Installation

Location

Be sure the location chosen has a oor strong enough to
support the total weight of the cabinet and contents. Reinforce
the oor if necessary to provide for maximum loading.

For the most efcient operation, be sure to provide good air
circulation inside and out.

Inside cabinet: Do not pack the equipment so full that air cannot
circulate.

Outside cabinet: Be sure that the unit has access to ample air.
Avoid hot corners and locations near stoves and ovens.

Installation note: Evaporator drains are also located to the right
of the evaporator housing and run to a condensate evaporator
pan. No external drains are needed as this is all self contained.
Drain lines need to be kept free from obstruction to allow for
proper water removal.

Safe Chill™ Blast Chillers Service & Installation Manual

Stabilizing

All models are supplied on casters for your convenience, ease
of cleaning and mobility. It is very important, however, that the
cabinet be installed in a stable condition with the front wheels
locked while in use.

Should it become necessary to lay the unit on
its side or back for any reason, allow at least 24
hours before start-up so as to allow compressor
oil to ow back to the sump.

Electrical Connection

Refer to the amperage data on page 2, the serial tag, your
local code or the National Electrical Code to be sure the unit is
connected to the proper power source. A protected circuit of the
correct voltage and amperage must be run for connection of the
line cord, or permanent connection to the unit.

It is recommended that the unit be installed no closer than 2”
from any wall.

Leveling

A level cabinet looks better and will perform more efciently
when the doors line up with the door frames properly, the
cabinet will not be subject to undue strain, and the corners of
the shelves will not move around on the supports. Use a level to
make sure the unit is level from front to back and side to side.

The unit comes standard with non adjustable casters, a level
oor is very important. If it becomes necessary to level the unit
adjustable legs are available.

Operation Information

(SEE PAGE 4 FOR DIAGRAM OF CONTROL PANEL)

Operating Pressures

Normal operating pressures should be achieved during
the preservation mode, with approximately 75 of ambient
temperature. Freezer mode 15# suction and 220# discharge.
Chilling mode 55# suction and 220# discharge.
Blast Chilling (soft mode): This mode pulls the food down from
the starting temperature to food set point of 37˚F (FP1). Once
the temperature is obtained the unit sounds an alarm and either
switches to preservation mode automatically (after the alarm
times out) or manually. During pull down in soft mode, the blast
chiller maintains a box temperature of 23˚F (BT1). This mode is
primarily used for pulling down delicate foods.

The unit should be disconnected from the
power source whenever performing service,
maintenance functions or cleaning the
refrigerated area.

Be careful - the line cord is not run over by the
casters when moving the unit. This can damage
the cord.

Blast Chilling (timed mode): This mode operates in either a
soft or hard mode. The user can preset the amount of time the
chiller pulls down for up to 240 minutes (TC1). The unit will
pull down until the time is reached or the two probes hit 37˚F
(FP1). At this point the unit will sound an alarm and go into
preservation mode.

Freezer Mode: This mode pulls the food down from starting
point to 0˚F (FP3). In this mode the unit operates in a hard chill
mode until one of the two food probes reach 37˚F (FP1). At that
point the box temperature is pulled down to -25˚F (BT3) until the
food set point of 0˚F (FP3) is reached. At this point an alarm is
sounded and the unit can go into preservation mode.

Blast Chilling (hard mode): This mode operates the same way
as the soft mode except for the box temperature. During pull
down from start until one of the two food probes reaches 47˚F
(FP2) the box temperature is maintained at -5˚F (BT2), after
this point the box temperature is held at 23˚F (BT1) until the
food reaches 37˚F (FP1). This mode is for items that are harder
to pull down or if a faster chilling time is desired.

For customer service, call [phone], [phone], Fax [phone], www.deleld.com

Preservation Mode: After any of the above cycles reach their

set point, the unit will go into a preservation mode. This mode
will be held until the user terminates it. After chilling, the
food probes will maintain a temperature of 37˚F (FP1) using
a box temperature of 23˚F (BT1). After the freezing, the food
probes will maintain a temperature of 0˚F (FP3) using a box
temperature of -15˚F (BT3).

Defrost Mode: After chilling/freezing the unit will go into a

defrost mode for 15 minutes or until the coil reaches a
temperature of 70˚(DF1). During the freezer preservation mode
the defrost heater will operate for 15 minutes (DF2) or until the
coil reaches a temperature of 70˚F(DF1) every 6 hours (DF3).

Tandem Mode (DBC-10 only): In this mode, both the upper
and lower compartments will start at the same time running in
the same mode of operation (soft, hard, or freezer mode). Once
operating the compartments cycle independently. For example,
if the bottom compartment pulls down quicker than the top it will
shut down without affecting the tops operation.

Individual Mode (DBC-10 only): This mode allows operation of
the two compartments in different modes of operation starting
them at different times. For example, the top compartment can
be loaded to run in a timed soft chill cycle, and at any time the
bottom could be loaded in a freezer mode and started.

MAINTENANCE

The interior and exterior can be cleaned using soap and warm
water. If this isn’t sufcient, try ammonia and water or a
nonabrasive liquid cleaner. When cleaning the exterior, always
rub with the “grain” of the metal to avoid marring the nish. Do
not use an abrasive cleaner because it will scratch the metal.

In order to maintain proper refrigeration performance, the con­denser ns must be cleaned of dust, dirt and grease regularly.
The condenser coil is located behind the removable louvered
front and there are two coils located on the DBC-10. It is
recommended that these be cleaned at least once every three
months. If conditions are such that the condenser is totally
blocked in three months, the frequency of cleaning should
be increased. Clean the condenser with a vacuum cleaner
or stiff brush. If it’s extremely dirty, a commercially available
condenser cleaner may be required.

Door gaskets are dart style and can easily be replaced without
the use of any tools. Do not use sharp tools or knives to
scrape the bellows as this may tear the gasket and eliminate
its ability to seal. Door gaskets should be cleaned as required
to maintain their ability to seal properly. A soft bristle brush
and solution of soap and water will keep the gaskets clean. Do
not use full strength de-greasing agents on the gasket.

Pan slides are removable via the four thumb screws and are
made of stainless steel. They are dishwasher safe or can be
cleaned with soap and water.

Food Probes:

If necessary to check the probes, they are a 10,000 ohm
thermistor and it is important that they be kept away from
any high voltage wiring. There are four probes per section;
two food probes, one box probe and an evaporator probe.
Accessing the evaporator, expansion valve, and other evapora­tor components can be done by removing the pan slides and
pulling the evaporator housing away slowly as to not pull out
any wiring. Once access has been gained wire ties can be
cut and the housing can be removed. Food probes can be
cleaned with soap and water. For optimum use of the food
probes, do not allow the handle to rest in the food. When
removing a food probe from the food do not pull on the cable,
use the handle.

The control uses a lithium battery and may need to be
replaced approximately every ve years.
