Removing An Airlock - Strong Monaco 20 Owner's Manual

REMOVING AN AIR LOCK
NOTE: See Union Adjustment Information before operating spa.
Before starting up your spa, make sure you have read and under-
stand 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 with clip installed. See page 6.
• The circuit breaker on the control panel has automatic func-
tions that operate upon start up and normal operation to protect
the system. Upon power up, "PR" will appear for 2 minutes while
system is in purge mode and then normal operation will resume.
Approximately six 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 may sound sluggish and the flow from
the jets will be minimal, this indicates you have an air lock in the
pump. To release the air from the pump, simply 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 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 overtighten 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.
