pacemaker before using this underblanket.

• this underblanket may not be used by children unless 

the switch has been preset by a parent or a supervisory

  person, or the child has been sufficiently instructed in 

how to use this electric underblanket safely.

• the electric underblanket should not be used with 

persons who are helpless, small children or persons 

insensitive to heat (e.g. diabetics, persons with skin 

changes related to illness or persons with scarred skin in 

the area where the blanket is to be applied, after taking 

any pain-relieving medication or alcohol).

• the electric underblanket must not be used with 

persons who are incontinent. 

• this electric underblanket is intended for warming 

beds.

• this electric underblanket is not intended for use in

Over the past several years the number of people allergic 

to house dust and dust mites has increased dramatically. 

Irritation of the eyers, attacks of sneezing and coughing 

and shortness of breath in the early morning hours are 

typical symptoms of this type of allergy. these reactions 

are triggered by the proteins in the excrement of the 

dust mite. Mites are virtually ever-present in a moist, 

warm micro-climate, as often predominates in beds. they 

primarily feed on human skin scales and molds that can 

be found in every household. Even with regular, thorough 

cleaning, dust and skin particales constantly accumulate.

What preventative measures can you take?

you should avoid any contact with dust mites if possible. 

Our breathing, machine-washable anti-allergenic 

underblanket helps you do this. this combination of 

specially coated underblanket and contour sheet is 

equipped with the following components:

ACTIGARD® finish

The surface with an ACTIGARD® finish prevents mites 

from multiplying and protects against their allergens. In 

addition, aCtIgaRD® also reduces the formation of mold 

and unpleasant odors caused by bacteria and fungus.

Mite insulation layer and mite-proof bed border

the mite insulation layer, a pUR membrane integrated 

directly under the cotton surface and the mite-proof bed 

border reduce your contact to the allergy-causing dust 

mites and their excrement. In addition, this special finish 

also helps reduce mites by cutting them off from their 

supply of food.

Heat

You can specifically fight mite populations that already 

exist with our heat underblanket. the temperature you 

produce by setting the switch to level 6 (anti-allergy 

level) of the heat underblanket dries your mattrass, and 

therefore creates a ‘mite-hostile’ micro-climate on the 

mattress surface. We recommend you use the anti-allergy 

level regularly. Ideally, the heat underblanket should be 

operated for several hours. the automatic switch-off time 

of 12 hours is especially well-suited for this purpose. to 

prevent the heat from escaping, the heat underblanket 

should be completely covered during this process.

Before you use the underblanket for the first time, please 

do as follows: carefully unpack the underblanket and 

remove all the packaging material. Keep the material 

(plastic bags and cardboard) out of reach of children. 

Check the underblanket after unpacking for any damage, 

possible from transportation. 

never switch the electric 

underblanket on when folded or compressed, wedged 

between objects and never make any sharp creases

. 

Do not place any artificial heatsources or heavy objects 

on the electric underblanket.

this electric underblanket is intended for warming 

beds. the electric underblanket heats up best when it is 

switched on while it is covered with a quilt. the heating 

up time with the electric underblanket covered is approx. 

15 minutes.

This electric underblanket is fitted with the INVENTUM 

SafEty SyStEM (tSS). this electronic sensor technology 

prevents the entire surface of the electric underblanket 

from overheating by automatically switching off in the 

event of a fault. If the safety system switches off the 

electric underblanket automatically as a result of a fault, 

the indicator lamp is no longer illuminated even when

the electric underblanket is switched on. please note 

that, after a fault has occurred, the electric underblanket 

can no longer be used for safety reasons and must be sent 

to the service address indicated.
