Features and safety devices

Easy to operate and environmentally friendly

The heat pump has user interface with easy use menu keys for ease of programming. The heat pump is also environmental friendly as it transfers heat from the surrounding area into the water.

Heating capacity

The unit absorbs ambient energy and releases the heat into the water stored in the tank. If the ambient temperature is low, the heating capacity of the heat pump will be reduced, but you can still rely on the electric element for backup.

Thermal Cut Out (TCOs)

The water heater is equipped with one thermal cut out (TCO) located above the heating element, in contact with the tank surface. If for any reason the water temperature becomes excessively high, the thermal cut-out (TCO) cuts the power circuit to the heating element. Once activated, the TCO must be reset manually. Resetting of the temperature limiting control should be done by a qualified service technician.

CAUTION:

The cause of the high temperature condition must be investigated by a qualified service technician and corrective action must be taken before placing the water heater in service again.

System theory

The refrigerant circuit is a closed system in which the refrigerant R134a circulates as a heat transfer medium.

The evaporator transfers the heat from the air to the refrigerant circuit, and the refrigerant evaporates into a gas.

The compressor compresses the refrigerant R134a, thus increasing its temperature.

Then the heat is transferred via a heat exchanger, also referred to as a condenser, to the storage water tank. The refrigerant

R134a condenses in the process.

R134a flows through the expansion valve in a liquid state with decreasing pressure. Then it is routed back to the evaporator.

Brief overview of modes

• Heat pump mode: only the economical heat pump cycle is used; if the air temperature goes beyond the nominal range (3 °C - 40 °C) the appliance automatically turns off.

• Combi mode: the heat pump cycle is used under the nominal range for the air temperature (3 °C - 40 °C); if the air temperature goes out of this interval, the appliance automatically switches to the electrical heating element; this is the factory pre-selected mode.

4.4.2 Dielectric joint (not supplied with the appliance)

Different metals between plumbing and tank materials and additionally the effect of hot water can cause the corrosion of one of the metals (generally the one in the tank is the metal attacked).

The Dielectric Joint will basically avoid any physical contact between the two metals, acting as an effective insulator and prevent this attack. How quickly this, or if at all, this happens depends a lot on the content of your water; its pH, the dissolved minerals and the metals involved.

BOSCH therefore advises the use of the dielectric joint, that is to be installed between the house piping and the tank water connections.

4.4.3 Condensate Drain Tubes (not supplied with the appliance)

This unit has an integrated condensation tray. The water collected in the tray drains out of the tube coming off the back of the unit. It is important that a hose is attached to the drain port off the back of the unit.

▶ Attach one end of the condensate drain pipe(15mm inner diameter recommended) to the drain port on the back of the unit.

▶ Direct the other end to a drain in the floor or no higher than

8 cm above the ground in an outdoor installation.

If such drain is unavailable, a condensate drain pump (not provided) must be purchased and installed.

Installation instructions | 17 valve and the tank. Please observe local codes for the correct installation of relief valves.

WARNING:

The pressure rating of the relief valve must not exceed 1000 kPa, the maximum working pressure of the water heater as marked on the rating plate.

WARNING:

Relief valve easing gear should be operated

AT LEAST ONCE EVERY SIX MONTHS. If water does not discharge freely when the lever is operated, the valve should be checked by an authorized agent.

WARNING:

The relief valve and relief valve drain pipe must not be sealed or blocked. Small amounts of water may leak from relief valve during heating cycles.

WARNING:

Relief valves should be checked every six months, or replaced at intervals not exceeding 3 years or more frequently in areas where there is a high incidence of water deposits.

6720801244-10.1V

Fig. 10

4.4.4 TPR Valve (supplied with the appliance)

A temperature and pressure-relief valve is supplied and must be installed in the tank port marked for this purpose. No valve or accessory of any type should be installed between the relief

WARNING:

The function of the temperature and pressure relief valve once installed on this water heater is to discharge high temperature water under certain conditions. Therefore it is strongly recommended that the pipe work connected to the relief valve is able to withstand water temperatures exceeding 99 °C. Failure to follow this recommendation may result in a dangerous situation.

The kW rating of the relief valve must not be less than the input rating of the water heater as indicated on the rating label located on the front of the heater.

Compress 3000 DW FO 6 720 801 244 (2013/08)

18 | Installation instructions

WARNING:

Never block or seal the outlet of the PTR valve or it's drain for any reason.

The warranty will be void if the relief valve or other safety devices are tampered with or if the installation is not in accordance with this manual.

Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact any electrical parts, persons or animals and to eliminate any other possible risks.

A drain line from a relief valve must comply with the requirements of AS/NZS 3500.4.

WARNING:

To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment required by local codes and no 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 of AS/NZS 3500.4, AS/NZS

3000 and all local codes and regulatory authority requirements.

Always use a valve of the same rated pressure and temperature as the PTR Valve supplied with the unit.

4.4.5 Thermal expansion tank (not supplied with the appliance)

Thermal expansion is a natural process where heated water increases its volume. When this water is stored in a tank, this volume increase will in fact mean a pressure increase. This pressure increase can result in a dangerous situation. If the safety settings on the relief valve are reached, then the relief valve will operate during the heating cycle. Thermal expansion, if normally reaching the relief valve nominal values, can cause premature valve failure and contribute to increased components stress.

Bosch recommends therefore the installation of an expansion tank in order to relieve this over-pressure, avoiding repeated relief valve operation.

Please contact a licensed professional, water supplier or plumbing inspector for more information about this subject.

4.4.6 Temperature mixing device (not supplied with the appliance)

WARNING:

This water heater can heat water to temperatures which can cause scalding.

Bosch recommends the installation of a temperature limiting device between the water heater and the hot water outlets in a bathroom or similar usage point, in order to reduce the risk of scalding.

Additionally, a certified plumber may have the legal obligation to ensure the water heater installation meets the hot water delivery requirements listed in AS/NZS 3500.4.

4.4.7 Pressure limiting valve (not supplied with the appliance)

In installations where the mains water supply temperature

exceeds that specified for this product (listed in chapter 3), an

approved pressure limiting valve is required and must be fitted.

If the water heater is supplied with low pressure water, below the minimum working pressure specified for this product

(listed in chapter 3), then a pressure pump should be installed

in order to minimize the forming of air traps in the hydraulic circuit.

4.4.8 Expansion control valve (not supplied with the appliance)

Local regulations, a saturation index greater than +0.4 or in corrosive water areas where there are sufficient quantities of silica dissolved in the water may require the installation of an expansion control valve (ECV) in the cold water line, being the last valve installed prior to the water heater.

4.5

If the ambient temperature is outside of the range 3 °C-40 °C, the pump will not be able to run by using the heat pump mode. The electric element will be used if COMBI mode is selected (default mode) and until the ambient air temperature returns to the operating range. If HEAT PUMP mode is selected the electric element will not be used outside the nominal operating range to heat up the water.

4.11 Off-peak compatibility

The appliance is technically compatible to be connected to a fix line for off-peak tariff. However, the off-peak must be wisely used.

Off-peak periods off less than 16 hours might not ensure the reheating, depending on the hot water demand and on the temperature of the air and inlet water. Ensure that your offpeak periods are suitable for your needs.

The weekly LEG mode requires additionally 6 to 7 hours.

Therefore once a week this additional period must be ensured to complete the thermal disinfection. It is recommended to programme the LEG to be done when extended off-peak periods are available, typically weekends.

To optimize the comfort and maximize the savings, it is recommended the use of a power commutator between the normal line and the off peak line together with a programmed working period (

section 5.6.2). The best strategy will

depend up on the hot water needs and ambient conditions.

In case time of use tariffs are available, it is recommended to use the programmed working periods (

section 5.6.2) to

take full advantage of them.

In case of a temporary suspension on the water supply during a off-peak period the appliance may get unpurged and stop working during its restart. An error message will be displayed and the appliance will remain blocked. To minimize the possible inconveniences from a suppression on the water supply service, always check the appliance after such incident occurred.

NOTICE: Damage to the appliance!

Never use the off-peak in case the appliance is set to OFF mode and temperatures around

0 °C or below are expected: the anti-freeze mechanism will not be ensure!

6 Maintenance and repair

WARNING:

The water heater should be serviced by a qualified professional and in accordance with the Plumbing Standard AS/NZS

3500.4 and local authority requirements.

WARNING:

Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.

It is part of normal operation for the

Temperature and Pressure Relief valve to discharge periodically. This is due to thermal expansion in a closed water system. If this discharge becomes excessive and runs continuously, contact plumbing contractor.

Do not plug the relief valve outlet.

Properly maintained, your water heater will provide years of dependable trouble-free, economic service.

It is suggested that a routine preventive maintenance program be established and followed by the user.

6.1

Periodic Inspection

It is recommended that a periodic inspection of the operating controls, heating elements and wiring should be made by service personnel qualified in electric appliance repair.

Most electrical appliances, even when new, make some sound when in operation. If the hissing or singing sound level increases excessively, the electric heating element may require cleaning. Contact a qualified installer or service agent.

Additionally it is also recommended that the evaporator and refrigeration circuit are checked every two years for dust and residues. In dusty environments it may be necessary to have the appliance checked and cleaned on a more regular basis.

6.2

Temperature and pressure relief valve (PTR

Valve)

At least every 6 months.

▶ Lift and release the lever handle on the temperature and pressure-relief valve, to make certain the valve operates freely.

Allow several liters to flush through the discharge line to an open drain.

Never replace the PTR Valve with one which has a higher pressure rating than is specified for your water heater.

If the valve does not discharge water when the release lever is opened or does not seal properly when release lever is closed, replacement by an authorised person must be arranged without delay.

The PTR Valve is not serviceable.

DANGER:

Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.

6.3

Flushing tank

A water heater’s tank can act as a settling basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank.

It is advisable to periodically flush the tank of these deposits by

draining and then refilling the unit (see section 6.4).

6.4

Draining the Water Heater

CAUTION:

Shut off power to the water heater before draining water.

CAUTION: Risk of scalding!

Check the appliance's DHW temperature before opening the safety valve.

▶ Wait until the water temperature has dropped enough to prevent burns and other damage.

Compress 3000 DW FO 6 720 801 244 (2013/08)

36 | Maintenance and repair

Large volumes of water will drain from the cold water inlet (>270 liters).

▶ Ensure proper drainage of water.

▶ Close cold water supply.

▶ Open a hot water tap (preferable one install at the same level as the appliance) to relieve pressure and wait until flow substantially decreases.

▶ After ensuring a proper drainage solution, remove cold water inlet connection and wait until water is drained.

6.5

Vacation and Extended Shutdown

If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent the buildup of dangerous hydrogen gas.

The water heater and piping should be drained if they might be subjected to freezing temperatures. After a long shutdown period, the water heater’s operation and controls should be checked by qualified service personnel. Make certain the water heater is completely filled again before placing it in operation.

Note: refer to the Hydrogen Gas Caution in the Operating Instructions.

Inspecting the anode rod is therefore very important.

Sacrificial anodes are designed to deteriorate overtime. Most water heating industry professionals recommend inspecting the anode yearly.

Homes with salty or softened water supplies should consider more frequent inspection. When in doubt consult a local water heating professional.

▶ Arrange for an authorised person to inspect the anode and replace if required.

6.9

Checking/replacing the magnesium anode

The appliance is protected against corrosion by an internal magnesium anode.

WARNING: Damage to the appliance!

The magnesium anode must be installed before commissioning the appliance.

6.6

Clearing the Condensation Drain Tubes

The condensate drain is located on the back of the water heater. If blocked, water will spill down the outside of the unit.

▶ Remove the condensate drain pipe.

▶ Clear any debris and reattach.

▶ Periodically inspect the drain line and clear any debris that may have collected in the line.

▶ See Installation Instructions for more information.

6.7

Refrigerant circuit

NOTICE: Refrigerant leak!

▶ Repairs to the refrigerant circuit (e.g. to the compressor, condenser, evaporator, expansion vessel) may only be carried out by an authorised contractor.

WARNING: Damage to the appliance!

Appliances operated without this protection are excluded from our warranty.

▶ Check the magnesium anode yearly and replace if required.

The internal wall of the DHW storage tank is coated with a double glass lining. The coating is designed for normal quality

water (section 4.8.1, page 21). When using more corrosive

water, the warranty only applies if additional safety measures

(i.e. dielectric joints) have been taken, and the magnesium anode is checked more frequently.

To check the protective anode:

▶ Isolate the appliance from the power supply.

▶ Isolate appliance from water supply.

▶ Open a hot water tap (preferable one install at the same level as the appliance) to relieve pressure and wait until flow substantially decreases.

▶ Remove the anode rod protective cap.

6.8

Anode Rod servicing

A water heater anode rod is the most important safeguard any storage tank has against corrosion and premature failure.
