󱚡 WARNING

The following maintenance may ONLY be completed by Authorized Persons

11.3. Broken Tube

a) If a tube breaks, it should be replaced, as soon as possible to maintain maximum collector performance.

b) The system will still operate normally and safely even with a tube broken.

c) Always wear safety goggles and gloves when handling broken glass. Any broken glass should be cleared

away to prevent injury.

d) To replace a tube:

i) Remove the tube clip(s), slide broken tube out and carefully pick up any glass pieces. Protective

gloves and safety glasses must be worn when handling broken glass.

ii) Avoid touching the glass wool insulation with bare hands, as it can cause mild skin irritation. Wear

gloves.

iii) If the heat pipe is not easily removed (commonly the case), it can be left in place and a new

evacuated tube inserted, guiding the heat pipe down the groove between the evacuated tube inner wall

and heat transfer fin. If the heat pipe is easily removed, the easiest option is to replace the heat pipe

and evacuated completely.

11.4. Insulation

a) The pipes running to and from the collector should be completely insulated. Insulation should be checked

periodically (at least once every 3 years) for damage or gaps, especially exterior EPDM foam insulation.

b) For any insulation that is exposed exterior conditions, (sunlight and water), ensure protective cover/wrap/

foil is in good condition, replacing as required.

11.5. Heat Transfer Fluid

a) Heat transfer fluids that are exposed to stagnation temperature may break down over time, which will

cause the fluid to become acidic and lose anti-freeze properties. It will general become “sludgy,” which can

reduce circulation efficiency. Refer to 3.31 for more information on heat transfer fluids or consult the

manufacturer of the fluid or see Appendices 11-18.

b) Ideally, heat transfer fluid should be inspected and tested annually, but least once every 3 years. The

following checks should be completed:

i) Check for cloudiness or sludging that would indicate fluid breakdown

ii) Check pH, should be within the range specified by the manufacturer

iii) Use hydrometer to check freeze protection level

11.6. Draining the Collector

a) During system maintenance or in preparation for extremely and/or extended cold conditions, draining the

collector manifold may be required. If the building is going to be vacant for longer than 45 days at a time,

the system must be drained and the collectors covered with a tarp. Refer to sections 7.10 and 8.9 for

specific instruction on draining.

11.7. Other Components

a) Other parts of the system such as the storage tank and the electric, gas or tankless water heater or boiler

should be serviced and inspected according to their specific manufacturer’s maintenance guidelines.
