INTRODUCTION
On-site pre-installation preparations
The following items should be set up on site before the installation of the filtration system.
Electricity connection
The BackFlush controller is supplied in either of two versions:
• 110-240v AC input - powered by an external 110-240v AC to 12v DC power supply.
Requires a mains electricity supply - 110-240v AC ~, 50/60 Hz 0.4 A Max.
Ensure that a suitable electrical power supply is available in the vicinity of the BackFlush controller.
The mains electricity supply should be equipped with a readily accessible circuit breaker, rated according
to the BackFlush controller's total rated power for peak demand, certified as a branch circuit over current
protector and compliant with the national code and requirements. Grounding connection: ≤ 10 Ω.
• 6v DC input - powered by 4 x 1.5v D-size alkaline batteries (not supplied).
Does not require a mains electricity supply.
*Straight-line filtration systems
*For other filtration system configurations,
contact your local Netafim™ representative.
**Filled with sand and water
Concrete slab construction
The sand filtration system will weigh anywhere
from 250 kg up to a few tons. Planning the system
foundation must include consideration of the total
weight of the system when filled with sand and
water.
The media filtration system should be installed
on a concrete slab, at least 4” thick, with proper
reinforcement and anchored to the ground.
The dimensions given in the table on the right are
the external filtration system dimensions and not the
concrete slab dimensions.
The minimum slab dimensions should allow a
sufficient margin around the filtration system for
service and maintenance.
The slab should have a slight grade to allow for water
run-off, but not so steep that the manifold does not
bolt together easily.
The soil all around the slab should be compacted to
prevent erosion.
NOTE
If the filtration system was not ordered with a BackFlush controller and is intended to be connected
to an existing irrigation system controller, see the irrigation controller user manual for instructions.
