We recommend that you vacuum off your mattress before 

using the heat underblanket for the first time. Then 

spread out the heat underblanket flat on your mattress 

so that the cable entrance is located approximately at 

shoulder height (see illustration). 

the head area of the anti-allergy 

underblanket is not heated.

then pull the side section over 

the sides of your mattress like a 

contour sheet. the underblanket 

is designed to fit mattresses of the 

size 35x80 inch (90x200 cm) and 

38x80 inch (100x200cm).

then secure your contour sheet 

as accustomed so that the 

underblanket is between your 

mattrass and the contour sheet. 

Make sure that the underblanket 

is always spread out flat and does 

not get pushed together or wrinkle 

during use. Check its position when making the bed. the 

electric underblanket may only be switched on when it is 

spread out flat.

We recommend switching on the electric underblanket 

and covering it with the quilt for approx. 15 minutes 

before going to bed to prevent the heat from escaping. 

this electric underblanket may only be operated in 

conjunction with the switch type specified on the unit.

attention: the electronic components in the switch will 

cause the switch to warm up slightly when the electric 

underblanket is being used. for this reason, the switch 

must never lie on the electric underblanket or be 

covered by blankets, pillows etc.

you will obtain the most rapid heating-up of the electric 

underblanket by setting the highest temperature level 

at the beginning. a lower setting can be selected later if 

required.

O = Off

1 = Minimum heat

2-5 = Individual heat

6 = Maximum heat and 

anti-allergy level

With this underblanket an automatic switch-off 

after approx. 2, 6, 9 or 12 hours can be set. the 

red controllamp in the switch lights up while the 

underblanket is being heated. after the switch-off time 

expires, the underblanket is no longer heated and the 

red controllamp begins to flash. To heat the underblanket 

again, first set the switch to the switch setting 0 (off) 

for approx. 5 seconds and then select the desired 

temperature setting. If the underblanket is no longer 

used after the timed switch-off, it should be switched off 

(level 0) or the power plug should be pulled out of the 

socket outlet.

5 | use

always remove the power plug from the power supply 

before cleaning the electric underblanket. Smaller stains 

can be removed using a cloth or moist sponge together 

with a little liquid detergent for delicate fabrics if 

necessary. 

do not use any cleaning agents containing 

solvents on the underblanket.

this electric underblanket is machine-washable. 

Before the washing cycle, first disconnect the plug 

connection and thus remove the plug from the electric 

underblanket (see illustration). 

Set the washing machine to a delicate 

wash cycle at 60°C. Use a mild 

detergent with dosage according 

to the manufacturer’s instructions. 

Only reconnect the switch to the 

electric underblanket after the 

plug connection and the electric 

underblanket are completely dry. 

Note that the electric underblanket will suffer from 

too frequent washing. for its entire life, therefore, the 

electric underblanket should be washed not more than 

1 or 2 times a year. Note that the electric underblanket 

must not be dry cleaned, wrung out, machine dried or 

ironed. On no account switch on the electric underblanket 

to dry it. Do not hang up the electric underblanket with 

clothes pegs or similar to dry it.

If you are not going to use the electric underblanket 

for some time, we recommend storing it in its original 

packaging in a dry place without weighing it down.
