Site Preparation
Choose a well-ventilated location with a minimum clearance of
two feet (2’) from all sides of the unit. Place the holding station
on a suitable table or counter capable of supporting the weight
of a fully loaded holding station. The power supply must be in
accordance with the specifications on the data plate located on
the rear of the appliance. It should be installed on a dedicated
service line with no other equipment on the circuit. The unit
must be positioned so that the unit’s plug is accessible. (If
the power cord is damaged, it should only be replaced by the
manufacturer or an Authorized Service Agent.)
Operation
CAUTION
CAUTION
The operator of this equipment is solely responsible for ensuring safe holding temperature levels for all food items.
Failure to do so could result in unsafe food products for customers.
Failure to follow the operating and cleaning instructions could cause grease build-up which may result in a decrease
in food quality.
The airflow and temperature of the Merco Fried Food Station is factory pre-set for optimum holding time for all fried
foods. No adjustment of airflow or temperature is required.
1. Verify the grease pan and salt trays are installed properly.
2. Adjust dividers to desired location. First, lock in lower tab near the rear of the salt tray then pivot downward until all tabs are
locked into place.
3. Turn power to the “ON” position. “I” = ON, “O” = OFF.
4. Allow for a 20-minute preheat.
When scooping food product from the appliance, work in a front-to-back motion so as to avoid possible grease
build-up in the air-intake holes located in the front of the unit.
CAUTION
7
Maintenance
The following cleaning instructions must be carried out to
ensure satisfactory performance of your Fried Food Holding
Station. Neglecting to follow these procedures may result in
reduced holding times, reduced reliability and may void the
warranty.
CAUTION
WARNING
Never hose down interior or exterior of units with
water. This will void the warranty. Wipe interior dry
of any water accumulation.
Never unplug the unit before cool-down is complete
as this will bypass an important safety feature and
may cause injury. Always allow unit to cool down
prior to disconnecting from power source.
Daily Cleaning
1. Upon completion of the last holding cycle of the day,
remove dividers, salt tray and grease pan.
2. Wash components with soapy water.
3. Use a soft cloth or sponge, dampened with warm soapy
water, to wash the interior and exterior of the appliance.
Airflow openings should be inspected and any blockage
should be removed. Note: Do not flood the appliance with
cleaning fluid!
CAUTION
When cleaning interior and exterior of unit, care
should be taken to avoid the front power switch and
the rear power cord. Keep water and/or cleaning
solutions away from these parts.
4. Rinse using a cloth dampened with clear water, then dry.
5. Install pans, trays and dividers.

Stainless Steel Care and Cleaning
Stainless steel contains 70- 80% iron, which will rust. It also
contains 12-30% chromium, which forms an invisible passive
film over the steel’s surface, which acts as a shield against
corrosion. As long as the protective layer is intact, the metal
is still stainless. If the film is broken or contaminated, outside
elements can begin to breakdown the steel and begin to form
discoloration or rust. Proper cleaning of stainless steel requires
soft cloths or plastic scouring pads.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
Cleaning solutions need to be alkaline based or non-chloride
cleaners. Any cleaner containing chlorides will damage
the protective film of the stainless steel. Chlorides are also
commonly found in hard water, salts, and household and
industrial cleaners. If cleaners containing chlorides are used be
sure to rinse repeatedly and dry thoroughly. Routine cleaning
of stainless steel can be done with soap and water. Extreme
stains or grease should be cleaned with a non-abrasive cleaner
and plastic scrub pad. Always rub with the grain of the steel.
There are stainless steel cleaners available which can restore
and preserve the finish of the steel’s protective layer. Early
signs of stainless steel breakdown are small pits and cracks.
If this has begun, clean thoroughly and start to apply stainless
steel cleaners in attempt to restore the passivity of the steel.
CAUTION
Never use an acid based cleaning solution! Many
food products have an acidic content, which can
deteriorate the finish. Be sure to clean the stainless
steel surfaces of ALL food products. Common items
include, tomatoes, peppers and other vegetables.
Maintenance, continued
Steps For Component Removal
Weekly Cleaning
1. Remove dividers.
The air intake vents (interior, rear and front vents) should be

Sequence Of Operation
Power Supply
Electrical power is supplied to the unit by a 3 conductor service for single phase.
Black conductor is hot.
White conductor is neutral.
Green and yellow conductor is ground.
Power is permanently supplied to one of the normally open contacts of the main switch also to one
side of the normally open contacts of the main heater relay.
Heating Circuit
Closing the main power switch feeds power through the normally closed high limit thermostat to
the coil of the main relay. Its contacts now close supplying power to the main heater. Also for air
circulation power is supplied to the main fan motor.
