Installation

Oven Description and Specications

Blodgett ovens are quality produced using high grade

stainless steel with rst class workmanship.

The multiple speed fan, which is guarded against acci-

dental nger contact, is driven by a quiet and powerful

motor. The condenser draws out excess moisture from
the appliance. Condensation and waste water, which re­sult during hydro cooking and cleaning, are continuously
drained.

The use of high quality insulation impedes excessive heat
radiation and saves energy.

The HV-100EM has legs which adapt easily to slightly un­even surfaces.

The practical oven doors, with viewing windows, have a
wide swing radius and handle which can be operated eas­ily, even with wet or greasy hands.

Ease of operation is guaranteed through the simple ar­rangement of the controls. Graphic symbols make the ap­pliance easy for even inexperienced kitchen staff to oper­ate. The Cool Down mode, allows the oven cavity to cool
down rapidly with the door opened.

Cleaning is kept to a minimum. The interior is sprayed
with a self-acting cleaning solution which interacts with
humidity to easily remove crusts and stains. The oven is
designed for easy care and is welded water tight so that
the internal cooking cavity may be rinsed with a hose after
the cleaning process.

VENTILATION

The necessity for a properly designed and installed ven­tilation system cannot be over emphasized. The ventila­tion system will allow the unit to function properly while
removing unwanted vapors and products of combustion
from the operating area.

The appliance must be vented with a properly designed
mechanically driven exhaust hood. The hood should be
sized to completely cover the equipment plus an over­hang of at least 6” (15 cm) on all sides not adjacent to a
wall. The capacity of the hood should be sized appropri­ately and provisions made for adequate makeup air.

WARNING!!

Failure to properly vent the oven can be haz­ardous to the health of the operator; and will
result in operational problems, unsatisfactory
baking, and possible damage to the equip­ment. Damage sustained as a direct result of
improper ventilation will not be covered by the
Manufacturer’s warranty.

Installation

Ventilation

When installed in the Commonwealth of Massachusetts,
this appliance must be interlocked with the hood exhaust
system so that the appliance may be operated only when
the hood exhaust system is running.

U.S. and Canadian Installations

Refer to your local ventilation codes. In the absence of
local codes, refer to the National ventilation code titled,
“Standard for the Installation of Equipment for the Remov­al of Smoke and Grease Laden Vapors from Commercial
Cooking Equipment”, NFPA-96- Latest Edition.

General Export Installations

Installation must conform with Local and National instal­lation standards. Local installation codes and/or require­ments may vary. If you have any questions regarding the
proper installation and/or operation of your unit, please
contact your local distributor. If you do not have a local
distributor, please call Blodgett at 0011-802-658-6600.

Spray Bottle Operating Procedure

NOTE: Only use a commercial oven cleaner/degreaser

with the spray bottle. DO NOT use chemicals that
are not intended as oven cleaners. See chemical
manufacturer’s information for intended use.

1. Unscrew the sprayer head and ll the container to
the MAX mark. Screw the head assembly on rmly to

ensure an airtight seal. The liquid must be clean and

free from foreign matter. Do not overll - space must

be left for compressing air.

2. To build up pressure, pump approximately 20 full

strokes when the container is lled with liquid. The
higher the pressure, the ner the spray. If the con­tainer is only partially lled, then more pumping is re-

quired to compress the additional air space.

3. To spray, depress the trigger with your thumb.

4. Adjust spray nozzle for a wide spray pattern.

5. After a period of spraying, the pressure will drop. Re­store the pressure by operating the air pump.

6. Release pressure after use by inverting the spray
head and depressing the trigger or by slowly un­screwing the spray head assembly which will allow

air to escape from around the lling aperture.

7. After use, rinse the spray bottle with clean water and
check that the hole in the nozzle is perfectly clean and
clear. Warm water (not hot) used with a household
detergent is a useful cleaning agent for this purpose.

NOTE: Further information can be found in the instruction

leaet supplied with your spray bottle.

WARNING!!

Protective clothing and eyewear should be
worn while using cleaning agents.

CLEANING THE INTERIOR

Daily Cleaning

Daily cleaning of the appliance is essential for sanitation,
and to ensure against operational difculties. The stain­less steel cavity may corrode with improper cleaning of
the oven. Use an oven cleaning detergent in conjunction
with the supplied spray bottle.

For difcult cleaning, allow the spray-on oven cleaner to

work longer before rinsing.

1. Cool the appliance down to 140°F (60°C) or, if the
oven has been idle, turn to the Steam mode for 3 to 4
minutes in order to warm the cavity surfaces.

Maintenance

Cleaning and Preventive Maintenance

On stainless interiors, deposits of baked on splatter, oil,
grease or light discoloration may be removed with a good
non toxic industrial stainless steel cleaner. Apply cleaners
when the oven is cold and always rub with the grain of
the metal. The racks, rack supports and the blower wheel
may be cleaned in the oven or by removing them from the
oven and soaking them.

NOTE: DO NOT use corrosive cleaners not intended for

oven cleaning on your oven.

Recommended cleaners:

• ECOLAB Greasecutter Plus

2. Fill the spray bottle and pump air into the container
with the pressure pump.

3. Spray the interior of the oven with a cleaning solution.
Be certain to spray cleaner through the fan guard to
cover all surfaces.

NOTE: Never spray water into the appliance when

the temperature is above 212°F (100°C).

4. Let the cleaner work the time recommended by the

cleaning solution manufacturer. For difcult, baked on

grease, etc. allow to work over night.

5. Set the timer for 15 to 20 minutes.

6. Run the oven at 225°F (107°C) in the Steam mode.
This will soften all burned on residue.

7. Rinse the appliance interior with water (a hose is
supplied, but take care that only the interior cavity is
sprayed with water). Wipe the interior dry after rins­ing.

8. The doors should be kept slightly open after cleaning.
This will allow the oven to vent and increase the life
of the door gasket.

• CELLO EZ Clean

• Diversey-Lever Advance Oven Cleaner

WARNING!!

Be sure to read and follow the MSDS or
safety instructions on the bottle for your oven
cleaner.

Cleaning and Preventive Maintenance

Oven Weekly Cleaning

In addition to the daily cleaning, it is necessasry to clean
behind the fan guard of this oven on a weekly basis. This
is necessary for proper functioning of the oven. Scale will
build up on the fan and heat source leading to a less ef-

cient oven.

1. Turn off the oven. Make sure that the oven is cooled
down to under 140°F (60°C).

2. Remove the rack guides.

3. Rotate the two screws on the left side of the fan guard.

Figure 14

4. Remove the fan guard.

5. Thoroughly spray cleaner onto the fan and heat
source. Close the doors to allow the cleaner to work.

6. After ten minutes, rinse the cleaner off. Return the fan
guard to the closed position. Rotate the two screws to
secure the fan guard.

Remove and clean the blower wheel every 6 months.

CLEANING THE EXTERIOR

The exterior of the appliance may be cleaned and kept in
good condition with a light oil. Saturate a cloth and wipe
the appliance when it is cold; wipe dry with a clean cloth.

WARNING!!

DO NOT spray the outside of the appliance
with water or clean with a water jet. Cleaning
with a water jet can impregnate chlorides into
the stainless steel, causing the onset of corro­sion.

PREVENTIVE MAINTENANCE

The best preventive maintenance measures are the prop­er initial installation of the equipment and a program for
cleaning the appliance routinely. The oven requires no lu­brication. Contact the factory, the factory representative
or a local Blodgett service company to perform mainte­nance and repairs should they be required.

When the Control is rst turned on, it begins to Preheat

the oven to 350?F by enabling the following relays. The
activated relays are associated with red LEDs which will
turn on when the control sends a call to the relay. Relays
are designated with a K, LEDs are designated with a D,
and Junctions are labeled with a J. In preheat the follow­ing LEDs will be lit:

D25 LED will come on as the Light relay, K6, is closed.
The cavity lights will remain on until the Light button is
pressed to turn them off. Check for 24 VDC output at J3.4,
which feeds the cavity lights on the red wire.

D31 LED will be lit as the Hot Air (Power On) relay is
enabled on this unit. The Hot Air relay is active whenever
the red light is on at the Power Button. Check for 24 VDC
output from K3 at J6.4 on the orange wire, which jumps to
the common for the K2 relay at J6.7. The K2 relay waits
for input from the Fan@Speed or Drive@Set Speed Re­lay, which is 24 VDC return at the grey wire in J11.4.

D35 LED shows the Hot Air Enable relay is activated when
the Fan@Speed Relay is closed at the Inverter sending
24 VDC return in at J11.4; this signal closes K2. Check for
24 VDC output at J6.8 on the blue wire, which jumps to
J20.1. J20.1 is the common to the K1 relay.

D37 LED is lit as the Hot Air Contactor relay is enabled
when there is a Call for heat. A call for heat is generated
when the cavity probe(or core probe when not in preheat)
reads resistance/temperature below the current set point,
which is 350?F during preheat. Check for 24 VDC at
J20.2, which is the K1 relay output that feeds the contac­tor coil on the orange wire.

Also in preheat, the control will call for Fan High Speed
Forward by sending 23 VDC return on J2.10 and J2.11,
and 0 VDC on J2.9 and J2.12. Note: outside the ready
band, which is-10 to +25?F, in relationship to the set
point, the control automatically switches to high fan speed
and can be used only in high fan speed or turbo fan speed.
Once in ready band, all speeds are available.

Figure 16

Maintenance

Sequence of Operation

After preheat the control can be operated in Manual Mode
or in one of the 100 programs. Each program can have
up to 6 steps and a hold. In each step the user can pro­gram Core Probe (Yes/No), Cook Time, Mode (Steam/
Combi/Reth/Hot A), Set Temp, Fan Speed (Gentle/Low/
High/Turbo), Fan Reverse (Manual/Auto), Fan Reverse
Time, and Vent Setting (Close/Open).

If Core Probe is “Yes”, the unit will look for the resistance
at the probe port on the front on the control. If Fan reverse
is set to Auto, the control will automatically reverse the fan
every 2 minutes while a time counting down. If it is set to
manual, the reverse time can be set. Also the Cook Time,
Cook Mode, Set Temp, Fan Speed, as well as Vent posi­tion, can be programmed for each step. When the Vent
is opened, D24 LED lights and 24 VDC is sent by K5 on
the grey wire at J2.4; no voltage is present when the vent
is closed.

If operating in Manual Mode, you can manually modify
the Fan Speed, the Vent Position, Core or Cavity Probe,
Time and Temp, Steam on Demand (not functional in
steam mode) and the Cook Modes: Hot Air, Combi,
Steam, and Retherm.

Hot Air uses the “call for heat” sequence mentioned
above.

Combi uses the same call for heat and the Water Spritzer
is cycled at 33% for the default setting, or 20 seconds on
40 Seconds off. The cycle rate can be adjusted from 0 to
100%. When the Water Spritzer is called for, D33 is lit,
and K8 sends out 24 VDC on the Violet wire at J18.3.

Steam uses the same call for heat and the Spritzer is cy­cled at 100%. In steam the lowest temperature setting is
85?F and the maximum temperature in the steam mode
is 225?F. Steam on demand is not available in Steam
mode because the control is cycling the Spritzer at 100%
already.

Retherm uses the Water Spritzer at a 25% duty cycle, or
15 seconds on 45 Seconds off, and the call for heat is set
at 250?F as the default temperature. The Water Spritzer
cycle rate can be adjusted from 10 to 90% and the Tem­perature can be set to 250 - 300?F.

When the Control calls for the fan to go Forward, J2.11
will have 23 VDC return and J2.12 will have 0 VDC. That
condition will invert when the fan call is for Reverse; J2.12
will have 23 VDC return and J2.11 will have 0 VDC. The
speeds are set by J2.9 and J2.10. 0 VDC on both is Gen­tle Speed, J2.9 with 23 VDC return and J2.10 with 0 VDC
is Low Speed, J2.9 with 0 VDC and J2.10 with 23 VDC
re- turn is High Speed, and 23 VDC return on J2.9 and
J2.10 is Turbo Speed.

The Cooling Fan is controlled by the probe located under
the Inverter heat sink; it is cycled on at 100?F. When the
Cooling Fan is called for, K4 Relay sends 24 VDC out at
J3.11 on a grey wire, and the call is indicated by LED D26.
The Cooling Fan is also activated at any time the timer is
counting down.

Cook Done is not used. Therefore no wire is located at
J2.2, where K14 sends 24 VDC when D21 is lit. However,
Cook Done is activated when the Timer goes off on the
control.
