2.2 Plumbing Hook-Up
Backflush discharge pipe should be 2 inches in diameter if line is less than
20 feet long with no more than one elbow; pipe with 2-1/2 inches or 3 inches
in diameter should be used if line is longer and may be manifolded if desired.
Any restrictions in the backflush line will reduce the cleaning ability of the
filter.
The incoming line should have a minimum I in. air vent vacuum relief valve
installed to prevent water hammer. Discharge lines should never run uphill.
This will affect the required pressure differential and reduce cleaning.
Strongly Recommended: A block valve should be installed immediately
upstream of the filter. During start-up, the block valve should only be
barely cracked open to prevent a surge of pressure across the filter
once tne pump is started. Once the pump is on-line, slowly open the
block valve. This would prevent any possible damage to the filter due
to a pressure surge. It is also recommended that a block valve be
installed downstream of the filter which would enable the filter to be
isolated for service.
2.3 Electronic Controller Hook-Up (See drawing on Page I5)
Before power is applied to the electronic controller, make all connections
between controller and solenoid valves.
1. SOLENOID CHECK OUT - using appropriate power source to energize
switch and proceed as follows: put ear close to solenoid, trip switch and
listen for a "click” open and a "click" shut.
2. FLUSHING TIME ADJUSTMENT - the flush time is normally set for five
seconds. For difficult contaminants, it may be increased to six seconds
or longer.
3. PRESSURE DIFFERENTL ADJUSTMENT - the triggering differential is
pre-set for 7 psi. It can be changed to different setpoints (see your rinse
controller manual).
