General information

Thank you for choosing an Elwa instant water heater.

To ensure your own safety and that of others you need to read these installation and operating
instructions before using the unit for the first time.

Please keep the instructions and other documentation close to the unit for future reference
Failure to observe this instruction may lead to damage to the instantaneous water heater.

This product should not be disposed with other household waste. To prevent possible harm to the
environment or human health from uncontrolled waste disposal, recycle it responsibly to promote the
sustainable reuse of material resources.

Plumbing installation work, commissioning and maintenance of this appliance should only be undertaken by a
licensed plumber and comply with the AS 3500:4 for plumbing and drainage.

Electrical connections must be made by a licensed electrician according to AS3000 for electrical installations

This water heater must be connected to a reliable earth connection at all times.
The electrical resistance of the water should not be less than 1300 Ω/cm².

Your water supplier/company can inform you about the electrical resistance (specific resistance) of the water
in your area. The water heater should not be installed in an area exposed to the risk of freezing.

Do not operate a Hotrun in a “dry state”, the electrical power should remain switched off until the Hotrun is

completely filled with water. If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.

This water heater is manufactured in accordance with applicable standards and has been tested by the
relevant authorities. It has been certified to comply with CE declaration of electromagnetic conformity. The
technical specifications of the unit are shown on the label of the water heater

This appliance is not intended to be programmed by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible for their safety.

Mounting instructions

The ELWA Hotrun electric instantaneous water heaters are designed for both point of use (most
efficient and lowest water and energy consumption) and multipoint applications, such as hand
wash basin/shower/kitchen sink(s), in fact all places where instant hot water is required.

The heating of the water is started instantly by opening a tap or valve connected to the hot water
outlet.

The outlet water temperature depends on the following factors:

- The flow rate through the HOTRUN (can be controlled by a flow restrictor on the cold water inlet side)
or the incoming flow into the Hotrun can be restricted by a flow regulating ball-valve.

- How far the hot water tap is actually opened

- The temperature of incoming cold water

- The mixing of hot- and cold water

When closing the hot water tap or when the flow drops below a minimum flow rate the heating
will be stopped automatically. The performance of the Hotrun depends on its electrical capacity
(kWatt rating) and also depends on the Voltage of the power supply.

A temperature rise of 25°C can be expected with the following (variable) flow rates:

The cold inlet water temperature effects the performance of the water heater, the higher the inlet water
temperature, the more flow can be expected from the Hotrun water heater.
A pressure of 90kPa is the minimum required for correct operation.

The screws and plugs are supplied with the unit.

1. Mark the position of the plugs or screws according to the positional template.

2. Mount the unit using 2 screws for the straight bracket.

3. Fit the top screws allowing it to protrude approximately 2-3 mm. Slide the bracket onto the

protruding screws and ensure that it is secured without movement.

4. Fit the last securing screw between the hot- and cold water connection.
