5. Maintenance
ENSURE YOU ARE WEARING INSULATED GLOVES AND AN APRON AT ALL TIMES WHEN WORKING
WITH THE HOT ROTISSERIE.
Allow a period of time for the rotisserie to reach a safe-to-touch temperature, but ensure that the oven
is still warm to facilitate easier cleaning.
Daily Cleaning
5.1.1 Beginning of the Day
Ensure that the entire unit is clean by referring to section 5.1.4 AutoClean Effectiveness Evaluation.If it is not
clean, perform an AutoClean cycle by following the on-site cleaning laminates or referring to section 5.1.3
Cleaning at the End of the Day: AutoClean Operation.
It is imperative that the rotisserie oven is properly clean and sanitized from the previous day. If an
AutoClean cycle was not run at that time, it must be run at the beginning of the day before a cook is
initiated.
5.1.2 Cleaning Throughout the Day
It is recommended to clean the inner glass with a soft, damp cloth after every cooking cycle. This will lead to
optimal cleaning results without scratching the glass. Avoid using scouring pads or cleaners with grit on glass.
If the heated grease collection reservoir is installed, monitor the liquid level throughout the day and
empty unit as required.

HARDT
Responsive, Reliable Solutions
Page 14 of 18 CUS-013-0025-02
5.1.3 Cleaning at the End of the Day: AutoClean Operation
It is recommended to run the AutoClean cycle at the end of the business day, after all cooking has been
completed.
Description of the AutoClean Operation
The AutoClean cycle consists of a succession of activities that are completely and automatically controlled by
the rotisserie. The sequence is as follows:
OVEN COOLDOWN: A period of time required for the rotisserie to reach a safe temperature for cleaning.
PREWASH: Fresh water is used for an initial flush of the drip pan.
SOAP WASH: involves the repeated application of a cleaning agent followed by soaking and draining.
FIRST RINSE: a rinsing cycle.
POWER RINSE: another, different type of rinsing cycle.
FINAL RINSE: a series of rinsing cycles involving water collection followed by draining.
Instructions for AutoClean
1. Verify that there is sufficient degreaser in the bottle to run
an AutoClean cycle. If the level is too low, replace the
bottle.
2. Open the door to the rotisserie.
3. Remove any large pieces that are left on the bottom of the
drip pan.
4. Using a wet towel, clean the front channel, exterior panel
and the inside door glass pane.
5. Rotate the Main Drain Valve Handle to CLEAN as shown
in Figure 5-1.
6. Close the rotisserie door and press CLEAN and then
ENTER to start the cleaning cycle. Read the display. If
the AutoClean has begun it will read either, “CHECKING
OVEN TEMPERATURE”, “CLEAN COOLDOWN” or
“PREWASH”.
Figure 5-1
If the display reads, “CLEAN COOLDOWN” the AutoClean will not start immediately as the cooking cavity
is too hot. DO NOT open the door to cool the rotisserie! It must cool on its own with the door closed
for optimal AutoClean performance and to avoid damaging the inside of the oven.
The AutoClean will start on its own when the unit has properly cooled.
For units equipped with the optional sensors –If the degreaser is low, an alarm will sound and the display will
show: “REFILL DEGREASER BOTTLE // PRESS CLEAN”. Replace the degreaser bottle and start again.
If the display shows: “CLOSE DRAIN VALVE // PRESS CLEAN”, the Drain Valve is not fully closed. Close it and
start again.
7. Clean the outside of the rotisserie following the convections outlined in 5.3 Material Cleaning Guidelines.

5.1.4 AutoClean Effectiveness Evaluation
It is important to consider the condition of the rotisserie after the AutoClean cycle is finished to verify that the
cleaning operations are functioning correctly. The following images illustrate three states of cleanliness and their
related interpretation.
COOKING IN AN OVEN WITH RESIDUE BUILDUP CAN CAUSE A FIRE
Figure 5-2: Dirty Cavity:
The image shows a cavity that has NOT been cleaned
sufficiently to cook in. This may be due to the cleaning
procedures not being followed on a consistent basis or the
AutoClean system having not functioning properly for an
extended period of time.
Figure 5-2
Figure 5-3: Mostly Clean Cavity:
It will be necessary to clean the rotisserie by hand using
regular oven cleaner (in a spray bottle) and a scrub pad or
scraper to remove the build-up of carbon prior to running the
AutoClean cycle. The AutoClean function will only clean the
grease from 1 day's worth of cooking. It may take a few days
of AutoClean and hand scraping to get the unit back to the
point where following the correct procedures will produce a
clean rotisserie in the morning.
If the rotisserie cavity looks like what is shown in Figure 5-3,
remove the residual flakes with a scrub pad PRIOR to
cooking.
Figure 5-3
Figure 5-4 Sufficiently Clean Cavity
Figure 5-4 shows a rotisserie cavity that is sufficiently clean
and in which cooking may be performed.

Weekly Inspection
Thoroughly inspect the venting components supplied with the rotisserie for signs of damage (dents, perforations,
etc). Replace with certified Hardt components if required. Ensure that the electrical cord, water and gas lines are
free from damage and kinks.
Material Cleaning Guidelines
5.3.1 Guidelines for Cleaning Glass Surfaces
Wipe off residues with a soft cloth or a paper towel.
Remove baked-on residues using a wooden or plastic scraper. Avoid using a metal scraper as it may
scratch the glass.
Surfaces may be cleaned using a soft cloth with mild soap and water. Alternately, a glass cleaning spray
with paper towels may be used.
Avoid scratching the surface of the glass.
DO NOT USE abrasive scouring powder or abrasive cleansers on the glass door, the lamp’s glass
shield and the control panel.
DO NOT USE metallic scouring pads.
DO NOT USE metal scrapers.
AVOID putting cold water or a cold damp cloth onto the hot glass as this may cause the glass to crack
and shatter
5.3.2 Guidelines for Cleaning Metal Surfaces
Wipe up spills and residues with a cloth or paper towel.
Remove baked-on residues using a wooden or plastic scraper. Avoid using a metal scraper on exterior
surfaces as it may scratch the metal finish of the rotisserie.
Surfaces may be cleaned using a soft cloth with mild soap and water. Alternately, a spray-on degreaser
may also be used but only on stainless steel surfaces following the handling procedure outlined on the
product label. Do not apply degreasers or other harsh chemicals to painted surfaces as this may
permanently affect the look and performance of the finish.
The look of stainless steel surfaces can be improved by using stainless steel polishing creams. Follow the
instructions on the packaging of the polishing product being used.
Avoid scratching or marring metal surfaces.
For stubborn build up on the interior stainless steel surfaces of the oven (including around the door’s
opening), bristle brushes or mild scouring pads can be used. Refer to the daily cleaning laminates for
details.
DO NOT USE abrasive scouring powder or abrasive cleansers.
DO NOT USE metallic scouring pads.
DO NOT USE metal scrapers on exterior surfaces.
DO NOT USE corrosive cleaning agents.

6. Troubleshooting
DISCONNECT POWER TO THE ROTISSERIE BEFORE ANY MAINTENANCE, SERVICE OR CLEANING
IS PERFORMED.
ROTISSERIES EQUIPPED WITH CASTERS ARE SECURED IN PLACE USING A RESTRAINING CABLE
LOCATED ON THE RIGHT REAR UNDERSIDE OF THE ROTISSERIE. THIS CABLE MUST BE
DISCONNECTED PRIOR TO REMOVING THE ROTISSERIE AND CAUTION MUST BE TAKEN TO
ENSURE IT IS CONNECTED ONCE THE ROTISSERIE HAS BEEN RETURNED TO ITS ORIGINAL
POSITION.
THE ROTISSERIE IS HOT WHEN OPERATING. EXERCISE CAUTION WHEN WORKING NEAR THE HOT
ROTISSERIE.
WEAR APPROPRIATE PROTECTIVE CLOTHING.
Rotisserie Does Not Operate
The rotisserie does not operate when the red main ON/OFF is pulled out (i.e. drive does not turn, and no lights in
cavity).
SOLUTION:
Verify that the door is fully closed. The magnetic door switch disables or enables the ignition system.
Check rotisserie electrical power: If the rotisserie's lights are off, check the circuit breaker on the back of
the unit as shown in Figure 3-1 and Figure 3-2. If the circuit breaker is ‘OFF’ (tripped), return to 'ON'.
If this circuit breaker is ‘ON’, ensure that the power cord is plugged into the wall and that there is power
coming from the socket. If power is available and the rotisserie still does not operate, contact your local
authorized service partner.
Safety Lockout
If the red main ON/OFF switch is pulled out, the drive drum will rotate and the igniter will attempt to light the burner.
If there is no flame after six minutes, the rotisserie will go into 'SAFETY LOCKOUT'. Push the red main ON/OFF
switch in to turn the rotisserie off.
Possible causes include: the gas supply is shut off, the flame sensor is not sensing flame or there is some
component failure.
SOLUTION:
If the rotisserie goes into ‘safety lockout’ again. Turn
the rotisserie off (push in main ON/OFF switch).
Verify that the gas supply to the rotisserie and the main
gas valve are both open. Try starting the unit again by
pulling the red main ON/OFF switch out.
If the rotisserie goes into ‘safety lockout’ again, turn the
rotisserie off.
When you are certain the rotisserie interior is cool to
the touch, gently lift the flame sensor and burner
covers out of the unit. See Figure 6-1.

8. Reinstall access panel.
9. Plug the power cord back into the wall receptacle.
10. Turn the rotisserie on (pull out main ON/OFF switch).
11. Verify that the replaced bulbs function correctly (it is
normal for the lights to take about 6 seconds to light after
the main switch is pulled ON). If not, repeat the first four
steps of this procedure and make sure the bulb was
correctly inserted in the socket. Reinstall the access
panel, turn the rotisserie ON and recheck. If problems
persist, contact your local authorized service partner.
