UNPACKING AND INSTALLATION
WARNING:
Risk of personal injury
Installation procedures must
be performed by a qualified technician
with full knowledge of all applicable
electrical codes. Failure can result in
personal injury and property damage.
CAUTION:
Electrical Shock Hazard
The 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:
Power cord is 10' long.
If necessary, contact a li-
censed electrician to install
an appropriate 15 amp electrical cir-
cuit with NEMA 5-15R receptacle. DO
NOT use an extension cord.
IMPORTANT:
Damage to unit due to being
connected to the wrong volt-
age or phase is NOT covered
by warranty. 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 electrical 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.
CAUTION: Electric Shock Hazard
All servicing requiring access to non-insulated components must be performed by qualified service personnel. Do
not open any access panels which require the use of tools. Failure to heed this warning can result in electrical
shock. Disconnect this appliance from electrical power before performing any maintenance or servicing.
WARNING: Injury Hazard
All installation procedures must be performed by qualified personnel with full knowledge of all applicable electrical
codes. Failure could result in property damage and personal injury.
WARNING Electric Shock Hazard
Appliance must be plugged into a properly grounded receptacle to prevent possible shock hazard. Electrical shock
will cause death or serious Injury.

CLEANING
Turn the main power switch OFF and unplug the cabinet to before cleaning. DO
NOT spray or splash water on the electrical components, control panel, timer or
wiring.
1. Racks or shelves are easily removed without tools for cleaning, Simply lift up
and pull out. The tray racks may be hand washed or run through an automatic
washer.
2. To clean stainless steel surfaces use only cleansers, detergents, degreasers,
or sanitizers that are certified to be "chloride-free" and "phosphate-free," and
cleansers, degreasers, or sanitizers only in the recommended concentrations.
DO NOT exceed recommended concentrations or mixing ratios. After clean-
ing and sanitizing, rinse all exposed surfaces thoroughly with large amounts
of clean, clear water. Wipe off any standing liquid or residue from all surfaces,
corners and rear edges.
3. Vinyl trim should be washed with a chlorine-free detergent and water. Rinse
thoroughly with clear water and allow to dry. Never use abrasive cleaners,
waxes, car polish, or substances containing strong aromatic solvents or alco-
hol. Use of direct steam / hot water cleaning at temperatures above 190°F
may result in “bubbling” or loosening of vinyl adhesive.
4. After all parts are dry, reinstall them and then plug the cabinet back into elec-
trical source.
IMPORTANT: Cleansers, detergents, degreasers, sanitizers or bleaching agents that contain chlorides or
phosphates will cause permanent damage to stainless steel products. This damage appears as pits,
eruptions, voids, small holes, cracks, severe discolorations or dulling of the metal finish. Water with a high
chlorine 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 WARRANTY.

TO CHANGE THE SET-POINT
1. Access the “Machine Status” menu by pressing the SET key

PHB refrigerators are capable of cooling to a temperature of 32°F (O°C). Pre-
cooling time to 40°F (4°C) is approximately 40 minutes. Only product that has
been pre-chilled should be placed into the cabinet. Placing warm product will
elevate the cabinet air temperature above 40°F (4°C) . This will have a direct
effect on optimum serving temperatures.
Due to various conditions such as extremely high kitchen temperatures and/
or humidity, high frequency of tray activity and excessively long operations,
the door may need to be closed so the unit can recover to proper operating
temperature.
1. Pre-chill empty cabinet with the door closed for approximately 40
minutes. Always keep the door closed, except when actually loading or
unloading the cabinet. Do not load the cabinet until the proper operating
temperature has been reached (34°-40°F for refrigerators. Power switch
will illuminate when cabinet is “ON”.
2. Load the cabinet from the bottom to the top. After loading, close the
door and allow the inside air temperature to recover.
3. If necessary, unplug and move cabinet to serving area. Plug cabinet
back in immediately upon arrival.
4. Unload the cabinet from the top down.
5. Close the door during slow periods to extend the effective temperature
maintenance time.
Remember: the refrigerator must be at proper
temperature before the door is opened.
The cabinet will not lower food temperatures with the door open.
The cabinet is equipped with an automatic condensate evaporator. To pre-
vent water spills, leave the unit plugged in, with the door closed for at least 90
minutes after use.

GENERAL MAINTENANCE INSTRUCTIONS
DOORS
Never tip cart forward or open doors to drain water during or after washing. This can
cause serious damage to the hinges, doors and latches.
CASTERS
Some casters are equipped with Zerk grease fittings so that they may be easily lubri-
cated with a grease gun. Recommended lubrication is at least once every six months.
Lubrication will be required more frequently if carts are cleaned with a hot water or
steam cleaning system. Casters with special bearings are recommended for frequent
cart wash or steam cleaning situations.
HINGES
Your cart doors and hinges have been factory aligned with nylon spacers to assure
positive latching and smooth action. Be sure to replace these washers if the are re-
moved when cleaning doors and hinges. If doors are removed for cleaning, we recom-
mend that they be put back on the same cart to assure the best possible alignment and
operation.
LATCHES
Check frequently to insure that all door latches are secure. Latches may become
“sticky” due to residue build-up from daily use and cleaning. Lubricate latches regularly
with WD-40, silicone spray, graphite or other commercial lubricants for stainless steel
products. Do not use oil.
PERIMETER BUMPERS
Vinyl which has been dislodged from the channel due to severe bumping or scraping
can be pried back into place with a common screwdriver.
WARNING
Never move cart unless
all doors are securely
closed. Serious damage
to hinges and doors may result if
bumped into walls, tables, or other
equipment when the doors are open.
REPLACEMENT PARTS
WARNING
Use only (OEM) original
equipment manufacturer
replacement parts. Using
unauthorized parts may cause serious
injury. Replacement parts should be
installed by a qualified technician.
Contact factory with your model and serial number for replacement
components.
