Solution: The position of the Trigger should be on the left or right hand side of the delivery tube and not at the back of the Unit.

This may or may not be a problem and depends on the following conditions.

Solution: During normal operating conditions, if the Unit is left standing for a period of time the constant evaporation of the Liquid Nitrogen inside the bottle will result in the temporary opening of the Relief Value venting the excess pressure. This "hissing" is also heard when the Unit is picked up. THIS IS NOT A PROBLEM. The Relief Valve is just operating as designed.

If the Exterior of Bottle is frosting over there will be excessive Relief Valve activity (hissing). THIS IS A PROBLEM. The vacuum inside the bottle has deteriorated due to age or the bottle has been damaged. Replacement of Bottle is necessary. Return the complete Cryosurgical Unit to an Authorized Repair Center.

Solution: Valve Stem sticking. Depressurize the unit immediately by unscrewing the top a quarter to one half turn. Lubricate valve stem as detailed in Section 5, Maintenance .

Solution: Spray Tip may be clogged. Remove tip. If the Cryosurgical Unit sprays without a tip, clean the opening of the tip with a fine needle or bang the tip gently on a table or counter to dislodge any foreign matter. Then check the Liquid Nitrogen supply for contaminants that can clog the tips and unit. (see Section 4, Liquid Nitrogen, paragraph 2 for information on how to keep Liquid Nitrogen supply clean).

The Unit has been over filled and there is insufficient air space inside the bottle to create an adequate build up of pressure to enable that is required for the Liquid Nitrogen to spray.

Check that the Gasket is in place inside the cover and is not split or missing. Always ensure you have spare Gaskets available.

Solution:  If the Exterior of Bottle is frosting over there will be excessive Relief Valve activity (hissing). THIS IS A PROBLEM. The vacuum inside the bottle has deteriorated due to age or the bottle has been damaged. Replacement of Bottle is necessary. Return the complete Cryosurgical Unit to an Authorized Repair Center.
