INSTALLATION FOR LOCATION “C”:
Turn off the electrical power and drain the spa at least 12 inches below the air
venturi line which provides the best suction and is connected to the lowest
jet. Cut the PVC flex tube approximately 3” to 4” from the air control valve.
Install an appropriately sized PVC reducer fitting (not included), with 1/2”
female threads on one end. Be sure to use FLEX-TO-RIGID- PVC Cement
whenever working with PVC flex tubing. Wrap Teflon tape on the plastic hose
connector threads and install into the reducer fitting, securing ozone supply
tubing. This entire assembly should be secured as close to the top of the spa
waterline as possible. NOTE: This installation will cause ozone to be drawn
only through the jet(s) dedicated to this venturi air line no matter what position
the air control valve is in.
Attach the 5’ of tubing with check valve installed to the ozone generator
cartridge. Be sure the check valve bevel is pointed towards the spa and away
from the ozone generator. See ELECTRICAL CONNECTION to complete
installation. When final electrical connections have been made, fill the spa to
its normal operating level and turn the power back on. Proceed to the DEL
SUCTION TEST section before final connection of ozone supply tubing is
made.
INSTALLATION FOR LOCATION “D” (TWO-SPEED PUMPS):
For the location “D” connection, a DEL RIGID INJECTOR MANIFOLD (DEL
Part Number IU-201) is required - contact your local dealer (See Figure 5).
