Installation Instructions - Master Spas Trainer 12 Owner's Manual

INSTALLATION INSTRUCTIONS

1.
Put swim spa in final position that allows for access to equipment and swim spa components.
2.
Remove front skirt panel "A" to access the electrical connections.
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.
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 purpose 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, Inc. 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 warranty 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 below. 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.
6.
Be sure the jets in your swim spa are open. See 55 page for removal instructions.
7.
Adjust water chemistry according to the instructions provided in the Swim Spa "Water Quality
Maintenance" Section. (page 23).
8.
Your swim spa water will heat approximately 1° - 2° per hour, on average. Times may vary.
DO NOT DIVE.
