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.
