Operating instructions

Prior to spa operation, plumbing fittings on pump & control pack must be tight-
ened. Spa is shipped with loose unions to avoid damage during transportation.
There are FOUR unions that require hand tightening prior to operation of your
spa. When filling the spa with water, keep observing these fittings for any slight
water drips. If a drip is observed, just hand tighten until dripping ceases.
REMOVING AN AIR LOCK
NOTE: See Union Adjustment Information before operating spa. Before starting up your spa,
make sure you have read and understand all of the previous instructions. Make sure the spa has
been installed correctly, including the electrical wiring connections as specified,
• Spa’s water is at the correct level
• Ensure all gate valves are opened
• The circuit breaker on the control panel has automatic functions that operate upon start up and
normal operation to protect the system. Upon power up, “PR” will appear for 30 seconds while
system is in purge mode and then normal operation will assume. Approximately two minutes
after the system has been powered up the first filtration cycle will begin to operate. Any time after
the start up, you will be able to change the filter cycle and reset your temperature set point.
Upon startup, the pump(s) may sound sluggish and the flow
from the jets will be minimal, this indicates you have an air
lock in the pump(s). To release the air from the pump(s), sim-
ply open the highest union (or upper union) to release the air
trapped in the water lines, or gently, using a 17mm or 18mm
wrench (varies on pump size) slowly loosen the black plastic
hex head bolt in front of pump. You will hear air being pushed
out the union or bolt, once the air stops and water starts to
come out, the pump(s) will pick up speed and the jets flow
will increase. Carefully tighten the union or bolt until the water
does not leak from the union or bolt. Be careful not to over-
tighten the black hex head bolt this may cause the bolt to strip
or you may pinch the gasket. Strong recommends that you
loosen the upper union to relieve the air from the lines since
this method lessens the chance of stripping the hex bolts.
