Initial Swim spa setup
1.
Put swim spa in final position that allows for access to equipment and swim spa components.
2.
Remove skirt panels “A” and “B” to access the electrical connections inside the swim spa.
The junction box (MP Swim Spas Only), swim spa control system(s) and majority of the equip-
ment in your swim spa can be accessed by removing access panels “A” and “B”.
Slice Valve and Pump Union
3.
Be sure all pump and heater unions are secure. Each pump has
2 unions and the heater has 2 unions. A newly delivered swim
spa may have loose unions caused in transporting the swim
spa. Check that all slice valves are open, in the up position. The
slice valves may become closed during transportation of the
swim spa.
4.
Fill the swim spa to the “minimum safe water level” sticker. This sticker is typically located
on the shell of the swim spa near the filter area. On the Momentum swim spa model with a
clear acrylic divider, it is recommended that the swim side be filled first and then the spa side.
When draining the swim spa always drain the spa side before draining the swim side.
5.
Turn on power to the swim spa. If your swim
spa is equipped with two electrical supplies,
make sure that they are both turned on. The
swim spa will go through its priming mode.
This lasts approximately 5 minutes. The pur-
pose of the priming mode is to help insure
that the jet pumps have been primed with
water and are ready to operate. It may be necessary in some instances to bleed air from the
jet pumps in your swim spa. If after the priming mode the swim spa pumps run but do not
move water, the pump may have an air lock.
Due to the nature of water flow and hydro-therapy pumps, please be advised that air locking
of pumps may occur. Master Spas has taken measures to reduce the possibility of this, but it
still may occur, especially after filling the swim spa. This is not a service covered by the war-
ranty and service charges may apply.
To relieve an airlock situation, loosen the pump union on the discharge of the pump. This
pump union is indicated by an arrow in the picture above. Water should leak out of the union
once the air has been removed. Tighten the union and test the pump for proper operation.
Repeat this process if needed.
NOTE:
Upon power up, the propulsion system may mix water with air for up to several min-
utes until all of the air is pulled from the propulsion chamber. The propulsion system may be
noisy during this time. This is normal.
6.
Be sure the jets in your swim spa are open.
7.
Adjust water chemistry according to the instructions provided in the “Water Maintenance”
section.
8.
Your swim spa water will heat approximately 1°F (0.5°C) per hour, on average, with the cover
closed on the swim spa. Times may vary.
