INSTALLATION and STARTUP
WARNING:
Risk of personal injury
Installation procedures must be
performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure could
result in personal injury and property damage.
IMPORTANT:
Power cord is 10' long
If necessary, contact a licensed
electrician to install an appropriate
20 amp electrical circuit with correct
NEMA receptacle.
DO NOT use an extension cord.
CAUTION:
Electrical Shock Hazard
T
he ground prong of the power
cord is part of a system designed to
protect you from electric shock in
the event of internal damage.
DO NOT cut off the large round
ground prong or twist a blade to fit
an existing receptacle.
IMPORTANT:
Not under warranty
Damage to unit due to being
connected to the wrong voltage or
phase is NOT covered by warranty.
WARNING:
Risk of personal injury
Unit is not waterproof, to avoid
electrical shock, keep unit and
counter from being submerged in
water. Do not operate if unit has
been in contact with water.
LOCATION
For proper operation and maximum performance, locate the
unit in an ambient air temperature of 70ºF (21ºC).
Avoid placement in areas near exhaust fans or where there
are active air movements.
For safe operation and maximum performance, locate the
unit at least 2” from any wall or combustible material.
Unit must be on a solid level surface.
GROUNDING INSTRUCTIONS
This appliance is equipped with a cord having a grounding
wire with a grounding plug which must be plugged into an
outlet that is properly installed and grounded. In the event of
an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.
WARNING—Improper use of the grounding can result in
a risk of electric shock. Consult a qualified electrician or
service agent if the grounding instructions are not completely
understood, or if doubt exists as to whether the appliance is
properly grounded.
STARTUP
1. Prior to use, thoroughly clean
the interior of the unit and the
water reservoir, per the instructions in this manual.
2. Install water trough at base of
door. Keyhole cutouts will fit
over bolts at base of door. Slide
trough until the ends are flush
with the edges of the door.
3. Plug the power cord of the cabinet into a grounded outlet
with a minimum 20 Amp 120VAC, 60HZ, single phase
electrical service.
4. Set POWER switch to the “ON” position.
5. Set temperature dial to 190°F. Do not fill humidity pan.
Set humidity dial to off (line up white dot on dial with
white hash mark, located at top of dial on control panel)
6. Do not load product into the cabinet. Allow the heat to
remove any residual oils which may adhere to inside
metal surfaces. A slight emission of smoke is common
during the first few hours of operation.

NORMAL OPERATION
CAUTION:
HOT SURFACE
Inner surfaces of the unit
will be very hot during and
after operation.
Avoid touching the cabinet
when loading or removing
product.
Operating ranges:
- air temp: 85ºF-200ºF
- humidity: OFF-90%
CAUTION:
STEAM HAZARD
This unit produces steam,
use caution when cleaning
or opening the doors.
CAUTION:
WATER HAZARD
A water trough is located at
the base of the door to collect condensation. Make
sure to periodically check
and empty it regularly to
avoid overflow. The trough
can be removed and emptied by simply sliding it off
the bolts at the base of the
door.
The Logix9 Series Humidified Holding Cabinet is equipped with two
dials to control the temperature and humidity settings. Before using,
familiarize yourself with the cabinet controls. See detail on page six
of this manual.
This holding cabinet is equipped with an active air flow and humidity
system. Warm air flows over the water that is heated by an element
in the reservoir and is distributed via ducts on the sides of the cabinet. As the cabinet maintains the desired humidity level, water will
be used from the reservoir. When the water level drops below the
low level probe, the low water light will illuminate. To maintain desired humidity, replenish water supply in reservoir at this time.
HOLDING
1. Fill water reservoir with WARM WATER if humidity is desired
(cabinet may also be operated without humidity). Watch water
level in amber water pan. Do not overfill. Approximate capacity:
HWU5, HWU8, HWC10 & HWC16: one gallon
HWU14, HWU18, HWC28 & HWC36: two gallons
2. Turn cabinet on and set temperature and humidity dials to
desired settings (see chart on page 8). Allow cabinet to preheat
for 45 minutes.
3. Load cabinet with pans or trays. Load from top to bottom for
best results.
4. When removing items, start at the bottom and work to the top.
This keeps food hotter and eliminates spillage onto lower items.
Due to food safety concerns, we recommend that the holding
temperature should not be set below 140°F.
PROOFING
1. Fill water reservoir with WARM WATER. Watch water level in
amber water pan. Do not overfill. Approximate capacity:
HWU5, HWU8, HWC10 & HWC16: one gallon
HWU14, HWU18, HWC28 & HWC36: two gallons
2. Turn cabinet on. Set temperature dial to lowest setting and
humidity to 90% (H, Yellow Zone). Allow cabinet to preheat for
45 minutes.
3. Load cabinet with pans or trays. Load from top to bottom for
best results.
4. Proof according to your recipe instructions.
5. When removing items, start at the bottom and work to the top.
This keeps food hotter and eliminates spillage onto lower items.
Water reservoir located at top left of cabinet interior.
To fill, pull out metal frame with pan. IF CABINET IS HOT, USE OVEN MITTS AND
PROCEED WITH CAUTION—FRAME AND WATER WILL BE HOT.
To remove, pull out metal frame. DO NOT REMOVE IF CABINET OR WATER IS
HOT. ALLOW CABINET TO COOL COMPLETELY. While holding metal frame, slide
pan to rear and then lower to clear the frame. To install, reverse procedure.

edges with sheet
metal during cleaning process.
:
:
1. After all food products have been removed from the cabinet,
turn the power switch to “OFF” and allow the cabinet to cool.
2. Unplug the unit prior to any cleaning.
3. Remove and clean the water pan from the inside top of the
cabinet. Caution, water may still be hot from prior use. A vinegar & water solution may be used to remove stubborn mineral
deposits. Remove and clean the water drip pan mounted to
the bottom of the door.
4. Remove the side heat duct and rack assemblies. Clean the
inside of the unit as well as the removed parts. Reinstall when
all parts are dry and clean.
5. Inspect and clean the areas where there are vents or filters,
making sure no water gets into the internal controls or
electrical areas of the cabinet.
6. Plastic control panel should be washed with a clean damp
cloth and chlorine-free detergent. Rinse thoroughly with clean
damp cloth and allow to dry. Do not use abrasive cleaners,
waxes, car polish, or substances containing strong aromatic
solvents or alcohol.
CAUTION:
sanitizers, or bleaching agents that contain chlorides or
phosphates will cause permanent damage to stainless
steel products. The damage appears as pits, eruptions, voids,
small holes, severe discoloration or dulling of the metal finish.
Water with high chloride content can also damage stainless
steel. If unsure of your water quality, we recommend you have it
tested. THIS DAMAGE IS PERMANENT, COSTLY TO REPAIR,
AND IS NOT COVERED BY THE WARRANTY.

CABINET MAINTENANCE
WARNING:
DO NOT perform
these procedures
while the cabinet is turned on
or heated. Turn off the power
and wait for the cabinet to cool
to room temperature.
CAUTION:
Do not move cabinet
unless door is securely closed. Serious damage to hinges and door may
result if bumped into tables,
walls, or other equipment when
the doors are open.
CASTERS
Caster bearings are equipped with Zerk grease fittings so that they
may be easily lubricated with a grease gun. Lubricate bearings at
least once every six months.
REPLACING THE DOOR GASKET
1. Remove the screws located under the gasket on the cabinet.
2. Remove the gasket and discard.
3. Install the new gasket and replace the screws.

aside. Removing the covers will allow access to the inside
hinge screws. Remove the three screws that hold each hinge
to the cabinet. DO NOT REMOVE THE SCREWS THAT
HOLD THE HINGES TO THE DOOR. Remove the door, taking care not to let it fall.
2. Remove the door strike plate and screws adjacent to the door
opening on the cabinet. Reinstall door strike plate and screws
on opposite side of the cabinet.
3. Screw hinges onto opposite side of the door.
4. With the help of another person, hold door up to the cabinet
and attach with the screws removed in step one. Before tightening the screws, be sure the door is flush, level and square.
Replace the hinge covers.
