Pre-Delivery and Installation
Checklist
Most cities and counties require permits for exterior construction and
electrical circuits. In addition, some communities have codes requiring
residential barriers such as fencing and/or self-closing gates on property to
prevent unsupervised access to the property by children under the age of
5. Your dealer can provide information on which permits may be required
and how to obtain them prior to the delivery of your Cal Spa®.
We strongly recommend you have a qualied, licensed contractor perform
the installation of your in-ground or ported spa. The installation instructions
contained in the manual are for the use of a qualied contractor or
installer.
Consumers who choose to install their own in-ground spas bear sole
responsibility for any performance or warranty issues and may void portions
of their warranty as a result. For this reason, we strongly recommend they
hire an experienced professional for their installation.
For additional operating and installation information, please see your
selling dealer. To locate a dealer nearest you call 800-CALSPAS or visit

Planning the Best Location
Safety rst
Do not place your spa within 10 feet (3 m) of overhead power lines.
Make sure the spa is positioned so that access to the equipment
compartment and all side panels will not be blocked. Be certain that your
installation will meet all city and local safety codes and requirements.
Consider how you will use your spa
How you intend to use your spa will help you determine where you should
position it. For example, will you use your spa for recreational or therapeutic
purposes? If your spa is mainly used for family recreation, be sure to leave
plenty of room around it for activity. If you will use it for relaxation and
therapy, you’ll probably want to create a specic mood around it.
Plan for your environment
If you live in a region where it snows in the winter or rains frequently, place
the spa near a house entry. By doing this, you will have a place to change
clothes and not be uncomfortable.
Consider your privacy
In a cold-weather climate, bare trees won’t provide much privacy. Think of
your spa’s surroundings during all seasons to determine your best privacy
options. Consider the view of your neighbors as well when you plan the
location of your spa.
Provide a view with your spa
Think about the direction you will be facing when sitting in your spa. Do
you have a special landscaped area in your yard that you nd enjoyable?
Perhaps there is an area that catches a soothing breeze during the day or
a lovely sunset in the evening.
Keep your spa clean
Prevent dirt and contaminants from being tracked into your spa by placing
a foot mat at the spa’s entrance where the bather’s can clean their feet
before entering your spa. You may also consider keeping a small water-
lled basin nearby for bathers to rinse their feet before entering your spa.
In planning your spa’s location, consider a location where the path to and
from the house can be kept clean and free of debris.

3
Allow for service access
Many people choose to install a decorative structure 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 service. It is always best to
design special installations so that the spa can still be accessed.
Consider the best place for the outdoor equipment pack
(in-ground spas only)
The Designer Spa series requires an external equipment pack. When
locating the outdoor equipment pack, you will want to consider the
following:
The equipment pack must be located within a maximum of 15 feet•
from the spa.
Ensure the equipment running its normal ltration cycles does not •
make too much noise for spa owners and/or neighbors.
Ensure the equipment can be easily serviced for lter cleaning and •
periodic inspections in the location chosen.
If you are using a gas heater, you will need to consider wind and drafts•
as well as heater exhaust for proper heater placement. (See heater
owner’s manual for important location and safety information.)
The equipment base and heater must be placed on either a 3 1/2”•
cement slab or 3” paving stones.
Make sure the equipment area selected will not be in an area where•
water could run or stand.
If the area receives direct sunlight, you will want to provide some•
protection for the equipment portion of the equipment pack.
The equipment pack and heater are delivered separately. Do not cover gas
heaters unless properly vented. (See heater owner’s manual for important
safety information.)

Portable Spa Site Preparation
Your spa needs a solid and level foundation. The area that it sits on must
be able to support the weight of the spa, with water and the occupants who
use it. If the foundation is inadequate, it may shift or settle after the spa
is in place, causing stress that could DAMAGE YOUR SPA SHELL AND
FINISH.
Note: Damage caused by inadequate or improper foundation support is
not covered by the warranty. It is the responsibility of the spa owner to
provide a proper foundation for the spa.
Place the spa on an elevated foundation (preferably a 3” - 4” concrete
slab). Pavers, gravel, brick, sand, timbers or dirt foundations are not
adequate to support the spa. If you are installing the spa indoors, pay
close attention to the ooring beneath it. Choose ooring that will not be
damaged or stained.
If you are installing your spa on an elevated wood deck or other structure, it
is highly recommended that you consult a structural engineer or contractor
to ensure the structure will support the weight of 150 pounds per square
foot.
To properly identify the weight of your new spa when full, remember water
weighs 8.33 lbs. per gallon. For example, an average 8’ spa spa holds
approximately 500 gallons of water. Using this formula, you will nd that
the weight of the water alone is 4,165 lbs. Combined with the dry weight
of the spa you will note that this spa will weigh approximately 5,000 lbs.
when full of water.
Note: It is strongly recommended that a qualied, licensed contractor
prepare the foundation for your spa.
Your Cal Spas®retailer can help you with your foundation and more. Your
retailer has a wealth of information and experience about how to get the
most out of your spa and can provide you with a full line of accessories
that are designed to complement your spa and increase your enjoyment.
In-Ground Spa Site Preparation
Ensure there is enough room for the spa and equipment.•
The equipment pack must be located within a maximum of 15 feet•
from the spa.
Plan for proper electrical and gas service to both the equipment area•
and spa side.
Ensure the required at, level foundation can be constructed in the •
area chosen.

5
The spa must be properly back-lled with wet sand, underneath and •
on all four sides.
The nal architecture must include permanent ground coverage within •
a 10 feet radius of the spa.
Never place any spa in a sealed area. Water must be able either to be•
absorbed into the surrounding area or channeled away. Water build-
up under and/or around the spa, will cause the spa to oat out of the
ground.
Grading Prior to Excavation
Selection of the Designer Spas site will determine how much grading will
have to be accomplished prior to the actual dig for the spa. Naturally, a
level area is best because it will require the least amount of preparation for
the dig, but in many cases there is no level area, therefore, the site must
be prepared to accept the Spa prior to dig. The spa site should be elevated
slightly higher than the surrounding area
When dealing with slopes, the severity of the slope will determine if
retaining walls must be built in order to have a level area for the spa. If the
slope is relatively minor, contact your local building safety.
Site Excavation – Hard Bottom
For hard bottom placement for in-ground spas, you will need a smooth and
at concrete surface at least 4” thick as large as the bottom contact points.
Be sure not to seal the bottom off and making a sealed box. You will need
adequate water drainage for escape under the spa. A gravel beds around
the concrete base will help with this.
Site Excavation – Sand Bottom
With the spa area and all elevations planned including your decided type
of decking, you are now ready to proceed with the dig. An ideal excavation
is one that is as close as possible to the dimensions of the spa shell, but
with the following rules in mind. The excavation should be 2” to 4” deeper
than the actual spa for your sand bed. The sand bed is to level the spa
shell and provide a perfect support base with no voids when the spa is
lowered into the hole. Your excavation should be approximately one foot
longer and one foot wider than the spa shell. This will allow for a six inch
over dig all the way around the spa once it is in place. Additional hand
excavation will be required to insure the skimmer will t in the excavation
when attached to the spa.
Sand or rock dust must be used to bed the shell into the excavation and
for backll. In no event is dirt to be used. One of the easiest ways to know
how much sand is needed to be placed on the bottom of the excavation is
to set a grade stake at all four corners, and one on each side of the center
line in the bottom of the hole. If there are areas that are deeper than 2” to
4”, these can be lled with sand and are of no consequence.

6
Getting the Spa Into Your Yard
Check the Dimensions of Your New Cal Spa®
The Cal Spas® specication chart lists your spa’s model and its dimension
as it sits on the delivery cart. During delivery, the spa must remain on the
delivery cart at all times. Compare the dimensions to the width of the gates,
sidewalks, and doorways along the delivery route. It may be necessary for
you to remove a gate or partially remove a fence in order to provide an
unobstructed passageway to the installation location.
Plan the Delivery Route
Consider the following when planning your delivery route:
Check the width of gates, doors and sidewalks to make sure your spa•
will pass through unobstructed. You may have to remove a gate or
part of a fence to allow for adequate width clearance.
Are there low roof eaves, overhanging branches or rain gutters that•
could be an obstruction to overhead clearance?
8’ spas need at least 42” wide gate and 9’ height clearance.•
If the delivery route will require a 90º turn, check the measurements at•
the turn to ensure the spa will t.

7
Are there protruding gas meters, water meters or A/C units on your•
home which will cause obstructions along the delivery path to your
yard?
Are there stairs in your delivery route? If so, you must consult your Cal•
Spas®dealer prior to delivery to make adequate preparations.
Special Circumstances
The use of a crane for delivery and installation may become necessary if
you are unable to provide an adequate delivery route. It is used primarily
to avoid injury to your spa, your property or to delivery personnel. Your Cal
Spas®dealer may be able to assist you with the arrangements. If your spa
delivery requires the use of a crane, the cost of a crane is generally not
included in the standard delivery service.

Electrical Requirements
Electrical Requirements – US and Canada
240 Volt Electrical Installation
All 240V spas must be permanently connected (hardwired) to the power
supply. These instructions describe the only acceptable electrical wiring
procedure. Spas wired in any other way will void your warranty and may
result in serious injury.
This is the only acceptable electrical wiring procedure. Spas wired in any
other way will void your warranty. See the wiring diagram on page 9.
When installed in the United States, the electrical wiring of this spa must
meet the requirements of National Electric Code, ANSI/NFPA 70-2008 and
any applicable local, state, and federal codes. The electrical circuit must
be installed by an electrical contractor and approved by a local building /
electrical inspector.
