AVERTISSEMENT:

ELECTRICAL:
In the USA this machine operates on a standard 15

amp 115V, 60 hz, A.C. power circuit. The amp, hertz,
and voltage are listed on the data label found on each
machine. Using voltages above or below those
indicated on the data label will cause serious damage
to the machine.

EXTENSION CORDS:
If an extension cord is used, the wire size must be at

least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.

GROUNDING INSTRUCTIONS:
This appliance must be grounded. If it should malfunc-

tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi­nances.

This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in "Fig.
A". A temporary adaptor that looks like the adaptor in
"Fig. C" may be used to connect this plug to a 2-pole
receptacle as shown in "Fig. B", if a properly grounded
outlet is not available. The temporary adaptor should
be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green
colored rigid ear, lug, or the like extending from the
adaptor must be connected to a permanent ground
such as a properly grounded outlet box cover.
Whenever the adaptor is used, it must be held in place
by a metal screw.

Safety

Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
Check with a qualified electrician or service person
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the appliance - if it will not fit the
outlet, have a proper outlet installed by a qualified
electrician. Use only GFCI protected receptacles.

Le raccordement incorrect du conducteur de terre
d'équipement peut entraîner des risques d'électro­cution. Vérifiez auprès d'un électricien qualifié ou
d'un responsable de l'entretien si vous avez
quelque doute que ce soit quant au ra ccordement à
la terre de votre prise murale. Ne modifiez pas la
fiche fournie avec l'appareil : si elle ne correspond
pas à la prise murale, faites installer une prise
adéquate par un électricien qualifié. Utilisez-le
uniquement sur des réceptacles protégés GFCI.

How to T ransport Dehumidifier

1. Wrap the power cord around intake nozzle.

2. Tilt on back wheels with exhaust outlet pointing up.

3. Pull by handle.

4. Place the machine back down on its base.

5. Position exhaust as desired.

Cord Storage

Fans power cord is best stored around neck of intake
nozzle.

1. Turn off machine.

2. Working from machine to cord plug end, lay cord
out straight, remove any twists as you go.

3. Make a 2” loop in cord near strain-relief then wrap
cord snugly around neck of intake nozzle coiling
from bottom up.

4. Allow cord to untwist as you coil cord around intake
neck.

Storing in Warehouse and in Delivery
Truck:

Dehumidifiers should always be stored and transported
in an upright position. If the dehumidifier is transported
in a horizontal position, upon being set upright the unit
should not be operated for 30 minutes. Always store
the dehumidifier inside away from weather, in an area
not exposed to excessive heat or cold.

5. Secure cord end by attaching cords plug retaining
clip to cord of the previous loop.

Operations

Operating Dehumidifier

Never allow anything to block intake airflow. Be
careful of objects which could be drawn against
intake. The fan must sit on a level surface. Always
position and orient machine before turning on.

Ne permettez jamais à quoi que ce soit de bloquer
l'entrée d'air. Faites attention aux objets qui pour­raient être attirés contre l'entrée d'air. Le ventilateur
doit reposer sur une surface de niveau. Dirigez et
orientez toujours le ventilateur avant de l'allumer.

For best results, operate dehumidifier in enclosed
space. Close all exterior doors and windows. Keep
traffic through drying area to a minimum

1. Connect drain hose to condensate pump’s quick
connect fitting.

2. Uncoil and straighten entire hose; to prevent water
backing up to pump and leaking.

Ducting

Switch off and unplug machine from its power
source before connecting ducting.

Arrêtez et débranchez le ventilateur de sa source
d'énergie avant de relier la canalisation.

Be aware that ducting will move as it inflates or has
air moving through it.

Prenez conscience que la canalisation se
déplacera alors qu'elle se gonflera ou alors que l'air
passera à travers.

3. Place other end in a sink drain bucket or outside,
no more than 10 ft above pump.

NOTE: If a bucket or other receptacle is used for
water collection, check and empty regularly to
prevent spills.

4. Plug in electrical cord into 115 volt GFCI protected
outlet rated for minimum 15 amps.

5. Turn the machine on.

86352290 Trident LGR Dehumidifier

Operations

Exhaust Ducting

1. Place quick-ducting band over lay-flat duct
approximately 1 foot from end.

2. Slide ducting 3 or 4 inches over front exhaust
nozzle, make sure it is even all around.

3. Secure in place by sliding quick-ducting band
along ducting and over exhaust ducting flange.

4. Verify that ducting is sandwiched b etween machine
exhaust nozzle and quick-ducting band and even
all around making a good seal.

5. Position machine and ducting in desired orientation
and location.

6. Plug machine into power source.

7. Switch machine on.

8. Observe ducting as air starts to flow through it,
ducting may move around.

Intake Ducting

1. Unwrap cord from cord storage area.

2. Place a quick-ducting band over ridged spiral duct
about 1 foot from end.

3. Slide ducting 3 or 4 inches over top intake nozzle,
make sure it is even all around.

4. Secure in place by sliding quick-ducting band
along ducting and over the intake ducting flange.

5. Verify tha t ducting is sandwiched between machine
intake nozzle and quick-ducting band.

6. Position machine and ducting in desired orientation
and location.

7. Plug machine into power source.

8. Switch machine on.

9. Observe ducting as air starts to flow through it,
ducting may move around.

Operations

Back Draft Prevention

Exhausting too much air from a space with Open
Combustion Devices (e.g. furnace, fireplace or
water heater) can cause those devices to back draft.
This can contaminate the space with potentially
fatal gases.

Évacuer trop d'air d'un espace av ec des app areils à
combustion ouverte (p ex., fournaise, foyer ou
chauffe-eau) peut entraîner un refoulement de ces
appareils. Cela peut contaminer l'espace avec des
gaz potentiellement mortels.

Use the machine as a dehumidifying unit only.
Exhausting no air from the space and thus causing no
negative pressure or back drafting.

OR

Exhaust a very limited amount of air , which do es not
cause back drafting.

OR

Direct one or more forced air outlet ducts into the room
with combustion devices. This will positively pressurize
the room, thus preventing back drafting.

Purging Dehumidifier

1. After space reaches desired humidity level, pr ess
switch to Purge. This manually empties water from
the condensate pump reservoir.

2. Hold switch to purge setting until the pump is
empty.

3. Disconnect drain hose.

NOTE: The drain hose will be full of water. Take
precautions to avoid spilling in undesirable areas.

When exhausting air from a space, always check
Combustion Devices with the machine running to
guarantee that back draft prevention measures are
working.

En évacuant l'air d'un espace, toujours vé rifier que
le ventilateur des appareils à combustion ouverte
est en marche pour garantir l'efficacité des
mesures de prévention antirefoulement.
