Question: Why do we keep getting the HL code on the pad even though the tub is not hot yet. After a clean and refill we turned it on and still get the HL code.

Answer: The HL code can be caused by the PC board, Sensor, or Heater. Most often cause is the PC board or sensor. In order for the heater to cause this error it has to be bad and no GFCI or bad GFCI installed in the electric. If you have a GFCI breaker installed and it trips when you push the test button then it is the board or sensor. The only way to tell is to plug a new sensor into the board and see if it works.

Question: How long does it take to heat the water in the tub?

Answer: Here are the caveats:

1. Ambient Temperature (if it is colder outside, it takes longer to heat the tub)
2. Cover In Place (it will take longer if the cover is off - keep the cover on while heating the water)
3. All components are in good working condition

The spa will heat between 3 to 6 degrees per hour.

Question: Can I use Hydrogen Peroxid (H₂O₂) to sanitize my hot tub?

Answer: The use of Bromine or Hydrogen Peroxide as a sanitizer is NOT recommended.

Using Hydrogen Peroxide Voids the Nordic Warranty

Question: Some swimming pools use salt water and sodium bromide - do you recommend this for your hot tubs?

Answer: We do not recommend the use of Salt Water Bromide as a sanitizer. We do have hot tub cleaning and water sanitizing producedures - click to view. This procedure works very well especially with an ozonator. When used correctly the chlorine has dissipated from the water before your next use. This will help eliminate harsh chlorine odor and skin irritation.

How to Drain your Hot Tub

Question: How do I drain my tub?

Answer: How you drain your tub depends upon what you are doing with it after the water is out. 

1. Drain water to improve water quality - you are going to fill it up immediately afterwards.
2. Drain water to repair equipment (e.g. jets, pumps, ozonator, fittings, et. al.)
3. Drain the water for non-use during warm months.
4. Drain water and winterized the tub

Below are the instructions to completely remove the water in order to winterize or to perform repair. 

If you are simply replacing the water, start a syphon with a garden hose or use a tub vacuum.

THINGS THAT WILL BE NEEDED:

• 2 gallons of NON-TOXIC (R-V type) antifreeze (for winterizing only)
• a strong wet/dry vacuum (shop vac)
• a turkey-baster
• 1 or 2 light plastic bowls approximately 5" diameter
• TIME approx. 2 hours

INSTRUCTIONS:

1. Drain your tub.
2. With the wet-vac vacuum out any water remaining in the foot-well. Then with each jet in the open position, vacuum each jet nozzle until no more water comes out. DO NOT FORGET the small ozone jet in the foot-well.
3. With the vacuum over the whirlpool jet nozzle(s) and plastic bowls over the suction covers in the footwell, change it to each diverter position until there is no more water being drawn out.
4. You can apply a Teflon based lubricant (Magic Lube by Aladdin) to the gaskets on the pump, heater, and drain spigot to help avoid them from drying out.
5. Winterizing Only: Remove your filter, clean it and place in storage until you restart your tub. Pour NON-TOXIC antifreeze into the filter canister until it runs out into the foot-well of your tub through the suction covers.
6. With the turkey-baster, squirt a small amount of NON-TOXIC antifreeze into each jet. Usually the side jets will take around one ounce, and the whirlpool jet(s) will take several ounces (about 5 squirts per whirlpool jet). DO NOT FORGET the small ozone jet that is located in the foot-well of your tub.
7. Place the cover on the tub, and place a tarp over the tub and cover. Making sure to securely tie down the tarp. The tarp will help reduce the amount of weather your tub is exposed to.

A COUPLE THINGS YOU SHOULD BE AWARE OF.

When a tub is drained and left empty, o-rings and pump seals can dry out and loose their ability to seal properly. You should closely inspect for small leaks in the equipment area when you do your restart. If you are unsure of the location of the o-rings and pump seal, contact your dealer for help. If replaced early the damage caused by these failures can be inexpensive to fix.

RE-START UP:

When restarting your tub, you will want to fill the tub and run all of the jets on high speed for 10-15 minutes. This will help flush the residue of the antifreeze out of the plumbing. Then drain the tub, clean the sides with an approved cleaner, place your filter back into the filter canister, re-fill your tub and balance your chemicals. You may notice slightly more foaming than normal when you first start using your tub, this can be reduced with anti-foaming agents and generally gets better over the first week or two of usage as the filter removes the anti-freeze and organic residue left behind after rinsing and cleaning.

Make sure you check your filter at least once per week and rinse it out as needed for the first few weeks. You may also find it necessary to soak your filter in a filter cleaner after a few days, depending on the level of contaminant left in the tub after the re-start.

How to Winterize your Hot Tub

Question: How do I winterize my tub after my tubbing season is over?

Answer: While we feel that some of the best times to use your spa can be during the colder months, we understand that there can be a need for some owners to close their tubs during the winter months. We feel that winterization should be left to the professionals, but if done carefully using the following instructions your risk of damage from freezing can be minimized. Please note, we do not warrant against freezing damage in a tub that has been winterized, either by the owner of by a professional service center.

THINGS THAT WILL BE NEEDED:

• 2 gallons of NON-TOXIC (R-V type) antifreeze
• a strong wet/dry vacuum (shop vac)
• a turkey-baster
• 1 or 2 light plastic bowls approximately 5" diameter

Question: What gauge wire do I need for my tub?

Answer: The wire gauge will have to meet the local code for a 50 Amp continuous draw circuit at the distance you are running the wire.

Nordic recommends a  6 gauge wire, as long as it is big enough to meet the local codes requirements.

It must be wired on a 50 Amp GFCI circuit and requires 4 wires.

Question: What are the steps to keep my tub and the water clean?

Answer: Below is our guide to keeping your Nordic Tub clean.

Water Clarity Procedures for Nordic Hot Tubs

1 . If using “ground” or “well” water, (do NOT use soft water!) a MINERAL or METAL Gone or Out product must be used on fill-up. (this is not an inhibitor product but a “gone” or “out” product. I recommend Leisure Time “Metal Gone”. The filter may need to be sprayed for a couple days as the minerals collect in the filter (even if not visible still spray)

2 . Use ONLY a chlorine Di-Chlor granular product. When using with an ozonator, set the filtration cycle time at 8 to 12 hours a day AT FIRST. This is done on the “control panel” with a setting of either 4 or 8 indicating two 4 hour cycles or two 8 hour cycles. When the “tub” is done being used for the last time of each day it is USED, add 1-2 TABLESPOONS of the Di-Chlor chlorine. This will help the ozonator catch up to the sanitation needed and will also dissipate quickly not leaving a “chlorine” smell. Adjust cycle times according to your water performance.

3 . Each day the tub is USED, the ph must be balanced. Again this is done AFTER the last time the tub is USED for that day. A “liquid drop” test kit that tests only chlorine and ph is recommended and needed. When testing the ph, be sure to
add less than you think so if more is needed it can be added rather than “adding chemicals” to overcome “over-adding” chemicals. The chlorine test results ONLY need to show a “trace” Di-Chlor reading (if an ozonator is being used too). If
an ozonator is NOT being used, the Di-Chlor reading should be in the range indicated by the test kit as correct.

4 . From time-to-time, a “clarifier” and a “calcium inhibitor” are needed as a maintenance procedure. This is determined by the usage of your tub. The more it is used, the more “maintenance” chemicals needed.

This is a guide. Variances will occur depending on each individual situation. This guide is recommended for 45 days on which YOUR formula and procedure will come together for YOUR tub and needs. Then your tub water maintenance will be easy and care-free.

*NOTE: This becomes easier when your formula is working. A period of time is needed (as the 45 days indicates) to get this correct. Nordic Hot Tubs are made of a “poly blend” and differs from ALL the rest of the hot tubs typically on the market. Because of this advanced technology and material being used by Nordic Hot Tubs, “other” sanitation systems that require either what is said to be “no maintenance” or continual re-buying of something to get your water clear, is intended to sell more chemicals or products. Nordic Hot Tub water maintenance is economical, affordable, unique and eventually simple. This is a tried and true guide proven to work EVERYTIME in a Nordic Hot Tub!

FOLLOW INSTRUCTIONS CAREFULLY AND PRECISELY.

Question: I installed my hot tub and ran it for about a month and found out that the energy is quite large. This is going to be bigger in Winter. What can I do?

Answer: The first months bill is going to be the highest due to the cost off heating the spa from cold to the desired temp. You may also want to make sure the filter cycle is set on 2 or 3. If it is set higher it can cost more to run.

Question: I own a Bella hot tub and wanting to know how to change the light cover in the tub. Can I do this while the tub is filled?

Answer: The colored light covers press over clear lens. You should be able to remove them by hand. This can be done with the spa full.

Question: I have a nordic spa and there is a crack in the tub, can you tell me how I can seal it?

Answer: Nordic Hot Tubs hava a life time warranty. We will fix your tub and not charge you for a replacement shell or for the labor. You are required to ship the tub to us. To facilitate any warranty work, we ask the following questions:

• Have you contacted your dealer? What is the Dealer's Name?
• Are you the original owner of the hot tub?
• How long ago did you purchase the tub? Purchase Date?
• Where is the crack located?
• Can you send us a photo?
• What is the hot tub serial number?

When you purchase the tub, make sure our Dealer and/or you register the hot tub. You can register online by clicking HERE.

Question: I just bought a used 2004 Nordic Crown XL that has been sitting unused for 2 1/2 years The previous owner had taken the PVC connector off between the pump and heater to drain the tub before moving it into storage and he lost one of the rubber seals for the connection. Are the seals all the same and are they available for individual purchase?

Answer: The seals used in the fittings for the pump is different then the seals for the heater. The heater seals are part # 020004 and for the pump seals they are part # 020025.

In general, be sure to use the correct part for you hot tub - if the exact part is not used, we do not guarantee the tub will function properly.

Parts can be ordered through an authorized Nordic dealer. Click HERE to find one close to your by zip code.

Question: My spa is functioning; however, its making a strained sound when the pump is on.  I have cleaned and replaced the filter, checked chemicals, cleaned the jets, and intakes.  Im afraid its gonna blow up it sounds so loud. What should I do?

Answer: Pump noise can be caused by something stuck in the pump head, motor failure, or PC board failure. A service technician will have to be on sight to diagnose the spa.  Most commonly I see bad motor bearings as a cause of noise.

Click here to find a/your dealer.

Question: The contol panel shows "FL" - What does this mean?

Answer: FL means the tub is not sensing water flow through the heater. This can be caused by a dirty or bad filter. If replacing the filter does not resolve the issue a service technician should diagnoses the tub on sight.
