Reliable operation and optimised machine performance are only guaranteed by the use of original spare parts. The man-
ufacturer reserves the right to make any changes considered appropriate to the machine described without prior notice.
1.2 Information about precautions, specic warnings and symbols
Where necessary, this manual includes information alongside machine operating and maintenance instruc-
tions or procedures.
There are also indications marked with the “Caution/Danger” symbols, shown in bold type and upper case
letters to make them clearly visible.
The “GENERIC CAUTION/DANGER” symbol is used to indicate that failure to comply with the safety
regulations described in this manual could result in “Damage to the machine and/or objects and injury to
machine users”.
The “BURN HAZARD” symbol is used to indicate that failure to comply with the safety regulations described

1.3 Testing, guarantee and liability
Testing
Before being sent to the dealer/buyer, the machine must successfully pass testing by the manufacturer.
Guarantee
DIAMOND guarantees the machines put on the market for 12 months from the date of delivery. During the guarantee period
the manufacturer undertakes to substitute, free of charge ex works, any parts which may develop a fault due to obvious
manufacturing defects or poor quality materials. Parts substituted remain the property of DIAMOND and must be returned
to its premises, free of all charges. If the substitution of defective machine parts requires work by technical personnel,
labour costs and any travel and accommodation expenses will be charged to the buyer. Top ups of refrigerant gas are not
covered by the guarantee. The guarantee shall be void if the machine is used in a way that does not conform to what is
indicated in the manufacturer’s “operating and maintenance manual”. The guarantee shall be void if the operator, delib-
permission from the manufacturer. The guarantee shall also be void if the electric and water connections used to supply
the machine, (which are the buyer’s responsibility), are made in a way that does not conform to what is indicated in the
machine “operating and maintenance manual”. Interruption of the payment agreed in the sales proposal and accepted by
the manufacturer will result in suspension of the guarantee.
Liability
DIAMOND declines any responsibility and obligation for any incident involving persons and objects resulting from use of the
machine in any way that does not conform to what is indicated in the “operating and maintenance manual” and/or due to
manufacturing defects of the components/materials present in the machine. It shall also be considered expressly excluded
from any other claim for reimbursement for lost earnings attributable to any failure to operate.
1.4 Purpose of the manual
This manual was drawn up with the aim of providing all machine operators, in the most complete and clearest way possible,
with all information necessary for machine installation, use and routine maintenance, from the time the machine reaches
the market until the moment it is decommissioned and/or scrapped.
It also lists all procedures useful for dealing with emergencies which may arise during use of the machine as described by
the manufacturer and those which are reasonably foreseeable.
Important note: the manual does not substitute technical training for personnel who will use the ma-
chine. It should be considered a guide to the use of machine functions.
1.4.1 Structure of the manual
interpretation and implementation of the activities required for machine operation and maintenance.
This manual includes all instructions with which the operator must be familiar and information which the operator may
consult in order to achieve the aims of the manual.

1.7 Intended uses
The PCT T range of machines are designed for:
1. Mixing and heating/cooking ingredients or pre-packaged foods placed inside the machine cylinder.
2. Chilling, churning and freezing the ingredients processed for making gelato, creams, jams, sauces, granita and sorbet.
This processing takes place in a vertical cylinder using a mixer and retaining paddle supplied with the machine.
“PCT T” models can process products which require hot/cold thermal treatment. Pasteurising and churning are carried
out in a single cylinder, avoiding any transfer or handling and guaranteeing maximum hygiene for the processed product.
THE MACHINE CANNOT BE USED FOR OTHER PURPOSES WITHOUT TELME S.P.A.'S AUTHORISA-
TION. TELME S.P.A. WILL NOT BE RESPONSIBLE FOR DIRECT OR INDIRECT DAMAGES DUE TO
IMPROPER USE OF THE MACHINE.
1.7.1 Reasonably foreseeable improper use
1. Do not insert in the cylinder a quantity of product that is less than that recommended, as during cooling it could lead to
ice forming on the cylinder wall. That would make the machine noisy, cause wear and damage to the mixer scrapers.
The suitable quantity of product which can be processed is indicated in sec. 2.4 “Machine technical data" of
this manual.
2. Do not insert in the cylinder a quantity of product that is more than that recommended, as it could prevent correct
machine operation, and the product can leak out of the cylinder. That would stress the mixer’s motor-driven shaft. The
suitable quantity of product which can be processed is indicated in sec. 2.4 “Machine technical data" of this
manual.
A. For hot processing:
• During “heating” of the ingredients placed in the cylinder, do not lift the cover on the top of it unless you are wearing
suitable gloves which protect against heat.
• During extraction of a “hot” product ("liquid" products, creams, jams, etc.) do not completely lift the extraction door lever,
extraction, do not exceed 200 rpm for doughy products, 80 rpm for creamy products and do not activate extraction
for liquid products. Do not accidentally open the extraction door lever with improper movements and/or positions. Use
heat-resistant gloves and/or suitable protective clothing.
• When cooking and/or heating with “liquid” products, maintain the mixer speed of rotation indicated in the programs,
personal protective equipment for high temperatures (heat-resistant gloves and protective clothing).
• When cooking and/or heating with “liquid” products, be extremely careful not to “accidentally” start other programs
cylinder while the temperature of the remaining product and/or of the surface of the cylinder is such that it risks causing
scalding and/or burns by contact with or proximity to parts of the machine or materials at a very high temperature. Use
heat-resistant gloves and/or suitable protective clothing.
B. For cold processing:
while the temperature of the remaining product and/or of the surface of the cylinder is such that it risks causing injuries
by contact with or proximity to parts of the machine or materials at a very low temperature. Use heat/cold-resistant
gloves and/or suitable protective clothing.
