Section 1.
SEPARATION TANK INSTALLATION
A. GENERAL INFORMATION
1. The separation tank should be mounted on a level concrete slab. Position the tank so that the instructions,
warnings and pressure gauge are visible to the operator. Also, position the
separation tank so that the piping connections, control valve and drain port
are convenient and accessible for servicing and winterizing.
2. Separation tanks are designed to work primarily with diatomaceous earth
(D.E.) swimming pool or spa filters. Their purpose is to separate the D.E. and
dirt from filter effluent during the backwash cycle. The separation process
should produce water out of the separation tank suitable for return back to
the pool or disposal into city storm drain systems. The separation process
uses a large cloth "filter" bag to literally filter out the D.E. and its entrapped
dirt particles. During backwashing of a D.E. filter, a valve is used to reverse
the normal flow through the filter. The reverse flow dislodges the D.E. cake
from the filter and flushes it into the top of the filter bag. The D.E. and dirt are captured in the bag and clean
water passes through and exits from the tank bottom (outlet). After backwashing the filter, the separation tank
needs to be opened and the bag cleaned before another backwashing cycle.
3. Install electrical controls (e.g., on/off switches, timers control systems, etc.) at least 1.5 meter from the tank,
with enough room to stand clear of the tank during system start up.
4. Provide sufficient clearance around the tank to permit visual verification that the clamp is properly installed,
see Figure 1.
5. Provide sufficient space above the filter to remove the filter lid for cleaning and servicing.
Risk of electrical shock or electrocution. Position the separation tank and High Flow™ manual air relief
valve to safely direct water drainage and purged air or water. Water discharged from an improperly
positioned tank or valve can create an electrical hazard that can cause severe personal injury as well as
damage property.
6. When installing the High Flow™ manual air relief valve use the O-ring only, there is no need for thread sealing
compounds. Position the filter to safely direct water drainage. Rotate the valve to safely direct purged air or
water. Water discharged from an improperly positioned filter or valve can create an electrical hazard as well as
damage property.
7. Make all plumbing connections in accordance with local plumbing and building codes. Plumbing connections
are provided with an O-ring seal. Use only a silicone base lubricant on the O-rings. Do not use pipe joint
compound, glue or solvent on the bulkhead connections.
8. The base of the separation tank is provided with four (4) mounting bosses for the purpose of anchoring the
tank to the concrete.
9. The maximum working pressure of the separation tank is 50 psi. Never subject the separation tank to
pressure in excess of this amount, even when conducting hydrostatic pressure tests. Pressures above 50 psi
can cause the lid to be blown off, which can result in severe injury, death or property damage.
When performing hydrostatic pressure tests or when testing for external leaks of the completed filtration and
plumbing system, ensure that the Maximum Pressure that the filtration system will be subjected to DOES NOT
EXCEED THE MAXIMUM WORKING PRESSURE OF ANY OF THE COMPONENTS CONTAINED WITHIN
THE SYSTEM. In most cases, the maximum pressure will be stated on each component of the system.
If doubt exists as to the pressure to which the system will be subjected, install an ASME approved automatic
Pressure Relief or Pressure Regulator in the circulation system for the lowest working pressure of any of the
components in the system.
