Dimension One Spas – @Home Series Owner’s Manual

Special Cold Weather Instructions
All Dimension One Spas are designed for year-round use. They are insulated for energy efficiency and to protect the
plumbing and equipment when the spa is operational. The spa has a freeze protection mode to circulate water during
freezing weather, assuming the spa has electrical power and the proper water level. Therefore, keeping your spa
operational is your best defense against freeze damage.
If you find it necessary to drain your water during the winter months, in an area where freezing conditions may exist,
please follow all of the Winterizing instructions below to minimize the risk of freeze damage. Failure to complete any of
the steps will increase the chance of damage, as small amounts of water trapped in pipes will expand as it freezes, and
may damage your plumbing lines or fittings.
Dimension One Spas recommends that you do not drain your system for the winter. Freeze damage
caused by draining or Winterizing your system is specifically not covered by your warranty.
Items Required for Winterizing
• Phillips head screwdriver
• 16” (40.6 cm) Channel-lock pliers
• High pressure air blower
• Commercial grade wet-vacuum
• Protective goggles
• 3 gallons (11.37 liters) to 6 gallons (22.74 liters) of Non-Toxic, Swimming Pool or Recreational Vehicle
Drinking Water Antifreeze
• Strong, able-bodied people capable of lifting the spa into upright position
• Enough time (and patience) to perform all steps.
Procedure for Winterizing
1. Shut off the power to the system and make sure that it cannot be accidentally turned back on.
2. Remove filter elements from filter assembly.
3. Drain water from the system using the drain fitting and garden hose, or a submersible pump.
4. Open the equipment compartment and locate pumps and heater.
5. Remove all of the drain plugs from each pump.
6. Loosen the unions on both sides of each pump, and on the heater if applicable.
7. If your system has a Dynamic Jet Sequencer, please remove that access panel as well and loosen all unions on
each of the sequencer valves. There are 6 sequencer valves, so you need to loosen 12 unions.
8. Tip the entire spa up onto one side (not the equipment bay side or the opposite side). The system will have
some water remaining, which will add to the weight. Be sure to have enough people available to safely lift the
weight of your spa.
9. Close all jets, by turning the jet faces counter-clockwise.
10. Put on goggles to protect your eyes from air, water, antifreeze or debris exiting the jets or drains.
11. Insert the hose of a high-pressure air blower into the filter-element fitting. Some models may have 2 filters.
Begin with the left-hand filter fitting, which will help evacuate water from the circulation pump system. Then
proceed to the right-hand filter fitting. When using air blower on single-filter systems or the right-hand fitting
on dual filter systems, rotate each of the jet faces clockwise to open it, and then counter-clockwise to close it
after blowing that jet. Do this to each jet, one jet at a time. Be careful, as water will be coming out of each jet
fitting as you blow it out. Perform this operation until no more water is coming from the jets.
