Installation and Initial Start-Up Instructions
28
Once the hot tub is in its final location perform the following steps to begin the start-up procedure.
1. Consult the specification sheet for your specific hot tub model to locate the electrical spa pack. Remove the cabinet
panel exposing pack for electric connection completion.
2. 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 hot tub 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 right.

3. Inspect the hot tub for any dirt or particles that may have fallen onto the surface after
Pump Union
the plastic was removed from the unit. Wipe the hot tub with a soft damp sponge.
4. Ensure your water source is safe for hot tub use. Water may contain minerals that could
cause stains or deposits. Water with high mineral count may discolor the water once a
sanitizer is added.
5. Let the water run out of your garden hose for several minutes before filling the hot tub spa. This will flush out
stagnant water possibly harboring bacteria.
6. Begin filling the hot tub. We recommend filling the hot tub to approximately the pillow bottom. During the filling
process periodically check the unions to ensure they are tight and no water is leaking out.
7. Once the hot tub is filled, turn the circuit breaker on. The spa will turn on and start the circulation pump.
8. It may be necessary to bleed air from the pump or pumps on your spa, if after start up your 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
hot tub. This is not a service covered under warranty. To relieve an airlock situation, turn the pump off, loosen the Ultra
Massage Selector™ (diverter) by removing the handle, loosen top by turning counter-clockwise. You may possibly hear
air come out when it is loosened, after a few seconds tighten. 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 operation.
10. Refer to Control section for heating, filtration cycles and function for the model / series of your hot tub.
11. Adjust water chemistry according to the instructions provided in water chemistry guidelines section.
12. View current water temp on the control panel and set to desired level. Water will heat approximately 4-5 degrees
an hour. Times may vary.
13. Adjust water chemistry according to the instructions provided in water chemistry guidelines section.
14. Remove the hot tub cover from the box and place it on the unit. Pull down one of the straps on the hot tub cover.
