Electrical instant water heaters are recommended for continuous supply of hot water in cottages and country houses, stand-alone cafeterias and restaurants, and office rooms, as well as they can be used as standby equipment in apartments for the preventive maintenance period of the hot water supply network.

The main advantage of instant water heaters is their capability to supply unlimited quantity of hot water, when you just open the tap. Water is heated immediately, when it flows through the heating element with high heat output. Electrical energy is only consumed upon hot water use, which excludes loss of electrical energy related to heat accumulation. In addition, there is no need for regular service care of instant water heaters.

Rainforest electrical instant water heaters by Hyundai are free-flow and designed for heating of tap water in household use, for operation in an open water supply circuit only, and for a single consumption point. Water is heated, when it flows through a heat-resistant plastic heating flask with a copper heating element. The dry run protection is provided by a diaphragm-type pressure sensor, which energizes the heating element upon water feed. When water flowing through the heating flask is overheated, a temperature limiter de-energizes the heating element with the restart capability.

* For connection to the electrical mains, this series of water heaters is complete with a power cord and a male plug. The power cord has length of 1.5 m and copper conductor section of 3x1.5 mm2.

Never use an electrical male plug and socket for connection of the water heater to the electrical mains, except for H-IWR1-3P series. The water heater shall be connected to the 220 VAC power supply source permanently with obligatory connection to the electrical grounding loop. Make sure that resistance of the grounding loop is < 4 Ω. The electrical cable is led into the water heater through its rear wall and connected to the terminal block according to marks on the rear panel, where        - ground conductor, L - phase conductor, N - neutral conductor. To lead in and connect the electrical cable, remove the appliance front panel. For that, unscrew the securing screw in its upper part. After connection of the electrical cable to the terminal block, make sure that all clamping screws of the terminal block are secured. Secure the cable inside the heater using a clamping plate, place back the front panel, and turn in the securing screw in the upper part of the appliance.


* The service life of the power indicator is 3000 hours continuously. Therefore, disconnect the appliance from the electrical mains after use to extend the power indicator life.

Incoming water is heated inside the heating flask, when it flows through the heating element. Water temperature in the water supply network may fluctuate throughout the year from +3°C to +20°C. Therefore, water flow in winter shall be made lower than in summer to obtain the optimum water temperature. Water flow is controlled by the valve at the water inlet of the water heater. Never install an isolation valve or shut off water flow at the water heater outlet. After activation of heating, wait for 10-20 sec until temperature of heated water is stabilized.

For adjustment of hot water temperature, use the valve at the inlet connection (cold water inlet). When you decrease inlet flow rate of water, you increase outlet temperature of water and vice versa. For water heaters of H-IWR1-5P and H-IWR1-6P series, you can also place the On/Off/power control knob to the low power position (      ) or to the medium power position (      ) in or-der to adjust water temperature. To switch off the water heater, place the On/Off/power control knob to the OFF position (      ), close the cold water feed valve at the inlet, and de-energize the water heater.


Operation of the water heater may result in scaling of the shower/tap nozzle openings. This reduces efficiency of heating, deteriorates water spraying, and increases water pressure in the heating flask.

For prevention of such phenomena, periodically clean the nozzle using household chemical agents and soft brushes. Do not use abrasive cleaning substances and inappropriate chemical agents.

Prior to cleaning the outer surfaces, disconnect the water heater from the electrical mains and allow it to fully cool down. Clean the outer surface of the appliance housing with a slightly moist-ened soft cloth and then wipe it dry. Do not use abrasive cleansers for cleaning.

If water flow rate from the water heater decreases, clean the coarse filter (rubber gasket and strainer) installed at the cold water inlet of the water heater. For that, disconnect the appliance from the electrical mains and allow it to fully cool down. Then, shut off cold water feeding, unscrew the cold water supply pipe from the water heater, remove the rubber gasket with the strainer, and flush it under a jet of flowing water. Restore the inlet connection in the reverse sequence.

1 - Off position2 - On/Off and power control knob3 - Low power position4 - Medium power position5 - Full power position

Before first start or after a long idle period of the water heater, fill it with water opening the cold water feed isolation valve and make sure that cold water steadily flows from the water outlet at the consumption point. After that, switch on the appliance and make sure that the power indica-tor on the front panel lights up*.

To switch on heating, place the control knob to the ON position (      ). If sufficient water flow and pressure at least 0.08 MPa are available, the water heater will start heating water.

Upon expiration of service life, the water heater shall be disposed. For more details regarding disposal of the water heater, please contact a representative of the local authorities.

Service life is around 10 years. The notion of the service life of the device is not equal to the warranty period.



                                           Refer to «Water heater safe operation and installation rules».

During installation of the water heater, rigorously observe the laws, regulations, directives, and standards (safety requirements, disposal rules/procedure, electrical safety rules, etc.) effective in your country, as well as directives of local electrical energy/water suppliers.


During selection of a location for the water heater, it is necessary to ensure free access to it on the basis of not less than 0.3 m from above, from below, and sideways. This will ensure the maximum comfort for maintenance and adjustment of the water heater, when necessary. After you have selected the place for installation of the water heater, mark points for mounting screw holes. Drill two holes to appropriate depth in the wall using a drill with suitable size for the dowel pins and screws provided in the water heater package. Insert the dowel pins into the wall holes and turn in the mounting screws. Do not turn in the screws fully. There shall be a gap between the screw heads and wall necessary to hang up and secure the water heater. Hang up the water heater onto the screws and check security of mounting. The appliance shall be installed on the wall strictly horizontally with its connections downward. For more secure mounting, you can use the through hole in the lower part of the rear panel (refer to “Overall and installation dimen-sions”) to turn in an additional screw through it to the wall.

Water supply network connection

The water heater is directly connected to the cold water supply network with operating pressure from 0.07 MPa to 0.6 MPa. If water pressure in the water supply network exceeds 0.6 MPa, install a reduction valve (pressure reducer) in the feed system so that operating pressure does not exceed 0.6 MPa. Prior to connecting the water heater, flush the cold water supply pipe with flowing water.

If water hardness in the water supply main exceeds 450 mg/l (CaCO3), we recommend you to use a separate water filter upstream of the water heater inlet to extend service life of the heating element.

Connect the cold water supply pipe to the cold water inlet marked with blue color. Install the rubber gasket and strainer provided in the package between the pipe and connection. The con
