Criterion 6.4.6 Maintenance and Servicing

Criterion text:
All individual components of the system which may require periodic examination, adjustment, service and/or maintenance shall be easily and safely accessible by the owner and in accordance with the codes in force at the installation site. Individual collectors in any array shall be replaceable or repairable without disturbing any other collector in the array.

Comments:
The installer must be aware of the requirements of this criterion during system installation. The system must be installed in such a manner that allows access on the part of the system owner as well as future service personnel. Common sense should dictate whether system components are indeed accessible.

In turn, installers should also tell the system owner to avoid storing items around the solar system. The situation in Figure 1 will make it very inconvenient for anyone who has to get close to the water heater and those solar system components adjacent to it.

Figure 1

Installers must use the appropriate interconnection fittings and plumbing techniques listed in the SRCC approved manufacturer's installation manual. Figure 2 shows the collector interconnection fittings provided by a manufacturer. These allow the installer to replace or repair a collector without disturbing any other collectors in the array
