Important Safety Instructions for all Spa Owners
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY!
This spa was manufactured to meet the standards and specifications outlined in the “Virginia Graeme
Baker Pool and Spa Safety Act” (VGB Safety Act). When installing and using this spa, basic safety
precautions should always be followed, including:
1. DANGER: RISK OF INJURY: (For cord and plug connected units):
• Replace damaged cord immediately
• Do not bury cord
• Connect to a grounded, grounding type receptacle only.
WARNING: (For units with a Ground Fault Circuit Interrupter (GFCI):
This product is provided with a Ground Fault Circuit Interrupter GFCI on the end of the spa’s power cord. This GFCI must be
tested before each use. With the product operating depress the “test” button on the GFCI the spa should not operate. Depress the
“reset” button on the GFCI. The product should now operate normally. If the spa fails to operate in this manner, there is a ground
current flowing indicating a possible electric shock. Disconnect the power until the fault has been identified and corrected by a
certified licensed electrician.
2. WARNING: (For permanently installed units):
The electrical supply for this product must include a suitably rated switch or circuit breaker to open all ungrounded supply
conductors to comply with Section 442-20 of the National Electric Code. ANSI / NFPA 70-1987. In addition, all 230-volt
installations must be protected by a 230-volt Ground Fault Circuit Interrupter GFCI. Any GFCI circuit breaker used in the house
panel must read current returning through the neutral conductor. 230-volt 2 conductor GFCI circuit breakers will not operate
correctly for your application.
3. DANGER: RISK OF SEVERE INJURY OR DROWNING!
• Extreme caution must be exercised to prevent unauthorized access by children.
• To avoid accidents, ensure that children do not use this spa unless supervised at all times. Adult supervision is a critical safety
factor in preventing children from drowning.
• Use the straps and clip tie downs to secure the spa cover when not in use. This will help discourage unsupervised children from
entering the spa. Keep the spa cover secure in high-wind conditions.
• There is no representation that the cover, clip tie-downs, or actual locks will prevent access to the spa.
4. DANGER: RISK OF SEVERE INJURY OR DROWNING!
• Keep hair, loose articles of clothing or hanging jewelry away from suction fittings, rotating jets or other moving components
to avoid entrapment that could lead to drowning or severe injury.
• Never use the spa unless all suction guards, filter, filter lid, or skimmer assembly are installed to prevent body and/or hair entrapment.
• Never operate or use the spa if the filter, filter lid, or skimmer assembly are broken or any part of the skimmer assembly is
missing. Please contact your dealer or nearest service center for service.
• The suction fittings and suction covers in this spa are sized to match the specific water flow created by the pump(s). If it is
necessary to replace the suction fittings, suction covers or pump(s), be sure that the flow rates are compatible and are in
compliance with the VGB Safety Act.
• Never replace a suction fitting or suction cover with one rated less than the flow rate marked on the original suction fitting.
Using improper suction fittings or suction covers can create a body or hair suction entrapment hazard that may lead to drowning
or severe injury.

such appliances are built-in by the manufacturer.
• Never bring any electrical appliances into or near the spa.
• Never operate any electrical appliances from inside the spa or when you are wet.
• Permanently installed units: The electrical supply for this product must include a suitably rated switch or circuit breaker to
open all ungrounded supply conductors to comply with section 422-20 of the National Electrical Code/USA,
ANSI/NFPA 70. The disconnecting means must be readily accessible and visible to the spa occupant but installed at
least 5 feet (1.5m), from the spa.
• Permanently installed units: The electrical circuit supplied for the hot tub must include a suitable ground fault circuit interrupter
(GFCI) as required by NEC Article 680-42.
6. WARNING: RISK OF SEVERE INJURY OR DEATH!
• Extreme caution must be exercised to prevent diving or jumping into that the spa or slipping and falling, which
could result in unconsciousness, drowning, or serious injury. Remember wet surfaces can be very slippery.
• Never stand, walk or sit on the top railing of the spa.
• Always use care in and around your spa. The spa has many rigid, unyielding parts and many areas that become
wet and slippery; these are all potentially dangerous when rough play is permitted or if care is not used, particularly when entering
or leaving the spa.
7. WARNING: RISK OF HYPERTHERMIA (OVER-HEATING) CAUSING SEVERE INJURY,
BURNS, WELTS OR DEATH!
• Water temperature in excess of 104°F (40°C) may be injurious to your health.
• Refer to Hyperthermia section on this manual for specific causes and symptoms of this condition.
• 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
considered safe for a healthy adult.
• Lower water temperatures are recommended for young children (children are especially sensitive to hot water) and when spa
use may exceed 10 minutes.
• The Consumer Products Safety Commission/USA has stated that the water temperature in a spa should not exceed 104°F (40°C).
• Always test the spa water temperature before entering the spa. The user should measure the water temperature with an
accurate thermometer since the tolerance of water temperature regulating devices may vary as much as +/- 5°F (2°C).
8. WARNING: RISK OF SEVERE INJURY OR DEATH!
• Since excessive water temperatures have a high potential for causing fetal damage during the early months of pregnancy, if
pregnant or possibly pregnant, consult your physician before using a spa.
• Pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C).
• Persons suffering from obesity or a medical history of heart disease, low or high blood pressure, circulatory system problems,
diabetes, infectious diseases or immune deficiency syndromes should consult a physician before using a spa.
• If you experience breathing difficulties in association with using or operating your spa, discontinue use and consult your
physician.
• 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.
• Persons suffering from any condition requiring medical treatment, the elderly, or infants should consult with a physician before
using a spa.
• If you have any questions about your own fitness or whether you should soak in the spa, check with your physician.
• The use of alcohol, drugs, or medication before or during spa use may lead to unconsciousness with the possibility of
drowning.
• Never permit the spa to be used unless it is attended by at least one person other than the bather. Someone should be present
to lend assistance if the bather should be in trouble due to injuries, cramps, or drowning, especially in case of children.
9. WARNING: RISK OF SEVERE INJURY OR DEATH!
• Prolonged immersion in a spa may be injurious to your health.
• Observe a reasonable time limit when using the spa. Exposures at higher temperatures can cause high body temperature (over-
heating). Symptoms may include dizziness, nausea, fainting, drowsiness, and reduced awareness. These effects could possibly
result in drowning or serious injury.
• Never use a spa immediately following strenuous exercise. Enter and exit the spa slowly. Wet surfaces can be slippery.

Entrapment Risk
The Consumer Products Safety Commission/USA has reported that users of pools and spas have become entrapped
(stuck) to drain and/or suction fittings causing death, drowning, or serious injury (see diagram below). This spa was
manufactured to meet the standards and specifications outlined in the “Virginia Graeme Baker Pool and Spa Safety Act”
(VGB Safety Act). Entrapment risk can be minimized if proper precautions are taken.
Note: Suction covers must be replaced every 7 years.
1. DANGER: RISK OF SEVERE INJURY OR DROWNING! Hair entrapment: May occur if hair is entangled,
knotted or snagged in a drain suction or skimmer assembly. This has been reported in persons who when submerge themselves
underwater, allowing hair to come close and/or within the reach of the suction fittings, suction covers or skimmer assembly.
• Keep hair away from suction fittings, suction covers, filter, filter lid or skimmer assembly.
• Children are at risk for hair entrapment if swimming under water.
• Never allow children to play or get near the suction fittings, suction covers, filter, filter lid or skimmer assembly.
2. DANGER: RISK OF SEVERE INJURY OR DROWNING! Limb entrapment: May occur when a limb
becomes entrapped, inserted or sucked into a suction or outlet opening.
• Always keep suction fittings, suction covers, filter, filter lid or skimmer assembly in place when operating to avoid limb
entrapment.
• Never allow children to play or get near the suction fittings, suction covers, filter, filter lid or skimmer assembly.
3. DANGER: RISK OF SEVERE INJURY OR DROWNING! Body entrapment: May occur when part of the
torso becomes entrapped, inserted or sucked into a suction or outlet opening.
• Never allow children to play or get near the suction fittings, suction covers, filter, filter lid or skimmer assembly.

Hyperthermia
Prolonged immersion in hot water may induce hyperthermia (overheating). The use of alcohol or drugs can greatly increase
the risk of fatal hyperthermia in spas. A description of the causes, symptoms, and effects of hyperthermia are as follows:
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body
temperature of 98.6°F (37°C). The symptoms of hyperthermia include drowsiness, lethargy (fatigue), and an increase in
the internal temperature of the body (feeling of being too hot). The effects of hyperthermia include:
• Unawareness of impending hazard.
• Failure to perceive heat.
• Failure to recognize the need to exit spa.
• Physical inability to exit spa.
• Fetal damage in pregnant women; and
• Unconsciousness and DANGER of drowning.
Important Additional Safety Instructions
When using this electrical equipment, basic safety precautions should always be followed, including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Permanently installed units: A green colored terminal or a terminal marked G, Gr, Ground, Grounding or the symbol* is
located inside the supply terminal box or compartment. To reduce the risk of electric shock, this terminal must be connected to the
grounding means provided in the electric supply service panel with a continuous copper wire equivalent in size to the circuit
conductors that supply this equipment (*IEC Publication 417, Symbol 5019).
3. A grounding bar is provided on the outside of the equipment box. To reduce the risk of electric shock, connect the local
common bonding grid in the area of the spa to this grounding bar with an insulated or bare copper conductor not smaller than
No. 6 AWG (10 mm²).
4. All field installed metal components such as rails, ladders, drains or other similar hardware within 10 feet (3m) of the spa shall be
bonded to the equipment grounding buss with copper conductors not smaller than No. 6 AWG (10 mm2).
5. SAVE THESE INSTRUCTIONS.

10
WARNING: Proper drainage is required. The installation must not allow the spa equipment bay to become flooded or wetted
(by external water). It is your responsibility, and the responsibility of any installation contractor you hire, to make sure that all
applicable codes and/or local construction requirements are met. If in doubt, refer to the building authority responsible for
approving the proposed installation site.
WARNING: For spas that are to rest on balconies, roofs or other platforms not specifically tied into main
structural support consult a professional Structural Engineer with experience in this type of application.
Selecting electrical mode
q
WARNING! DO NOT STORE SPAS OUTDOORS WITHOUT PROPER WATER LEVEL.
A spa stored outside in direct sun, without proper water level, uncovered or under a tarp/cover, can accumulated temperatures that will damage the
spa, its components and void the warranty. Only store an empty spa indoors or in the shade.
One-pump (100 SERIES) models
q
Will you operate the spa on 120- or 240-volts heater?
Your spa comes ready to plug into a standard 120 volt / 15-amp outlet for power. However, the heater can be converted from 120-volt 1000 watts, to
240 volt 4000 watts, with a hard-wired power supply installed by a licensed certified electrician. Please read the following to help with your decision.
120 volts:
When connected with the 120-volt plug, the heater is 1000 watts and operates only in the low speed filtration mode. When the jet pump
operates, the heater will turn off. This means the water will begin to cool while using the jet pump and the heat recovery time will take longer than it
will if wired 240 volts. Many find this adequate due to their mild climate or shorter length of usage. Additionally, many prefer not to hire an electrician
for the installation.
240 volts:
When hard-wired to a 240-volt power supply, the heater is 4000 watts. It can operate on a 30- or 40-amp service.
On a 30-amp service
the heater will not operate with the jet pump. However, the higher heater wattage will greatly increase the heat recovery time.
The 30-amp circuit is often selected when there is limited available power as seen in some older homes.
On a 40-amp service
the heater will operate with both high and low speed. This means the spa will heat while you operate the jet pump.
q
If you have decided to operate your spa on 120 volts, will your electrical cord reach an outlet?
Locate your spa so that the GFCI plug and cord will reach a standard 120 volt / 15-amp outlet*, but not closer than 5 feet (1.5m). Do not use an
extension cord. Use of an extension cord will void your warranty. To extend the power cord, with a Philips screwdriver remove the access panel, locate
the coiled GFCI cord, uncoil and extend the cord. Ensure that the cord is routed through the notch at the lower center of the opening before reinstalling
the access panel. Do not connect to the outlet until the spa is filled with water (see page 13).
q
If you have decided to convert your spa to 240 volts
, a certified licensed electrician is required for the electrical installation. In this case, you
may want to consult with your electrician before final positioning of your spa. Have your electrician see pages 18-20 for conversion instructions.
*To avoid nuisance circuit breaker tripping, it is best to use an outlet on a circuit which does not supply power to any other major running appliance. This can be checked by turning off the circuit
breaker that supplies the intended outlet and verifying that no other electrical devices no longer work, such as a refrigerator, dishwasher, washing machine, coffee maker, hair dryer, etc.
Two-pump (200 SERIES) models:
q
Electrical power supply:
a certified licensed electrician is required for the electrical installation. You may want to consult with your electrician
before final positioning of your spa. Have your electrician see pages 15-17 for more information.
Choosing A Location
IMPORTANT: Because of the combined weight of the spa, water and users, it is extremely important that the base upon which the
spa rests be smooth, flat, level and capable of uniformly supporting this weight, without shifting or settling, for the entire time the spa
is in place. If the spa is placed on a surface which does not meet these requirements, damage to the skirt and/or the spa shell may
result. Damage caused by improper support is not covered under warranty. It is the responsibility of the spa owner to assure the
integrity of the support over time. We recommend a poured, reinforced concrete slab with a minimum thickness of 4 inches (10 cm).
Wood decking is also acceptable provided it is constructed so that it meets the requirements outlined above.

11
WARNING: In addition to maintenance of filters and water chemistry, proper ventilation is recommended to reduce
the risk of contracting a waterborne illness (e.g. an infection, bacteria or virus) and/or respiratory ailments that could be
present in the air or water. Consult a licensed architect or building contractor to determine your specific needs if
installing your hot tub indoors.
The spa must be installed in such a manner as to provide drainage away from it. Placing the spa in a depression without
provisions for proper drainage could allow rain, overflow, leaks from spa plumbing, and other casual water to flood the
equipment and create a wet condition in which it would sit in. For spas which will be installed below grade or recessed into
a floor or deck, install so as to permit access to the equipment, either from above or below, for servicing. Make certain
that there are no obstructions which would prevent removal of all cabinet side panels and access to the jet components,
especially on the side with the equipment bay.
CAUTION: If the spa is indoors or located in an enclosed area, proper ventilation should be discussed with an
Engineer or authority competent enough to understand the necessary provisions needed to vent moist or heated air
and air associated with chemical odors outdoors. When the spa is in use considerable amounts of moisture will
escape potentially causing mold and mildew. This can cause health risk. Over time, this can damage certain
surfaces, surroundings, and equipment.
Outdoor Location
In selecting the ideal outdoor location for your spa, we suggest that you take into consideration:
• The proximity to changing area and shelter (especially in colder weather).
• The pathway to and from your spa (this should be free of debris so that dirt and leaves are not easily tracked into
the spa).
• The closeness to trees and shrubbery (remember that leaves and birds could create extra work in keeping the spa
clean).
• A sheltered environment (less wind and weather exposure can result in lowered operation and maintenance costs).
• The overall enhancement of your environment. It is preferable not to place the spa under an unguttered roof overhang
since run-off water will shorten the life expectancy of the spa cover.
• For spas that are to rest on balconies, roofs or other platforms not specifically tied into main structural support,
consult a professional Structural Engineer with experience in this type of application.
• In the unlikely event that you should ever need to access or gain entry to any portion of the spa for servicing, it is
highly recommended that you plan your outdoor installation to provide full access to the entire spa. Please take this
into consideration when placing the spa in a deck or enclosed by a surrounding.
• Consider locating your spa away from any reflective surface or glass to prevent any damage to the spa and cabinet.
• Do not shim the spa. To ensure proper support the spa must sit flat on the intended foundation.
Indoor Location
For indoor installations many factors need to be considered before installing a spa indoors:
• Proper Foundation: Consult a Structural Engineer when considering a foundation that will adequately
support the spa the entire time it is in place. Proper support is critical especially if the spa is to rest on a
second story or higher. For spas that are to rest on balconies, roofs or other platforms not specifically tied into the
main structural support, you should consult a professional Structural Engineer with experience in this type of
application.
• Proper Drainage: It is extremely important to have in place measures to sufficiently handle excessive water
spillage. Be sure the flooring in which the spa rests on has adequate drainage and can handle the entire contents
of the spa. Be sure to make provisions for ceilings and other structures that may be below the spa’s installation.
Areas around your spa can become wet or moist so all flooring and subsequent furniture, walls and adjacent
structures should be able towithstand or resist water and moisture.
• Proper Ventilation: Proper ventilation should be discussed with an Engineer or authority competent
enough to understand the necessary provisions needed to vent moist or heated air and air associated with
chemical odors outdoors. When the spa is in use considerable amounts of moisture will escape, potentially
causing mold and mildew over time which can damage certain surfaces and/ or surroundings.
• Sufficient Access: In the unlikely event that you should ever need to access or gain entry to any portion of the
spa for servicing, it is highly recommended that you plan your indoor installation to provide full access to the entire
spa.
• Warranty: Damage caused by not following these guidelines or any improper installation not in accordance to local
codes or authorities is not covered under the spas warranty. Please consult your local state or city building
ordinances.
• Do not shim the spa. To ensure proper support the spa must sit flat on the intended foundation.

Spa Cover Installation
! WARNING: AVOID DROWNING RISK
•
Failure to follow instructions may result in injury or drowning.
•
Non-secured covers are a hazard.
•
Keep children away. People or objects cannot be seen under the cover.
•
Because of entrapment possibility, remove cover completely before entry of bathers.
•
Excess weight can break the insulating foam, bend the steel reinforcement and damage the cover. Do not allow people or pets to stand or
sit on the cover. Do not allow loads such as snow, leaves or anything else to accumulate on the cover. Do not use the cover as a table.
Caution, to avoid damage to the cover always remove the cover while adding chemicals to the spa water. This will prevent damaging chemical vapors
from being trapped under the spa cover. These vapors can prematurely damage the cover material and void the warranty.
When properly installed, the cover supplied with your spa meets the Manual Safety Cover requirements of ASTM F1346-91.
If you are installing your spa near a wall or with any type of structure on the outside, such as a gazebo, remember to allow access for cover removal.
To deter entrapment by somebody slipping under the cover, ensure that all latches supplied with the cover are securely screwed to the cabinet,
straps are inserted into the latches, the latches are locked, and the key is kept in a secure location.
Keep the spa covered when not in use to deter entry by unauthorized persons, reduce the loss of heat, and keep out rain and to keep foreign
materials from settling in the water.
Follow these steps to properly install the cover.
1. Place the spa cover on top of the spa. Ensure the cover flaps and straps are not under the cover. Ensure the cover is properly seated in its
final position.
2. Each strap is supplied with a cabinet latch snapped in place. Leave the cabinet latches at the end of the straps, but remove the bag
containing the screws and while lightly pulling downward on a strap, mark the center bottom of the latch (Fig 1). A piece of tape may be a
good method to do this. Mark each remaining strap in the same way.
3. Remove the strap by pinching the two barbs of the strap as indicated (Fig 2).
4. Hold the cabinet latch on the mark and using a Phillips screwdriver, drive three screws through the holes in the cabinet latch and into the
outside of the spa (Fig 3).
5. While the spa is not in use place the cover on top of the spa and snap all straps into the cabinet latches. To further protect against entry,
lock each latch by quarter turning the key clockwise (Fig 4). Store the key in a secure place.

Filling Your Spa
! WARNING: RISK OF PERSONAL INJURY!
• To decrease the risk of injury, drowning or entrapment, never leave your hot tub unattended for any reason while
the cover is open and accessible, especially to small children and animals!
• Precautions should be taken to minimize your exposure to chemical vapors (that could cause lung, brain, or skin
damage).
! CAUTION:
TO DECREASE BUILD UP ON COMPONENTS AND MINIMIZE SURFACE DAMAGE.
Never fill with water from a water softener. If your water is extremely “hard,” it is preferable to fill half-way with hard
water and the rest of the way with softened water. Water that is too soft can be corrosive to metal components.
! CAUTION
: Your spa is constructed of a very resilient and flexible polymeric material. It is designed to
flex as much as 2 inches (5cm) without damage. However, overfilling the spa and/or installing on a non-level surface for
extended periods of time can permanently distort the original shape of your spa, cause structural damage, effect the
sealing of the cover and void your warranty.
TO FILL THE SPA
Remove the access panel and ensure the drain valve is closed and the cap is secure (Fig 5).
Place a garden hose into filter area (Fig 7) and fill the spa with cold (never warm or hot) water 6 to 8 inches (15 to 20 cm)
below the top edge of the spa (Fig 6). If there is not enough water in your spa, the pump may suck air into the plumbing
system thereby damaging the pump or heater and void the warranty. Do not overfill, as the spa’s water level will rise as
each person enters the spa. Always keep the spa water level above the jet openings.

Draining the spa
! WARNING: RISK OF PERSONAL INJURY!
• To decrease the risk of injury, drowning or entrapment, never leave your hot tub unattended for any reason while
the cover is open and accessible, especially to small children and animals!
• Precautions should be taken to minimize your exposure to chemical vapors (that could cause lung, brain, or skin
damage).
Draining your spa on a regular basis rids the spa of dissolved solids and protects your spa equipment from the effects of
residual calcium hardness and total alkalinity problems. Depending upon usage, it may be as often as every three months.
To drain the spa, follow these steps:
1. Turn power off to the spa.
2. Remove the access panel and locate the drain valve (Fig 5).
3. Ensure that the drain valve is in the off position (as shown in Fig 5). Remove the cap (Fig 5) and attach a standard
garden hose to the drain valve (Fig 8).
4. Route the garden hose to a suitable location for water drainage. Open the drain valve (as shown in Fig 8). The spa
drains slowly.
5. The spa can only drain to the lowest jet. It may be necessary to manually remove the remaining water.
6. Before refilling your spa, ensure that the drain valve is in the off position and the cap is secured (Fig 5).

Two-pump (200 SERIES) models, FOR THE ELECTRICIAN
Installations that do not adhere to these instructions can expose users to electric shock and will void the warranty.
Power Requirements
240VAC, 60HZ, 50A, Class A GFCI-protected service (Circuit Breaker
rating 50A).
4 wires (hot, hot, Nuetral, ground).
GFCI PROTECTION:
The new service must be protected with by a GFCI
and a disconnect switch. The National Electrical Code requires that spas
connected to 240 volts circuits be equipped with a GFCI and disconnect
switch. See National Electric Code Articles 680-12 and 680-42. This spa
is not equipped with a 240-volt GFCI or a disconnect switch. A GFCI
must be installed by a certified licensed electrician.
OUTDOOR LOAD CENTER
: The addition of an outdoor load center such as a Siemens W0408ML 1125 or equal must be added to the
circuit. This type of load center provides both a GFCI and Disconnect Switch in a convenient configuration as required by the National
Electric Code. (See next page for suggested wiring configuration)
ISOLATED, DEDICATED 240 VOLT, 50 AMP CIRCUIT IS REQUIRED
An isolated, dedicated 240-volt 50-amp circuit is required to provide
the power necessary to properly operate the 240V equipment package.
PERMANENTLY HARD WIRED:
All 240-volt operations wiring must be permanently hard wired, installed in grounded conduit and
installed in compliance with the National Electrical Code and all local codes. Do not use an extension cord. Use of an extension cord
will void the warranty.
WIRE SIZING MUST MEET ELECTRICAL CODES:
All installations are different. Wire sizing must meet the National Electrical Code and all
local code specifications. 6/4 wire up to 100'
To make electrical connections, remove the access panel as shown in Fig 9. Locate the control box, remove the cover and make
connections.

FOR THE ELECTRICIAN,
CONVERSION FROM 120V TO 240V,
One-pump (100 SERIES) models
Installations that do not adhere to these instructions can expose users to electric shock and will void the warranty.
The conversion of the equipment package, from a factory installed 120-
volt system to a hardwired 120/240-volt system, must be completed by a
certified licensed electrician. This procedure will convert the heater from
120 volts (1000 watts) to 240 volts (4000 watts). All other electrical
components will remain 120 volts, so it will be necessary to include a
neutral wire in the new electrical service. It will also be necessary to
select how the heater will operate, thereby dictating the size of the new
electrical service. If the heater will operate only when the low-speed
pump is running, then a 30-amp service will be used, and the #10 dip
switch will be set to the
low amp
position (page 20). If the heater will
operate when both high and low-speed pumps are running, then a 40-
amp service is required, and the #10 dip switch will be set in the
high amp
position (page 20). Regardless of your choice, the following will also have
to be done.
1. Remove and discard the 120-volt GFCI power cord.
2. Remove and discard the white wire jumper between J32
and J11.
3. Move #10 dip switch to proper position: low amp for a
30-amp service, or high amp for a 40-amp service. See
page 10 to help with the decision.
4. When supplying the new 4 wire service, connect line 2 to
the terminal indicated by the dotted line in the above
diagram.
