Part 9
PORTABLE CONTROL UNIT MESSAGES
CHECK 1 - Water Level
Ensure water level meets fill lines on both interior
sides of the spa. Check if this resolves the PCU’s
malfunctioning.
CHECK 2 - Inside Connection Caps
Make sure the plastic Inlet/Outlet caps have been
removed before turning on the PCU.
CHECK 3 - Bleed Air out of Portable
Control Unit
If PCU makes a grinding noise, no water is going to the
pump. Turn the PCU off. Bleed the air out of the pump by
unscrewing the Air Valve until a small amount of water is
released then re-tighten it. Check if this resolves the noise.
CHECK 4 - Check Spa for Obstructions
Check that inlet/outlet ports inside the tub are clean
and remove any obstructions detected. Check if this
resolves the PCU’s malfunctioning.
CHECK 5 - Ensure Filter is Clean
Check the filter. If the filter is dirty or scaled, wash and/or
replace it. Check if this resolves the PCU’s
malfunctioning.
CHECK 6 - Ensure Connectors are Not
Kinked
Check the connection hoses. Make sure that they are not
kinked or bent and that both the spa and the PCU are
set on the same level surface. If you still cannot solve this
problem, please contact us for service.

SPA OPERATION CHECK LIST
CHECK 7 - Back Flush PCU
Back flushing the PCU is a good practice to carry out every few
months to aid in PCU performance and longevity. Simply remove
the PCU from the tub connections (cap ports inside tub first if
you do not want to drain spa) remove the filter and run water
from a garden hose into the ‘Heater Port’. Flush for 30 seconds
and hold PCU upside down to drain remaining water.
