When you are first filling up your hot tub, your topside control panel may flash with the message IC , which normally indicates that a potential ice condition is detected. As the water is probably very cold, this won’t be an issue, and should go away once the spa has heated up past 45°F/7.2°C
undo all the unions on the pumps and wait for a thaw. You could try running a hose into the spa and let it overflow, if it is in a position for that. If your lucky and you don’t need a site visit, fill it up. Hot tubs fitted with a Balboa control system have a built in freeze protection
If the spa will not be used for extended periods in a location where there is likelihood of below freezing temperatures, the spa should be prepared as follows:
- Shut off power
Drain spa of all water.
If spa is equipped with a blower, turn on power and run the blower for 10 seconds to clean the air channels of water.
Shut off the power
- Remove any remaining water with a sponge or wet dry Vacuum.
- Disconnect the inlet and outlet union to the Control Pack, and tilt the Pack, slightly to allow any remaining water to run out. Using a wet dry vacuum or similar product, vacuum any additional water out of the uncoupled lines, pack and pump heads.
- Remove the motors, pumps, electronics, and blowers and store them in a warm dry place to prevent moisture damaging the units. (Leave the TOPSIDE control in place and seal wire ends in plastic bag.
- Using a wet/dry vacuum, either suck water from each jet, and open line or blow water from each jet.
- Ensure Hose Bib (drain) is left open.
- Cover all open pipes from motors and control system with screen mesh to prevent debris from entering the system.
- Wrap spa/hot tub with hard cover (for added protection; cover spa with tarpaulin or Canadian Spa winter cover)
