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 system is operational. The system has a “Smart Winter” freeze protection mode to circulate water during freezing weather, assuming the system has electrical power and the proper water level. Therefore, keeping your system operational is your best defense against freeze damage.

However, if there freezing conditions present and shutting down the spa for the winter is unavoidable, or where conditions may get too cold for the spa’s “Smart Winter” mode to prevent freezing, the spa should be Winterized by a professional Dimension One dealer or authorized service representative. Draining the spa will not prevent freeze damage, because small amounts of water in the plumbing can expand and damage the system.

Draining or Winterizing the spa is specifically not covered by the warranty. This is why only a professional should be allowed to Winterize your spa if it becomes necessary.

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 the 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.

12.Remove jet faces and insert the hose of a high-pressure air blower into each jet fitting. Continue this process, until no more water comes out of any jet fitting or drain fitting, and you no longer hear water gurgling within the plumbing. Place all jet faces in a plastic bag and set aside until you are ready to use your spa again.
