Hydropool SS14ES - Pump Priming and Air Lock Release

FILLING, CHECKING AND STARTING YOUR SWIM SPA—ALL OTHER SWIMSPAS
CHECKING
Although your swim spa was thoroughly water-tested in the
factory, some loosening of fings can occur during shipping.
Before any decking, ling or carpeng is completed around
the installaon, fill and operate your hot tub to test for leaks
(this ensures easy access and inexpensive correcon). Check
all union connecons and plumbing for minor leaks. In the
event of a leak, ensure all union connecons and pump plugs
are ght and all o-rings/gaskets are in place.
STARTING
Before applying voltage to power-up your swim spa, it is very
important that you understand the sequence of events that
occur when the system is acvated in order that the pump
can be primed efficiently and damage to the system can be
avoided.
· Turn the main power “on” at your electrical panel.
· Follow the control instrucons for your parcular model
swim spa to put the pump into low speed.

PUMP PRIMING/RELEASING AN AIR LOCK
• On some systems a message will appear on the display
indicang that the system is in PUMP PRIMING MODE.
This mode will last for 4 to 5 minutes before automacally
entering the normal operaon mode. See complete details
for your spa in secon HYDROPOOL CONTROL SYSTEMS
When the pump is located below water level, the water
should start circulang immediately. If the motor works but if
you do not noce water circulaon within the first 15
seconds, the pump may require priming due to trapped air
(referred to as an ‘air lock’). To prime (inset 2), open the hose
-bib to allow trapped air to escape. Close as soon as the water
flow from the jets becomes regular. If the pumps have not
primed aer 2 minutes, and water is not flowing from the
jets, DO NOT allow the pumps to connue to run. Turn power
off at the main house panel (or GFCI) and try releasing the air
again by loosening the union on the discharge side of the
pump(s) while the motor is not running. Turn the power back
on. If the pump(s) does not prime aer 15 seconds,
somemes momentarily turning the pump(s) off and on will
help the system to prime (note: do not do this more than 5
mes). Repeat if necessary.
• Important: Under NO circumstances should the pump(s) be
allowed to operate without priming beyond 5 minutes, as this
may not only cause unwarrantable damage to the pump, it
may also cause the control system to go into an overheat
condion.
Definion: ‘Priming’ a pump is a term used to describe the
process in which air trapped in the plumbing and pump
wetend (referred to as an ‘air lock’) is released, allowing the
pump to move water efficiently through the plumbing system
and to the jets.
FILLING
• When adding water for the first me, the swim spa should
be filled through the skimmer opening (helps to prevent air
locks) using a standard garden hose, turning the tap on
slowly to prevent damage to the surface by a jerking hose
connecon.
• Pull up the handles on the intake and return gate valves
and clip on the stem locks. (handles are pulled up when
valves are open and pushed down when valves are closed).
· Ensure the drain valve is closed.
· Ensure that all jets are open.
· Fill the swim spa to the recommended level as indicated
by the “MIN” and “MAX” marks on the weir door of the
skimmer opening.
