4. Record the brine level on the Installation Checklist It is normal for the brine level to drop somewhat during transport however if no brine is visible in the monitor contact Tank Solutions WARNING Always secure the tank before moving or lifting it This is commonly done by connecting a crane to the lifting lugs Failure to do so could result in death or serious injury WARNING While moving or lifting the tank do not position any part of your body underneath the tank This could result in death or serious injury If damage is detected do not attempt repairs Contact the Production Manager at Tank Solutions on 02 4964 8270 After installation and before backfilling to grade testing must be repeated to verify that no damage has occurred during installation Remove all temporary service fitting plugs and the reservoir fitting plug Check the monitoring fluid level in the reservoir It should be about 1 full Visually check the interior of the tank for monitoring fluid There should not be any Replace the protective covers in the service fitting and the reservoir fitting 3 BACKFILL AND BEDDING Tank Solutions recommends tanks be installed using either pea gravel or crushed stone which meets the following specifications GENERAL The material is washed and free flowing and confirms to the specification of AS2758 and AS1141 No more than 5 by weight of the material may pass through a 2 36mm sieve Tank Solutions Fibre
