Page 11: Cleaning
After prolonged use or when the apparatus is very dirty the following procedure should be carried out by a person authorized by INTERSPIRO: 1. Close the cylinder valve and switch on the positive pressure. - Page 12 5. Dismantle the breathing valve in the following way: a) Unscrew the locking ring and re- move the positive pressure unit from the valve housing. b) Seal off the connection nipple and the inlet channel with rubber plugs. c) Hold the positive pressure unit and loosen the diaphragm assembly by squeezing the thread of the cover.
- Page 13 e) Remove the positive pressure spring and the guide disc from the positive pressure unit cover. d) Remove the sealing disc and the exhalation diaphragm from the dia- phragm assembly. Do not disman- tle the diaphragm assembly any further. e) Remove the protective ring from cover if necessary. Further dismantling of the breathing valve should only be carried out by an authorized service man.
- Page 14 6. Wash the face mask and the breathing valve dismantled as described above. Use soap and warm water (maximum 40 °C). Scrub with a brush if necessary. Instead of soap a detergent can be used. Note! Strong detergents should be avoided as these may damage rub- ber and plastic materials.

Page 15: Assembly After Cleaning
ASSEMBLY AFTER CLEANING 1. Check that the rubber parts are supple and without cracks or other defects. Damaged parts should immediately be replaced. Any repairs to the breathing valve should always be followed by a function test on the test equipment. 2. -
Page 16: Function Test After Cleaning
FUNCTION TEST AFTER CLEANING 1. Connect the breathing hose to the breathing valve and push the lever to the off position (i.e. against the valvehousing). Open the cylinder valve. No flow of air should be heard. A flow indicates a leakage. 2. -
Page 17: Diving In Low Water And/Or Air Temperatures
Diving in low water and/or air temperatures Colder environments always involve greater risk of freezing in a breathing ap- paratus. We recommend the use of the full-face mask at low temperatures be- cause it provides better protection for face against cold. It is also physiologically correct because the inhalation air is warmed and moistened in the nose. -
Page 18: Face Mask
2. Face mask The face mask has been developed in order to protect the diver's face against cold and to make it possible to warm and moisten the breathing air on its way through the nose before it reaches the lungs. The DIVATOR MK II full-face mask has completely separated inhalation and exhalation channels. - Page 21 SWITZERLAND: Interspiro AG, Güterstrasse 47, CH-4133 PRATTELN.
