 minutes to come up to temperature.
Call a qualified service technician to test the resistance of the heating element (8-10 ohms). Heating element should be replaced if readings are outside these values.
Light not on.| If the light does not come on, but water gets hot, check for faulty bulb.
Check high limit reset button; follow steps in section 7.1;
Brown water.| Brown or rusty water indicates a “spent” anode rod and possible deterioration of the tank body. Inspect the tank for leaks.
Check anode rod (see section on changing the anode rod).
Odor in water.| Smelly water could be due to an unusual reaction between local water and the heater’s anode rod. Check anode rod (see section 6.1 Changing the anode rod).
Failure to do so may result in damage to the tank and leaks.
Leaking| Check water fittings and T & P fitting on top of tank.
Remove front cover and inspect heating element gasket.
If tank is leaking call Bosch Water Heating for warranty claim if still within warranty period.
Check anode rod (see section 6.1 Changing the anode rod).

7.1 Resetting High Limit Switch
Occasionally, the high temperature limit shut off device may trip the reset. This occurs when water temperature exceeds 190 °F. The shut off device may also trigger from a power outage or electrical storm.
To reach the thermostat:
▶ Disconnect power cord (or shut off circuit breaker – model ES8) and remove the front cover.
▶ Firmly press reset button [B] with the tip of a ball point pen or similar object.A click indicates the reset was tripped.
▶ Reconnect power.
IMPORTANT: Check the operation of the thermostat:
▶ Turn temperature dial from high to low.
If the red light does not go off on low setting:
▶ Turn off power supply and call a service person to replace the thermostat.
If the red light does go off the thermostat is working well:
▶ Place dial setting to desired setting.
A lower setting is more economical, reduces the risk of scalding, and may also help to slow down the natural accumulation of lime scale inside the water heater.
▶ Replace cover plate.
CAUTION:
Call a technician if the high limit needs to be reset frequently. Frequent activation of the high limit may indicate that lime scale has formed on the heating element.
▶ Please refer to section 5.5 Descaling the Heating Element for further details.
