Installation and Initial Start-Up Instructions
30
Once the swim spa is in its final location perform the following steps to begin the start-up procedure.
1. Locate white lines painted on the outside of the swim spa base. There are as few as 8 and as many as 14 depending
on the model and series. Insert provided composite shim below the painted line, between
the swim spa base and foundation. Push shim in by hand until it stops, then gently tap shim
with hammer until it stops. Score shim with utility knife and break off flush with swim spa
base. Photo top right.
2. Consult the specification sheet for your specific swim spa model to locate the electrical
spa pack. Remove the cabinet panel exposing pack to complete electric connection.
3. Consult the specification sheet to locate all the pumps for your specific model, then
remove appropriate cabinet panels. Be sure all pump and heater unions are secure. Each
pump has 2 unions, the heater has 2 unions. The unions of a newly delivered swim spa may
have loosened during transportation. While checking the unions also check the slide valves
are in the up position and the lock is installed. Photo bottom right.
4. Inspect the swim spa for any dirt or particles that may have gotten on the surface after
the plastic was removed from the swim spa. Wipe the swim spa with a soft damp sponge.
5. Ensure your water source is safe for hot tub use. Water may contain minerals that may
cause stains or deposits. Water with high mineral count may discolor the water once a sanitizer is added.
6. Let the water run out of your garden hose for several minutes before filling the swim spa. This will flush out stagnant
water in the line that may cause bacteria.
7. 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 tight and no water is leaking out. The dual zone models are separate
zones each with their own pack, heater, control. Follow the connection, filling instructions for each zone.
8. Once the swim spa is filled turn the circuit breaker on. The spa will turn on and start the circulation pump.
9. It may be necessary to bleed air from the pump or pumps on your swim spa, if after 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 still may occur, especially
after refilling a swim spa. This is not a service covered under warranty. To relieve an airlock situation, loosen the
pump union on the discharge side of the pump. You may possibly hear air come out when union is loosened, after a
few seconds tighten 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.
10. Open air regulators allowing maximum flow through jets assuring pump operation.
11. Refer to Control section for heating, filtration cycles and system operation.
