Complete these steps to install each 112477 insert:
1. Add one FALB34B nut to threaded stud of each
113030S01 foot and attach one foot to each
112477 insert.

hammer if needed to seat in place.
3. Secure each insert to each tube using two (2)
112838 Tek screws. Install screws through leg
tube and wall of the 112477 insert and not the
open side of the insert. Install screws slightly
off center line of the leg tube to prevent contact
with threaded rod.
4. Adjust 113030S01 leveler so it is seated against
threaded plate of insert and locknut. See diagram
to the right.
5. Secure leg tubes to the FT15G16L09000S1 tubes using the 112772 flat head bolts.

the bottom is facing up.
2. At one end of the tray, locate the flat area with dimples that identify
hole locations.
3. Using a 1-3/8" hole saw bit and a drill, carefully drill the bulkhead
holes through the bottom of the propagation tray.
4. Clean debris from the tray and around the holes.
5. Continue with the installation of the bulkhead fittings.

Install Bulkhead Fittings
INSTALL BULKHEAD FITTINGS
System is equipped with two (2) 111301 bulkhead fittings which are used to connect the tray to the lower reservoir.
Gather these parts and install the fittings:

1. Flip tray over so inside is facing
up and center tray on frame.
2. Take one 111301 bulkhead fitting
and verify that the fitting includes
a washer.
3. Insert the fitting with washer
through one of the holes.
4. Seat fitting tightly in the hole.

5. Take the bulkhead nut and turn it
onto the threaded shaft. Tighten
until fitting is snug.
NOTE: Use a large pair of
adjustable pliers if necessary. Do
not overtighten the nut!
6. Repeat the steps to install the
remaining bulkhead fitting.
NOTE: Check both fitting nuts to
ensure each is tight.

ensure that a washer is present
on the inside between each fitting
and the tray.

Prepare Reservoir Lid
PREPARE RESERVOIR LID
Complete these steps to drill the holes in the propagation tray.
1. With assistance, carefully place the reservoir lid on supports for
drilling. Do not drill the lid over the reservoir. Debris can damage the
pump and contaminate the nutrient solution when reservoir is filled.
2. Drill the first hole using a 1-3/8" hole saw bit. This hole is for the 3/4"
tube from the pump. Hole size allows both the tube and the power
cord from the pump to pass through it. See next page for details.
3. Drill the second hole using a 1-1/8" hole saw bit. This hole is for the
3/4" drain tube from the propagation tray.
NOTE: Hole can be drilled using the 1-3/8" hole saw bit if it is the only
bit available. Smaller hole protects the nutrient solution from light and
debris.
4. Clean debris from the lid and place the lid on the reservoir. Slide the
reservoir under the frame and propagation tray.
5. Continue with the next procedure.

1. Set pump in the reservoir.
Measure from pump fitting to
bulkhead fitting. Unwrap power
cord.
NOTE: Pump fitting and o-ring
are included with the pump.
Install these before next step.
2. Cut a tube to the length
measured in Step 1.
3. Take the tube and check the fit
by sliding it onto the pump and
bulkhead.
Cut length if needed to ensure
that hose is not too long. Pump
must rest on bottom of reservoir.
4. Pull lid into place on reservoir
and center reservoir under the
frame and tray. Reach through
port hole and slide end of power
cord up through one hole in
reservoir lid.

5. Pull cord through hole and place
it on top of the lid away from the
port hole.
6. Take the pump hose from Step
2 and slide end though the hole
where the power cord is.
7. Reach through the port hole and
slide a 111698 ratchet clamp onto
the end of the tube.
8. Slide tube onto the pump fitting.
Ensure tube is seated tightly on
the pump fitting.

9. Using a large pliers, gently
squeeze the clamp to secure the
connection. Clamp will click when
tightened. Do not overtighten.
10. Slide another ratchet clamp onto
the pump tube.
11. Connect the tube to the bulkhead
fitting of the tray. Seat tightly on
the fitting.
12. Squeeze clamp to secure
connection.
13. Measure distance between
reservoir lid and remaining
bulkhead fitting. Add a few inches
to measurement so tube extends
through lid when attached to
fitting. Tube can be trimmed later
if too long.
Tube should remain above
nutrient level.
14. Slide a ratchet clamp onto the
tube and slide drain tube through
the hole.
15. Connect tube to the remaining
bulkhead fitting and secure as
previously described.
16. Check all fittings and clamps to
ensure they are secure.
17. System is ready to use. Add
water to cover pump and activate
pump. Check fittings for leaks.
18. Turn pump off to check
for proper drainage of the
propagation tray.

Adjust levelers so tray slopes
slightly toward the drain end.
Adjust levelers so tray is level side-
to-side. Check with a level.
Use the lower photos to determine how to set the slope of the frame. After adjusting each leveler as
needed, use photos 1-4 to lock the leveler in place. A 9/16" wrench is needed.

Install Bulkhead Screen and Extensions
INSTALL BULKHEAD SCREENS AND EXTENSIONS
Photo above shows the bulkhead screens and extensions installed in
both bulkheads.
Photo above shows the bulkhead screen and extension installed in one
bulkhead. A screen without the extension is installed in the other.
111303 111302
Bulkhead screens and extensions allow you to manage the nutrient solution level in the
propagation tray. Screens can be used with or without the extensions. Depending on the
application, extensions can be used with one screen on the drain tube to increase and maintain
the level of the nutrient solution in the tray. A screen installed on the pump tube deflects water
to ensure an even, steady flow. Install these items as needed to achieve the desired results.
Hand-tighten only during installation.
