Original instructions
Connecting the Electrical Supply Source
to the Protector Echo Hood
Prior to connecting any electrical wiring to the fume hood structure, refer to the
hood identification plate for the proper electrical requirements of your specific
model.
WARNING: The building electrical supply system for
Protector Hoods should include overload protection. A switch
or circuit breaker should be in close proximity to the
equipment and within easy reach of the operator. The switch
or circuit breaker is to be marked as the disconnecting device
for the equipment. Consult the current version of NFPA 70
® ,
NEC ® for proper installation.
AVERTISSEMENT : Le système d’alimentation électrique de la
Hotte Protecteur doit inclure la protection contre la surcharge. Un
commutateur ou disjoncteur doit être tout près de l'équipement et
à portée facile de l'opérateur. Le commutateur ou le disjoncteur
doit être marqué comme l'appareil débranchant pour
l'équipement. Consultez la version actuelle de la norme NFPA 70
® ,
NEC ® pour une installation correcte.
The identification plate, model number, serial number, and electrical connection
boxes are accessible from the front of the fume hood by removing the front panel.
The Protector Echo Hood is normally wired for 115 Volt, 50/60 Hz, 20 Amp or
230Volt, 50/60 Hz, 10 Amp electrical service. Check the I.D. plate behind the
front panel for voltage verification. The number of circuits varies depending on
the model. All of the electrical connections for the individual duplexes are
terminated at the single point internal junction box for hook-up by a qualified
electrician. If needed, the individual duplexes can be converted for instant
attachment to a wall outlet by a qualified electrician by ordering 115V harness
9582700 or 230V harness 9582701. The main power to the control panel, fans,
and lights uses less than 3 amps and a main power cord is included for instant
attachment to a wall outlet. However, these power connections can be
disconnected at the field wiring terminal box for hook-up by a qualified electrician.
We recommend each circuit be a dedicated branch circuit. However, if wired
together the maximum load allowed is the sum of individual outlets plus the rating
of the unit (i.e. less than 3 Amps). The single point internal junction box is used for
the connection of the lights, blower, and duplex outlets. Refer to the wiring
diagram for your Protector Echo in Appendix C: Protector Echo Specifications.
The fume hood is required to be grounded to the MAINS protective earthing ground
for safe operation. Using a ring terminal sized for a 10-24 machine screw, connect
the MAINS ground conductor to the grounding lug marked with the protective
earthing symbol, . Only MAINS ground conductors should be connected to the
