SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should be observed
including the following:
READ AND FOLLOW ALL
INSTRUCTIONS
1. WARNING - To reduce the risk of injury, do not permit children to use this product
unless they are closely supervised at all times.
2. DANGER - RISK OF CHILD DROWNING. Extreme caution must be
exercised to prevent unauthorized access by children. To avoid accidents, ensure that children
cannot use this spa unless they are supervised at all times.
*NOTE: A wire connector is provided on this unit to connect of a minimum No. 6 AWG
solid copper conductor between this unit and any metal equipment, metal enclosures of electrical
equipment, metal water pipe, or conduit within 5 feet (1.5m) of the unit.
3. DANGER - RISK OF ELECTRIC SHOCK. Install spa at least five (5)
feet (1.5M) from all metal surfaces. A spa may be installed within five (5) feet (1.5M) of metal
surfaces if, in accordance with the National Electrical Code, each metal surface is permanently
connected by a minimum No. 6 AWG (8.4mm) solid copper conductor attached to the wire c
onnector on the terminal box. A grounding lug is provided for this purpose.
4. DANGER - RISK OF INJURY. The suction fittings in this spa are sized to
match the specific water flow created by the pump. Should the need arise to replace the suction
fittings or the pump, be sure that the flow rates are compatible.
*NOTE: Never operate the spa if the suction fittings are broken or missing. Never replace a suction
fitting with one rated less than the flow rate marked on the original suction fitting.
5. DANGER - To reduce the risk of injury to persons, do not remove the suction grate.
Suction through drains and skimmers is powerful when the jets in the spa are in use. Damaged
covers can be hazardous to small children and adults with long hair. Should any part of the body
be drawn into these fittings, turn off the spa immediately. As a precaution, long hair should not
be allowed to float in the spa.

6. WARNING. Install the spa so that water can be easily drained out of the compartment
containing electrical components so as not to damage equipment. When installing the spa make
sure to allow for an adequate drainage system to deal with any overflow water. Please allow for
at least 2 feet of clearance around the perimeter of the spa to provide enough room to access
for servicing. Contact your local dealer for their specific requirements.
7. WARNING - TO REDUCE THE RISK OF INJURY:
(A) Reminder - Never allow anyone to dive into a spa. Always enter feet first.
(B) Always enter and exit a spa slowly.
(C) Do not use the spa alone.
(D) Before entering the spa, always measure the water temperature with an accurate
thermometer. Tolerance of water temperature regulating devices can vary as much as
plus/minus 5° F (3° C).
(E) Persons suffering from obesity or with a medical history of heart disease, diabetes, high
or low blood pressure or circulatory system problems should consult a physician before
using the spa.
(F) Since excessive water temperatures have a high potential for causing fetal damage during
early months of pregnancy, pregnant or possibly pregnant women should limit spa water
temperatures to 100° F (38° C).
(G) Excessive water temperature can be dangerous. The water in the spa should never exceed
104° F (40° C). Water temperatures between 100°F (38˚C) and 104°F (40˚C) are

extended use (exceeding 10 minutes) and for young children. Long exposures at higher
temperatures can result in hyperthermia.
(H) The use of alcohol, drugs, or medication before or during spa use may lead to
unconsciousness with the possibility of drowning.
(I) Persons using medication should consult a physician before using a spa since some
medication may induce drowsiness while other medication may affect heart rate, blood
pressure and circulation.
(J) The spa should be covered with an approved locking cover when not in use,
to prevent unauthorized entry and injuries.

5. JET DIVERTER VALVE
Located on the topside of the spa, this valve physically diverts the flow of water from one jet zone
of the spa to another jet zone.
Be sure that no sand or particles are brought into the spa as they will cause the diverter to seize
up. It is best to turn the diverter valve only when the pump is turned off.
Your new Master Spa features a variety of jet styles. All jets,
regardless of style return the water to the spa. Air is mixed
with the water by using the air controls (if equipped) creating
a gentle to most vigorous massage. Water flow is adjusted
by simply turning the outer face of the jet. Your Master Spa
will have a combination of pulsating, rotating, dual pulsating
and directional adjustable jets. The Legend Series and most
of the Down East 3 and 4 pump systems, feature the
Master Blaster Foot Therapy System.

6. CASCADE WATERFALL / LAMINAR FLOW VALVE
Located on the topside of the spa, this valve adjusts water flow to the cascade waterfall and the
Laminar Flow Jets. This feature is available on the Legend Series only. NOTE: See “Maintenance
Recommendations” for instructions on cleaning your Laminar Flow Jets.
NOTE: When water features are not going to be used for an extended period of time, turn valve slightly
to allow some water to flow when pump is on to prevent stagnent water from developing in the
water lines.
7. AIR CONTROL VALVES
These are located around the top of your spa. You may increase or decrease the force of your jets
by opening or closing the air control valves. Typically, one dial controls the air to water ratio and
mix to one group of jets. When not in use the air controls should be kept in the closed position,
as air bubbles tend to cool the water. NOTE: Only available on Legend Series Spas. Down East Spas
automatically inject air.
8. TOPSIDE CONTROL PANEL
You may safely control spa functions from inside or outside your spa using the Topside Control
Panel. This Panel is used to control the water temperature, pumps, the spa light, automatic
filtration cycles and other advanced functions. The digital display will give you a constant

Slice Valve and Pump Union
19. MAIN PUMP
This produces water flow through the main jets in the spa. The first pump may be operated on
two speeds. Low speed will produce efficient water circulation during filtration and gentle jet
action. High speed should be used for maximum jet action. The main pump is controlled by the
“Jets” or “Jets I” button on the Topside Control Panel or by using the Personal Remote Control
next to the Aqua Pressure Seat (Legend Series only).

GLOSSARY OF SPA TERMINOLOGY
20. SECONDARY PUMP

SITE PREPARATION / GENERAL GUIDELINES
Portable spa installation is simple when properly planned. To that end, it is important that you read the
following information carefully and consult with your Master Spas dealer.
1) Access - The actual dimensions of your new spa will determine the amount of space that is needed in
moving the spa from curbside to its final installation area. Be sure to measure side yard dimensions,
gates or doors and vertical obstructions such as roof overhangs and overhead cables. Any other space
limiting obstacles such as trees or shrubs must be evaluated.
2) If the spa is being installed indoors, dimension limitations such as stairs, ceilings and walls must
be taken into consideration. Please have your Master Spas dealer or delivery service review site
or installation plans prior to delivery.
3) Surface/Pad Requirements - When your new spa is filled with water and bathers, it may weigh as
much as several tons. It is imperative that the base beneath the spa can support the actual weight.
The spa must be on a uniformly firm, continuous, and level surface. The recommended foundation
is a concrete pad with a minimum thickness of four (4) inches with steel reinforcement bars crossed
throughout the pad.
IMPORTANT
When installing your spa indoors, on a wood deck, or balcony, the same load requirements must
be met. Total load may be as much as 90 pounds per square foot. You should speak with a qualified
contractor or your local building department to confirm that your surface is adequate for supporting
a spa. Be sure to locate your spa so that equipment remains above grade and is not subject to
flooding.
The equipment side(s) of the spa must be accessible in the event that future service is needed. Periodical
maintenance checks require entry into the equipment bay. When possible, it is wise planning for the
future to leave access to all sides of the spa in the event your spas plumbing requires maintenance.
Your spa warranty does not cover the cost of providing access for service.
GENERAL CONSIDERATIONS FOR OUTDOOR INSTALLATION
Again, proper planning will increase your total enjoyment factor with your new spa. Listed below are
some additional items to consider when planning your installation.
18
DO NOT DIVE.
• How spa will complement landscaping
and vice versa
• View from inside spa and view of spa from
inside of home
• Exposure to sunlight and shading from trees
• Privacy
• Getting to spa from house and return
• Proximity to dressing rooms and bathrooms
• Storage for spa chemicals
• Local building codes (if applicable)
• Power cable
GENERAL CONSIDERATIONS FOR INDOOR INSTALLATION
Installing your spa indoors creates an entirely different set of considerations. Here again, with proper
planning, no matter what room your spa goes in, it will be your favorite room.
• Work with your Master Spas dealer and
contractor to insure all local building, electrical
and plumbing codes are met
• Plan for a floor drain to drain off excess water
or for draining and cleaning your spa
• A ventilation fan may be necessary due
to high humidity created by your spa
• Finished material in your spa room should also
be capable of withstanding increased humidity

INSTALLATION INSTRUCTIONS
1. Put spa in final position that allows for access to equipment and spa components.
2. Remove front side panel (This is the side where the main topside control panel is located) so
electrical can be hooked up to the spa system pack. Panels are removed by unscrewing the screws
in the corner sections and then lifting up the panels out of the retaining tracks. NOTE: If your spa is
equipped with Master Select panels, you will need to remove the Phillips mounting screws instead
of the corner screws.

3. Be sure all pump and heater unions are secure. Each pump has 2 unions and the heater has
2 unions. A newly delivered spa may have loose unions caused in transporting the spa. Check
that all slice valves are open, in the up position. Again, the slice valves may become closed during
transportation of the spa.
4. Fill spa at least 1" above the filters. We recommend filling the spa through the filter area.
5. Turn the power on to the spa. Spa will go through its priming mode. This lasts approximately
5 minutes.
6. Be sure the jets in your spa are open by turning the face of the jet.
Note: The Master Blasters are only turned on/off through the use of the “Jets 3” button or the
diverter valve (if equipped).
