Frequently Asked Questions - Modesto Hotfill INVENTUM

How to set the temperature of my Modesto Hotfill water heater?

Turn the temperature adjustment knob continuously. The antifreeze position (star) gives about 10 °C, the economy position (45 °C) is recommended for hand washing, 60 °C for dishes and 75 °C for boiling water. You can lock the knob with the child safety by positioning the red device with a screwdriver.

What to do if the water is too cold?

First check the thermostat setting: if it is too low, increase it. Also check the child safety which may limit the temperature. If the water heater has operated without water, the safety thermostat may have tripped: remove the knob and press the Reset button (J). Make sure the hot water pipe is well insulated.

What to do if the water is too hot?

Turn the temperature adjustment knob to a lower position. If the problem persists, the thermostat may be defective; contact your installer.

How to use the child safety?

Place the temperature knob on the star position (antifreeze). With a screwdriver, slide the red device to the desired maximum temperature (45 °C, 60 °C or 75 °C). The knob will then not be able to exceed this value.

How to maintain my water heater?

Clean the exterior with a soft cloth and a non-abrasive product. Have the unit descaled annually if the water is hard (over 12 °dH). Regularly operate the discharge valve of the safety group to prevent limescale deposits.

What to do in case of a leak?

If the discharge valve leaks constantly, the mains pressure may be too high: install a pressure reducer. Activate the valve several times to loosen it. If the leak comes from the water heater itself, cut off the power supply, close the shut-off valve and contact your installer.

How to drain the water heater?

Unplug the unit and close the main tap. Open a hot water tap to reduce pressure. Disconnect the connection hoses, then place the water heater horizontally with the cold water connection at the bottom to completely empty it.

What is the warranty of this water heater?

The warranty is 5 years on the inner copper tank and 2 years on other parts, from the date of purchase. The purchase invoice is required. The warranty does not cover damage due to incorrect use or excessive scaling.

How to prevent legionellosis?

Use hot water daily. Set the temperature to at least 60 °C after a prolonged period of inactivity, then let the hot water run for one minute. For regular use, a temperature of 45-60 °C is sufficient in the kitchen.

What to do if the water heater makes boiling sounds?

This is usually due to significant limescale build-up. Contact your installer for a descaling of the unit. Do not attempt to repair yourself, as you risk voiding the warranty.

2.4 Basic operation

Modesto

System under pressure (figure 2.1)

Cold tap water enters the waterheater via the inlet combination. The thermostat and the electrical 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 obstruction for the expansion water to drip from the tap.

Modesto Hotfill

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 possible to draw hot water. The thermostat and the electrical heating element heat up the water to the pre-set temperature. When the water is heated, it expands, increasing the pressure in the waterheater. This overpressure is limited by the relief valve of the inlet combination.

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^ 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^ 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^ .

Storage temperature	Legionella growth water use	Daily hot	Advice
< 25 °C	No growth	not necessary	Setting only for frost protection
25 - 40 °C	Growth is possible	required	Setting not advised
45 - 60 °C	Growth not possible	required	Only for kitchen use
> 60 °C	Legionella dies	not necessary	Always safe

Legionella risk at set water heater temperatures

WARNING!

For waterheaters set at high temperature there is a burning hazard (more specifically for children).
