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. 2. WARNING: To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times. WARNING: A wire connector is provided on this unit to connect a minimum 6 AWG (4.
12. Caution: Maintain water chemistry in accordance to manufacturer’s instructions. Your spa can be a source of great pleasure. It offers healthful stimulating recreation and is a delightful fun center for you, your family and friends. However, it contains large quantities of water and is deep enough to present inherent dangers to life and health unless the following safety rules are strictly observed. 13. Never permit the spa to be used unless it is attended by at least one person other than the bather.
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.
FOR THE ELECTRICIAN, CONVERSION FROM 120 VOLT 1KW TO 240VOLT 4KW HEATER 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 120volt 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).

System Operation 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 one hours (F1).
Additional Functions Spa heating modes Your spa is factory set to Standard Heating (ST) mode. This mode operates the heater whenever needed to maintain the programmed spa water temperature. (See Temperature Adjustment page 12). Advanced Optional Settings You have the option to enable other heating modes as explained below: standard, economy and sleep. To enable these heating modes, you must do the following steps. 1. Turn off power to the spa. 2.
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.
SKIMMER FILTER CLEANING OR REPLACEMENT OF THE FILTER CARTRIDGE End nut The spa’s automatic surface skimmer filter is designed to remove floating debris and contaminants, such as body lotions, by drawing water through a specially formulated filter cartridge element. It is critical that this element be routinely cleaned. End nut Filter cartridge Filter cartridge To Clean or Replace the Filter Cartridge 1. Never operate the spa without the filter cartridge in place.
Air Injection Venturi Adjustment Air injection into the jet’s water stream is adjusted by turning the venture dials. Each dial is independent and controls about half of the jets, respectively. Turn them counter-clockwise to increase, and clockwise to decrease, the amount of air injected into the jets’ water stream. Waterfall Flow Adjustment Turn the dial counter-clockwise to increase, and clockwise to decrease, the amount of water flow of the waterfall.
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. The 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.
Freeze Protection DO NOT ALLOW THE SPA TO FREEZE Caution, any damage caused by improper winterizing will void the warranty. You may want to 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, until it reaches your desired water temperature. Once desired water temperature is reached then you can control the functions with the buttons on the top control. For example: On the initial startup the spa will run for up to 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 Replace or clean filter cartridge. Pg. 15 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.
