11.8. Freezing

a) If the pump or controller fails or a power outage occurs, during an extended sub-zero period, a direct flow

(water) system may suffer from freeze related damage. This can be indicated by no pump flow due to pipe

blockage or, after the system thaws out, leaking due to a burst pipe.

b) Exposed copper piping, particularly near elbows or connections is the most likely location for freeze

damage to occur. Once the system thaws, leaks will need to be repaired.

c) To repair, isolate flow to the collector or drain the system and repair/replace any damaged piping, then re-

commission the system. An air test is recommended before recommissioning. Refer to 7.10 and 8.9 for

instruction on draining the system.

d) If freezing is a regular occurrence, a closed loop system is a better option for the climate and the system

should be converted.

11.9. Maintenance Plan

It is recommended that as a minimum the following maintenance plan is followed:

Component

Time Frequency

Inspection

Insulation

3 years

Check for degradation

Controller

3 years

Check data-logger operation, system settings.

Pump operation

3 years

Check ﬂow rates, pump noise, vibration etc

Solar Collector

3 years

Check tubes for any vacuum loss

Heat Transfer Fluid

1 year

Check appearance, pH and hydrometer reading.

11.10. Maintenance Equipment

In order to allow efficient completion of maintenance activities, the following equipment should be kept on site, if

applicable to the system configuration.

a) Automatic Air Vent - this should have been removed after initial filling of the system. It should be kept on

site in a sealed plastic bag,cable tied to the tank or pump station piping and marked as follows:

“Automatic air vent for highest point of solar collector loop. DO NOT discard and DO NOT install

permanently.”

b) Copies of the installation manuals, MSDS sheets and any other documentation supplied with the

components of the system.

c) A copy of system diagram along with notes of any non-standard or notable aspects of the design. See

Apricus OG-300 Systems Manual for system diagrams.

d) Labeling of key components and piping. See also 3.24.

11.11. Replacement Parts

For all major component replacements, contact the local Apricus dealer or distributor or contact Apricus Inc. via

email at [email protected] or phone 877-458-2634.
