INitial Spa Setup
7.
It may be necessary to bleed air from the pump(s) in your spa if, after start up, your spa
pumps are turning on and off but you do not have water flow from the jets in your spa.
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 refilling a spa. This is not a service covered under 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 opera-
tion. Repeat this process if needed.
8.
Adjust water chemistry according to the instructions provided in the "Water Maintenance"
section.
9.
Your spa water will heat approximately 3 to 4 degrees Fahrenheit per hour (1 to 2 degrees
Celsius) with the cover placed on the spa. This varies depending on the size of the spa and
ambient temperatures.
