11.Probe positioning (Fig. 9)

S1 Air delivery control probe
S2 End defrost thermostat control probe
S3 Air intake control probe
- Temperature probe: NTC IP67 L=4000 cod.04510153.
- Probes S1 - S3 must be fixed in place using terminals and should not be insulated.
- Probe S2 must be fixed in place with contact between the 3rd and 4th tube (never in correspondence
with the fan) using the stainless steel bulb block spring, cod.02230021.

12.Control and adjustment of temperature (Fig. 4)

The refrigeration temperature is controlled using the thermometer (Rif. 5) or with the electronic control
device (OPTIONAL) located on the lower part of the unit (Rif. 5). Normally the controller is set in the
factory during testing, but it is possible to alter programming. To do so, please refer to the instructions
given by the control device manufacturer. If using electronic control devices to adjust the frame heating
wires, these must be operated at full power.
N.B.All these operations should be performed by specialized technical personnel.

13.Loading the unit (Fig. 4 - Fig. 4)

When loading the unit, some important rules must be observed:
- place the merchandise so that it never exceeds the maximum load line (Rif. 6). Exceeding this limit
disturbs proper air circulation, causing an increase in the temperature of the merchandise and the
formation of ice on the evaporator;
- placing the merchandise to avoid empty areas, guarantees that the unit will perform at its best.
- it is recommended that merchandise that has stayed longer in the unit be consumed before that which
was placed more recently (rotation of foodstuffs)
- The maximum allowable load for the tank is 300 kg/m
13_1.Loading the unit for ice cream and frozen food
- decrease as much as possible the time that frozen food is subject to room temperature and humidity
in order to avoid the formation of frost on boxes, which after insertion into the unit, may stick to each
other and to the grills on the bottom.
- limit the time the doors are open to 2 - 3 minutes
- leave 4-5 cm. of space between the merchandise and the closures to allow normal circulation
of the refrigerated air.
N.B.Entry of warm air into the unit with closures is inevitable. In the case of high humidity,
a thin layer of frost will form. This will disappear if the doors are left closed for 2 hours.
N.B.The refrigeration unit is designed to maintain the temperature of the displayed product and
not to decrease it.
Food products should be inserted only if they are already cooled to their respective conserva-
tion temperatures. DO NOT insert products that have been heated.
ATTENTION!: It is prohibited to use the sliding closures as a shelf for merchandise while loa-
ding the unit. These closures are not designed to support any type of load (Rif. 7).

14.Defrosting and water discharge (Fig. 8)

The Toronto line of refrigerator units can be provided with one of 2 automatic defrost systems (3 defro-
sts per day, for 30 mn.):
Electric defrost;
This is performed by no. 3 shielded electrical resistances inserted in each evaporator (230V).
Hot gas defrost;
This is performed by sending hot gas (produced by compressing the coolant) to the evaporator, which
acts as a condenser as it heats, melting all the ice that has formed.
During the defrost phase, the temperature of the displayed products will increase, but in any case will
not exceed the limits imposed by the Law. Once the defrost phase is completed, the system will qui-
ckly reach operating temperature (- 18°C - 25°C).
Water discharge;
To discharge the water from defrosting, proceed as follows:
