• Do not use this micro-boiler if any part has been submersed under water.
Immediately call a licensed professional to inspect the micro-boiler to
replace any damaged parts.
• Do not reverse the hot outlet and cold inlet connections to the micro-
boiler. This will not properly activate the micro-boiler.
CAUTION
• All pipes, pipe ttings, valves and other components, including soldering materials, must be
suitable for space heating systems.
• We recommend using an isolation valve set with hose bibs for serviceability. See maintenance and
service section. Contact Hydro Smart at 1-763-331-3066 to order a isolation valve/service kit.
