• Locate the threaded boss on the outlet port of the
header, and fi nd the dimple at the center. See
Figure
16.
• Use the dimple to center the drill bit.
• Drill a 9.5 mm (3/8”) diameter hole through the
boss.
• Take care not to damage the surrounding plastic
threads. Drilling a 3 mm (1/8”) diameter hole fi rst
will help prevent thread damage.
• Install a 19 mm (3/4”) threaded nipple, elbow and
the pressure relief valve. Make sure to get a sung
fi t. Do not overtighten.
CAUTION
In order to prevent damage, do not tighten with a
wrench. Hand tighten only and use caution not to over-
tighten. Overtightening may crack the header.

only
on threads mating brass
components to the plastic reducer fi tting. Do not use
any pipe compound or pipe dope on the threads or
any part(s) that come(s) into contact with plastic. These
compounds can damage plastic components over time.
Discharge piping must be open with no reducers, or shut-

Chemicals
The IXI heater is manufactured with materials that are
not compatible with high concentrations of ozone,
chlorine, bromine, or other sanitizing chemicals.
Heater damage caused by improper water chemistry
or plumbing configurations are not covered by the
AstralPool warranty. All questions should be directed
to technical support at 1300 186 875. Additional

Be sure to adhere to the following:
• All sanitation equipment is to be installed as the
last piece of equipment in the circulation system.
• When ozone is used, install a mixing degas
chamber, to prevent ozone and air from entering
the heater.
• When chemical feeders are used, install an in-line
check valve between the heater and the feeder.
• Wire any electrical sanitation equipment so that it
cannot operate unless the filter pump is running.
• Always follow pool chemical manufacturer’s
instructions when adding chemicals to pool.
