IMPORTANT SAFETY INSTRUCTIONS
Proper installation and safe use of your DEL spa ozone generator is your re-
sponsibility. Read and follow this Owner’s Manual carefully for important instal-
lations, operation and safety information. Basic safety precautions should al-
ways be followed, including 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 all the electrical power is shut off at the main circuit breaker
before installing the ozone generator.
5. Connect to a grounded grounding-type receptacle only.
6. If the ozone generator 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 DEL spa ozone generator is
connected to an independent electrical supply, then a G.F.C.I. must be
installed between he ozone generator and the electrical supply.
7. A pressure wire connector (ground lug) is provided on the outside of all
ZO-300/301/302 ozone generator units to allow the connection of a
minimum No. 8 AWG (8.4 mm
2
) solid bonding conductor (wire) between
this point and any metal equipment, metal enclosure of electrical equip-
ment, metal water pipe, or conduit within five (5) feet (1.5m) of the unit,
as needed, to comply with local requirements.
8. Do not bury the cord.
9. WARNING: To reduce the risk of electric shock, replace a damaged cord
immediately.
10. Per U.L. requirements, the ozone generator must be mounted indoors, or
under a cover, sheltered from the natural elements (e.g.: rain, sun,
sprinkler).
11. The ozone generator must be mounted above the water line, at least five
(5) feet away from the spa and at least one (1) foot above the water level.
12. Mount the ozone generator so that it is inaccessible to anyone in the spa.
Never attempt any servicing while wet.
13. To reduce the risk of injury, this unit should be mounted where it is
inaccessible to children.
14. Plastic ozone supply tubing is supplied with the ozone generator. Never
replace this tubing with metal tubing, as ozone will damage it.
15. Do not operate the ozone generator unless sufficient air flow (~2 scfh) is
being drawn through the unit.
16. WARNING: Short term inhalation of high concentrations of ozone and
long term inhalations of low concentrations of ozone can cause serious
harmful physiological effects. Do not directly inhale ozone gas produced
by this device (i.e. do not inhale directly from tubing or ozone generator).
