Before installing this product, read and follow all warning notices and instructions which are included. Failure to follow safety
warnings and instructions can result in severe injury, death, or property damage. Call US: (877) 347-4788 - INT: (407) 886-3939

Separation Tank Installation
1. The Sep 100
D.E. 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 five
(5) feet 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 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 separate from
the tank, 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.
Bypass Valves
If the separation tank is plumbed to return water to waste, a positive shut off valve is NOT recommended in the line from the
separation tank. If the system is operated with such a valve closed, the pressure in the entire system would go abnormally
high and could present a risk of the lid and tank separation. Additionally, running the system with no flow will seriously damage
the equipment through heat build-up.
If the separation tank is plumbed to return water back to the pool, a bypass valve must be used. This valve must be closed when
not backwashing through the separation tank so that the separation tank is not under pressure when in the normal filter mode.
