Section 3. Installation Instructions

Use equipment only in a pool or spa installation.
Do not connect system to an unregulated city water
system or other external source of pressurized
water producing pressures greater than 35 psi.

3.1 Filter Location

Select a well-drained area, one that does not flood
when it rains. Damp, non-ventilated areas should
be avoided.
Provide solid mounting for the filter and pump
system. Install system on a concrete slab or solid
concrete blocks to avoid risk of settlement. Do not
use sand to level the filter as the sand will wash
away. Filter systems can weigh up to 1100 lbs.
Install electrical controls at least 5 ft. from the
filter. This will allow enough room to stand away
from the filter during start-up.
Allow sufficient clearance around the filter. See
Figure 2.
Allow sufficient space above the filter to remove
the filter lid and filter internal parts for cleaning
and servicing.
Position the filter to safely direct water drainage
and to provide for clear access to drain for sand
removal. Align the air release valve to safely direct
purged air or water.
Water discharged from an improperly positioned
filter or valve can create an electrical hazard
which can cause death, serious injury or property
Maintain your pressure gauge in good work ing
order. The pressure gauge is the primary indicator
of how the filter is operating.

Filter Location
JS Series Sidemount Sand Filters
If the filter needs to be located above the water
level of the pool, it can be raised 2.5 ft. without
affecting the pump efficiency. A check valve is
recommended on the suction line to the pump.
If the filter is to be installed below the water level
of the pool, isolation valves should be installed on
both the suction and return lines to prevent back
flow of pool water during any routine servicing
that may be required.
3.2 Anchoring the Filter to the Equipment
In some areas, for example Florida, building
codes require that all appliances be securely fastened
to the equipment pad in order to withstand high wind
pressures created by hurricanes. Please follow all local
codes and standards.
NOTE Anchor screws and washers for securing the
filter to the equipment pad are not included with
the filter. Zodiac Pool Systems, Inc. ("Zodiac")
recommends that a 2¼" X ¼" long stainless
steel Tapcon
concrete screw and stainless steel
flat washer are used to mount each of the four
(4) anchor holes in the base to the equipment
pad. The Tapcon concrete screw meets Florida
building code requirements.
After placing the filter on the equipment pad, as
outlined in Section 3.1, drill a 5/32" hole in the concrete
at each of the four (4) holes in the base of the filter. (The
correct size concrete drill bit should be obtained when
the concrete screws are purchased.)
Install the Tapcon screws and washers through
each of the four (4) holes to secure the filter to the
equipment pad. See Figure 3. Do not over-torque the

3.3 Filter Preparation

Check carton for damage due to rough handling
in shipment. If carton or any filter components are
damaged, notify carrier immediately.
Carefully remove the accessory package.
