level/filling pressure of the system as well as on meth-
ods of refilling and venting the heating system when
needed.
• Point out to the user the correct (economical) settings
for temperatures, controllers and thermostat valves.
• Instruct the user on the need for yearly inspection
and maintenance of the system. Recommend making
a maintenance contract.
