16. DESCRIPTION OF PROCEDURES FOR ANNUAL PREVENTION CHECKS

Warning:

Prevention examination and eventual

intervention may be carried out by a quali

person only. Any work on electric wiring may
be done by an authorized electrician. Maximum
care shall be taken during checks. In case the

procedure requires a person to get on a roof, a fall arrest
is necessary.

Check procedures

Year 1 Year 2 Year 3 Year 4 Year 5 Year 6

Check the pressure in expansion vessel, replenish if necessary

Check system visually for leaks

Check the collector glazing cleanness, wash if necessary

Check ambient trees for possible shading

Check

pipe

insulation

Check the proper

rate

Check

temperature

probes

Check the quality of antifreeze liquid (with a refractometer)*

Check the heat carrier pressure, replenish if necessary

Check the controller settings

Check for possible error messages in the controller and their reason

Check

wiring

Check backup heating function (el. heating rod, gas-

red boiler)

Check the magnesium anode rod in the tank, substitute if necessary
(see

Instruction

Manual)

Check the function of all system valves and

ttings

Check the collector

xing

If needed, check the pressure in the heating system expansion vessel

If needed, clean the

lter and de-aerate the heating system

Preventive training in system maintenance and controller setting
for the operating staff

*If the test result shows the necessity, fi ll new heat carrier.
