BASIC TROUBLESHOOTING

WARNING LIGHTS

LOW WATER — The steamer is low on water or

the water sensors need to be cleaned.

HIGH WATER (CONNECTED MODELS ONLY)
Not Utilized on this model

OVER TEMP — The appliance has overheated.

It may have run out of water. Carefully open the

door, allowing steam to escape and then check

the water level in the bottom of the steamer If
it is nearly empty, Clean the water level sensor
probes (white buttons) located in the front left
corner and the wall immediately around them
being careful not to get burned (protective
gloves are strongly recommended). Refill the

steamer with 2 1/2 gallons of tap water and
restart

Food Is Under Cooked

 Try using perforated pans as they allow steam

to penetrate from all directions, maximizing

heat transfer and giving you the shortest
cooking times. Try distributing the product
more evenly within the appliance and or pans,
if possible.

 Make sure the water drain valve on the front

of the Evolution is tightly closed.

 The steamer may appear to be cooking normally

if the valve is slightly open but efciency may
be compromised.

 Check the door seal for food debris. Food

debris on the face of the door seal or under ap
may cause steamer to appear to be cooking
normally but efciency may be compromised.

 Nicks or cuts in the door seal may also cause

inefcient cooking.

If the steamer has plenty of water, allow it to cool.
This normally takes a few minutes. When the
Over Temp light goes out, restart the steamer.

Food Is Over Cooked

Check that the proper cook time is being used.

Food Is Under Cooked

 Make sure you are using adequate time

a. Extra time may be required if pans are
covered or if product is left in plastic bags
or similar packaging.

 Make sure the door is closed. When the

door opens the heat is turned off until it
is shut

 Make sure the steamer is in the Cook Mode;

Push the Display Temperature button to
ensure the steamer is at the boiling point
of water taking into account your elevation
above sea level. If it isn’t the appliance
maybe in the Hold Mode. Variations
in temperature can also be caused by
frozen product just being put in or with the

connected model a fresh measure of tap

water was activated. These will shortly

come up to temperature as long as the door

is closed.

Steamer won’t come on

 Verify that the breaker in the power pack is in

the active position

 Verify that the power pack is plugged in

Steamer doesn’t heat

 If the operator’s display doesn’t light up, See

section“ Steamer won’t come on”.

 Verify the steamer door is closed, as the

heat won’t turn on if the door is open.

Steam comes out the door

 Verify that the door is completely closed and

latched.

 If the appliance was just lled with water, wait

a minute to see if it stops. After the steamer is
relled with water it is normal for some steam
to come out the door for a brief amount of
time, usually less than one minute.

Steamer Temperature is low

 Make sure door is closed
 Verify that the low water light isn’t on
 Verify the appliance is in the Cook Mode not

sensor, to the Control/Keypad Board to provide a digital temperature display.

• Control Panel will show PRE (Preheat) on initial start-up until the steam chamber reaches
195°F, then COO (Cook) will be displayed between 195°F and 212°F.

• The operating default mode on initial PWR ON is COOK mode; which automatically causes
the steamer to go to the normal operating boiling point, which is 212°F at sea level.

• In COOK mode, the 24VAC output from the Control/Keypad Board is continuously on, so

that the unit’s temperature is controlled by the Chamber Pressure Switch, which opens at 1/2

PSI (13.9 “ water column) or higher.

• In HOLD mode (HLD), the steamer’s regulated temperature will change to the HOLD

temperature’s preset value. The Control/Keypad Board will regulate temperature via the

RTD input, based on the current HOLD mode preset value. (This value can be changed
using the program function on the Control/Keyboard Control.)

LIMITED WARRANTY

One Year– Parts and Labor

U.S. & Canada Only

AccuTemp Products, Inc. (AccuTemp) warrants that your AccuTemp equipment will be free of
defects in material and workmanship under normal use for a period of twelve (12) months from
installation or fteen (15) months from date of shipment from AccuTemp, whichever date rst
occurs (the Warranty Period). Registration of AccuTemp equipment is required at the time of
installation. Damage to AccuTemp equipment that occurs during shipment must be reported to
the carrier, and is not covered under this warranty. The reporting of any damage during shipment is
the sole responsibility of the commercial purchaser/user of such AccuTemp equipment.

AccuTemp provides an active service department, which should be contacted and advised of
service issues, regardless of the warranty period. During the warranty period, AccuTemp must be
contacted for warranty repairs and agrees to repair or replace, at its option, F.O.B. factory,
any part which proves to be defective due to defects in material or workmanship, provided
the equipment has not been altered in any way and has been properly installed, maintained, and
operated in accordance with the instructions in the AccuTemp Owners Manual. During the warranty
period, AccuTemp also agrees to pay for any factory authorized equipment service agency (within
the continental Applianceed States and Canada) for reasonable labor required to repair or replace,
at our option, F.O.B. factory, any part which proves to be defective due to defects
in materials or workmanship, provided the service agency has received advance approval from
AccuTemp factory service to perform the repair or replacement. This warranty includes travel time not
to exceed two hours and mileage not to exceed 50 miles (100 miles round trip), but does not include
post start-up assistance or training, tightening of loose ttings or external electrical connections, minor
adjustments, maintenance, or cleaning. AccuTemp will not reimburse the expense of labor required
to replace parts after the expiration of the warranty period.

Proper installation is the responsibility of the dealer, owner-user, or installing contractor and is
not covered by this warranty. Improper installation can affect your warranty. Installation is the
responsibility of the Dealer, Owner/User or the Installation Contractor. See the Installation
section of the Owners Manual. While AccuTemp products are built to comply with applicable
standards for manufacturers, including Underwriters Laboratories (UL) and National Sanitation
Foundation (NSF), it is the responsibility of the owner and the installer to comply with any
applicable local codes that may exist.

AccuTemp makes no other warranties or guarantees, whether expressed or implied, including

any warranties of performance, merchantability, or tness for any particular purpose. AccuTemp
liability on any claim of any kind, including negligence, with respect to the goods and services
covered hereunder, shall in no case exceed the price of the goods and services, or parts
thereof, which gives rise to the claim. In no event shall AccuTemp be liable for special,
incidental, or consequential damages, or damages in the nature of penalties.

This constitutes the entire warranty, which supersedes and excludes all other
warranties, whether written, oral, or implied.
