JABSCO 34739 series User manual
Model 34739-Series
(NOTICE: Tighten screws evenly to avoid flange
damage). Use outlet collar No.34856-0000 to connect
ducting to discharge vent. Use a suitable discharge fitting
so that static pressure of blower will not be affected by
change in wind direction. Route inlet ducting with as few
bends as possible to lower 1/3 of bilge compartment
where vapors are likely to accumulate.Be sure ducting is
positioned below top of engine stringers but not so low
as to become submerged in bilge water.Locate pickup to
take advantage of natural air flow direction.Flexible duct-
ing No.34959-0100 is easy to cut and install.
NOTICE: Blower should be mounted away from
extreme heat (more than 130°F) to prevent distortion of
blower wheel or housing.
For an exposed inlet, ventilator intake screen No.34764-0000
provides a safe and attractive protected inlet. NOTE:
This blower may also be mounted with inlet through bulk-
head, using intake collar No. 34943-0000.
Jabsco blowers are primarily intended for intermittent
duty cycles such as evacuating fuel vapors from bilge
areas. If desired, they also may be used for other general
air circulation applications with longer duty cycles.
However, when doing so, it should be noted that the
maximum motor life is approximately 1000 hours.
Therefore, the blower should only be used for
applications if this length of service is acceptable.
OPERATION: See following warning placard statement:
The “WARNING” placard supplied with blower must
be mounted adjacent to engine ignition switches (all
Locations) to comply with Title 33, Part 1834;
Subpart K, USCG Ventilation Regulations.*
*Additional warning placards are available from factory by requesting
form 43003-0418.

WIRING FOR DC MODELS: Use stranded copper wire.
For lengths up to 25 feet (7.6m) from power source: Use
12 gauge wire for 12 Volt and 14 gauge wire for 24 Volt.
Use larger wire for longer lengths. Use a 10 amp rated
on-off switch in positive side of circuit (Model 44960-
0003). Circuit must be protected with a fuse.Suggested
fuse sizes are listed in the specifications table.
WIRING FOR AC MODEL: Use 16 gauge stranded
copper wire for lengths up to 100 feet from power
source. Connect the grounded, unswitched conductor
(white) to the white motor lead.Connect the undergrounded,
switched conductor (black) to the black motor lead. This
conductor should include, at the power source, a 1.25
amp 125 Volt fuse. The green motor lead must be
connected to the AC circuit ground.
