11. Maintenance & Repair
The solar collector is virtually maintenance free. Other system components such as the pump, heat transfer fluid
(closed loop only) require periodic inspection and may need to be replaced in the future. Please refer to the
documentation provided by the manufacturer of these other components.
Apart from maintenance specifically outlined as “HOMEOWNER”, any maintenance or
repair MUST ONLY be performed by Authorized Persons. At no time should any inspection
or maintenance be performed by the homeowner, if it involves climbing on the roof or any
potentially unsafe behavior. The solar collector warranty will be void, if non-Authorized
Persons attempt to maintain or repair the solar collector or associated system components.
The solar system operates at high pressure and high temperature and can cause damage
to property and severe personal injury, if not correctly operated and maintained.
Periodic inspections by an Apricus Authorized Person is recommended to ensure optimum system operation.
The following basic maintenance or inspection MAY be completed by the HOMEOWNER
11.1. Cleaning (HOMEOWNER)
In most cases, periodic rain will keep the evacuated tubes clean. If particularly dirty, they may be washed
from a safe location with a high-pressure water spray. If the collectors are located where they are easily and
safely accessible, a soft cloth and warm, soapy water or glass cleaning solution may be used.
During autumn, leaves may accumulate between or beneath the tubes. Please remove these leaves
regularly to ensure optimal performance and to prevent accumulation of ignitable material (if in high fire risk
area). The solar collector will NOT cause the ignition of flammable materials. Such cleaning may only be
completed by the homeowner if the tubes are easily and safely accessible (refer also to 3.1 for safety
considerations)
11.2. Inspection (HOMEOWNER)
If there is any problem with the system, the installer will, generally, ask the homeowner to inspect various
portions of the system before making a service call. The following inspections may be performed by the
homeowner, ONLY if they are easily and safely accessible. The homeowner should be given a copy of the
Owner’s Manual which outlines these maintenance procedures.
a) The pump station foam casing may be removed (pulled toward you and off) to check the following system
information:
i) Pressure gauge reading
ii) Temperature gauge reading (both of these are on the different portions of the same gauge)
iii) Pump operation (i.e. sound)
iv)Flow meter reading
b) Visual check for degradation of pipe insulation
c) Visual inspection of solar collector tubes
