LOCATION AND INSTALLATION
Proper planning is an important consideration when installing your new spa / hot tub.
Site selection is a critical step and requires serious thought. Planning ahead makes the
installation process easier. The following information is provided to assist you in site
preparations.
1. Always comply with local building codes and obtain any necessary permits. You
may also need to consult with an engineer to address your specific design
needs.
2. Contact an electrician to assess your electrical needs, install wiring, and assure
a safe operation.
3. Position your spa / hot tub with proper access to water, drainage, and electricity.
4. Place your spa / hot tub on a uniform solid, flat surface designed to properly
support its weight. For external installations, a 4-inch (10 cm) thick cement pad
suffices.
5. For internal installations, check the load carrying capabilities of the floor on
which the spa will reside. Most homes meet the requirement of 250 pounds per
square foot.
6. Assure that your spa / hot tub will fit into the space you have chosen and the
delivery route will accommodate its large size.
7. Provide adequate ventilation for the humidity created by your spa / hot tub. In
most cases, the Color Coordinated Cover is sufficient.
8. Protect the pump and all equipment from the weather by ensuring the cabinet
panels are secure at all times.
9. Allow 36 inches (1 meter) of unobstructed access to all sides of your spa / hot
tub for normal servicing. Your spa / hot tub is not designed to be recessed in the
ground or in a deck.
10.Consider positioning your spa / hot tub out
of or adequately protecting it from the wind.
Just as people can get cold on cool / windy
days so can your spa / hot tub. Windy
environments can significantly increase
operating costs.
11.Consider using an insulating pad. In cold
climates, the ground can rob heat from the
spa / hot tub and increase your operating
costs. Consider using a suitable, outdoor
insulating pad in such environments.

ELECTRICAL SPECIFICATIONS
Important: Qualified and licensed electricians must perform all electrical hookups.
The following specifications must be followed in order to ensure proper performance
and safety.
Starting an incorrectly wired spa / hot tub could cause severe damage
to the mechanical equipment or even bodily harm. Have your licensed
electrician verify GFCI wiring with the schematics on pages 13-14 prior to
starting the spa / hot tub or call your local dealer.
Failure to abide by specifications listed may result in damage to
the equipment and will void the warranty.
Test the GFCI before each use of the spa / hot tub.
* Use only solid copper wire.
WARNING
CAUTION
All spa / hot tubs must be wired with a GFCI breaker (or according to IEEE wire
regulations for export models). Failure to do so will cause equipment damage and will
not be covered under your guarantee. All spa / hot tubs must be protected with an over

For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
Parts with extra low voltage (not exceeding 12V) must be inaccessible to a person in
the spa / hot tub. Earthed appliances must be permanently connected to fixed wiring.
Parts incorporating electrical components must be located or fixed so that they
cannot fall into the spa / hot tub. Means for disconnection must be used with fixed
wiring configurations in accordance with local wiring rules.
IMPORTANT: To allow the GFCI to function properly, connect the white Neutral wire
from the spa / hot tub to the Neutral terminal on the GFCI breaker, not the Neutral bus
bar in the GFCI breaker box. An improperly connected Neutral causes the GFCI
breaker to trip.

the instructions in this manual.

16
For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
Before adding water, go through these simple steps now to prevent common issues
when setting up your spa / hot tub for the first time. Verify that the following have all
been rechecked.
1. Turn off all power at the main breaker panel.
2. Open the front panel to access the internal components.
3. Check that all gate valves are opened to the heater and
all pumps.
4. Check that there are no obvious signs of loose wires or
broken pipes.
5. Check that the two heater unions are tight.
6. Check that the unions on all pumps are tight.
7. Clean out any foreign debris from within the service access area or inside of the
spa / hot tub itself.
8. With the drain open and filters removed, thoroughly rinse out the spa / hot tub with
warm water until the drained water runs clear. Run water through the filtration
canister and jet lines to remove any incidental dust, dirt, and debris that may have
accumulated during shipment or installation. Drain all water completely.
9. Make sure that the spa / hot tub drain valve is closed and the cap is on tight.
10.Install the filters in the filtration canister.
11.Check that all of the jets are open (turned full counter-clockwise).
12.Now is the best time to clean and polish the surfaces of your spa.
CAUTION:
Do not use a wrench.
Over-tightening may cause
damage to unions and gaskets,
which will not be covered the
Guarantee.

For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
Now it's time to fill your spa / hot tub with water. Do not turn
on the electricity until the spa / hot tub is completely filled.
To properly fill your spa / hot tub:
1. Make sure that the filters (in the filtration canister) are
gently screwed into place. Turn them clockwise until
they stop, being careful not to over-tighten them (this
avoids cracking the filter).
2. Connect a standard garden hose to a faucet with regular
cold tap water (not softened water or hot water). Figure 8 - Filtration Canister
The water from your hot water tank should not be used to fill the
spa / hot tub.
3. Put the pre-filter* on the other end of the hose, point the pre-filter into a suitable
drain, turn on the water, and allow any sediment to be flushed down the drain.
Once the water stream runs clear, turn off the hose.
4. Put the pre-filter (if equipped) into the filtration canister and turn on the hose.
5. Fill slowly. If too much water pressure is used, foaming water can force air into
the pipes and cause startup problems.
* Pre-filters are available at most dealers
Important: To ensure that the pump is properly primed, fill the spa / hot tub through
the filter area only.
6. Fill the spa / hot tub until the water level is about 6” below the top lip of the spa /
hot tub. Do not over fill.
Note: Every person entering a spa / hot tub displaces a given volume of water, so
adjust water level to the number of people regularly using the spa / hot tub.
Turn off the hose and check again for any small leaks.
CAUTION
FILLING YOUR SPA

18
For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
Do not turn on any pump until your spa is properly filled with
water. Running any pump without water in your spa can cause
IMMEDIATE damage, which is not covered by the guarantee!
By now you have rechecked your spa / hot tub mechanical connections and filled it
with water to about 1” above all jets by adding cold tap water through the pre-filter (if
equipped). Turn on power to the spa / hot tub at the main breaker panel and test the
operation of the electrical system. If you encounter a problem, please reference the
troubleshooting guide.
Turn on the breaker and test the operation of the Ground-Fault Circuit Interrupter
(GFCI) breaker by pushing the small button. This should automatically trip the spa / hot
tub circuit breaker. Only if pushing this button successfully trips this circuit breaker
should you reset this breaker and proceed to the initial start up procedure.
If this breaker does not trip, immediately call your electrician.
Do not use your spa / hot tub!
1) Ensure the circuit breaker to the spa / hot tub is off.
2) Rotate all the jets in the spa /hot tub to the fully open position.
3) Ensure that all of the gate valves are open. The gate valve is open when the handle
is fully extended up and clipped in place. Models with 1 pump will include 2 valves and
models with 2 pumps will include 4 valves. Note: a circulation pump (when installed)
will include an additional 2 valves.
4) To prevent the possibility of leakage in the equipment bay, ensure the pump unions
are tight.
5) Close and cap the hose bib. This is used for draining the spa / hot tub.
6) Fill the spa / hot tub until the water level is about 6” below the top lip of the spa / hot
tub. Do not overfill.

DANGER
CAUTION
OPERATIONAL CHECKS

19
For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
If water does not flow from the jets after 2 minutes, turn power off
at the main panel and bleed air from the system. Turn power on
again. Sometimes momentarily turning a pump off/on will prime it.
Only do this four times.
7) Turn on the circuit breaker. Set the desired temperature by using the up or down
keys.
8) Push the jets 1 keypad to turn on the low speed pump. Check to ensure water is
coming from some of the jets. If the water is not flowing out, open the pump union
slightly to release trapped air. Close the union when the pump pushes water out of the
jets. Push the jets 1 keypad and the pump will turn on high speed. Observe closely to
ensure adequate water flow. Push the jets 2 key pad (if equipped) and pump 2 will turn
on high speed. Observe to ensure adequate water flow. If there is no water flow
through the jets, the pumps need to be primed.
9) Re-attach the equipment access panel.
10) Ensure proper water chemistry only after completing the above steps.
11) To conserve energy and ensure your spa / hot tub is ready for use, place the color
coordinated cover securely on the spa.
CAUTION
NOTE:
In order to prevent damage to your pillows caused by the gassing effect of the
chemicals, we do recommend to remove them when the spa is not in use. By
removing them you will extend considerably the life length of your pillows. We
do design ours pillows to be removed easily in order to make sure they will not
remain in the spa when it’s not in use.

20
For HELP, call La-Z-Boy® Spas at 1.800.465.2933.
Note: Perform water quality testing weekly and whenever your water is changed (or
when your spa / hot tub is first filled).
Once your spa / hot tub reaches 95ºF, properly adjust the chemistry of your spa / hot
tub water by testing it with good quality test kits and adjusting levels as needed.
Note: Balancing and sanitization products are not included.
Figure 9 – Typical Test Strip Usage
Important: Total Alkalinity (TA) is the first parameter you should balance when
making routine adjustments to your water.
Once your water temperature reaches 95ºF, test the total alkalinity of your spa / hot tub
water with a good quality test kit. Maintain a total alkalinity level of 80 to 120 ppm.
Total alkalinity is the measure of alkaline buffers in your water. These buffers protect
the water against sudden changes in pH. Total alkalinity is considered the key to water
balance.
When the total alkalinity is too low, add sodium bicarbonate. If the total alkalinity is too
high, you can lower it by using muriatic acid or sodium bisulfate.
Test the pH of your spa water with a good quality test kit. Maintain a pH level of 7.2 to
7.8.
A balanced pH promotes bathing comfort and prevents corrosion, staining, scaling, or
cloudy water.
If the measured pH is too low, add soda ash to the spa water. If the pH is too high, add
sodium bisulfate to the spa water. Follow the directions on the manufacturer’s label
and make small changes. Circulate the water for 20 minutes before retesting.
