IMPORTANT SAFETY INSTRUCTIONS
Proper installation and usage of your DEL Spa Ozone Generator is your responsibility. Read
and follow this Owner’s Manual carefully for important installation, operation and safety
information. Basic safety precautions should always be followed, including but not limited to
the following:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. All electrical connections should be made by a qualified electrician.
3. Follow all applicable electrical codes.
4. Be sure the electrical power is shut OFF at the main circuit breaker before installing the
Ozone Generator.
5. If the Ozone Generator electrical connection is to be attached to the spa controls, be sure
the spa controls are protected by a Ground Fault Circuit Interrupter (G.F.C.I.). If the DEL Spa
Ozone Generator is connected to an independent electrical supply, then a G.F.C.I. must be
installed between the Ozone Generator and the electrical supply.
6. A pressure wire connector (ground lug) is provided on the outside of all ZO-300/301/302
and Platinum ozone generator units to allow the connection of a minimum No. 8 AWG (8.4
mm2) solid bonding conductor (wire) between this point and any metal equipment, metal
enclosure of electrical equipment, metal water pipe or conduit within five (5) feet (1.5m) of the
unit, as needed, to comply with local requirements.
7. Do not bury cord.
8. WARNING - To reduce the risk of electrical shock, replace damaged cord immediately.
9. Per UL requirements, the Ozone Generator must be mounted indoors or under a cover,
sheltered from natural elements (rain, sun, sprinklers).
10. Mount the Ozone Generator so that it is inaccessible to anyone in the spa. Never attempt
servicing when wet.
11. To reduce the risk of injury, the unit should be mounted where it is inaccessible to children.
12. Plastic ozone supply tubing is available with the Ozone Generator. Never replace this tubing
with metal tubing.
13. Do not operate the Ozone Generator unless sufficient air flow is being drawn through the
unit (see Section 9c).
14. WARNING: Short term inhalation of high concentrations of ozone and long-term
inhalations of low concentrations of ozone can cause harmful physiological effects. Do not
inhale ozone gas produced by the device.
