Winterizing - PDC spas SYNERGY Series FX15 Owner's Manual

Regular Maintenance
Periodic Water Draining and Refilling
A er a certain me, you may find the addi on of chemicals will not clarify or eliminate odors in the spa. This is an indica on the
water needs to be drained and replaced. Generally, depending upon bather load and water chemistry maintenance, this may need
done every 3 months. With the use of ozone, this may need done less frequently.
1. Reduce set temperature to 59˚F (15˚C).
2. Turn off all power.
3. Connect a garden hose to the recessed drain valve found on the side of your swim spa cabinet, by slowly
pulling the cap out all the way (approximately 2") and turn cap counterclockwise to remove. A ach the hose
and push valve 1", this will start the draining process. A er draining the spa, replace the cap and push the valve
all the way in. (See photo.) Note: Unscrew the large nut around the drain valve to remove the cabinet panel
from the spa for servicing, if necessary.
4. Clean cartridge filter as noted previously in this sec on regarding maintenance recommenda ons.
5. Clean acrylic shell surface with non‐sudsing cleanser per maintenance recommenda ons.
6. Begin filling the swim spa. We recommend filling the swim spa to the top line on side wall. During the filling process periodically
check the unions to ensure they are ght and no water is leaking out. The dual zone models are separate zones each with their own
pack, heater, control. Follow the connec on, filling instruc ons for each zone.
7. Once the swim spa is filled turn the circuit breaker on. The spa will turn on and start the circula on pump.
8. It may be necessary to bleed air from the pump or pumps on your swim spa, if a er start up your swim spa pumps do not operate.
Due to the nature of water flow and hydrotherapy pumps, please be advised that air locking of pumps may occur. PDC Spas has
taken measures to reduce the possibility of this, but it s ll may occur, especially a er refilling a swim spa. This is not a service
covered under warranty. To relieve an airlock situa on, loosen the pump union on the discharge side of the pump. You may
possibly hear air come out when union is loosened, a er a few seconds ghten the union. Turn the pump on to see if proper jet
flow has been achieved. If proper jet flow has not been achieved repeat process.
9. Open air regulators allowing maximum flow through jets assuring pump opera on.
10. Refer to Waterway Neo 2100 Control sec on for hea ng, filtra on cycles and func on.
11. Adjust water chemistry according to the instruc ons provided in water chemistry guidelines sec on.
12. View current water temp on the control panel and set to desired level. Water will heat approximately 1– 2 degrees an hour.
Times may vary.
13. Close cover to expedite hea ng and assure safety. Always keep the cover locked when not in use. Keep the keys in a safe place,
out of the reach of children
Winterizing the Swim Spa
Your swim spa has been designed to be used year‐round and it is certainly suggested that you enjoy the many benefits of
enjoying your purchase in any season. If you should decide to not use your swim spa during the winter months, it must be cared
for properly to avoid damage. During those months of shut‐down, we recommend the unit being checked periodically to assure
no water is entering the unit causing poten al freezing resul ng in damage. Your warranty does not cover this type of damage, both
structural and opera onal.
1. Turn off at circuit breaker, open air controls and jets, drain completely using drain valve and sump pump if needed.
2. Remove filter cartridges and all cabinet panels to access equipment.
3. Loosen pump unions and winterizing plug from face of pump. Replace plugs a er all water has been cleared from the unit.
4. Use a shop vac in blowing mode to remove all water from return and suc on lines.
5. Use the wet vacuum to pull all water from jets. You may choose to use a non‐toxic RV type an ‐freeze to assure freeze
preven on and remove ALL prior to next use.
6. Replace all cabinet panels.
7. Cover the unit with the thermal cover, lock in place.
Storing the Swim Spa
The swim spa shell is to never be unprotected and uninsulated during storage. Never use a clear plas c wrap or it's like to cover
it. Never leave unprotected in direct sunlight as it can damage the acrylic and fi ngs, not covered under warranty. Always use the
thermal cover. Do not allow, even if winterized, the unit in cold temperatures 0°F or below. If it will be exposed to these
temperatures, keep the unit filled and set to the lowest opera ng temperature se ng.
