• The installation of the hot tub must be planned on a case-by-case basis.
• The manufacturer does not offer detailed ready plans.
• REXENER hot tub kits are compliant with the EN 17125 standard’s installation method concerning hot tubs installed on the ground outdoors.
• The estimated installation time of REXENER hot tub kits is approximately 3 hours.
• The hot tub should be filled according to the number of users and considering the maximum filling volume (ca. 1,500 l).
• If the heating device (wood stove/REXENER PR200 water heater) is not in use, the water must be emptied from the heating device.
• In winter use, it is especially important that there is no water left in the system, as this could cause damage.
• The warranty of the manufacturer and importer does not compensate for damage caused by freezing.
• The use of an insulation cover speeds up healing and decreases water evaporation on the water surface.

PREPARING THE BASE

• The base of the hot tub can be built with gravel or crushed stone, for example.
• A well-rammed bottom is the best base for a hot tub.
• Frost insulation can be installed on the base. This way, the earth cannot move, and the hot tub stays firmly in place.
• It can be good to place concrete stones under the hot tub and frame, for example. When installed this way, the bottom frame of the tub and box is left slightly above the ground, and the air also circulates under the frame.
• The wood stove (REXENER Silence) and the protective case containing technical parts (REXENER Aurora/Polar) must be installed on an even surface, and at the same level as the hot tub kit frame’s bottom.
• The base must be able to carry ca. 2,500 kg.
• When choosing the location, consider the possibilities for emptying the tub.

EMBEDDING THE HOT TUB ON A TERRACE

• If the hot tub kit is embedded in the terrace, the specifications in this instruction manual and the EN 17125 standard must be given special attention.
• All REXENER hot tubs can be embedded in a terrace as desired.
• When embedding a tub, take into account that the base for the hot tub kit has been designed to an appropriate height.
• The borders of the hot tub must remain at least 15–20 cm from the terrace’s surface. When installed this way, the edges of the insulation cover have enough room to fit in place.
• The hole made in the terrace must be at least 1,900 x 1,900 mm to allow the hot tub to fit easily into place.
• When embedding a REXENER Silence hot tub, the space needed for the woodstove must be considered.
• The wood stove must be separated from the terrace’s wooden parts, and safety distances must be taken into account.
• In connection with REXENER Aurora/Polar hot tubs, take into account the protective case that is assembled on the hot tub’s side. The bottom of the protective case must be at the same level as the hot tub’s base. Safety distances must also be observed when installing the protective case.
• When embedding the product in a terrace, it is very important to ensure that there are no access obstacles for servicing and heating the protective case (REXENER Polar/Aurora) and wood stove (REXENER Silence).
• Take into account the installation of hoses used for draining the hot tub and the access to the eventual draining tap.

REMEMBER SILENCE, INSTALLATION INSTRUCTIONS

Installation of the woodstove

• The stove must be installed on an even surface, and at the same level as the hot tub kit frame’s bottom.
• The upper return water hose must be ascending seen from the stove, whereas the lower suction hose must be in a horizontal position or at a slightly descending angle in relation to the feedthrough.
• If necessary, the rubber hoses delivered with the hot tub kit should be shortened as appropriate.
• The free circulation of water must not be closed because of pressure accumulation.
• It is also recommended that concrete slabs, for example, be installed under the frame and stove to improve air circulation.
• Make sure that the heating device has been completely filled with water before you start heating

Smoke pipes of the woodstove

• The smoke pipes included in the hot tub are made of stainless steel. The package includes 2 x 1,000 mm interconnectable smoke pipes. One of them has a pipe hat. The smoke pipes are installed inside each other by the seams and placed on top of the stove’s smoke hole.

OPERATING INSTRUCTIONS FOR ACCESSORIES

LED pool lights (REXENER Aurora/Polar)

• REXENER Aurora and Polar hot tubs are equipped with pool lights. The RGB pool light is adjusted with remote control.
• The hot tub has no separate button to control the lights. The lights are turned on and off by pressing the remote-control button.
• You can leave on only one light or use several pre-programmed color programs by operating the remote control.
• The remote control must not be touched with wet hands, because it is not water-resistant.
• The remote control should be stored in a warm place indoors.
• The electric cord of the LED light is connected to the socket in the protective case

Whirlpool bath kit (REXENER Polar)

• REXENER Polar is equipped with a whirlpool bath kit.
• The switch, pump, nozzles, and electric cord of the whirlpool bath kit have been pre-installed. The pump and electric cord of the whirlpool bath kit is located inside the frame, close to the edge on the box’s side. From there, it is easy to connect them to the pre-installed socket in the box.
• The button of the whirlpool bath kit is installed at the pool’s edge, on the side of the step
• The whirlpool bath kit is turned on and off by pressing the button located on the pool’s edge.
• The electric cord of the whirlpool bath kit is connected to the socket in the protective case

Please note!
REXENER Polar hot tubs are equipped with whirlpool bath kits. Water can remain in the pipes of whirlpool bath devices, even though the pool is emptied. The water does not drain from the piping on its own. The whirlpool bath device must be turned on when draining the pool after the water surface is below the whirlpool nozzle. This way, whirlpool bath pipes are completely emptied of water, and the problems and damage caused by the eventual freezing of pipes can be avoided.

OPERATING INSTRUCTIONS FOR THE WOODSTOVE (REXENER SILENCE)

Before heating

• The pool must be filled to 5 cm above the uppermost stove feed through before you start heating. If the stove heating is started, and the stove’s water container is not full of water, the stove will melt and may cause serious injuries in the worst case.
• Ensure that the pool is empty, and the bottom valve and/or plug are closed before you start heating.
• Also make sure that the water circulation in the stove has not been blocked or closed before you start heating.
• Check that the attachment points between the stove and pool are not leaking. If you detect a leak, the connections must be tightened enough to stop it.
  Please note! The use of a wood stove takes practice and the right healing method to achieve the best result.

General instructions for heating a wood stove:

• Do not use lighter fluid to ignite the wood
• The wood to be burned should preferably be in small pieces
• Do not use wood containing nails or construction waste in the stove. The aluminum stove does not tolerate hot metal objects, and they will damage the stove
• Adjust the airflow with controls so that it is continuously strong
• When heating cold water and a new stove, some water may come out of the front corners. This is condensation water, and it will stop when the stove has been used a few times.
• Mix the water in the pool during heating to achieve an even temperature.

Draining the wood stove and pool

• Empty both the pool and stove of water.
• Open the stove’s drainage plug at its front corner, and open the pool’s drainage valve and plug.
• The stove’s fire must be extinguished and cooled down before drainage to avoid dangerous situations and damage.
• The cover of the pool should be left slightly open to avoid a vacuum in the pool.
• If the stove is stored in freezing temperatures, make sure that all the water has been drained from both the stove and hoses.
• The fireplace of the stove must be cleaned after use. For cleaning, use products appropriate for cleaning heated surfaces, such as oven cleaning agents or similar cleaning products.

Maintenance of the woodstove

The water jacket of the stove must be cleaned regularly to remove eventually accumulated dirt. The water jacket can be cleaned using the stove’s upper feed through by flushing with a water hose, for example.
The stove’s smoke pipes must be sooted on a regular basis, ca. 2 to 3 times each year.
The grates used in the stove get worn down in use, and they must be changed. Check the condition of the grates before heating. If you want to buy a new grate for the stove as an accessory, you can find up-to-date contact information at www.rexener.com.

OPERATING INSTRUCTIONS FOR THE REXENER PR200 WATER HEATER (REXENER

AURORA/POLAR)

Before heating

• Before filling the pool, make sure that the pool is empty, and the bottom valve and/or plug are closed.
• Ensure that the draining tap/plug of the REXENER PR-200 water heater and REXENER circulation pump is closed.
• Ensure that the water circulation of the REXENER PR200 water heater and Rexener circulation pump has not been blocked or closed before you start heating.
• Check that the attachment points between the heater and pump and the pool are not leaking. If you detect a leak, the connections must be tightened enough to stop it
• The pool must be filled, or at least the leg space must be filled to the lower rim of the seat before starting the heater/pump.
• Fill the fuel tank with biodiesel, diesel or “red diesel” before start-up
• The REXENER PR200 water heater is started by pressing the start button. To regulate the temperature, use the arrow buttons.
• The maximum temperature is 45 degrees Celsius.
• The recommended bathing temperature is 37 to 39 degrees.
• Detailed instructions for the Rexener heater and the Rexener filter and pump can be found in the manual section that covers device operating instructions, or in the separate manuals for the heater and pump.

CLEANING AND MAINTAINING THE HOT TUB

The glass fiber pool must be cleaned and dried whenever possible, such as when the pool is empty.
After use, the pool must be flushed thoroughly. If pool care products such as chemicals are used in the pool, the water’s pH must be monitored closely to avoid damage.

Treating the surfaces of glass fiber pools

We recommend that REXENER hot tub pools be cleaned thoroughly once per year. Detergents suitable for plastic surfaces can be used for cleaning. Edges and surfaces should be cleaned with a damp cloth. When necessary, stuck dirt can be removed from pool surfaces with a magic sponge, for example. Abrasive materials must not be used.

• The water must meet swimming water criteria, the pH value must be correct, and the chemicals must be dosed in accordance with instructions.
• In normal use, there is little need for maintenance.
• If the gel coat surface requires polishing or grinding, devices/products intended for boat care are suitable for treating the surfaces.
• Contact the manufacturer’s maintenance service if necessary.

The Gelcoat color codes for the pools:

• Gabro black (dark grey) Gelcoat RAL7021
• Arctic White (white) Pool color SW P10616 S
• The warranty granted for the pool does not cover faults caused by erroneous use, such as corrosion of the pool or its accessories, or surface damage. You can find the detailed warranty terms at www.rexener.com
• When emptying the pool, the water must be directed into the appropriate waste-water system. When using chemicals, the water must be drained to the sewer to prevent contamination.

Treatment of wood frame surfaces

Oiled spruce panels retain their color well, but it is recommended to repeat the surface treatment according to need..
Hottubs are manufactured using Rexener Gray, a shade of gray-tinted separately for Rexener products, to which a wood preservative has been added. You can purchase the original color from your nearest Recent dealer or the Rexener online store. With the original Rexener paint, you ensure the best possible durability of the wood frame in all conditions and the shade is the same as the original. If you wish, you can also use another paint suitable for treating wood cladding surfaces. In general, the most common wood oils and translucent dyes, both water-based and solvent-based, are suitable for this. Always make sure the product is suitable for the surface to be treated first and test it on a  small area before treating the entire pool. The warranty does not cover defects caused by the use of the wrong type of treatment agent.

WINTER USE INSTRUCTIONS

Rexener hot tub products have been designed for tough Northern conditions. Hot tub kits are frost-proof when used and maintained correctly.

Correct use of the drainage valve in winter
During winter use, it is important to keep the pool’s drainage pipe empty, so that it does not freeze. When you use the pool’s bottom plug, the drainage pipe remains empty, and the problems caused by freezing are thus avoided. When drainage pipes are equipped with a drainage valve, it is important to keep the drainage valve open or at least 45 degrees in the open position during the winter. If the drainage valve is closed, water can remain inside the drainage valve and pipe, causing damage when it freezes. A pool bottom plug must be used in all hot tub versions.

Winter storage of heaters

• Drain the pool and heating devices with pipes completely
• Cover the pool and accessories so that they do not touch snow and ice directly.
• Keep the plug delivered with the pool for later use.
• Ensure that snow does not accumulate in the support frame or pool of the hot tub kit.
• PLEASE NOTE! THE WARRANTY DOES NOT COVER DAMAGE CAUSED BY FREEZING

Using heaters in winter

The hot tub kit can also be used in winter. Model-specific differences and precautions must be observed .during winter use.
In winter use, it is important to consider especially blocks caused by freezing in the water-flow channels.
Please note! Water must not be allowed to freeze in either heating mode (wood stove/REXENER PR200 water heater). Maintain the water temperature so that it does not freeze.
The wood stove (REXENER Silence) must not be used if ice is detected in the water-flow piping or stove, and water cannot circulate normally. If you notice that the water flow channels are frozen, the stove should be removed and taken to a warm space to thaw.
The REXENER PR200 water heater (REXENER Aurora/Polar) is excellent for winter use. The most important thing is to ensure that the flow channels are not blocked, and water flows normally.
If you notice that a flow channel has frozen, it must be thawed before starting the pump and heater.
During winter use, it is recommended to add enough warm water into the pool to open the pump and flow channels and allow water to flow freely in the piping.
If the circulation pump freezes, it can be started by pouring 1 L of warm water into the circulation pump.
After this, the pool can be filled with water normally. You can maintain the water temperature at ten degrees, for example, and heat the water quickly to an optimal bathing temperature.
