IMPORTANT SAFETY INSTRUCTIONS
When installing and using DEL Models MCD, basic safety precautions should always
be followed:
Be sure all the electrical power is shut OFF at the main circuit breaker before installing
the MCD.
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. All permanent electrical connections should be made by a qualif ed electrician.
3. Follow all applicable electrical codes.
4. Be sure all the electrical power is shut off at the main circuit breaker
before installing the MCD.
5. If the MCD electrical connections will be attached directly to the spa controls, be
sure the spa controls are protected by a Ground Fault Circuit Interrupter (G.F.C.I.).
If the MCD is connected to an independent electrical supply, then a G.F.C.I. must
be installed between the MCD and the electrical supply.
6. Do not bury cord.
7. WARNING: To reduce the risk of electric shock, replace a damaged cord immedi-
ately.
8. The MCD must be mounted indoors or, under a cover, sheltered from natural ele-
ments (rain, sun, sprinklers).
9. The MCD must be mounted above the water line.
10. Mount the MCD so that it is inaccessible to anyone in the spa.
11. Mount the MCD using the mounting tabs such that the MCD is vertical with the
vents facing downward.
12. Install a check valve in the tubing between the MCD and the vacuum source.**
13. Plastic ozone supply tubing is supplied with the MCD. Never replace this tubing
with metal tubing.
14. Do not operate the MCD unless suf f cient air f ow is being drawn through the
unit.
15. WARNING: Short term inhalation of high concentrations of ozone and a long term
inhalations of low concentrations of ozone can cause harmful physiological effects.
Do not inhale ozone gas produced by this device.
16. SAVE THESE INSTRUCTIONS.
** A condensate may collect in dips or loops in the tubing. For best results install the
MCD just above the vacuum source and use a short, straight piece of tubing to
make the connection. If condensation appears in the tubing, DO NOT DRAIN IT,
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.
