Delfield DBC-10 User Manual

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 flow back to the sump.

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.

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.

Be sure the location chosen has a floor strong enough to 

support the total weight of the cabinet and contents.  Reinforce 

the floor if necessary to provide for maximum loading.

For the most efficient 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.

It is recommended that the unit be installed no closer than 2” 

from any wall.  

A level cabinet looks better and will perform more efficiently 

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 

floor is very important.  If it becomes necessary to level the unit 

adjustable legs are available.

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.  

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.

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.

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).
