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.
READ AND FOLLOW ALL INSTRUCTIONS.
• All permanent electrical connections should be made by a qualified
electrician.
• Follow all applicable electrical codes.
• Be sure all the electrical power is shut off at the main circuit breaker
before installing the MCD.
• 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.
• Do not bury cord.
• Warning – To reduce the risk of electric shock, replace a damaged
cord immediately.
• The MCD must be mounted indoors or, under a cover, sheltered
from natural elements (rain, sun, sprinklers).
• Mount the MCD so that it is inaccessible to anyone in the spa.
• Mount the MCD using the mounting tabs such that the MCD is vertical
with the vents facing downward.
• Install a check valve in the tubing between the MCD and the vacuum
source.**
• Plastic ozone supply tubing is supplied with the MCD. Never replace
this tubing with metal tubing.
• Do not operate the MCD unless sufficient air flow is being drawn
through the unit.
• 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.
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.
