Intended use

NARVI infrared heaters are exclusively intended for wall mounting in infrared and sauna cabins.
Infrared heaters may only be used for heating infrared and sauna cabins.
Although the heaters have an installed safety temperature limiter, only infrared or sauna control units that comply with standard EN 60335-1 and EN 60335-2-53 may be used for operation.
Any use other than the described use of the infrared heater is considered improper use. This may lead to product damage, serious injuries, or death.

Safety instructions for the installer

Only an electrician or similarly qualified person may carry out the installation.
Work on the infrared heater may only be carried out when it is disconnected from the power supply.
The instructions provided by the cabin manufacturer must also be followed when installing the infrared heater.
Compliance with the safety distances to flammable objects must be ensured.
The enclosed plugs must be used. However, if the infrared heater is connected without plugs, an all-pole disconnecting device with full shut-down in line with overvoltage category III must be used.
Also, note the instructions provided by the infrared or sauna control unit manufacturer. In particular, the maximum connected power ratings of the control unit must not be exceeded.
A “Do not cover” warning must be attached to or near the infrared heater.
The infrared heater must be secured against unintentional contact (e.g. protective grille).
The infrared heater may only be operated with an approved control unit.
When using a control unit that permits a remote start, the cabin must be inspected before activating the “Stand-by for a remote start”.
In case of installation in public saunas or infrared cabins, a control lamp, which indicates whether the infrared heater is switched on, must be provided in the supervisor’s room.
The maximum permissible infrared radiation in a cabin, as defined by EN 60335-2-53, must not be As a result, before installation, use Annex “BB” of the standard to check this requirement and take this into account when selecting the heater power as well as the number of heaters. Or ask your cabin manufacturer.
If the infrared emitter is faulty or broken, it may only be replaced with the identical NARVI emitter model.
If you have questions that are not adequately covered in the installation instructions, contact your supplier.

Safety instructions for the user

The infrared heater must not be used by children under the age of 8.
The infrared heater may only be used by children over the age of 8, by persons with reduced sensory or mental capacities, and by persons with a lack of experience and knowledge under the following conditions: if they are supervised or if they have been shown how to use the infrared heater safely and they understand the dangers that can arise.

Children under 14 years of age may only clean the infrared heater under supervision.
For health reasons, do not use the infrared heater if you are under the influence of alcohol, medications, or drugs.
Before start-up, make sure that the infrared heater is not covered (risk of fire)!
We recommend avoiding infrared radiation within 24 hours of UV radiation from an artificial source or from sunbathing.
Persons at risk of overheating (e.g. cardiovascular diseases) should consult their doctor, in case of doubt, before using an infrared or sauna cabin.
If a permanent erythema (permanent redness of the skin for more than one day) or web-like colour changes remain, the radi- ation should not be repeated and a doctor should be
Before first using the cabin, operate the infrared heater for around 30 minutes and then ventilate well.

Installing the heater

Required tools

Screwdriver/cordless screwdriver with bit TX10
Allen key 2 mm
Saw for the cut-out (e.g. jigsaw)
Measuring tape

Plan the positions of the heater in consideration of the safety distances in chapter 4.2.
Open the cabin wall, e.g. with a jigsaw, in line with the cut-out dimensions (see 4.1 in these instructions).
Remove the infrared heater from the packaging and make sure that no small parts of the packaging remain on the heater.
Remove the glass panel. To do so, use an Allen key to carefully unscrew the two screws (top and bottom of the glass panel) and remove the glass panel by carefully tilting the heater (or using a suction cup). See Figure 5.
Counter-reflector
If you want the infrared heater to evenly distribute the infrared radiation, leave the pre-fitted reflector in the device.
If you want more infrared radiation in the centre of the heater, remove the counter-reflector. To do so, note the instructions in chapter 4.5. $irl-350 -Narvi-Infrared-Sauna-Controller-FIG- $9$$
Remove the counter-reflector, where applicable.
Thread the heater’s connection cable through the opening in the cabin wall.
Position the heater centrally in the cut-out. Make sure that the distance to the wall is the same all around the heater.
WARNING : NARVI infrared heaters have an installed safety temperature limiter. This must be located at the top when the heater is mounted on the wall. Pay attention to the installation orientation of the heater! The terminal box with the cable must be located at the top. See Figure 6.
Screw the infrared heater tight to the cabin wall using the wood screws (3 x 40 mm) provided. See Figure 7.
Reposition the infrared heater’s glass panel and screw tight, applying max. 0.2 Nm of torque.
WARNING: Tighten the screws to fasten the glass panel to max. 0.2 Nm. Otherwise, the glass panel may be damaged $irl-350-Narvi-Infrared-Sauna- Controller-FIG- $11$$

Electrical connection

NARVI infrared heaters are supplied with a pre-assembled connection cable. As a result, the plug (GST18i3) merely needs to be connected to your infrared or sauna control unit.

CAUTION: Note the instructions for use of your infrared or sauna control unit.

Removing the counter-reflector

Remove the glass panel as described on page 15 and 16.
Remove the two screws (M4 x 55 mm) on the reflector with a Phillips screwdriver. See Figure 8.
Remove the counter-reflector.
Reposition the infrared heater’s glass panel and retighten the screws to max. 0.2 Nm. $irl-350-Narvi-Infrared-Sauna-Controller-FIG- $12$$

Troubleshooting

Description of error	Solution
The infrared heater is not illuminated or is not heating.	Check whether the

plug is correctly connected to the control unit.

Check whether the control unit is work- ing correctly. If necessary, contact the control unit manufacturer.

In rare cases, the cause may be a faulty infrared emitter.

The infrared heater constantly switch- es off during operation.| Check whether an adequate volume of air can circulate on the rear of the radiator.

If the ventilation is adequate, the safety temperature limiter (STL) may be faulty. In this case, contact your retailer.

Insufficient heat is emitted.| Check the set dimming level on your control unit.

If the heat is constantly too low, remove the counter reflector as described in 4.5.

The heating effect or light distribution is too uneven for your preferences.| Fit the counter-reflector.

Start-up
Before initial use
Before first using the cabin, operate the infrared heater for around 30 minutes and then ventilate well.

Infrared heater as “back heater”
If you are using the infrared heater for the back, a protective measure, such as a suitable backrest, must be used to prevent unintentional contact.

CAUTION: Ensure a minimum distance of 40 mm between the surface of the skin and the infrared heater.

Infrared heater as “front heater”
When used as a front heater, make sure that you do not permanently stare into the heater.

CAUTION: Do not stare into the heater for an extended period of time.

Cleaning

Clean the front of the infrared heater with a soft cloth and warm water as necessary.
Do not clean using steam cleaners, high-pressure cleaners or spraying water.

Disposal
The packaging materials must be disposed of in accordance with the applicable guidelines. Old devices contain recyclable materials as well as harmful substances so do not dispose of these as residual waste; ensure compliance with the applicable regulations.
