Modesto/Modesto HotfillENGLISH en-3 2 Description This waterheater designed for storing and hea- ting drinking water. The waterheater contains an isolated innertank suitable for 10 litres of water. The in-built electrical heating element heats up the water. The waterheater can be incorporated into a water supply system by means of the hot-water and cold-water connection.

The main components are shown in figure 1 on page 1.

2.2 Product identification

The type plate contains the following data: - product name; - type number; - serial number; - capacity [L]; - quality marks; - working pressure [kPa or bars]; - power [W]; - electrical connecting value [V]; - CE marking; - damp resistance.

You will find the applicable quality marks on the type plate.

System under pressure (figure 2.1) Cold tap water enters the waterheater via the inlet combination. The thermostat and the elec- trical heating element heat up the water to the pre-set temperature. When the water is heated, it expands, increasing the pressure in the water- heater. This overpressure is limited by the relief valve of the inlet combination. Unpressurised system (figure 2.2) This application does not make use of an inlet combination. The special unpressurised mixing tap drains away the expansion water. During the heating of the water, the tap drips until the pre-set temperature has been reached. There should never be any obstruc- tion for the expansion water to drip from the tap. System under pressure (figure 2.3) The waterheater is included in the main hot water system. During use, the waterheater is filled directly with hot water from the main hot water provision, ensuring that it is always pos- sible to draw hot water. The thermostat and the electrical heating element heat up the water to the pre-set temperature. When the water is hea- ted, it expands, increasing the pressure in the waterheater. This overpressure is limited by the relief valve of the inlet combination. Figure 2.1 Basic operation of a pressurised system Figure 2.2 Basic operation of a unpressurised system

The temperature switch can be adjusted to continuously variable. - Minimum: Frostproof position (

). The water tempera- ture is approx. 10 °C; - 45 °C: Energy saving position. This position can be used for washing hands and rinsing, for instance. This position reduces calcifica- tion in the waterheater; - 60 °C: This is a common temperature for washing- up water; - 75 °C: Maximum position. For hot water or much warm water. The water heater supplies app. 20 litres of 40 °C. 3 Operation and use

3.2 Putting into operation and

terminating the system Check if the waterheater is filled with water! The waterheater is connected to the electricity grid by means of a wall socket.

• Connect the power plug to the wall socket to put the waterheater into operation;

• Disconnect the power plug from the wall socket to put the waterheater out of operation or turn the temperature adjustingknob to ”

(frost proof position).

3.3 Checking the operation

Systeem under pressure The waterheater heats up the water if the expan- sion water trickles from the relief valve. Unpressurised system The waterheater heats up the water if the expan- sion water trickles from the outlet pipe of the tap.

3.4 Activities regarding water main

If the water pressure should be cut off, for example due to activities regarding the main, flush - as soon as the water pressure is back - through a cold-water tap untill the water remains clear.

3.5 Water and energy saving

By using (hot) water with care, you protect the envi- ronment and decrease your water and energy bill. Fig. 3 Temperature adjusting knob with child-proofing

Modesto/Modesto Hotfill See also page 5 of this manual!en-4 ENGLISH 4 Maintenance Make sure that your waterheater is descaled once a year when you live in an area with hard water exceeding

dH (German standard of hardness)

Use a soft cloth with a non-aggressive clea- ning product to clean the outside of the waterheater.

4.2 Inlet combination

Regularly check whether the relief valve (Figure 2.1) is not obstructed in draining the expansion water from the waterheater. The outlet of the relief valve on the inlet combination must be kept open to the atmosphere. The relief valve on the inlet combi- nation must be regularly operated, to remove calcium deposits and to verify that it is not blocked. 7 End of useful live All materials used by Inventum are free of hazardous materials which could harm the environment when these are dismantled and/or destroyed. 6 Legionella prevention! The kitchen water heater is intended for use near to the kitchen tap which provide hot water for daily use. If the water temperature is higher than 45°C for any length of time and the water is used daily there is only a very limited risk of legionella. To avoid any risk after a long period of inactivity, it is recommended that the water should be heated once to a temperature higher than 60 °C and then allowed to flow through the tap for one minute . If the kitchen water heater is used for showers (for example in a caravan), or if hot water is not used for a long period regularly, it is recommended that the temperature be set higher than 60 °C. 5 Malfunctions This Inventum waterheater is extremely relia- ble. However, if any malfunctions should occur, follow the table of malfunctions (Table 1). Contact your fitter if malfunctions cannot be resolved by means of the actions prescribed! Please have the following information ready: - product name; - type number; - serial number. Do under no circumstance try to repair the waterheater yourself. A hazardous situation may occur, and besides your guarantee will lapse. The power supply cable may only be replaced by the Inventum Technical Service if it should be damaged, this to prevent dangerous situations.
