Frequently Asked Questions - DEE 1803 DIMPLEX

How to install the DEE 1803?

Installation must be carried out by a qualified installer. Mount the device firmly on the wall, first connect cold water (closed circuit) then the electrical supply (400 V three-phase with earth wire). Before first use, perform a purge by opening the hot water tap for at least 1 minute at a flow rate of 6 L/min.

What to do if the water is not hot enough?

Check that the household fuse has not blown. If the flow rate is too high, partially close the hot water tap. In winter, colder inlet temperature may require reducing the flow rate. If the problem persists, have the automatic cut-out checked by a technician.

Why is the water flow too low?

The strainer of the tap, shower head or heating block may be blocked. Clean or descale the strainer. If the strainer downstream of the non-return valve is obstructed, have it cleaned by a specialized technician.

The device does not start, what to do?

Ensure the electrical supply is restored (fuses). Perform a start-up purge: open the hot water tap for at least 1 minute at a flow rate of at least 6 L/min. If the flow is insufficient, remove the aerator or shower head and repeat the operation.

How to clean the device?

Wipe the device with a damp cloth. Never use abrasive or scouring detergent. For descaling, remove the strainer and clean or decalcify it if necessary.

What to do in case of frost or winter?

The device must be installed in a frost-free room. If the desired outlet temperature is not reached in winter, reduce the water flow at the tap until the desired temperature is obtained.

How to adjust the water temperature?

Use the temperature selector on the device for continuous adjustment. For economical use, set the temperature directly on the water heater rather than adding cold water. The recommended position for energy savings is 40 °C.

Why does cold water flow briefly?

This is normal when the device detects air in the water. The water heater briefly cuts the heating power and then restarts automatically after a few seconds.

How to save energy with this device?

Set the water temperature directly on the device to 40 °C (position R). Avoid adding cold water if the water is too hot: this wastes water and energy. A thermostatic mixer can also improve efficiency.

What to do after a water cut?

Turn off the device (disconnect the fuses). Open the hot water tap until the air is purged from the pipe. Reconnect the fuses. The device is then ready to operate.

Installation

Unpacking/Removing the cover

• Unpack the appliance and check for transport-related damage.
  Please dispose of the packaging, and if applicable, the old appliance in an environmentally-friendly manner.

Preparations for installation

Important: Only use the supplied installation set.

The supplied water connection nozzles must be installed!

• Shut off water supply. The electrical connection (connection cable) must be disconnected from the power supply. Unscrew the fuse or switch off the circuit breaker.

Electrical connection/Mounting

The electrical supply terminal can be fitted at the top or bottom. The sheath of the connection cable must extend for at least 40mm into the appliance.

Startup/additional information

First start-up

Switch on the fuses.
Setting the temperature.
- Starts rinsing: Open the warm water tap and allow water to flow for at least 1 minute (flow-rate at least 6 litres per minute). Only then (for safety reasons) will the appliance begin to heat.

Tip: Should the appliance not start because of a reduced flow-rate, remove the perlator, shower head or similar before start and repeat the process.

Remove the flow-rate limiter (see Fig. A) with low water pressure.
Explain the operation of the continuous-flow heater to the user.

If the continuous-flow heater does not have sufficient water flow due to low water line pressure in your domestic plumbing system, remove the flow-rate limiter.

Priority circuit for the combination with electrical storage heaters:

For operation with a priority circuit, a special load shedding relay BZ 45L20 (special accessory) is required. Other existing load shedding relays, with the exception of electronic load shedding relays, may malfunction.

The control electronics must be coded when operated with a load shedding relay.

Status display on the appliance

LED	Appliance status

Lights up	Ready
Slow flash (1/s)	Appliance is heating
Fast flash (4/s)	Desired water temperature is not reached (water flow too high for appliance rating).

The filter upstream from the check valve in the cold water supply inlet is clogged.

Remove the filter and either clean it or descale it. See Figure E 1-3.

Household-based applications include, e.g. usage in employees catering facilities for shops, offices, agricultural and other commercial operations, as well as usage by guests of guest houses, small hotels and similar residential establishments.

Risk of electric shock!

Switch off the mains voltage supply immediately if a fault occurs.

We do not accept liability for damage resulting from failure to heed these instructions.
The continuous-flow heater may only be connected and put into operation by a qualified professional.
Repairs may only be undertaken by a suitably qualified specialist to avoid potential sources of danger.
The continuous-flow heater may only be installed in a frost-free room.
- Persons (including children) with diminished bodily, sensory or mental perception, or those who lack knowledge or experience should not operate the appliance, unless they are monitored or have received instruction concerning use of the appliance by persons responsible for their safety.

Your new appliance

The electronically regulated flow-through heater warms the water while it flows through the unit.

How to operate the continuous-flow heater

The warm water temperature can be continuously adjusted on the electronically regulated flow-through heater:

Washbasin

Shower

With the use of a thermostat battery, the following settings are recommended for high temperatures or large quantities of water, for example:

Dish washing

Cleaning

Bath tub

Turn on the hot-water tap.

The continuous-flow heater switches on and heats the water when the hot-water tap is turned on.

It switches off again when the tap is turned off. Changing the supply water temperature correspondingly changes the outgoing water temperature.

Increasing the water temperature

If a higher temperature for a completely opened warm water tap is not achieved, more water flows than the flow-through heater can warm as a result its performance capabilities. In this case, the warm water tap must be closed somewhat.

Decreasing the water temperature

Startup after a water cutoff

• Switch off the appliance (unscrew the fuse in the house electrical installation).
  Turn on the hot-water tap until the air is purged from the pipe.
  Switch the fuse back on again.

The appliance is ready for operation.

Saving energy

Set the desired warm water temperature directly on the flow-through heater.

Mixing with cold water at the armature for water that is too hot consumes unnecessarily water and energy.

At approx. 40^ (temperature selection position ) the unit operates most economically.

Cleaning

Simply wipe the appliance with a damp cloth.

Do not use intensive or abrasive cleaning agents.

A fault, what to do?

If your appliance does not operate as required, it is often due to a very minor problem. Please check whether you can remedy the fault yourself by using the following guidelines. You will save yourself the costs of an unnecessary visit by customer service personnel.
