Document #050614001 5 M-48 SuperMask User Guide Introduction Congratulations for choosing the Kirby Morgan SuperMask®. The SuperMask represents years of development and testing. Development of this mask could not have been possible without the help of the diving com- munity as a whole. The original goal was to develop a modular full-face mask that could offer greater comfort and safety to divers using self-contained breathing apparatus. When the mask is used with a rebreather, it is normally used with a DSV (Dive Surface Valve), which you may also hear referred to as the rebreather’s “mouthpiece.” Dive Surface Valves are mechanisms that contain the shut off valve that connects the inlet and exhaust hoses on a rebreather. The mouthpiece for the diver normally connects to the DSV using a cable tie. The mouthpiece mounting tube is where the DSV interfaces with the M-48 mouthpiece pod. The SuperMask, was designed for use with rebreathers, as well as open circuit SCUBA, and lightweight umbilical supply. The SuperMask has been tested and certified by Dive Lab Inc. Configuration in both open and closed circuit mode have been tested and approved for use by U.S. military organizations KMDSI will continue to develop the mask as well as additional pods and accessories. Users should routinely check the KMDSI web page for additional information. Questions on the use and care of this mask should be addressed to Kirby Morgan Dive Systems Inc. Telephone 805-928-7772 or e-mail at www.kirbymorgan.com or Dive Lab Inc, Telephone 850-235- 2715 or e-mail at www.divelab.com. DANGER Kirby Morgan Dive Systems, Inc., cannot guaran- tee the diver protection from contaminants when using the SuperMask in waters that are biological- ly, chemically or radioactively polluted. Radioac- tive, chemical, and biological contaminants can cause serious, permanent bodily harm or death to the user. While the SuperMask can minimize and help re- duce the risks associated with the exposure to certain waterborne chemical and biological con- tamination, it cannot protect the user in all situa- tions or against all contaminants. 6 © 2005 KMDSI. All rights reserved. Document #050614001 M-48 SuperMask User Guide WARNING Not all SCUBA regulators or rebreather DSV’s (mouthpiec- es) will fit the M-48 mouth pod. The size of the mouthpiece mounting tube as well as the placement and size of the ex- haust tee can affect the mounting and proper functioning of the mouthpiece and folding action on the pod bellows. Additionally, it is extremely important that the demand reg- ulator or DSV being fitted does not have any sharp edges that could cut the pod skirt or mouthpiece orifice. The SCUBA regulator or DSV must not interfere with the fit of the mask, and all components must be fully functional. Do not use any component with the mask or pod if the com- ponent or mask functions are compromised in any way. WARNING Use only mouthpieces with the appropriate dimensions and characteristics for the M-48 mask pod and the breath- ing apparatus you have selected. Use of other mouthpieces may cause an insecure fit which could lead to separation of the mouthpiece from the pod, resulting in a flooded pod and drowning. WARNING Diving this mask in water containing concentrations of pe- troleum based chemicals could cause degradation of the components of the mask. Clean the mask using only a so- lution of one (1) tablespoon of a mild hand dish washing detergent, such as Joy ™ or Palmolive ™, to one gallon of water. WARNING Cold Water Diving (water Temperatures below 450F or 100C) requires specialized training and equipment. Do not at- tempt diving in cold water unless you are properly trained and equipped for this type of specialized diving. © 2005 KMDSI. All rights reserved. Document #050614001 7 M-48 SuperMask User Guide WARNING The SuperMask is NOT equipped with a one-way valve (non-return valve) for surface-supplied diving. When using the mask for surface-supplied diving it must be used with the KMDSI manifold block KMDSI PN# 300-150 or 300-155 and a suitable harness and emergency gas supply system. Without the non-return valve, the diver could be subject to a “squeeze” if the umbilical supply is severed.
