Important Safety Instructions When installing and using this electrical equipment, basic safety precautions should always be followed, 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. WARNING: A wire connector is provided on this unit to connect a minimum 6 AWG (4.
11. WARNING: a. People with infectious diseases should not use a spa or hot tub. b. To avoid injury, exercise care when entering or exiting a spa or hot tub. c. Do not use a spa or hot tub immediately following strenuous exercise. d. Prolonged immersion in a spa or hot tub may be injurious to your health. 12. Caution: Maintain water chemistry in accordance to manufacturer’s instructions. Your spa can be a source of great pleasure.
Selecting electrical mode and a location 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. 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.
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.
Filling Your Spa Warning! 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. Remove the access door (Fig 1) and ensure the drain valve is closed and the cap is secure (fig 2).
System Operation 102 Initial Start-Up When your Spa is first activated, it will perform a self diagnostics test showing a series of numbers followed by Pr, then by -along with the low speed pump for approximately 7 minutes total. Also the internal clock that keeps track of the filtration cycles every 12 hours will start at that point. The system is preset to heat up to 100° F (37° C) and it is also preset to run on low speed for two hours (F2).
Standby Mode (SY) This function allows you to disable the equipment when the filter requires service without disturbing programmed filtration time. Press repeatedly (or hold it down) until it gets to 70° F (21° C) then press it one more time (within a couple of seconds) to enter the stand by mode. All spa functions are disabled except for freeze control. To exit from standby press any button and re-enter desire set temperature. Spa heating modes Your spa is factory set to Standard Heating (ST) mode.
Display Messages MESSAGE -- HH OH 1C SA Sb SN HL LF DR DY MEANING No message on display. Power has been cut off to the spa. Temperature unknown. Overheat -The spa has shut down. One of the sensors has detected 118°F (47°C) at the heater. Overheat" -The spa has shut down. One of the sensors has detected that the spa water is 110°F (43°C). Ice -Potential freeze condition detected. Spa is shut down. The sensor that is plugged into the "A" jack is not working. Spa is shut down.
FOR THE ELECTRICIAN, HU2 CONVERSION FROM 120V TO 240V Installations that do not adhere to these instructions can expose users to electric shock and will void the warranty. The conversion of the HU2 equipment package, from a factory installed 120 volt system to a hardwired 120/240volt 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).
FOR THE ELECTRICIAN, CONVERSION FROM 120V TO 240V continued: ELECTRICAL DATA FOR THE USE OF CERTIFIED LICENSED ELECTRICIAN WARNING: Shock Hazard!

Equipment Operation Air Injection Venturi Adjustment Air injection into the massage jet water flow may be controlled by turning the venturi dials located on either side of the spa. Surface Skim Filter The spa’s automatic surface skim filter is designed to remove floating debris and contaminants such as body lotions by drawing water through a specially formulated filter cartridge. It is critical that this element be routinely cleaned.
Water Chemistry Spa water chemistry (or water balance) affects the safety of your equipment as well as the appearance of your spa water. Water balance has five factors: pH, total alkalinity, calcium hardness, temperature and total dissolved solids. pH is the most critical but total alkalinity and calcium hardness must also be watched closely. Low calcium hardness can lead to corrosion of equipment, while high calcium hardness can lead to scaling, cloudy water and staining.
Water Chemistry (Continued) It is recommended that the spa be drained regularly depending on its size, location and the frequency of use. 1. Clean filter and cartridge periodically according to manufacturer’s instructions. 2. Keep the spa covered when not in use to reduce the loss of heat and to keep out leaves, dirt, and other foreign materials from settling in the water. 3.
Replacing the LED light. 6. Turn off power to the spa. 7. Using a Philips screwdriver, remove the access vent located on the outside of the spa, directly behind the filter (Fig 7.1). 8. Reach in and turn the white holder counter clockwise and gently pull it, with the attached wires, out the access hole (Fig 7.2). 9. Pull the LED light out of the light socket (Fig 7.3). 10. Install a new LED light, attach the white reflector turning clockwise and reattach the access vent with the screws.
Freeze Protection DO NOT ALLOW THE SPA TO FREEZE Caution, any damage caused by improper winterizing will void the warranty. You may want consider contacting a spa professional for winterizing service. If the spa is to be stored or transported in temperatures of 32°F (0°C) or lower, it is critical that the unit be fully winterized. To winterize the spa follow these steps: 1 2 3 The spa itself must be completely drained of water. See page 8 for draining instructions.
Frequently Asked Questions 1. Why does my spa not shut off? Your spa is designed to run from the time you plug it in to run until it reaches your desired temperature. Once desired temperature is reached then you can control the on/off with the buttons on the top control. For example: On the initial startup the spa will run for approximately 18 hours to reach 100°F (38°C). At that point the spa will shut off, and then the spa will maintain your desired temperature settings.
PURGING THE PUMP Sometimes after a water change (draining and refilling the spa), or initial start-up of the spa, there is no water flowing from the jets. You may hear the pump operating or even see the shaft of the pump motor turning, but have no water flowing from the jets. In addition to no flow out of the jets, you may even see an error message dr, dY, HH, OH, HL, or LF. All of these error messages can be caused by a lack of water flow. When this happens there is probably an air-lock in the pump.
Jet Tool This wrench is used to tighten the small 2 inch (5cm) diameter jets when needed. To tighten the jets, insert the hex portion of the wrench into the hexagon hole at the base of the jet and turn clockwise. Do not over tighten. Troubleshooting Guide SITUATION PROBABLE CAUSE ACTION NO HEAT OR HEAT TOO LOW Operating while spa cover is open. Ensure that spa cover is properly closed. Dirty filter Remove filter cartridge and clean. JETS WON’T COME ON No power to spa control.
Glossary of Terms Venturi dials Mounted on the lip of the spa or at the equipment shroud, to induce air to the jets. BYPASS CHECK VALVE Prevents water flow stoppage due to dirty filter. CONTROL BOX Basically the brain of the spa. Power is distributed to all functions of the spa, pumps, lights, heat, etc. DRAIN VALVE Used in the draining of the spa, looks like an outdoor faucet and fits a standard garden hose.
Your Spa’s Ozonator (Optional equipment) If you ordered your spa with the optional ozonator installed, you can confirm this by viewing the spa’s rating plate. The rating plate is located near the floor and equipment access door. As shown below, look in the option box to confirm the ozonator has been installed. The word “OZONE” will be seen. Further to verifying the ozone option is installed on your spa. If you look in the equipment compartment you will see a small black or blue box, about 2.6 inches by 3.
