If hoses or special collector connectors were used, disconnect and save them.
Unless you are absolutely sure new hose or connectors are available that are
compatible with the solar temperatures and fluid, it is better to reuse the old ones.
To replace or repair the absorber plate, it is easiest to remove the entire collector.
Disassemble the collector until the absorber can be removed. Store the empty
collector in a dry, safe location until the repair is completed.
Before installing a new absorber into the collector, it may be worthwhile to pressure
test it. Use compressed air, and keep the absorber out of the sun. One hour is an
adequate time period. The test pressure should be approximately the same as that
of the collector loop pressure relief valve setting.
If you know the brand of absorber or collector, Tables 5-2 and 5-3 will be of help. If
you do not know, move ahead to the general repair information which follows the
tables.
