Step 1 - CHOOSE PROPER PLACEMENT
It is important you carefully consider the placement of your Tank before you
start the installation. Once installation is completed and the Tank has been
filled, relocating the Tank will require transferring and storing 200 gallons
(757 L) of water and Epsom salt solution.
★Choose a preferred location that will stay between 70° and 90°
Fahrenheit (21° to 32° Celsius).
★Allow at least 1 ft (30 cm) of space between the Float Tank and the
room’s walls to allow for maintenance and cleaning.
★Consider the space between the front, door side, of the Float Tank
and the wall to allow for entering and exiting.
1. Interlock the Foam Tiles (#5) in a 3 x 5 configuration
a. You may need to rotate the tiles to align for the proper fit
2. Position the connected Foam Tiles (#5) in the room to the preferred
location
9

Step 2 - PLACE HEATER PADS
The Heating Pads (#4a & #4b) are placed on top of the Foam Tiles (#5),
and will radiate heat up into the water.
IMPORTANT
☆ VERIFY THE PADS ARE THE CORRECT SIDE UP ☆
1. Place Heating Pads ( #4a & #4b) on top of the Foam Tiles (#5):
a. Inside edges of the Pads should touch, but not overlap
2. “This Side Up” sticker identifies proper side is facing up
3. Orient Heating Pads( #4a & #4b) on top of the Foam Tiles (#5) so the
electrical cords face the rear side of the Tank (opposite the Door
Side)
4. Pads will be located toward the rear edge of the foam tiles:
10

5. Temporarily plug the Heating Pads ( #4a & #4b) into the Temperature
Controller (#6), and plug the Temperature Controller into a wall outlet:
a. Plug the two Heating Pads (#4a & #4b) into the Temperature
Controller (#6)
b. There are two available plugs from the Temperature Controller
(#6), and one will have the Grounding Probe (#8) already
pre-plugged into it
c. Either Heating Pad plug can be used for either of the two
available Temperature Controller plugs - operation is not
affected by this selection
● Properly functioning Heating Pads will quickly become hot to
the touch in 4 to 5 zones.
● Do not leave Heating Pads plugged into the wall outlet for more
than 30 seconds without water in the Tank.
● If a Heating Pad does not heat up please contact our support
team before continuing assembly.
6. Unplug Temperature Controller (#6) from the wall outlet
11

Step 3 - PLACE BASE DRIP MAT
1. Unfold and spread out the Base Drip Mat (#2) over the Foam Tiles
(#5) and the Heating Pads (#4a & #4b)
a. Locate the oral air inflation tube on the Drip Mat (#2)
b. Untighten the end cap on the oral air inflation tube
c. Blow into the end cap on the oral air inflation tube until the
surrounding berm of the Drip Mat is fully inflated
d. Retighten the end cap on the oral air inflation tube
2. Position the Base Drip Mat (#2) over the Foam Tiles (#5) and the
Heating Pads (#4a & #4b)
Step 4 - INFLATE & PLACE TANK BODY
There are seven different air valves on the Float Tank Body you will need
to inflate to complete the process:
● Left wall valve #1
● Right wall valve #2
● Rear wall valve #3
● Lower front wall valve #4
● Door frame valve #5
● Door valve #6
● Door Inside Valve #7
1. Attach supplied Air Inflation Pump hose to the Air Inflation Pump on
the inflation side marked “INF” (“DEF” will create a vacuum that
removes air from the panels)
12

2. Move pump selection switch to “SINGLE ACTION” (easier) or
“DOUBLE ACTION” (faster)
3. Remove all air valve protective cap covers
4. Attach the Air Inflation Pump hose end to the air valve with a
clockwise twist
5. Use Air Inflation Pump to inflate each panel to 6 PSI (0.4 BAR)
6. After each wall of the Tank has been inflated make sure you fasten
the valve cap
a. Not doing this might cause air to leak if the valve pin is pushed
down
b. Move the string that connects the air valve protective cap to the
air valve body so it is not trapped under the air valve protective
cap
7. Place the Tank Body (#3) on the Drip Mat (#5) by lining up the Tank
Body over the Heating Pads (#4a & #4b)
8. Allow the Tank to sit for 24 hours as the panels may stretch, check
the panels after 24 hours and add pressure as needed
★TIP: Each valve has a pin in the center that can be manually pushed
down to quickly deflate the walls:
○ If you push down and turn the pin clockwise the airway will stay
open for easy deflation
○ When inflating a panel, check that the pin is in the proper UP
position to hold air
★TIP: This is the perfect time to reconsider the placement of the Tank -
get in and out, and move it around to be sure you’re happy with the
location before you add water and Epsom salt.

Step 5 - INSTALL VENT CAPS
The Vent Caps (#5) are designed to allow fresh air to circulate through the
Tank while helping to block direct light from entering. Installation of the
Vent Caps is optional, but installing two on the inside of the air holes is
recommended (some owners prefer installing two inside and two outside,
but this can lead to condensation gathering outside of the Tank).
1. Insert three of the four tabs on the base of a Vent Cap (#5) into an air
hole on the back inside wall of the Tank
2. Use a finger to tuck the fourth tab into the air hole to secure the Vent
Cap
3. Repeat this process for all Vent Cap installations
14

Step 6 - INSTALL FILTRATION SYSTEM
#15 - Pump Manifold
#7a & #7b - Water Pump & UV
Water Filter
#10 - Filter Bag
#11 - T Fitting
#12 - 90 Degree Fitting
#13 - Water Filtration Hoses
1. Set the Water Pump and UV Water Filter (#7a & #7b) in the
back left corner of the Tank
2. Screw the Pump Manifold (#15) the top of the the Water Pump
(#7a)
15

3. Plug the Filter Bag (#10) into the orange quick connect of the
Pump Manifold (#15)
4. Feed Filter Bag (#10) through loops located on the rear wall to
hold the bag in place
5. Route the plug wires through the neoprene sock to the outside
of the Tank
6. Connect the Water Filtration Hoses (#13) together with the T
Fitting (#11)
7. Fit Filtration Hoses (#13) between the C-clips located on the left
interior wall to securely install them in place
a. C-clips can become twisted during shipping, but can be
gently manipulated to accept the Filtration Hoses (#13)
b. The Filtration Hoses (#13) will be curved and ridged when
you receive and install it but will relax after the water is
added and warmed
16

Step 7 - FILL TANK WITH WATER &
EPSOM SALT
1. Install Inline Carbon Water Filter (#17) to the hose you are using to fill
your Tank
p
2. Run 5 gallons (20 liters) of water through the Inline Carbon Filter
(#17) into a drain or until water runs clear, to make sure no excess
carbon from the Inline Carbon Filter is deposited into the Tank
3. Add 3 inches (7.5 cm) of water to the Tank:
a. Only use non-heated, tap-temperature water
4. Smooth out creases on the tub floor as much as possible
17

5. Continue to fill the Tank with water to 4 inches (10 cm) deep:
a. Hot water can be used at this stage and will help dissolve the
Epsom Salt
b. Stop filling with water when you reach 4 inches (10 cm) deep
6. Add Epsom salt to the water in the Tank:
a. 100 lbs (45 kg) at a time, mixing in fully as you go
b. Standing in the water and mixing it around with your feet can
make the process go quicker
c. TIP: Using a clean sump pump on its side is the fastest way to
mix the Epsom salt into the water
d. As the Epsom salt dissolves the water temperature will lower
due to an exothermic reaction
7. Add and mix all 800 lbs (363 Kg) of Epsom salt into the 4 inches of
water (10 cm):
a. The water level will rise as more Epsom salt is added
8. Continue filling with water level until 9 inches (23 cm) of depth is
reached:
a. Hot water can be used at this stage and will help the Tank
reach the desired temperature more quickly
b. Mix all salt into the water before using the provided Water
Pump (#7a)
NOTE: If you bought your salt from Zen Float Co, you received 800 lbs
(363 kg) of Epsom salt and you will use all of it for the first fill of your Tank.

MAY RESULT IN SERIOUS INJURY OR DEATH.
1. Plug the Temperature Controller (#6), the Water Pump (#7a) and the
UV Water Filter (#7b) ONLY into a GFCI Adapter (#9, if included) or a
built-in GFCI / RCD outlet.
2. Plug the two Heating Pads (#4a & #4b) into the Temperature
Controller (#6)
a. There are two available plugs from the Temperature Controller
(#6), and one will have the Grounding Probe (#8) already
pre-plugged into it
b. Either Heating Pad plug can be used for either of the two
available Temperature Controller plugs - operation is not
affected by this selection
3. Insert the Grounding Probe (#8) into the Tank through the access
port
4. Submerge the Grounding Probe (#8) and insert the tip into the built-in
holder at the left rear of the Tank Interior
5. Insert the Temperature Controller (#6) sensor into the Tank through
the access port
6. Submerge the Temperature Controller (#6) and insert the tip into the
built-in holder at the left rear of the Tank Interior

7. Plug the wall plug from the Temperature Controller (#6) into a GFCI /
RCD protected outlet
8. Plug the UV Water Filter (#7b) plug into a GFCI / RCD protected
outlet
9. Plug the Water Pump (#7b) plug into a GFCI / RCD protected outlet
● Water should now be circulating through the filtration system and a
slight glow should be coming from the UV Water Filter (#7b).
● The Temperature Controller display will now display a temperature
detected by the attached temperature sensor.
● For safety, the Tank’s water should be electrically grounded. Please
contact a licensed electrician if you have any questions or concerns
about your home’s electrical system being properly grounded.
