Care and Maintenance
How to make your hot tub winterproof (not in use for at least six weeks)
If you are planning on not using your hot tub for six weeks or more or if no one can look after the hot tub on a weekly basis, then you should make it winterproof. Proceed as follows:
WARNING: Prior to winterising your hot tub, you will need to shock dose the hot tub water as per the instructions in the Water Chemistry section. This procedure will help prevent the growth of bacteria, algae and fungi in any areas of the piping that may not be fully free of water after you have drained your hot tub in order to shut it down for a longer period of time.
Step 1: Drain the water.
Step 2: Remove the drain plug from the pump(s) and loosen all PVC pipe connections. Then open the pump vent valves in the equipment compartment. Tighten the drain plugs again, attach the connections and/or close the vent valves only after you start using the hot tub after winter again.
Step 3: Clean the entire hot tub.
Step 4: Remove and clean the filter cartridge(s). Let the filter dry fully and then keep in a dry place.
Step 5: Secure the hot tub cover with the tie-down and locking systems. In areas where heavy snow is expected, place a large piece of plywood (or similar) on top of the hot tub cover to help support the cover against the added weight of the snow. Remove snow off the cover following each snow storm.
WARNING: To avoid water from becoming trapped between the base suction nozzle and the filter pipe, close the shim valve in front of the pump that leads to the filter. Use a wet-dry vacuum cleaner to remove the remaining water out of the pipe by placing the vacuum cleaner end over the filter hole. In a two-pump hot tub, first remove one filter and then vacuum out the water. Or pour 4.5-9 litres of RV antifreeze into the filter hole.
NOTE: RV antifreeze is non-toxic and does not need to be emptied prior to restarting the pool.
Restarting the hot tub after winter
To start using the hot tub again after a long period of non-use, simply reverse the winterisation procedure. Refill the hot tub to the water level mark.
WARNING: After refilling the hot tub, the new hot tub water needs to be shock dosed. Instructions can be found in the Water Chemistry section.
Low use or no use of the hot tub over a longer period
There may be certain times of the year when you rarely use the hot tub. For these low-use or no-use periods, please proceed as follows:
No or low use for less than two weeks
No need to make any changes.
No use for two to six weeks
If the hot tub is not going to be used for at least two weeks, then lower the temperature to the lowest setting (26 °C) or set the sleep mode. Lowering the temperature will cut the operational costs. However, you will need to increase the temperature setting again about 4 hours before use in order to heat the hot tub to 38 °C.
IMPORTANT: During all low and no-use periods, make sure you maintain the hot tub water as per the instructions in the Water Chemistry section.
NOTE: For all no-use periods, make sure that someone visually checks that the hot tub is functioning correctly and to also maintain the hot tub water as per the instructions in the Water Chemistry section. Not doing so may lead to corrosion, staining and/or lime residue on the hot tub and its technical equipment. During periods of frost, a hot tub that has malfunctioned may be subject to damaged piping or equipment as a result of ice build-up within the hot tub. If the hot tub cannot be checked and maintained on a weekly basis, then consider making the hot tub winterproof.
In regions where the temperature can fall to -15 °C, we recommend attaching a 5 cm thick insulating board or cover on the back of the equipment compartment door.
IMPORTANT: When the outside temperature reaches 15.6 °C during the day, then this insulation has to be removed in order to prevent the equipment from overheating.
Cleaning and protecting the headrests
Clean all headrests regularly with mild soap, water and a clean cloth. Treat the headrests once a month with a non-petroleum-based product as recommended by your Villeroy & Boch dealer to maintain its resistance and lustre. NOTE: Headrest discolouration is a result of improper chemical water treatment and is not covered by the Villeroy & Boch guarantee.
Vacuuming the hot tub
Debris from wind, trees and users will occasionally accumulate on the bottom of the hot tub. The filter system will remove smaller particles of dirt, but large or severe soiling has to be removed with a hot tub vacuum cleaner. Should you not have one, please get in touch with your authorised Villeroy & Boch dealer.
Although basic care instructions are provided below, it is important that you refer to the information that came with the cover. The manufacturer provides detailed information on how to look after your hot tub cover and what to do to protect its guarantee.
WARNING: A non-secured or improperly secured cover may pose a safety threat to children and may also cause damage or injury, e.g. if blown off by wind. Always remove the entire cover before using the hot tub.
IMPORTANT: Do not stand, sit or place any item on the cover that could damage it. Carefully remove any snow when higher than 5 cm. Only use cleaning agents recommended by the manufacturer. Always secure the cover with all of the fasteners when not in use, no matter whether the hot tub is empty or full of water. Please make sure that you always follow the cover care instructions when shock dosing your hot tub (see “Shock treatment”).
Cleaning the hot tub cover
Clean the hot tub cover at least once a month.
Step 1: Remove the cover and lay it down on a flat, clean surface near a garden hose.
Step 2: Rinse the cover to remove any loose debris.
Step 3: Clean the top (vinyl) of the cover with a mild washing-up liquid and a soft bristle brush. Using a gentle circular motion, scrub the cover, being careful to not let any of the cover dry before rinsing with water.
Step 4: Rinse the cover thoroughly and dry with a clean cloth.
Step 5: Use saddle soap (never a petroleum-based product) according to the manufacturer’s instructions to condition the cover.
Step 6: Wipe and rinse any dirt from the bottom of the cover.
Step 7: Replace the cover and secure the fasteners.
NOTE: To remove tree sap, use lighter fluid. Use sparingly. Apply saddle soap to the area immediately.
The EternaWood™ panelling components have been designed to provide many years of maintenance-free use. Use a mild washing-up liquid for normal cleaning. To find out more about how to remove stubborn stains, contact your authorised Villeroy & Boch dealer.
If the chemical water treatment has been neglected over a longer period of time, all of the water might have to be replaced and the back of every JetPak™ cleaned. To do so, use a soft bristle brush and a hot tub surface cleaner. Any dirt that might have accumulated on the back of each JetPak™ will have to be removed carefully. You will find more information on how to clean the acrylic surface of the JetPaks™ under “Hot tub care”.
For normal cleaning, use mild washing-up liquid or a window cleaner. Treat stubborn stains with a mild liquid cleaner or a mild detergent. Apply these cleaners with a soft, damp cloth or sponge. Rinse well and dry with a clean cloth. To find out more about how to clean hard water stains, remove light scratches and protect your hot tub, contact your authorised Villeroy & Boch dealer.
Cleaning the scum line
It is perfectly normal for oils, lotions and hair products to build up on the surface of the water over time and then leave a scum line around the perimeter of the hot tub. This can be easily removed by using a hot tub surface cleaner or a similar product. Avoid using cleaning agents that leave soap residue in the water.
WARNING: Never allow your hot tub surface to be exposed to alcohol, acetone (nail polish remover), nail polish, dry cleaning solution, lacquer thinners, petrol, pine oil, abrasive cleaners or any other household chemicals other than those listed above. Using these chemicals can void the guarantee.
On the front of the ozone cleaner (optional) is an indicator light. To check if the ozone cleaner is working properly, make sure that this indicator light goes on when the filter pump has been operating for a while after it was automatically turned on.
IMPORTANT: The indicator light won’t go on when a jet key has been operated manually. The light will then remain turned off for 30 minutes.
NOTE: If the indicator light doesn’t turn on during the automatic filter pump operation, then please contact your authorised Villeroy & Boch dealer.
To replace a faulty lamp or LED, proceed as follows:
Step 1: Turn off the power switch (in the fuse box).
Step 2: Remove the equipment compartment door, behind which you will find the technical aggregates.
Step 3: Establish where the back of the lighting unit is.
To replace standard lamps:
Step 4: Hold the lamp socket (on the back of the lighting unit) and turn anti-clockwise to take the lamp out of the lighting unit.
Step 5: Pull the lamp out of the socket while holding it straight. Step 6: Replace the lamp and reinsert the lamp socket.
To replace LEDs:
Step 4: Insert a small, standard screwdriver into the marked slit (see arrow).
Step 5: Gently loosen the back cover of the lighting unit.
Step 6: Pull out the LED component, keeping it straight. Replace the LED. Reinsert the back cover of the lighting unit.
For both lighting systems:
Step 7: Remove the equipment compartment door.
Step 8: Restore power.
NOTE: With regard to alternative lighting systems, please contact your authorised Villeroy & Boch dealer.
We recommend cleaning the filter cartridge(s) every 1 to 2 weeks or as required. Replace the filter cartridge(s) every 1 to 2 years or as required. Only use original Villeroy & Boch cartridges to not void the guarantee. To clean the filter cartridge(s), proceed as follows:
Step 1: Put the hot tub in stand-by mode.
Step 2: Remove the FilterCap™ filter cover.
Step 3: Take out the cartridge(s).
Step 4: Use a garden hose with a nozzle or another high-pressure device to clean the cartridge(s). Work on each pleat from top to bottom.
- To remove accumulated sun cream or body oil residue, soak the cartridge(s) in warm water with a filter cleaner.
- To remove limescale, soak the cartridge(s) in a plastic container using a 1:10 ratio of hydrochloric acid to water solution.
- Lime residue indicates a high pH value of the hot tub water, which needs to be corrected.
Step 5: Reinsert the cartridge(s) and refit the filter cover.
Step 6: Press any button to reset the control system.
IMPORTANT: Using a brush to clean a filter cartridge may damage the cartridge.
