Power up Spa and Set Water Temperature. The following steps provide guidance to help establish correct chem-
ically balanced water. To help ensure chemicals dissolve appropriately it is good practice to rst mix/dissolve the
chemical in an uncontaminated container of hot water before carefully adding to the spa water.
Steps to Fill Spa With Water Power Up Spa and Set Water Temperature
Step 1. Fill Spa Fill your spa through the lter intake as
shown
to the appropriate level (just under the head rests). If
you have sediment or high mineral content a “carbon
lled pre-lter”, as pictured, can help. (This is optional
and will prolong the ll time).
Step 2. Connect/Turn on Electrical Power to the spa
once the spa is lled to the proper level, and turn the
power on to the spa on.
Step 3. Set Water Temperature Set the water tempera-
ture control on the Topside Controller to the desired
temperature (between 100ºF and 104ºF or 38°C and
40°C).
