Introduction
This guide was developed to help you enjoy a trouble-free spa. The information and instructions it presents
are easy to understand and apply to most types of installations. It explains how to maintain an adequate
level of chlorine and how to prevent problems. It also covers all procedures related to the care of your spa,
from opening to closing, including water testing and regular maintenance. At the end of the manual is a
Troubleshooting Guide to help you resolve problems. Of course, the experts at your nearest TRÉVI location are
available to answer any questions not covered by this manual. Refer to this guide to make the most of your
spa. Remember that for your safety, certain precautions must be taken when handling and storing chemicals.
Please be sure to read the warnings and dosage requirements on product labels and to follow package
directions carefully. Never put two chemicals in the water at the same time. Always dilute products in water
before pouring them into the pool. Don’t forget that chlorine is corrosive to steel. And most importantly, keep
all pool products out of the reach of children.
CAUTION : When using chlorine, always add the product to water. Do not pour water over chlorine or an
explosive reaction may result. A few drops of water are enough to trigger an explosion.
Safety precautions
▪To avoid health hazards, never heat the spa water above 104°F (40°C). Limit the use of the spa to
15-minute intervals to avoid nausea.
▪Never enter the spa when under the influence of alcohol or when using drugs that may cause
drowsiness. If you are taking medication, check with your doctor before using the spa.
▪Because children are sensitive to high temperatures, they should use the spa with prudence
▪and only under adult supervision.
▪Pregnant women should consult their physician before using the spa.
▪Hot water is an ideal medium for spreading infections. Do not use the spa if you have an open wound.
▪Always be careful when entering and exiting the spa.
Emergency preparedness
▪Always have a well-stocked First Aid kit on hand in a well-identified place that is easily accessible to
adults but out of reach of children.
▪Keep a sheet outlining cardiopulmonary resuscitation (CPR) procedures near the spa. Make sure the
sheet is waterproof.
▪Encourage each member of your family to learn CPR.
▪Memorize emergency phone numbers.
Insurance
▪Check with your insurance company to ensure that your spa is covered by your homeowner’s policy

Choosing the best location for your spa
Here are some basic elements you will have to remember when choosing the location of your new spa.
Safety first
Do not install your spa within 3 metres of overhead electrical lines.
How will you use your spa?
How you plan to use your spa will help you determine its location. For example, are you going to use it for
recreational or therapeutic purposes? If your spa is mainly used for the family, please allow enough space
around it for activities. If you intend to use it for relaxation and therapy, you probably want to create a
special atmosphere all around the spa.
Environment
If you intend using your spa during the winter season, it is advisable to place the spa close to an entrance
door to your property. By doing this, you’ll have a place to change in total comfort. During the winter,
bare trees don’t really provide any privacy. Take into account the environment of the spa all year round to
establish the best privacy solutions.
Also, think of the view you’ll have when you use your spa. Is your yard equipped with a special landscaped
area that you especially enjoy? Perhaps there’s a special place that boasts a soothing breeze during the day
or a beautiful sunset in the evening?
Prévoyez un accès pour l'entretien
Many people choose to build a decorative structure all around their spa. If you are installing your spa with
any type of structure on the outside, such as a gazebo, remember to allow access for maintenance. The spa
must have clear spaces of at least 18'' each around it to allow the technician to make repairs if need be.
In addition, it is vital that the control panel be made accessible at all times for the technician in
case of breakage.
During delivery
What is not included:
▪Delivery inside the residence.
▪Delivery if access is less than 100" high and 40" wide.
▪Rock dust.
▪Picking up earth and sod.
▪The electrical connection.
▪Installation of the GFCI (switch /circuit breaker compulsory grounding).
▪Installation of the cover, its supports and fasteners.
▪Installation of the steps.

6Trevi Spa User Guidea
After-sale client responsibility
▪Contact the insurer to determine if the spa is well insured for damages which are not covered by the Trevi
warranty. See the exclusions set forth in your general Trevi warranty.
▪Determine the exact location of the spa before arrival of the deliverymen.
▪Provide adequate access for installers, namely 100" high and 40" wide minimum.
▪Contact a licensed electrician for the electrical connection. IMPORTANT: Please notify your
electrician that the 3/6 wire must be copper.
▪Be sure to leave free access all around the spa (on 4 sides) for: service, closing, opening, maintenance
or future repairs (compulsory minimum 18" clearance on each side). It is also compulsory to provide the
same access if the spa is flush-mounted or embedded. If the spa is moved to access it, this will be at the
customer’s cost. Make sure that all screws of the spa are accessible at all times.
▪Fill the spa and add cleaning products.
▪Install the gazebo unless its installation is included in the contract.
▪When the spa is completed and running, take a 500 ml water sample to the store for complete analysis
of your water.
▪Take the free in-store courses for the opening, maintenance and closing of your spa. Only the
maintenance course is COMPULSORY.
▪Following delivery of the spa, you have 3 days to make sure the jets are working well.
Installation options for your spa
Option 1: Installation on stone dust
Remove sod and excavate site to a depth of four inches. The perimeter of the site should allow for an
additional six inches on all sides of the spa (be sure to base calculations on the exact dimensions of your
spa). Fill site with six inches of compacted stone dust, i.e. to two inches above the ground level. You will
avoid that the spa cave in too much into the ground over time and the technician will be able to remove the
spa skirt if a repair must be made.
Option 2: Installation on a concrete slab
Remove sod and excavate site to a depth of six inches. The perimeter of the site should allow for an
additional six inches on all sides of the spa (be sure to base calculations on the exact dimensions of your
spa). Fill site with six inches of washed 3/4" clean gravel, then pour a four-inch concrete slab over gravel
layer.
NOTE: Ensure proper drainage of any water that may accumulate on the concrete slab.
Option 3: Installation on a wood or cement deck
Excavate holes for the installation of 8-inch cement pillars (sonotubes). Footing holes for the pillars must
extend below the frost line. Install pillars under the four corners and center of the spa. Set supports on
pillars and place 2"X 8" joists on supports at 12" intervals. Your deck needs to be able to support 85 lbs per
square foot.

Trevi Spa User Guide 7
Option 4: In-deck installation
Follow instructions for option 1 above (Installation on stone dust) and build patio around installation. Ensure
that the spa remains accessible. Do not let surface deck elements, such as planks, touch the spa. Be sure
to maintain a minimum clearance of 18” all around the spa. It must be accessible for servicing if required.
Option 5 : Indoor installation
It is important to call on the expertise of a building specialist for this type of installation. Indoor installations
must comply with specific criteria, failing which serious problems may arise. Don’t hesitate to call a building
specialist who will be able to guide you in your project.
Option 6 : Installation in gazebo
Be sure to maintain a minimum clearance of 18” all around the spa. It must be accessible for servicing if
required.
Electrical hook-up
All spas must be equipped with mechanical grounding (a no. 6 AWG connector), a 3/6 gauge wire
(MUST ABSOLUTELY BE A COPPER WIRE) and a ground fault interrupter (GFI) / ground fault circuit
interrupter (GFCI) with neutral 120/240 V voltage. The GFI must be installed 5 to 10 feet from the spa for
easy maintenance.
Initial start-up procedures
Step 1: Start-up and emptying the spa
▪Fill the spa by inserting the hose into the skimmer, where the holes are under the cartridges, up to one
inch below the neck jets (at the level of the trapezoids) or one centimeter below the lowest pad. All
cushions must be outside the water.
▪Fill the spa with the skimmer by removing the filters and filling to 1/4" below the lowest headrest.
▪Put the GFCI to ON and activate the pumps.
▪Put 2 cups of bleach directly into the tub and let agitate for an hour. Attention: the pumps will turn off
after 20 minutes, so do not forget to re-start them.
▪Put the GFCI to OFF.
▪Drain the spa according to one of the following methods:
- Using gravity, with the help of the drain hose: pull the drain plug and, once released, unscrew it.
Screw on the hose and pull the part forward again so that the water drains.
- Using gravity, with the help of a vacuum cleaner hose.
- With a submersible pump.
▪Clean the spa shell with a cloth and mild soap (ideally dishwasher detergent because it won't make much
foam). Rinse well.
▪Fill up the spa.
▪Bring a 500 ml sample of the spa water once the water temperature has reached over 85°F (30°C) to your
Trevi store to analyze the water.

Winterizing procedure
Note: Carefully read this entire document before proceeding with the closure of your spa.
In order to avoid unpleasant surprises, please check with your insurance company to make sure that your spa
is insured. If you choose not to make optimum use of your spa and prefer closing it for the winter, we suggest
that you continue to maintain it until the time of closure and have a complete test of your water done in one
of our two superstores or six branches. Keeping the water clean longer helps minimize the accumulation of
dirt and the formation of bacteria, thereby preventing any risk of contamination. To protect equipment against
freezing and to maintain clear water, never turn off the filter system prior to winterizing the spa.
Step 1: Procedure
▪First, run pumps and pour 2 cups of bleach into the spa, let the pumps run for one hour. (Warning: pumps
will shut off automatically after 20 minutes, so don’t forget to restart them periodically).
▪Disconnect the power supply to the pumps, the lights and the ozone generator.
▪Empty the spa using one of the following methods:

▪Remove cartridge(s) and rinse with clean running water. Let them soak in Cartridge cleaner for
12 hours, as per the product’s instructions. Rinse, air dry and store for the winter. If the cartridges are no
longer any good, make sure to note all relevant information (such as model number) and photograph the
cartridges before discarding them.
▪Remove all adjustable jets Leave headrests in place.
▪Clean the shell with a mild soap, such as liquid dishwashing soap.
▪Make sure that the guillotine valves are open (located on either side of the heating element as well as
in front of the pump(s). If your system is equipped with In.Clear, refer to section Cleaning your in.clear
below
Step 2: Draining the pipes
You should use a Shop-Vac type vacuum with 4.5 HP blower or more to shut down your spa properly.
Scenario 1: Spa with one bypass valve for each pump:
▪Step 1 (Begin with pump 1) – Unscrew the bypass valve by 2" and remove all o-rings to avoid losing them.
Remove the black swivel inside the valve, and blow into the centre with the blower. Insert the swivel
backwards and direct it towards the left or right opening. Make sure you do this for both valves. Reinstall
the o-rings, taking care to lubricate with Jack’s formula and replace pivot correctly to close valve.
Vacuum the remaining water from the footwell.
▪Repeat step 1 for pump # 2 (and pump # 3, if applicable)
▪Step 2 (secondary pipes) – Neck jet and waterfall valves. Unscrew the on/off valve, remove the o-rings
and the swivel. Blow into the valve using the blower cone until no water is left in waterfalls and neck
jets. Reinstall the o-rings, taking care to lubricate with Jack’s formula, and reinstall the swivel properly.
Close the valve. Vacuum the remaining water from the footwell.
▪Step 3 –Vacuum the spa’s drain for about 1 or 2 minutes with the vacuum cleaner. Vacuum each body jet
at least twice using vacuum. Vacuum the ozone generator nozzle using the vacuum cleaner, as well as
the holes in the skimmer and bottom drains.
▪Dry any residual traces of water on the spa shell with a chamois.
Scenario 2: Spa with 1 bypass valve for 2 pumps, or no bypass valve at all.
NOTE: If the spa is not equipped with a bypass valve, begin at step 2 and repeat step 2
for pump 1 as well.
▪Step 1 (Begin with pump 1) – Unscrew the bypass valve by 2" and remove all o-rings to avoid losing them.
Remove the black swivel inside the valve, and blow into the centre with the blower. Insert the swivel
backwards and direct it towards the left or right opening. Make sure you do this for both valves. Reinstall
the o-rings, taking care to lubricate with Jack’s formula and replace pivot correctly to close valve.
Vacuum the remaining water from the footwell.
▪Step 2: Remove the skirt on the side where pump 2 is located. Unscrew the two rings from pump 2. It is
sometimes necessary to remove the pump entirely from its position. Be careful not to break anything on or
around the pump when removing it. Blow into the front tube to clear the drains properly. Blow into the top
pipe to thoroughly flush the jets. You should do this at least twice for each pipe. Vacuum the remaining
water from the footwell.
▪Step 3 (secondary pipes) – Neck jet and waterfall valves. Unscrew the on/off valve, remove the o-rings
and the swivel. Blow into the valve using the blower cone until no water is left in waterfalls and neck
jets. Reinstall the o-rings, taking care to lubricate with Jack’s formula, and reinstall the swivel properly.

Opening procedures for spas
Preparation
If you followed our advice when you closed your spa, opening procedures will be very simple for you!
▪Check the general condition of your spa for the following problems: split hoses, broken valves; loose
collars or clamps; dried up seals; cracked acrylic, etc.
▪Make the necessary repairs before continuing. If necessary, do not hesitate to go to your TREVI store.
▪Check the chemicals you have in stock. If they are outdated, throw them out. If you are missing any,
procure them before continuing with the opening. If you have an Aqua check or Trévi 3-IN-1 TEST KIT,
check the expiration date.
Step 1: Preparation of spa
▪Make sure the spa is level.
▪Remove wooden cover installed when winterizing.
▪Remove cover and clean with the Cleaner for spa cover or 1 teaspoon of liquid dish soap to 9 liters of
water. Rince thoroughly.
▪Place filtering cartridges and basket in skimmer.
▪Connect motor, blower and ozonator (if applicable) and light.
▪Open ball valves on the pipe ends.
▪Clean the acrylic using slightly soapy water.
▪Replace jets in their housings.
▪Fill the spa with a garden hose up to 1 cm below the lowest cushion.
▪Place the garden hose towards the hole(s) of the cartridge(s).
▪Put the GFCI to « ON ».
▪Close air controls and jets.
▪Operate the 2 pumps and add 250 ml of TREVINERGY WHIRL. Leach for 1 hour.
▪Drain the spa using the drain plug.
▪Fill the spa with a garden hose up to 1 cm below the lowest cushion.
▪Place the garden hose towards the hole(s) for the cartridge(s).
▪Put the GFCI to « ON ».
▪Adjust the desired temperature on the keyboard.
Step 2: Water treatment
▪Balance alkalinity. It should be between 80 and 100 ppm, ideally 100 ppm. Chlorine and bromine tablets
have a tendency to gradually reduce alkalinity. When total alkalinity is low, pH is unstable, water becomes
corrosive and disinfectants do not work. To increase total alkalinity, add TREVINERGY ALKA. To reduce
it, add ph-
▪Balance pH. The spa water should be slightly alkalic, i.e. between 7.2 and 7.6.
▪Add 5 caps of TREVINERGY CLEAR. Wait 1 hour.

Trevi Spa User Guide 13
▪Add 5 caps of TREVINERGY SECURE. Wait 1 hour.
▪Begin disinfecting the water with your usual sanitizer.
Precautions when using your spa during winter
So you’ve decided to take advantage of your spa year-round? Here are a few precautions you should take to
avoid damage that may be caused by frost or power outages.
▪Check with your insurance company to ensure that your spa is covered by your homeowner’s policy.
▪Increase your filtration cycle (FD : 02 - FF : 04) to 8 hours of filtration daily.
▪Have two 15A ceramic heaters handy, in the event a mechanical breakdown occurs. It is important
not to connect the two heaters onto the same electrical outlet. If you only have one outlet
outside, you will need to use an extension cord and plug the other heater inside the property.
▪Always have 4 (four) gallons of non toxic antifreeze Permafrost on hand in case a power failure forces
you to shut down your spa.
▪Even in cold weather, you should always treat your water to avoid contamination.
▪Remove the snow from your spa cover on a regular basis : it can only support a maximum
▪weight of 100 lb.
▪If you plan on being away for an extended period of time, make sure there is someone to take care of your
spa and that this person knows what to do if the spa breaks or if there is a power failure. Otherwise, shut
down your spa before leaving.
▪Change the water in your spa one last time before frost sets in, in order to perform the operation as safely
as possible. Clean all of your spa’s components thoroughly; this way, you will start the winter with clean
water which will make maintenance easier, as water cannot be changed in winter due to the risk of frost.
▪Have a specialist perform a full analysis of your water quality in order to start the winter season with
ideal conditions and check your spa daily.
▪Should you require any assistance, our service department will be open all winter. Here is the phone
number to reach us : (514)22-TREVI (87384).
Draining procedures
Because your spa holds a relatively small amount of water, contaminants such as body oil, perspiration, dirt,
hair, etc., may become quite concentrated. For this season, the water should be drained and replaced
every three months depending on use.
▪Step 1: Turn off power at the breaker.
▪Step 2: Pull hose bib out approximately 2" from bottom corner of spa. Remove cap by turning counter
clockwise.
▪Step 3: Hook up a garden hose to the hose bib located on the exterior corner of the cabinet. With hose
still attached to bib, push the bib approximately half way back in. Water should-then start flowing.
▪Step 4: When water begins to drain out of the hose, be sure to drain the water to a convenient place.
▪Step 5: After draining is completed, pull bib back out the full distance. Remove the hose. Replace cap.
Push bib all the way back into corner of spa. Wipe down the inside of your spa making sure your surface
is dry and free from standing water. We recommend that after draining or cleaning your spa that you
put the cover back on. Avoid exposing the acrylic surface to direct sunlight for an extended period of

14 Trevi Spa User Guidea
time. Extended exposure can cause surface fading or cracking, which could void the acrylic warranty.
Note: Be sure that hose is on a downward grade to properly drain spa.
Winter emergency procedure
If you need to temporarily install heaters near your spa to prevent the water from freezing in the piping and
avoid damaging it, here's how:
Step 1: Open the panels on the front of your spa.
Step 2: Arrange the panels at an angle to form a wall on each side.
Step 3: Place the heaters.

Trevi Spa User Guide 15
The left side heater should be directed 45
degrees to the right. The right side heather
should be positioned straight in-line or slightly
oriented towards the right. In this way, the
hose of the water heater will remain hot and
air can circulate everywhere below the spa,
thus avoiding frozen piping. You must raise
the heaters onto blocks or pieces of wood so
that the hot air circulates inside the spa and
not on the black membrane.
Step 4: Protect and insulate the spa
Place a canvas of about 15' x 10' on the spa, then replace the cover. Use the center panel of your spa skirt as a wall to create a
shelter with canvas.
Step 5: Insulate the spa
Next, place snow all around the canvas to insulate and retain heat inside the shelter.

Step 1: Attaching the removal support.
Note: Place the spa cover in the closed position. Offset
the back of the U-bracket for the cover border 5 cm
(2") forward. Make sure the U-bracket is parallel to the
spa cover. (Figure 1.1)
▪Surface installation: Attach the U-bracket on the
top of the frame in the pre-drilled wood holes using
4 1 1/4" bolts. Install the other side the same way.
(Figure 1.2)
▪Side installation: Check that once assembled, the
bracket and the support will have at least 4 aligned
holes and that the support will be at 5 cm (2") from
the edge of the spa.
▪Mark the position of the side bracket holes on
the wooden edge of the spa and attach it using
4 1 ¼" bolts. Install the other side the same way.
(Figure 1.3)
▪Align the holes of the side bracket with the
holes in the U-bracket. There are 5 holes on the
U-support and 6 on the bracket. You must align at
least 4 holes and secure with the 3/4" bolts and
nuts. (Figure 1.3)
Step 2: Assembly of pivoting arms.
▪Screw the stabilizer bar into the small threaded
cylinder on the pivoting arm using a 5/8" bolt so
that the bar passes over the square tube and is
perpendicular to the tube (Figure 2.1).
Note: If the cover is more than 12.5 cm (5") thick,
screw it parallel to the tube or omit it. Partially
screw the extension arm tightening key in the hole
located above the stabilizer bar. (Figure 2.1)
Select the swivel arm with the stabilizer bar
pointing inwards and attach it to the U-bracket using
a hexagonal 1 ¾" bolt and self-locking nut. Do not
overtighten. (Figure 2.2)

Step 3: Cylinder installation
Note : Installez le cylindre hydraulique avec blocage du coté le plus accessible du spa. Le tube de blocage doit être
en bas et sa partie chevauchante doit être du coté du support en U. Sa partie coupée fait face à l'arrière. Fixez le
goujon fileté du petit tube du cylindre hydraulique dans le support en U et sécurisez avec l'écrou indésserrable.
Fixez l'autre bout, le gros tube du cylindre hydraulique, dans le bras pivotant et sécurisez à l'aide d'un autre écrou
indésserrable. (Figure 3)
Step 4: Assembly of the extension arm
▪Place the extension arms on each side of the spa and make sure that the set-back, attached, threaded cylinder is
on the top. Screw the 2 pins into the end of each lower side extension arms. (Figure 4.1) Place the spa cover to the
closed position and pull it forward. Slide the extension arm pins into the center of the cover seam by keeping the
upper pin visible (Figure 4.2). Do the second side. Fold the pivoting arms and push the cover to reinsert the extension
arms until the cover is in its normal position. Check that the extension arms are inserted at an equal distance. Screw
the locking key to maintain the position (Figure 4.3).
Step 5: Removing the cover
▪Fold the front half of the cover and lift the cover to the rear (Figure 5).
Step 6: Removing the cover
▪Push the hydraulic cylinder blocking tube and push the spa cover. Unfold the cover.
