SECTION 2 Maintenance
For optimum performance, we recommend the MCD be replaced
every five years. Ozone tubing and check valve should be replaced
annually. Follow the steps below to replace the MCD and tubing. Refer
to Figure 2.
Condensate may collect in dips or loops in the tubing. If
NOTICE
condensation appears in the tubing, DO NOT DRAIN IT as the moisture may be
moderately corrosive. Disconnect the power to the MCD and allow the liquid to be
drawn out or dried up before removing the tubing.
Wear proper safety equipment (gloves and eye protection).
CAUTION
1. Remove the MCD From Your Spa
a. Shut off power to the spa.
b. Disconnect the ozone tubing from the MCD outlet hose barb.
c. Open the spa controller panel and disconnect the MCD power
cord.
d. Remove the mounting screws and remove the MCD from the spa.
e. Disconnect the ozone tubing from the injector port (or MDV port if
spa is equipped with a mixing vessel).
2. Install the New MCD
a. Reverse the steps above to install the new MCD.
b. Connect one end of the new tubing to the injector or MDV port,
connect the other end to the MCD.
c. If the check valve is pre-installed in the tubing, secure the check
valve as high as possible in the equipment area. Otherwise, run
the tubing to the highest point possible, cut the tubing and install
the check valve. In either case, ensure the check valve flow arrow is
pointing towards the injector.
