IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
DANGER To reduce the risk of injury, do not permit children to use this product unless
they are closely supervised at all times.

WARNING - RISK OF CHILD DROWNING. Extreme caution must be exercised to prevent
unauthorized access by children. To avoid accents, ensure that children cannot use a
spa or hot tub unless they are supervised at all times.

DANGER To reduce the risk of injury to persons, do not remove suction fitting covers.

Spa location must accommodate sufficient drainage of water around the base of the
structure, as well as the power source compartment.

Prolonged immersion in water that is warmer than normal body temperature can result
in a dangerous condition known as HYPERTHERMIA. The causes, symptoms, and
effects of hyperthermia may be described as follows: several degrees above the
normal body temperature of 98.6˚F. The symptoms of hyperthermia include dizziness,
fainting, drowsiness, lethargy, and an increase in the internal temperature of the body.
The effects of hyperthermia include (1) unawareness of impending hazard, (2) failure
to perceive heat, (3) failure to recognize the need to exit spa, (4) physical inability
to exit spa, (5) fetal damage in pregnant women, (6) unconsciousness resulting in
danger of drowning. WARNING The use of alcohol, drugs or medication can greatly
increase the risk of fatal hyperthermia in hot tubs and spas.

DANGER - RISK OF ELECTRICAL SHOCK. Install at least 5 feet (1.5m) from all metal
surfaces. (A spa may be installed within 5 feet of metal surfaces if each metal surface
is permanently connected by a solid copper conductor attached to the ground bar
on the terminal box that is provided for this purpose. Refer to NEC and local codes in
effect at the time of installation.)

A ground or bonding bar is provided on the control box to permit connection of a solid
copper bonding conductor between this point and any equipment, metal enclosures
of electrical equipment, metal water pipe, or conduit within 5 feet (1.5m) of the unit as
needed to comply with local requirements.

Bond accessible metal to the dedicated connector on the equipment grounding bus,
bond the equipment ground bus to the local common bonding grid as part of the
installation in the form of (1) a reinforced concrete slab for support, (2) a ground plate
provided beneath the hot tub or spa, or (3) a permanent ground connection that is
acceptable to the local inspection authority.

DANGER RISK OF ELECTRICAL SHOCK. Do not permit any electrical appliance such as
a light, telephone, radio, or television, within 5 feet (1.5m) of a spa or hot tub.

To reduce the risk of injury:

The water in a spa or hot tub 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 extended use (exceeding 10-15
minutes) and for young children.
Excessive water temperatures have a high potential for causing fetal damage during the
early months of pregnancy. Pregnant or possibly pregnant women should limit spa
or hot tub water temperatures to 100˚F (38˚C).
Wholesale 2

Before entering the spa or hot tub, the user should measure the water temperature with an
accurate thermometer.

The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to
unconsciousness with the possibility of drowning.

Persons suffering from obesity or with a medical history of heart disease, low or high blood
pressure, circulatory system problems, or diabetes should consult a physician before
using a spa or hot tub.

Persons using medication should consult a physician before using a spa or hot tub since
some medication may affect heart rate, blood pressure, and circulation.

Wet (Plumbing) Connections
The control system can be installed wherever it may be convenient, however, it is supplied
with a pressure switch. Therefore, it is only possible to install the heater on the pressure
side of the of the plumbing system. (If you find it necessary to install the heater on the
suction side of the plumbing system, please contact Hydro-Quip for further information).

Spa Light
Your control may contain a high intensity, low
voltage light to enhance nighttime use.

This illustration shows how and where to
find the bulb for replacement. It also shows
the mounted spa light with a replacement
(colored) lens. Colored lenses will further the
enhancement of the light. Simply snap on or off
to change the mood of your spa.

Pressure Switch
The function of the pressure switch is
to turn the heater off if the pumps stops
operating or if there is a restricted water
flow (dirty filter, obstruction in the spa
plumbing etc.)
Adjustment may be required if you
observe a flow related problem (FLO or
FLC on spa-side display) if adjustment is
required follow the next steps carefully.
IMPORTANT: After any pressure switch
adjustment, it is important to test the
control by turning on the pump low speed
and heater. While Operating, unplug the
pump, the heater must turn off. If the heater stays on, plug the pump back in and readjust
the pressure switch to achieve proper operation.
Adjustment:
1) With power to system turned OFF, remove the wires from the pressure switch terminals
(secure wires safely to prevent any chance of electrical shock).
2) Use Temperature adjustment key to move “set point” temperature to its lowest setting.
3) Turn power to the system ON and activate the low-speed pump.
4) Place an Ohmmeter across the pressure switch terminals to verify an OPEN circuit.
5) Rotate the pressure switch adjustment screw counter-clockwise until the Ohm-meter
indicates a CLOSED circuit.
6) Turn pump OFF and verify that the pressure switch circuit is once again OPEN.
7) Turn power to the system OFF and reconnect pressure switch wires. Reapply power to
the system and operate the spa or hot tub as normal.

OPERATIONAL CONSIDERATIONS
The following describes situation you may encounter and situations to be aware of.

Warm Weather Conditions
Since your spa will normally be expected to maintain warm to hot water ready for use, a
great deal of attention has been directed to the energy conservation detail of insulation
so as to keep electrical costs down. Energy conservation efficiency may be achieved by
extensive insulation of the skirt, plumbing and spa shell, and in some climates full foam
insulation may have been provided.
This energy conservation feature may cause an inconvenience during warmer times
of the year. During warm periods of the year, the temperature within the equipment
compartment can elevate to a point that the pump will automatically turn off for a short
period of time (15-30 minutes) to allow the pump to cool down before automatically
restarting. This cool down feature will not harm your spa but serves only to protect the
pump from damage and as an indicator that it is too hot. To minimize this occurrence,
refrain from using your Hydrotherapy Jets for prolonged periods of time during warm
seasons.
The jet pump chosen for your spa has been specifically sized for maximum performance
and your Hydrotherapy enjoyment.

Filtration System
Please refer to your Spa Manufacturer’s owner’s manual regarding the operation,
maintenance, and cleaning of your filtration system.
Dirty or clogged filters can cause a water flow restriction and you may experience difficulty
in reaching and/or maintaining desired heat levels.

Winterizing
When freezing weather and/or power losses are expected, contact your local spa dealer
for freeze protection or winterizing recommendations for both the spa and the equipment
system. Freeze related damage is not covered by the warranty.

Chemical Water Treatment
Your dealer is familiar with local water conditions and which chemicals are compatible with
and designed specifically for your spa. This is the best person to advise you on proper
water quality management.
The one thing you can do to insure years of trouble free equipment operation is to
maintain proper water chemistry.
Two basic goals of the chemical water treatment are sanitizing and balancing the water.
Sanitizing simply means keeping the water free from living microorganisms including
algae, bacteria, and viruses. The current most popular chemicals for sanitizing include
chlorine, bromine, and ozone.
Balancing water means establishing a balance among pH, total alkalinity, and total
hardness. Water that is unbalanced can corrode the spa and it’s support equipment or
leave deposits of minerals. Properly balanced water is essential to allow the sanitizing
chemical to work effectively. There are numerous chemical additives to help you in
controlling pH, total hardness, and total alkalinity. NEVER use softened water when filling
your spa. Softened water is extremely corrosive to metal parts of the spa equipment and
may lead to unforeseen failure.
Sometimes, despite your most diligent efforts, your water may become too far out of
balance to be managed chemically. At this point it is probably better to drain and clean the
spa and start over with fresh water.
Equipment failure caused by improper water chemistry will not be covered under warranty.

message. These messages will be helpful when communicating with your local dealer or
qualified technician if a problem should arise.

Pressure or Flow Switch Activated – The flow or pressure switch
is sensing water pressure or flow while the pump is not running. To clear
the error, try cycling the pump through low and high speeds. If this error

will be deactivated until the water cools to 109°F. Be sure to check the
actual temperature with an accurate thermometer.

2 – The spa water has exceeded 119°F. The heater will deactivate while
the pump and accessory will still operate. The air blower (if equipped) can
be activated to help cool the water. WATER MUST BE BELOW 119°F AND
POWER MUST BE RESET TO CLEAR THE “HL ERROR ”
