Measure the hot water delivery temperature with a
suitable thermometer at an untempered outlet closest
to the gas booster. The temperature should be between
65°C and 70°C.
Measure the hot water delivery temperature with a suitable
thermometer at a tempered outlet. The temperature
should be 45°C or 50°C as outlined in section “Water
Pipes, Valves and Fittings” within this section of these
instructions.
Close the isolating valve on the cold water supply to the
hot water storage tank. Inspect and clean the strainers at
the isolating valve and gas booster inlet.
Solar Collector
Check that the solar collectors are correctly anchored to
the roof and that all tiles and flashings/seals are in place.
Check that hot and cold temperature sensors are correctly
positioned and the leads are free of cuts and damage.
Remove plastic covers from the solar collector/s.
For gas boosted Stratco Solarcore
TM
hot water heating
systems, turn on the power supply to the gas booster
and the temperature differential controller. Ensure the
isolating valve on the cold water supply and the isolating
valve on the gas supply to the gas booster are both open.
For electric boosted Stratco Solarcore
TM
hot water heating
systems, turn on the power supply to the electric heating
element/s and the temperature differential controller.
Ensure the isolating valve on the cold water supply is
open.
Solar heating of the water in the hot water storage tank
will now commence automatically when there is sufficient
sunlight.
Handover
Once commissioning has been successfully completed,
show the owner the main Stratco Solarcore
TM
hot water
heating system components and explain their correct
operation as outlined in “Operation” section of these
instructions. Also explain the importance of correct
maintenance as outlined in “Maintenance” section of
these instructions.
Complete the installation report form and fax it to Stratco.
Complete the RECs assignment form in conjunction with
the owner and fax it to Stratco.
Leave this instruction manual with the owner and ask
them to complete the warranty form and return it to
Stratco.
For longer absences, the electric element or gas booster
can be turned off as follows:
•
For electric boosted systems, switch off the electricity
supply to the electric boost heating element in the
electricity meter box. To ensure frost protection do
not switch off the power points for the electronic
controller, circulating pump or the water supply.
•
For gas boosted systems, switch off the power points
for the gas booster. To ensure frost protection do
not switch off the power point for the electronic
controller and circulating pump or the water supply.
During extended absences in summer it is advisable to
cover the solar collector to avoid overheating the system
and dumping hot water from the P&TR valve.
Turning On the Stratco SolarCore
TM
Hot
Water System After Holidays
For electric boosted systems, switch on the electricity
supply to the electric boost heating element in the
electricity meter box. Check that the power points for the
electronic controller and circulating pump are still turned
on. Remove covers from the solar collectors if covered.
Electric heating will commence automatically but it may
take several hours before hot water is available.
For gas boosted systems, switch on the power point for
the gas booster. Check that the power point for the
electronic controller and circulating pump is still turned
on. Remove covers from the solar collectors if covered.
Hot water will be available immediately from the gas
booster.
General Use
The Stratco Solarcore
TM
hot water heating system is
designed to automatically provide a continuous supply of
hot water, while maximising the environmental benefits
and energy cost savings achieved with solar heating.
The electronic controller automatically switches the solar
heating function on when there is sufficient heat available
from the sun. When the water in the hot water storage
tank reaches 65°C the electronic controller switches off
the solar heating function and protects the hot water
storage tank from overheating.
The electronic controller also automatically protects the
solar collectors from damage during freezing weather
conditions.
During periods when there is insufficient heat available
from the sun, the gas boost heater or electric boost
element will automatically provide all the heat necessary
to ensure a continuous supply of hot water.
Apart from the regular care outlined in “Regular Care”
within the “Maintenance” section of these instructions,
there is no action needed by the user of the solar hot
water heating system. All the user needs to do is open a
tap or turn on an appliance to enjoy the benefits of solar
heated hot water.
Turning Off the Stratco SolarCore
TM
Hot
Water System for Holidays
If the premises will be unoccupied for a few days, Stratco
recommend that the solar hot water heating system is
left switched on.
