5. Maintenance and Service
4.
During the maintenance and other kind of work a collector must be placed firmly
to exclude the danger of tripping over and falling down,
5.
It is not allowed to perform any repair and maintenance work under a lifted
collector which has not been protected against casual falling down,
6.
Repair and maintenance work should be done by means of suitable tools and the
servicing personnel should wear protective gloves and shoes,
7.
Before the commencement of maintenance work it is necessary to wait till the
temperature of a collector lowers to such an extent that a risk of getting scalded
by hot elements is excluded,
8.
Overhaul of the solar system needs to be done in accordance with warranty
recommendations for particular elements of the system.
In order to guarantee failure-free operation of the whole system it is
recommended to carry out the following maintenance work at least once a year:
1.
Frost protection – check the solar fluid resistance to frost by means of a control
device (refractometer). In case of a significant fall in frost resistance of the solar
fluid it should be replaced and the system must be deaerated once again.
2.
System pressure – working pressure in the solar system needs to be checked.
After the start-up period no drop of pressure is permissible.
3.
Expansion vessel – input pressure of the expansion vessel should be checked.
To this end, disconnect the vessel from the system and measure the pressure. The
input pressure should be 2,5 bars.
The control and protection system should also be inspected along with the
structure for supporting and fixing a collector on the roof.
In order to guarantee the proper operation of the whole system, every time we
recommend you to enter into a contract for maintenance work with a specialist
installation firm.
