DRAIN TREATING AGENT INJECTOR FOR CEILING TYPE AIR- CONDITIONING INDOOR UNIT

摘要

PROBLEM TO BE SOLVED: To perform injection work surely even when the surroundings of a drain pan is limited by lessening the burden of drain treating agent injection work. SOLUTION: A drain cap 5 with a check valve disposed on the bottom at the lower section 3 of a sub-drain pan is coupled with a push-out type injector 7 through a removable coupling 27 and then a desired quantity of a drain treating agent is delivering and injected from the injector 7. Since the drain treating agent can be injected without dismantling the sub-drain pan B and the drain cap 5 with a check valve disposed on the bottom of the sub-drain pan B can be accessed easily from the indoor side, injection work is facilitated and can be executed surely even when the surroundings are limited without removing a decoration panel 1.
