allow the collector temperature to drop. Another option is to complete the work before sunrise, or after

sunset.

Step 2. Once collector temperature has dropped to below 113

F (45

C) turn the solar controller to

Manual mode so the pump and boosting does not turn on, but leave power on.

Step 3. Connect garden hose to left hand drain valve and run pipe to a suitable drainage point, such

as a drain or bucket with capacity of at least 4 gallons (or more depending on the pipe run length)

Step 4. Turn off the isolation valve beneath the pump with the yellow handle, and the one on the right

hand side with red handle. Immediately turn off the power supply to the controller which which will

open the Power Outage Drain Valve, helping to drain the solar collector piping.

Step 5. Open the left hand drain valve to allow the water to drain from the collector. Open the ball

valve where the auto-air vent mounts to allow air to enter the top of the piping.

Step 6. Once the system is fully drained maintenance work can be completed. Handles should be

removed from the two closed isolation valves to avoid accidental opening which would release high

pressure and potentially hot water.

c) SINGLE TANK SYSTEM - DRAINING TANK AND COLLECTOR:

The following drainage procedure applies to a single tank that is both heated by solar and some other

heating source. For any other single system formats, refer to standard plumbing practices in accordance

with local codes, or if unsure, contact Apricus.

Step 1. Cover the solar collector to prevent exposure to sunlight. At least 30 minutes is required to

allow the collector temperature to drop. Another option is to complete the work before sunrise or after

sunset.

Step 2. Turn OFF and disconnect from power supply any auxiliary boosting (electric, gas or other) that

acts on the solar storage tank. Do not disconnect power supply to the solar controller.

Step 3. Once collector temperature has dropped to below 113

F (45

C) turn the solar controller to

Manual mode so the pump and boosting does not turn on, but leave power on.

Step 4. If the tank contains hot water, turn on one or more hot water taps in the building and run until

the hot water has been depleted.

Step 5. Turn off the main’s pressure cold water supply to the storage tank and open a hot water tap to

allow air to enter the tank.

Step 6. Open the drain valve on the tank - ensure it is draining to a suitable location via gravity or

pumped. Open the ball valve where the auto-air vent mounts to allow air to enter the top of the piping.

Step 7. Disconnect power supply to the controller which will open the Power Outage Drain Valve and

help to drain the solar collector piping.

Step 8. Once fully drained, the system repairs/maintenance can be completed and then, the fill

process above is repeated to return the system to service.

d) TWIN TANK SYSTEM (Solar Feed) - DRAINING FIRST TANK AND COLLECTOR:

The following draining procedure applies to twin tank systems that a solar pre-heat tank with no auxiliary

boosting that feeds into a secondary tank with auxiliary boosting. The plumbing design must allow the solar

tank to be isolated such that the second tank can continue to supply hot water to the building. For any other

system format, refer to standard plumbing practices in accordance with local codes, or if unsure, contact

Apricus.

Step 1. Cover the solar collector to prevent exposure to sunlight. At least 30 minutes is required to

allow the collector temperature to drop. Another option is to complete the work before sunrise, or after

sunset.

Step 2. Once collector temperature has dropped to below 113

F (45

C) turn the solar controller to

Manual mode so the pump and boosting does not turn on, but leave power on.

Step 3. Connect a drain pipe to the tank drain port and run to a suitable drain location. The water in

the storage tank may be hot, so care should be taken to avoid scalding.

Step 4. Isolate the solar storage tank from the second tank. The second tank should be able to
