1.3 Professional Customer Service
Doing your job in a way that keeps cost of service low and pro t margin high also creates customer
satisfaction. That’s being a professional!
1.4 Responding To An Incoming Service Call
1.0 Standard Troubleshooting Approach (S.T.A.)
1.1 Why A Standard Troubleshooting Approach?
Service prices are basically set by local industry and geographic region. Stiff competition in the service
industry has made it dif cult to raise the price of a service contract; or charge more for time and mate-
rials than the competetive shop down the street. If your business is to be pro table, you must control
the overall cost of service. The total cost of service is made up of many individual factors, but three in
particular are more important than the rest combined:
1.
2.
3.
Time of Repair - How long it takes to  nd and  x a problem.
Time Between Failures - How often are you called to repair any one particular hot tub? How many
times are you called back to  x the same problem on the same hot tub?
Parts Usage - Except in rare circumstances, only one part fails. How many parts do you replace
before you  nd the bad one.
The Jacuzzi Premium STA Manual has been designed to help you control the overall cost of service
by focusing on the three important aspects of your job outlined above. The STA will help you  x your
customer’s hot tub quickly,  x it well, and use fewer parts.
1.2 How To Use The STA
The STA was developed by the Jacuzzi Premium Technical Support
Department and is designed to be the communications link between
you and your customers. If you call for help on any symptom covered
in this book, you will be told to do what the STA recommends, there-
fore, you will save time by calling technical support after you have
done what the STA tells you to do.
Be
Prepared!

Phone personnel.
Which staff member(s) takes the initial call? This person is responsible for han-
dling the call, writing up and making sure that the service technician receives all the
information the same day.
Determine the customer complaint.
Determine whether this is a service call or a maintenance issue that can be handled over the
phone.
Saving you (the technician) time and the company money should be a priority.
Verify the model number, serial number and con rm that this is the original owner of the spa.
The original owner is the only one covered under the terms of the warranty.
Know what components are covered under the terms of the warranty, the length of time of the war-
ranty and then con rm that the owner understands what will and won’t be covered in the event of
a service visit.

Question the homeowner to determine, if possible, what speci c component is not functioning.
Use the map of the spa (see below); become familiar with the components and their names. This
will also help when speaking to technical service.
Keep the Owner’s manuals in an accessible place.
Know the difference between the spa’s components and how they perform when utilized in the spa.
Example: An air control will induce air into the plumbing of the jet, increase the  ow of water and
make the jet more powerful.
Ask what is showing on the control panel.
Are there any error messages? Ask the customer to speci cally describe the topside control panel
readout, if any.
Determine if the error message is the result of a safety feature or if a service call needs to be set
up.
“Cool” and/or “Ice” are generally the result of a spa that has just been  lled or re lled and doesn’t
require any action on the part of the homeowner or the technician.
Know how the  ltration system works, what its defaults are, when it comes on and if there are any
automatic times that it will come on during each day. Know the symptoms!
Setting up the appointment.
Make sure you verify the name, address, phone number and where the customer can be reached
if not at home.
Ask if there is access to the spa if the owner is not going to be present.
Ask about anything that may bar your access to the spa such as locked gates, locked electrical
boxes, vicious dogs, etc.

Make Sure there is access to the main breaker and GFCI, and ask the homeowner to disconnect
if possible before you arrive at their home.
Use the home service visit as an opportunity to sell aftermarket items such as chemicals, towels,
etc.
Educate your staff regarding chemicals that are important for optimal use and longevity of the spa
components.
Chemical misuse is not covered under the terms of the warranty.
Know what to recommend when the customer complains that they cannot get their chemicals
properly balanced. This is not a service call covered by the warranty or a problem that involves the
manufacturer.
All spas are used differently: heavy or light bather loads, adults only, the whole family, bromine or
chlorine, etc.
Does the customer know how to properly clean the  lter and that the spa needs to be disabled
when doing so?
Suggest a second  lter to the customer if the original  lter needs to be soaked in a cleaning solu-
tion. Have one in your truck!
Find out what chemicals the customer is using. If they have saturated the spa with different kinds
of chemicals, sometimes it is best to empty the spa and start all over.
BENEFITS YOU WILL RECOGNIZE
•
•
•
•
A satis ed customer is one who will continue to call upon you for business and does
not contact your competitors.
Educating your staff will increase their value and allow you to focus on real service
issues.
Being properly prepared will increase your productivity and permit you to enjoy a
weekend once in a while.
Bottom Line: If you change the way you approach your customer, you’ll be putting
more money in your pocket.

Know what each call is asking of you; determine whether or not the extent of service can be han-
dled with a simple phone call or if it requires a visit.
Determine whether the call is warranty or non warranty. Make sure the customer is aware that the
manufacturer will not cover out-of-warranty service.
If you plan to charge the customer for travel expenses, make sure that they are aware of the costs
before you show up.
Make sure all of your testing devices are functioning properly and extra batteries are on hand.
Always bring a meter; when calling technical support, please ensure that you have all of the
pertinent information, such as the spa’s serial number, model number, the system you are
working on, etc.
Prepare your route so you may complete the maximum number of service calls each day.
A map book or a large map of your service area will greatly increase your ef ciency.
Bring all the tools needed to properly perform service calls.
Always have your vehicle properly stocked with replacement parts.
Have a sump pump available for draining purposes; emptying a spa from the drain line takes a lot
of your time, which we know is extremely valuable.
Properly prepare for the day’s service calls.
When reviewing your calls, think of every possible component and tool that you may need. For
example, if there is a heating problem or the heater doesn’t come on, think of all the components
that include anything to do with a heat call, such as the temperature sensor, circulation pump, main
pump,  ow or pressure switch,  lter, circuit board, heater, etc.
Prepare for the worst possible scenario and plan to be able to satisfy the subsequent problems
that may arise.
Dress appropriately. Although this is one job where shorts are acceptable, to maintain your cred-
ibility as a professional, leave the half shirts and shirts with derogatory or obscene comments at
home.
Finish your cigarette before speaking with the spa owner and remember - no drugs or alcohol!
Be on time for your appointments. If you are going to be late or can’t make the appointment, call
the customer to inform them of what’s happening.
Call your of ce and ask them to call the people on your schedule to tell them you are running
late.
Always support the product that you service.
Do not berate the product in front of the homeowner. It is essential to maintain the integrity
and reputation of the product, and berating the product may affect your credibility as an authorized
service professional.
If you feel there is a problem that needs special attention, call us or complete a quality alert. Re-
member, this is a partnership between you and the manufacturer - we want to provide the best
quality product possible, with your business providing the best service possible!
1.5 Preparing For A Service Call

9
1.6 Before Calling Technical Support
Make sure you have followed the STA and  lled out a “Troubleshooting Data Col-
lection Form” (see example on page 61). Have the STA manual and the Trouble-
shooting Data Worksheet near the telephone. Technical Support can help you
best if these things become the communications tools for the phone call.
1.7 Before Leaving The Customer
Even if you don’t have to  ll out a Troubleshooting Data Collection Form, please do so. If this is a war-
ranty repair, the information will be needed when your of ce  lls out the “Returned Goods/Labor Tag”.
In any case, it will help you spot trouble before it happens. Pumps burn up if voltage at the hot tub is
too low. Circuit breakers trip if heaters and motors draw too much current (Amps). Wires overheat and
connections burn if wire size is too small or push-on connectors are loose. Call backs cause cost of
service to increase!

Make professional repairs.
Putting bondo, underwater epoxy, silicone or any other product to  x cracked or leaking plumbing
will not adequately correct the problem and will most likely result in a return visit. Replace the com-
ponent or come back and do it for free!
Make repairs look as good as or better then when you started.
Make sure you leave the customer’s home as clean as you found it.
Most customers don’t mind if you are having lunch in their backyard, as long as you remove the
evidence! Make sure to pick up any trash that you may have generated through repairs as well as
break times, lunch, etc.
Leave a work order with the customer explaining what you found to be the problem and how you
corrected it.
Make sure the customer understands the work order.
Suggest to the customer any improvements they can make in maintaining their spa.
Recommend replacement  lters or a new cover if there is a need for one. A spa vac is an easy sell
once you demonstrate it to the customer.
Always carry a box of  lters and a box of the basic chemicals; once you have  nished the service,
politely ask if they need any chemicals or a new  lter. Drop off chemicals in a sealed box if they
have ordered them when they made their service appointment.

10
1.8 Satisfying The Customer
Most customers do not care what work you have done or what parts you
have replaced, but they always care whether or not their problem goes away.
When you are done, show them that their problem is gone. If they ask how you
did it, take a few minutes to explain. Show them the bad part(s) and explain or
show why it is bad.
•
•
•
Develop the habit of examining the hot tub’s you service. Compliment customers on the things
they are doing right. Tell them how their care and attention can stop trouble before it starts.
Mention if you noticed any adverse conditions, especially if the hot tub is under warranty or con-
tract, that could lead to failure. Can the customer correct the problem? Would they like you to correct
it? Can you recommend someone? Would they like an estimate?
Think of yourself and the customer as a “team” trying to keep the product up and running as cost-
effective and time-ef cient as possible. That’s good for the customer, and it’s good for your busi-
ness.

2.0 Electro Static Discharge
2.1 ESD - What Is It? What Does It Do?
Static electricity is always being generated around us, even at those times
when we no longer get zapped after walking across a rug and touching some-
thing.
Like all state-of-the-art circuit boards, the hot tub’s circuit board can be dam-
aged by unnoticed static electricity. Damaged is the key word. Sometimes a
board which has been subjected to ESD will fail immediately upon being put
back into service. Usually a board will operate for a few days, or months, then fail.
•
•
•
If the hot tub runs only a few days, the customer thinks you provided poor service.
If the hot tub runs only a few months, the customer thinks the circuit board was a low quality
product.
The customer loses use of the hot tub. You lose money because you must go back to make it
right. Jacuzzi Premium loses its reputation for quality.
2.2 Avoiding ESD Damage
We can’t prevent static charges from building up within us as we go about our jobs, so
we must do three things to protect circuit boards from getting zapped:

Never transport or ship circuit boards - good boards or bad boards - except in
the static protective bags.
Never remove the board from the static protective bag unless you are ready to
install it in the hot tub.
After removing the bad board from the hot tub, A) lay it on the ground, B) remove
the replacement board from the static protective bag, C) lay the replacement board
on the ground, D) place the bad board in the bag from which you removed the re-
placement board, E) return bad board(s) to Jacuzzi Premium in undamaged sealed static protective
bags.
2.3 What About Wrist Straps And Special Mats?
The purpose of these devices is to keep the technician, the work surface and the circuit board at the same
electrical potential, and drain into ground any static charges which might build up. Proper use of the wrist
strap and special mat guarantees maximum protection against ESD damage.
2.4 Must Wrist Straps And Mats Be Used When Replacing A Circuit Board?
No, if you keep the spare board in the protective bag during transport and you observe a few simple tech-
niques during replacement.
The possibility of ESD damage to the circuit board during replacement will be minimal because of the hot
tub’s design and the way you normally work on it. Touching the ground lug will drain all built-up static charges
from your body much like a wrist strap would. Laying the bad board on the ground will tend to keep it neutral.
Touching a  nger to the grounding lug immediately before removing the good board from the bag will drain
charges built up by the rustling of your clothes. Laying the good board on the ground after removing it from
the bag will tend to keep it neutral. Another quick touch of the grounding lug before picking up the bad board
will drain built up charges. Slipping the bad board into the protective bag will allow it to be transported safely.
Another quick touch of the grounding lug before picking up the good board will again drain any charges built
up. In the process of installing the replacement board, you and the board will be grounded to the load box
or grounding lug, draining off charges you may build up during installation.

Operation Details:
• Temperature Adjustment: 65 to 104ºF (18 to 40ºC). Factory setting is 100ºF (38ºC).
• Underwater Light Operation: The light runs for 1 hour, then shuts off for increased bulb life.
• Jet Buttons Operations: The jets run for 20 minutes after activated then turn off automatically to con-
serve energy. Simply press a Jet Button to continue operation for an additional 20 minutes.
4.1 Setting Filter Cycle Start Time
Two methods for setting the  lter cycle start time are possible:
• Turn power on to the hot tub two minutes prior to the desired  lter cycle start time, or
• Press and hold both the Warmer and Cooler Buttons at the same time, then press and hold the Jet 1
Button to reset the control panel and start the power up sequence. During the power up sequence, the
previously set  lter cycle setting and temperature setpoint will be maintained. To select another  lter
cycle at this time, see section 4.2 below. The selected  lter cycle will start approximately two minutes
after the power up sequence ends.
Example: If you desire your  rst  lter cycle to begin at 10:00am, perform either of the above steps at 9:
58am. Filter cycle start time may vary slightly from the setpoint.
4.2 Programming Filter Cycles
Proper  ltration is an important key to maintaining the clarity of your hot tubs water. The hot tubs  ltra-
tion system is designed for unsurpassed effectiveness at removing debris and suspended particles
from the water anytime the water is circulated by the pump.
To select a pre-programmed  lter cycle or lockout mode, press and hold both the Warmer and Cooler
Buttons at the same time, then release. Then press either the Warmer or Cooler Buttons to select either
 lter mode FØ through L2.
