PRECAUTIONS WITH HARTGARD FOR BUILDING WITH RAINWATER TANKS

While Hartgard is non toxic to humans, it does have an adverse effect on water stored in rainwater tanks. Hartgard will kill
microscopic algae that is typically present in rainwater tanks. This may then render the rainwater foul and unfit for human
consumption. Solahart recommends that installers ensure that rainwater tanks cannot be contaminated with Hartgard
solution. Before installing a closed circuit system, the installer should determine whether the run-off from the roof on which
the system will be mounted, is collected in a rainwater tank.
If this is the case, then the section of gutter immediately beneath the proposed location of the new Solahart system should
be isolated from the rainwater collection system. This can be done by blocking that section of gutter from the remaining
gutter, and fitting a separate down pipe to take any run-off water from that section of roof away to waste. If this is not
practical for a specific installation, then the installer should discuss the possible options with the home owner.
This should be done prior to installing the new system, so that any leak or spillage during installation does not make its way
into the rainwater tank. If a rainwater tank does become contaminated, then the following actions are necessary to return the
water supply to a consumable state.

Correct the leak or spillage.
Wash down the roof area where the spill or leak has occurred.
Flush out the gutters and down pipes.
Empty the rainwater tank, and clean out all algae from the inside of the tank.
Refill the rainwater tank with fresh water.

CLOSED CIRCUIT INDIRECT SYSTEMS – END CAP

The end cap is supplied fitted to the „tail‟ end of the tank. The end cap used should not need to be removed to complete the
installation.
Removing the End Cap
If it is necessary to remove the end cap:
Remove the screw from the end cap
Using a flat faced screwdriver, gently lever the end cap out of its recess from the key slot at the bottom of the end cap.
Fitting the End Cap
To fit the end cap:
Position the end cap in the jacket end recess, lining up the slot at the bottom of the end cap with the key on the jacket
end.
Gently push into the recess so the end cap engages with the ridges on the jacket end.
Secure the end cap with the screw provided, taking car
