Important Safety Instructions
In addition to the Safety Instructions found in this manual, these warnings have
been assembled to help you enjoy the use of your Roto Spa hot tub. Reading and
understanding these warnings will allow you to reduce the risk of causing
inadvertent damage to your Roto Spa hot tub, your surroundings, or yourself.
Read these warnings carefully.
? The water level must be maintained at 6cm above the skimmer height. Do not let
the water level fall below the height of the skimmer level. If the water level falls
below the skimmer level this air will enter the system and may result in an
overheat situation and void the warranty.
? Always turn off your Roto Spa before draining and filling process.
? Maintain proper water pH (7.4-7.6), to high a pH level can damage the heater and
? Never use an extension cord to connect the Roto Spa to the power source.
Using an extension cord will void your warranty.
? Do not operate without an approved ground fault circuit interrupter. This
safety device shuts off the power immediately in the event of an electrical
? Install the Roto spa only on floors or areas that can withstand repeated exposure
to water. Splashing, dripping, filling and draining are routine operations, which
spill water. Equipment failure may also cause substantial water spillage. If located
in a multiple floor structure, objects on the floor below should be protected in the
event of a major spill.
? Certain objects reflect and concentrate the sun’s rays. Close proximity of the Roto
Spa cover to such objects should be avoided or damage may incur.
? When changing the water or storing the Roto spa do not leave in direct sunlight.
This may cause damage to the shell of the Roto spa.
? Do not open the controller. There are no user serviceable parts inside. Opening
the control unit will void the warranty.
Before selecting a site, please read the Safety Information, Manufacturer’s Warnings and the relevant indoor/outdoor sections.
Your Roto Spa is completely self-contained and portable. It can be set up on a patio, deck
or even indoors.
The dimensions of your Roto spa are 33” (84cm) high X 78.5” (199cm) wide.
1. Structure: The Roto Spa should always be placed on a structurally strong,
relatively smooth and level surface.
2. Drainage: do not place the Roto Spa in an area where water will puddle around
3. Electrical: Allow easy access to the controller situated behind the access panel
for electrical hook up.
Your Roto Spa is totally self-contained and portable. You can place it just about
anywhere you wish; on any smooth surface (tile, concrete, wood, and brick). Verify the
tub is placed on a firm, level well-drained base prior to set-up. If you need to step on
grass or dirt to enter the Roto Spa, we recommend the use of stepping-stones to reduce
the amount of dirt and debris entering the tub.
ANY DAMAGE CAUSED BY THE SPA RESTING ON AN UNEVEN SURFACE WILL NOT
BE COVERED BY THE WARRANTY.
When considering an installation site, always allow for easy access to your equipment.
The installation site should also allow enough room to completely remove and store the
spa cover during used.
Water splashing on the floor during use may cause a walking hazard and/or structural
damage unless good drainage is provided. Proper building materials must be used in the
area surrounding and beneath the tub. Take into consideration the room humidity, which
will exist due to high temperatures. Providing natural or forced ventilation in the room
will help maintain comfort and minimize moisture damage to the surrounding
environment. Consult an architect for aid in designing your indoor Roto Spa room.
Note: Using your spa for 15 to 20 minutes gives off the same moisture/condensation as a
15 to 20 minute shower, so a proper bathroom fan should be installed.
As a homeowner, it is your responsibility to provide a suitable, level foundation for your
Roto Spa since the delivery crews are not equipped to level or prepare sites.
Keep in mind that placing the spa on grass or dirt may increase the amount of debris that
is inadvertently brought into the spa water on users’ feet.
Caution: Your Roto Spa is not intended to be installed below ground level.
You must know the deck’s maximum load capacity to be certain you deck can support you spa. Consult a qualified building contractor or structural engineer. Your Roto Spa
when filled with water has a maximum weight of 3300 lb or 7260 kg.
Your Roto Spa comes ready to install using an 110V 15amp corded connection complete
with an inline GFCI ready to plug into a dedicated 15amp household circuit.
Roto Spas have been designed to meet the maximum safety requirements to prevent
electrical shock. Improper wiring may cause electrocution, risk of fire, risk of injuries,
and damage to the equipment. Never use an extension cord to connect the Roto Spa to the
Starting Your Roto Spa
Caution: The control module must never be operated without water in the Roto Spa;
serious damage to the heater and/or pump may result.
NOTE: Never fill your spa with soft water. Soft water makes it impossible to
maintain the proper water chemistry and may cause the water to foam.
After your Roto spa has been positioned follow these instructions for start-up.
The same steps apply each time the Roto Spa is emptied and refilled:
1. Ensure electrical power is off.
2. Do not connect power to an empty spa. Power to the Roto Spa automatically
activates the electrical equipment. Serious damage to the equipment components
may result and this is a non-warranty component failure.
3. Begin filling the Roto spa with water. The use of hot water is acceptable and will
reduce the heating time to the set point. When using this method you should first
add 30mm of cold water. Filling the Roto spa in stages will allow your hot water
tank to recover.
4. Every Roto Spa has been tested during the manufacturing process to ensure
functionality, performance, reliability and complete customer satisfaction. As a
result a small amount of water may have remained in the system after testing. Clean
the interior of the Roto Spa of any remaining debris. Completely wipe the interior
of the Roto Spa with a wet sponge or a soft rag. For added cleaning you may use an
isopropyl alcohol such as Windex.
5. Before filling your spa for the first time, remove the pump compartment door,
check to ensure that the unions on either side of the pump and heater units are hand-
tight and the water valves are fully open. Remove the filter lid and skimmer basket.
Then insert the end of a garden hose into the filter canister and begin filling the spa
to the recommended level. The water level of the spa should be approximately 3cm
above the highest jet in the spa and at least 5 to 8 cm over the skimmer/filter
opening. Low water levels can cause damage to the pump and heater unit. Check all
connections for leaks and hand tighten union fittings as required. The equipment
may shift slightly during transportation.
6. Reinstall the skimmer basket and filter lid once the spa is filled and check to ensure
that the filter is installed correctly.
7. After the spa has been filled with water (and only when water level is adequate to
avoid pump damage) power up the Roto Spa. When the spa is powered up, the
electronic system will automatically activate and in the first few seconds of power-
up the system will be in auto diagnosis mode, checking the power levels (voltage
correctness of wiring fuses etc.) At the end of the first step, the temperature of the
water will be displayed and the system will begin the heating process. NOTE: Do
not expect to feel hot water immediately coming from the jets. The highly efficient
heaters are designed to provide cost-saving, low level heating. The expected time to
reach the set point depends on initial water temperature and ambient temperature.
8. The default set point water temperature is 95F. You can raise or lower the water
temperature by pressing the “(??)” button on the control panel to the desired
9. Pump key is used to turn pump on or to select between off, low and high speeds.
Press Pump key to turn pump on. A second press will change pump speed.
A built-in timer will turn pump off 20 minutes after it has been started unless the
user does so manually.
The “Pump” indicator lights up on keypad display when pump is on.
