The Belshaw’s Insider™ (Donut Frying System) comprehensively addresses all fire
prevention, clean air, sanitation and electrical requirements and the self-contained unit
meets or exceeds local standards. The Insider houses one of the following Donut Robot
Fryers; MKII, MKV or MKIX and is UL197 Listed under ETL #68183.
• Tested to UL197 standards for Commercial Electric Cooking Appliances with
Recirculating Systems and Listed under ETL #68183.
• Intended for installation and use to NFPA-96 Standard For Ventilation Control
and Fire Protection of Commercial Cooking Operations.
Fire Prevention/ Suppression System
The Insider™ uses the Pyro-Chem Restaurant Fire Suppression System. It is a preengineered type as defined by NFPA-17A Standard for Wet Chemical Extinguishing
Systems and is designed to provide fire protection for restaurant cooking appliances,
hoods, and ducts.
The Pyro-Chem System (PLC-240/300 KITCHEN KNIGHT II) utilizes a wet chemical
agent specifically designed to suppress restaurant-cooking fires. The system
provides automatic actuation and can be manually actuated through a remote
mechanical pull station. Upon actuation, the system discharges a pre-determined
amount of agent to the duct, plenum, and cooking appliances. The agent acts to
suppress fires in 3 ways:
• Both the agent itself and the resulting steam formation interrupt the chemical
chain reaction causing combustion.
• The agent cools the fire bringing it below auto-ignition temperature.
• The agent reacts with hot grease forming a soap-like layer (saponification)
that helps prevent the escape of combustible vapors, thus preventing reignition.
The Pyro-Chem Restaurant Fire Suppression System has been tested to the UL
Standard for Fire Extinguishing Systems For Protection of Restaurant Cooking
Areas, UL300 and Pyro-Chem listed by Underwriters Laboratories, Inc. under
ULC/ORD-C1254.6-1995 listing meets Underwriters Laboratories of Canada’s
standards.
Clean Air- Ozone and Emissions
The Insider™ meets the emission requirements of 5.0mg/m3 as measured at the
exhaust outlet of the system per the requirements of the U.S. Environmental Protection
Agency (EPA) Test Method 202, Determination of Condensable Particulate Emissions
from Stationary Sources, which is referenced in NFPA-96 (Test results 1.81 mg/m3) UL
File E213302.
Underwriters Laboratories also tested it at well below the maximum ozone levels
permitted of 0.1ppm time-weighted average with a maximum peak concentration of
0.3ppm (Test results less than 0.015 ppm).
Sanitation
The Insider™ is built in accordance with NSF International Standard No. 4, for
commercial cooking and hot food storage equipment and conforms to ANSI/NSF STD 4
(ETL Listing #68183).
The fryer portion, Donut Robot Mark II, Mark V, or the Mark IX, is separately ETL
Classified in accordance with NSF International Standard No. 4. One of the above
models is used in each Insider™:
Materials employed have been found to be able to withstand normal wear, penetration of
vermin, corrosive action of foods, cleaning products, and other elements in the end use
environment. The materials do not impart an odor, color, taste, or toxic material to food
products.

Instructions
1. Put the air cleaner cell on the lower rack of
the dishwasher with the airflow arrow
pointing up. It maybe necessary to remove
the upper rack. Don't block water flow to
the upper arm, if provided on your
dishwasher.
2. If you are washing the pre-filter and grease
filter with the cell, place them where they
won't block the water from the electronic
cell.
Hand Washing Instructions
Note: Always wash the air cleaner cell first,
then the pre-filters. This will help keep heavy
lint on the pre-filter from getting caught in the
cells.
Wash the cell and filters as follows:
1. Use a container large enough to hold the air
cleaner cell, such as a laundry tub or trash
container.
2. Dissolve about 3/4 cup of automatic
dishwasher detergent in enough hot water to

down a few times, and remove.
4. Next, wash the pre-filter and grease filter the
same way. Empty and rinse the wash
container.
5. Rinse the cell, pre-filters and grease filter
with a hard spray of very hot water, rinse the
tub clean, and then fill the tub with clean hot
water and soak for 5 to 15 minutes. Rinse
3. Using the detergent that works best for
normal dishwashing, allow the dishwasher to
run through the complete wash and rinse
cycle. Do not use the dry cycle. To avoid
burns, wear protective gloves when
removing the cell, or let it cool first.
Remember that water maybe trapped in the
tubes supporting the collector plates. Tip the
cell so these tubes can drain.
4. Inspect the dishwasher. You may wish to
rerun the wash and/ or rinse cycle with the
dishwasher empty if you see dirt or residue
from washing the cell. If dirt or residue
seems excessive, wash the cell more often or
try a different detergent.
WARNING
Allow the cell to cool or wear protective
gloves to avoid burns. Hot water may
accumulate in the tubes supporting the
collector plates. Tip the cells so these
tubes will drain.
5. Wipe the ionizer wires and red contact board
with a clean cloth.
6. Reinstall the filters and air cleaner cell.

factory test pressure or the test pressure specified
by the manufacturer. No leakage or rupture shall
be permitted. The test procedure shall be in
accordance with the manufactures’ detailed
written hydrostatic test instructions.
Exception:
Containers bearing DOT or TC markings shall be
tested or replaced in accordance with the
appropriate DOT or TC requirements.
Wet chemicals removed from the containers
prior to hydrostatic testing shall be discarded.
To protect the hazard during hydrostatic testing,
if there is no connected reserve, alternate
protection acceptable to the authority having
jurisdiction shall be provided.
c) Pipe and Nozzle Installation
All pipe ends shall be thoroughly reamed after
cutting and all oil and foreign matter removed
from the pipe. It is recommended that the
following procedures be followed:
1. Disconnect and remove discharge piping
from the inside.
2. Make certain that all threaded ends and pipe
are clean and the pipe is free of foreign
matter and oil.
3. Apply Teflon tape on threaded ends. Start at
the second mail thread, wrapping the tape
clockwise around the threads, away from the
pipe opening.
4. Do not over tighten, but be sure the pipe is
snug. Do not back-off sections of pipe to
make them fit better.
All piping shall be securely fastened to pipe
hangers. A union is installed in the discharge
piping close to the cylinder valve, to permit
disconnection and removal for inspection and
service. Dry air or nitrogen should be blown
through the discharge piping to remove chips and
other debris prior to installation of nozzles.
Nozzles shall be installed in accordance with the
limitations described in this manual. Blowoff
caps are provided for each nozzle. These will
prevent dirt and grease from clogging the nozzle.
d) Fusible Link Detector
Installation
After mounting the cylinder and control head, the
fusible link line can be installed. The first step
to installing the fusible link line is to install the
detector bracket(s). These brackets must be
installed in the plenum area of the ventilation
hood over all protected Mark II, V, or IX Fryer
and in each duct.
Note: Only FL-212 Fusible Links can be used.
Connect the fusible link brackets together using
1/2” conduit and the conduit connectors supplied
in the detector kit (Model FLK-1/1A). A PyroChem corner pulley must be used whenever a
change in conduit direction is necessary. The
conduit is connected to the control head through
a knockout in the upper left-side corner.
In general, fusible links centered in the detector
brackets are connected in series using 1/16”
diameter stainless steel cable. The spring plate in
the control head maintains tension on this series
of fusible links.
Fusible links are always used in conjunction with
the Model NMCH Mechanical Control Head.
If the tension is released for any reason (i.e., a
fusible link separates), the control head will
operate and actuate the system. Maximum
limitations for the fusible link detection line are
as follows:
Fusible links can be installed with or without
fusible link hangers.
1. Fusible Link Installation Without
Hangers
Begin installing links at the terminal bracket.
The link is connected to the far side of the
terminal bracket using an “S” hook. The “S”
hook must be crimped closed after the link is
installed. A tight loop is then made in the cable
and secured by the crimp provided. This loop is
connected to the other side of the terminal link
(see Illustration E) and the cable fed through the
conduit to the next bracket.
After the last link in the series is connected, the
cable should be fed through the conduit back to
the control head. Thread the cable through the
hole in the fusible link ratchet wheel. The line
must then be crimped, and the crimp positioned
inside the center of the ratchet wheel.
NOTE
Illustration F
Fusible Line Link Termination
2. Fusible Link Installation Using Model
FLH-1 Fusible Link Hangers
Beginning at the control head feed the stainless
steel cable through the conduit and brackets to
the terminal bracket in one continuous length.
Allow approximately two and one half (2.5)
inches of slack at each bracket for the installation
of he Fusible Link Hangers. At the terminal link,
a tight loop is made in the cable and secured by
the crimp provided. The cable is attached to the
far side of the terminal bracket using an “S”
hook. The “S” hook must be crimped closed
after the cable is installed. See Illustration G.
Crimps must always be used in
conjunction with two (2) cable lengths.
Loops are the accepted method of
connecting the cable to mechanical
components. The crimp must never be
used on a single cable.
The fusible link line can now be put into a set
position by applying tension to the fusible link
line. This is accomplished by using 3/4” socket
on the fusible link line ratchet wheel. The
ratchet wheel will be ratcheted in a clockwise
direction until the spring plate makes contact
with the top of the control head box. The fusible
link line is now in a set position.
See Illustration F
Illustration G
Terminal Bracket Connection
Begin installing the Fusible Link Hangers at the
terminal bracket and work toward the control
head. Loop the cable through the oval opening
in the hanger and hook the fusible link on the
loop. See Illustration H
Hook the bottom of the link onto the bottom leg
of the hanger. See Illustration I
NOTE
Crimps must always be used in
conjunction with two (2) cable lengths.
Loops are the accepted method of
connecting the cable to mechanical
components. The crimp must never be
used on a single cable.
The fusible link line can now be put into a set
position by applying tension to the fusible link
line. This is accomplished by using a ¾” socket
on the fusible link line ratchet wheel. The
ratchet wheel will be ratcheted in a clockwise
direction until the spring plate makes contact
with the top of the control head box. The fusible
link line is now in a set position. See Illustration
F. Check to ensure that the fusible link hanger(s)
remain centered in the bracket after the fusible
link line is set. See Illustration J.
Illustration I
Fusible Link/Hanger Connection
Center the hanger/link in the fusible link bracket
by sliding it along the link line. This is easily
accomplished before any tension is applied to the
link line. Repeat this procedure for all fusible
links.
After the last hanger/link in the series is
connected, the cable should be fed through the
hole in the fusible link ratchet wheel. The line
must then be crimped, and the crimp positioned
inside the center of the ratchet wheel.
Illustration J
Fusible Link/Hanger In Set Position
e) Setting the Control Head
Model NMCH Mechanical Control Head
Once the fusible link line is set, the control head
can be placed in the set position. To set the
control head, the slide plate is moved from right
to left, ensuring the bolt extending from the cam
arm is in the slot provided in the slide plate.
Continue moving the slide plate to the left until
the latching arm is in the locked position. Insert
the pull pin into the hole in the slide plate above
the latching arm. This will lock the control head
in the set position, eliminating accidental
actuation during the rest of the installation
procedure. See Illustration K

Miniature Switch Installation
f) Remote Pull Station
Installation
The model RPS-M Remote Mechanical Pull
Station is used for remote mechanical actuation
of all system releasing devices. It is to be located
near an exit in the path of egress from the hazard
area no more than five feet above the floor.
NOTE
A Model RPS-M Remote Mechanical Pull
Station must be used for manual
activation of a Model EN-MCU or a Model
NMCH releasing device.
The Pull Station can be surface mounted or flush
mounted. For flush mounting a RACO #232, 4”
deep electrical box or equivalent must be used
(dealer supplied). It is connected to the releasing
device using 3/64” or 1/16” diameter stainless
steel cable. The cable enters the pull station box
through the center hole in the bottom, top, either
side, or the center back hole. The cable enters
the control head through the top center knockout.
The cable must be enclosed in 1/2” conduit with
a Pyro-Chem corner pulley at each change in
conduit direction.
After mounting the pull station box and conduit,
feed the stainless steel cable from the releasing
device, through the conduit, and into the pull
station box. Feed the cable through the bushing
and through the hole provided in the pull handle.
Loop the cable through the pull handle an secure
it with the crimp provided. See Illustration L.

g) System Checkout After
Installation
Model NMCH Mechanical Control Head
Before putting the system into service, all
components must be checked for proper
operation. During this checkout, assure that the
carbon dioxide pilot cartridge is not installed in
the control head actuator. Remove the pull pin
from the hole in the slide plate.
To check satisfactory operation of the control
head, cut the terminal link or the “S” hook
holding the link. This will relieve all tension on
the fusible link line and operate the control head.
The slide plate will have moved fully to the right.
Any auxiliary equipment connected to the dry
contacts of the Miniature Switch in the control
head will have operated.
If any of these events fail to occur, the problem
must be investigated and repaired.
Repair the terminal link and put the fusible link
line back into the set position. This is
accomplished by using a 5/8” socket on the
fusible link line ratchet wheel. The ratchet wheel
will be ratcheted in a clockwise direction until
the spring plate makes contact with the top of the
control head box.
Once the fusible link line is set, the control head
can be placed in the set position. M To set the
control head, the slide plate is moved from right
to left, ensuring the bolt extending from the cam
arm is in the slot provided in the slide plate.
Continue moving the slide plate to the left until
the latching arm is in the locked position.
Once the control head is set, pull the pull handle
on the remote pull station to assure that the
control head operates. If the control head
operates normally, the control head can be reset
as described above.
CAUTION
Before screwing the carbon dioxide pilot
cartridge into the actuator, ensure that
the actuator has a Teflon O-ring installed.
Using a felt-tipped marker, write the date of
installation in the gray area of the carbon dioxide
pilot cartridge. Screw the cartridge into the
control head actuator until hand-tight. Never use
a wrench to tighten the cartridge into the
actuator.
Remove the pull pin from the hole in the slide
plate and install the control head cover.
Fire Damper System
Visually inspect the damper or damage and
verify that the fusible link is in place between the
two couplers as shown in Illustration M.
Illustration M
Fusible Link Location
If the fusible link is not present or there are any
signs of damage during the inspection:
DANGER
To avoid causing death or serious bodily
harm to building occupants, make sure
all damper corners are square and the
damper has not been damaged. Do not
install any damper which is deformed or
damaged.
Note: Maintain the UL approval by ordering a
replacement fusible link from Johnson
Controls before continuing.
DANGER
To avoid causing death or serious bodily
harm to building occupants, never install
a fire damper without the proper UL
approved fusible link in place.
Use the following fusible link:
For code FOVHN (212° F) use replacement
fusible link DMPR-RF002.
After you receive the new fusible link:
1. Place the fusible link on the coupler from
the bracket shown in Figure 3-9. Use long
needle-nose pliers to hold fusible link in
position.
location on the jackshaft or use a 1/2” openend wrench on the end of the drive shaft.
3. Rotate the jackshaft in a clockwise direction
until the other coupler post is in position and
install the fusible link onto the post.
4. Slowly reduce pressure on the pipe wrench
until slack is taken up by the fusible link.
WARNING
The damper must be armed. It is shipped
with the safety pin installed.
CAUTION
Do not put hands or fingers into the fire
damper. It is spring-loaded and bodily
harm could result.
Carbon Filters
The carbon filters are 1-3/4 inches by 11-1/2
inches by 19-1/2 inches. The INSIDER requires
the use of two (2) filters. The carbon filters
should be replaced every six (6) months.
The washing frequency best suited for you unit
can be determined by examining the dirt
collected components at three (3) week intervals.
As the dirt begins to collect, you will notice a
light film, then a very definite collection will be
evident at a later examination. When there is a
noticeable build-up of dirt, it is time to wash.
In most areas the collecting cell should be
washed about every twelve (12) weeks.
Note: Dirt build-up on the ionizing-collecting
cell should not be confused with dirt
stains. Dirt stains are normal and do not
affect efficiency.
Steps for Washing:
1. Switch control switch “OFF”.
2. Remove pre-filter and cell.
3. Place components in automatic dishwasher,
stationary tub, shower stall or over floor
drain. Use hot soapy water and rinse
thoroughly. As an aid to drying, rinse with
clear, hot water. Allow components to dry
thoroughly.
Note: Ionized wires are easily broken. Handle
the cells with care.
4. Replace pre-filter and cell.
5. Close cell access door.
Electronic Air Cleaner
Maintenance and Washing
When to Wash:
Periodically the dirt collected by your unit must
be removed. The frequency of washing will
depend on the amount of dirt present in the air in
you locality.
If arcing noise occurs due to wet cells, turn
switch off and allow more drying time.
If there are any problems, refer to the service
checklist.

Electronic Air Cleaner (air cleaner cell)
not installed or locked in place.
Carbon Filter not installed or contacting
interlock disc.
Install two (2) carbon filters in the slide
tray. Make sure that they contact the
interlock disc behind the filters. The
door pushed the filters back against the
disc when it is latched. The disc can be
adjusted in or out by turning the disc. If
the disc is too loose put Loctite on the
threads. The interlock switch can be
adjusted from inside the electrical
enclosure.
Air pressure differential switch not
adjusted properly or obstruction in
filters/air flow.
1. Hold the “Start button” in for a few
seconds to attain proper air flow.
2. Check, clean or replace filters.
3. Check to see if reed switch is stuck.
Tap on switch housing.
4. Check differential adjustment screw
located under pressure switch cover,
inside upper electrical enclosure.
Approximate setting is 2-1/2 turns
clockwise with N.O. contacts.
Cell relay interlock is not latching in. 1. Hold the “Start button” in for a few
seconds to allow for latching time.
2. Check fuse labeled filter and replace.
3. Check for loose connections and
power to relay.
4. Replace relay.
The fire damper is closed The damper fusible-link has activated
the damper. Replace the fusible-link
and reset the damper. Temperatures
over 212° F will release the damper.
Also old or damaged fuse-links may
allow damper to close.
When an arcing noise is noted, it is usually
located in the DC high voltage circuit. The
ionizing-collecting cell is part of this circuit and
normally the trouble will be found to be in the
cell. The noise is caused by high voltage arcing
to ground.
An occasional arcing noise is normal and
inherent in all precipitators. These occasional
arcs are caused by large particles of dirt in the air
such as a cigarette ash, insect, etc. Constant or
repeated intermittent arcing should be checked.

A hissing noise (or frying sound) usually stems
from a loose high voltage connection or from an
improper ground. The reduction in the designed
spacing usually is caused by bends or deformities
in the cell from mishandling.

4. Ozone
Under normal operating conditions all
electrostatic air cleaners produce minute
quantities of ozone as an incidental by-product,
as do televisions and other electrical appliances.
The design of the unit has been tested and is far
below the published permissible limits. The
level of detection (when it is noticed) varies from
individual to individual, some being more
susceptible than others. Usually a new unit will
produce more ozone than one that has been in
operation for several weeks. This is due to the
normal amount of sharp corners or
manufacturing burrs on the ionizing-collecting
cell. The voltage working on these areas
however, tends to round them off, thereby they
are self-correcting.
An ionizing-collecting cell that has been
damaged, where the designed spacing between
electrically charged and ground components has
been decreased, may also produce an abnormal
amount of ozone.
3. Humming Noise
The ionizing wires have a normal tendency to
vibrate when charged. On some occasions when
atmospheric conditions are just right and the
humidity is exceptionally low, the vibration is
aggravated to the point where and audible hum
can be noted. It is usually noted more in the
northern sections of the country during the winter
months. This condition can be further
aggravated if the ionizing-collecting cell is very
dirty. The condition is self-correcting when the
relative humidity is increased or can be alleviated
by washing the cell.
Radio and/or Television Interference
This trouble is not common but when occurring
is usually due to either a continuous high voltage
“leak or discharge”, or from the absence of a
good common electrical ground. Refer to checks
listed under 1. Arcing Noise and 2. Hissing
Noise.
Check for:
a. Damaged (bent) plates – straighten or
replace.
b. Loose ionizing wires – repair or replace
c. Dirty cell – clean
d. Loose high voltage connections – repair or
replace.

Exercise usual precautions when
working with high voltage. When circuit
has been de-energized always discharge
any residual current in the secondary
with an insulated handle screwdriver.
Always ground power supply and
ionizing-collecting cell when bench
testing.
Ionizing-Collecting Cell
The cell is electrically energized through a
contact terminal located at the top center of the
cell. The ionizing wires and every other
collector plate are electrically charged while each
interleaving plate is ground. Most trouble in the
cell can be readily detected visually.
System Check
A simple system check can be made by drawing
an arc as follows:
Remove pre-filter and cell.
Remove pre-filter from cell.
Re-install cell without pre-filter.
Use screwdriver to energize safety switch. If
high volt meter is not available proceed as
follows:
Use an insulated screwdriver to draw an arc
between extended ground plate an ionizing wire.
A sharp electrical arc of approximately 1/4”
should be observed. This indicated proper cell
operation. If weak arc or no arc is observed,
follow cell and power supply checkout.
If using high volt meter, voltage should read
between 5.9 – 6.5 kilovolts. If voltage is below 6
kilovolts or no output at all, the problem lies in
either the cells or power supply. See Electronic
Air Cleaner - Troublechart, page 24.
If there is primary power to the power supply and
the secondary output voltage is absent or very
low, the power supply is defective. Drawing an
arc, with an insulated handle screwdriver
between common ground and the high voltage
output terminal (c) can make a simple check. A
good power supply will produce a pronounced
arc where a defective one will produce no arc at
all or a very weak one.
(Refer to illustration “N” Trouble shooting
Trion-power supply).
Power Supply Check (with DC high volt
meter).
Take reading with the high voltage meter at cell
contact point. Voltage should read 7 kilovolts or
higher (without cell connected). If voltage is
above 7 kilovolts, the problem is in the cell (see
cell checkout procedure). If voltage is below 7
kilovolts (without cell connected), the problem is
in the power supply.
Proceed as follows:
Remove power pack from the unit.
Check for loose wires; if loose wire found,
reconnect.
Fires can potentially start in a cooking appliance, the hood, or the duct. In case of fire, it is important that
you fully understand the operation of your fire suppression system.
1. Evacuate all personnel and customers from the fire area.
2. If your fire control system has not already automatically activated, you may activate it manually by
pulling the handle on the silver manual pull station, located at the back of the Insider to the right of
the red fire extinguisher cylinder.
3. Call the fire department.
4. Personnel trained in the proper operation of hand portable extinguishers may stand by if means of
easy exit are available.
When the fire has been extinguished, call your authorized Pyro-Chem distributor to recharge the system,
after determining the cause of fire. Under no circumstance should cooking operations be attempted before
qualified personnel re-instate the integrity of your fire suppression system.
