Installation
The Zodiac MiniJet (FFMJ) is designed for mounting
vertically in a pool wall slightly above water level, or
horizontally in the pool deck, wall cap, planter, etc.
Preparing for Installation
Determine the mean water level of the pool and the vertical
center line of each MiniJet. If water covers the nozzle the
performance will be affected. Mounting it too high may
interfere with the coping.
Pressure testing is required. Screw the 3/8” plug provided
into the nozzle inlet of the MiniJet housing. This plug is also
used for winterizing so do not discard.
Store the brass jet, the MiniJet cover plate, the 3/8” plug
and the four screws for pool start-up.
Prevent dirt and debris from entering the plumbing lines.
Conduct Pressure Test
WARNING
When pressure testing a system with water, air
is often trapped in the system during the filling
process. This air will compress when the system is
pressurized. Should the system fail, this trapped air
can propel debris at a high speed and cause injury.
Every effort to remove trapped air must be taken,
including opening the bleed valve on the filter and
loosening the pump basket lid on the filter pump
while filling the pump.
WARNING
Trapped air in system can cause filter lid to be
blown off, which can result in death, serious
personal injury, or property damage. Be sure all air
is properly out of system before operating. DO NOT
USE COMPRESSED AIR TO PRESSURE TEST
OR CHECK FOR LEAKS.
WARNING
When pressure testing the system with water, it is
very important to make sure that the pump basket
lid on the filter pump is completely secure.
WARNING
Do not pressure test above 35 PSI. Pressure
testing must be done by a trained pool professional.
Circulation equipment that is not tested properly
can fail, which could result in severe injury or
property damage.
1. Fill the system with water, using care to eliminate
trapped air.
2. Pressurize the system with water to no more than 35
PSI.
3. Close the valve to trap pressurized water in the
system.
4. Observe the system for leaks and/or pressure decay.
5. For technical support, call 800.822.7933.
Installing in a Concrete Beam
1. Lay out the center lines of the MiniJet to coordinate
with the tile pattern.
2. Cut or block out a 6” x 6” notch through the beam.
3. Attach the 1/2” feed pipe to the MiniJet. The pipe must
extend past the back of the beam.
4. Mud the MiniJet in place. Check level, plumb and
center lines during the setting process.
5. If the flange on the MiniJet hinders the placement,
cut it using a hacksaw or jigsaw. Leave at least 1/2”
of flange to serve as a water stop. (See Plumbing the
MiniJet)
Installing in a Deck
1. Attach the 1/2” feed pipe to the MiniJet.
2. Level and anchor the MiniJet. The MiniJet cover plate
can be left on if installation is at finished deck level.
Plumbing the MiniJet
Water flow and pressure control the projection of the water.
As a rule, 4.4 GPM per nozzle will provide adequate water
flow. Refer to data below.
