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 cov-
ered 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 warn-
ing 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 applica-
ble 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.
Unpack the cart and any accessories included. Ensure that all pack-
ing materials and protective plastic has been removed from the unit.

CLEANING
Turn the main power switch OFF and unplug the cabinet to before clean-
ing. DO NOT spray or splash water on the electrical components, con-
trol 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, de-
greasers, 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 con-
centrations or mixing ratios. After cleaning 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 abra-
sive cleaners, waxes, car polish, or substances containing strong aro-
matic solvents or alcohol. 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 electrical 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.

RECOMMENDED "TIPS" FOR CLEANING STAINLESS STEEL
WARNING: ELECTRIC
SHOCK HAZARD
Unplug the unit from
electric power before
performing cleaning or maintenance.
WARNING: ELECTRIC
SHOCK HAZARD
DO NOT spray or splash
water on the control panel
or wiring.
CAUTION: CART

Do not tip cart onto the
doors to drain excess
water. Permanent damage to the
doors and hinges will result. Use a
clean dry cloth to mop any excess
water inside cabinet after cleaning.

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. PHF freezers
are capable of cooling to a temperature of 0°F (-18°C). Pre-cooling time to
0°F (-18°C) is approximately 40 minutes. Only product that has been pre-
chilled should be placed into the cabinet. Placing warm product will ele-
vate 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 temperature,
high frequency of tray activity and excessively long operations, the door
may need to be closed so the unit can recover to proper operating tem-
perature.
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 op-
erating temperature has been reached (34°-40°F for refrigerators, 0°F
for freezers). Power light will illuminate when switch 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 tempera-
ture maintenance time.
Remember: the refrigerator or freezer 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
prevent water spills, leave the unit plugged in, with the door closed for at
least 90 minutes after use.

THERMOMETER CALIBRATION
Place an oven thermometer in the center of the cabinet. Turn heater on; turn
thermostat to maximum setting and wait approximately 45 minutes. Open the
door and check inside thermometer temperature. If recalibration is required,
pry the plastic cover off the dial body and with a small flat blade screwdriver,
insert into the pointer as shown. Carefully turn the pointer with your finger to
the correct setting. Be careful not to bend the pointer. It is very fragile.

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 lubricated 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 situa-
tions.
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 wash-
ers if the are removed when cleaning doors and hinges. If doors are re-
moved for cleaning, we recommend 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. Lubri-
cate latches regularly with WD-40, silicone spray, graphite or other commer-
cial 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.
