Installation
Oven Description and Specifications
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.
Blodgett ovens are quality produced using high grade
stainless steel with first class workmanship.
The multiple speed fan, which is guarded against accidental finger 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.
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.
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.

Maintenance
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.
NOTE: Further information can be found in the instruction
leaflet supplied with your spray bottle.
WARNING!!
Protective clothing and eyewear should be
worn while using cleaning agents.
1. Unscrew the sprayer head and fill the container to
the MAX mark. Screw the head assembly on firmly to
ensure an airtight seal. The liquid must be clean and
free from foreign matter. Do not overfill - space must
be left for compressing air.
Pressure Pump
Spray Trigger
Spray Head
2. To build up pressure, pump approximately 20 full
strokes when the container is filled with liquid. The
higher the pressure, the finer the spray. If the container is only partially filled, then more pumping is required to compress the additional air space.
Pump
3. To spray, depress the trigger with your thumb.
Pressure
Vessel
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.
Clean the pump 2 or 3 times per week with warm water
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 filling aperture.
Figure 13
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.

Cleaning and Preventive Maintenance
CLEANING THE INTERIOR
Daily Cleaning
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.
Daily cleaning of the appliance is essential for sanitation,
and to ensure against operational difficulties. 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 difficult cleaning, allow the spray-on oven cleaner to
work longer before rinsing.
NOTE: DO NOT use corrosive cleaners not intended for
oven cleaning on your oven.
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.
Recommended cleaners:
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.

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

Cleaning and Preventive Maintenance
Oven Weekly Cleaning
5. Thoroughly spray cleaner onto the fan and heat
source. Close the doors to allow the cleaner to work.
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 efficient oven.
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.
1. Turn off the oven. Make sure that the oven is cooled
down to under 140°F (60°C).
Remove and clean the blower wheel every 6 months.
2. Remove the rack guides.
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.
CLEANING THE EXTERIOR
3. Rotate the two screws on the left side of the fan guard.
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.

Maintenance
Sequence of Operation
When the Control is first 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:
Light
Cook Done
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.
Vent
Cooling Fan
Hot Air
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 [email protected] or [email protected] Speed Relay, which is 24 VDC return at the grey wire in J11.4.
Hot Air
Enable
Hot Air
Contactor
D35 LED shows the Hot Air Enable relay is activated when
the [email protected] 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.
Spritzer
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.

Maintenance
Sequence of Operation
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.
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).
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
return is High Speed, and 23 VDC return on J2.9 and
J2.10 is Turbo Speed.
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.
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.
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.
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.
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.
