13. Verify that the operating conditions (humidity, temperature
and pressure) are in accordance to those of model.
14. Ensure that at the end of each electric or hot gas defrost
cycle the finned pack of the coil is clean. Frost build-up
tends to transform into ice, which is difficult to remove and
may cause the breakage of the heat exchanger.
15. For the models with electric defrost, in accordance to the
type of cold room, appropriately define the timing and the
number of heater ignitions (defrost cycles). Should tempe-
rature probes be used they must not interrupt the correct
defrost cycle, but be used only as a safety device in case
of possible overheating. If end of defrost cycle temperatu-
re probes are used they must be placed in the coolest
areas of the heat exchanger (areas in which frost/ice build-
up is possible) and far from the heaters.
16. Access to the installed model, for service and/or mainte-
nance, must be carried out by qualified and experienced
personnel in compliance to the regulations in force.
17. Install siphons on the drain connections and check effi-
cacy in all operation temperatures.
General maintenance & control
1. The unit consists of a finned pack heat exchanger with
copper tube and aluminium fins, aluminium-magnesium
casing, fan motors equipped with internal thermo-con-
tacts. For models with electrical defrost, the shielded,
stainless-steel, vulcanized heater rods are placed and
secured in the heat exchangers and in the drip trays.
2. Before performing any maintenance make sure that elec-
tric feed is disconnected from the main power source: as
the electrical parts may be connected to an automatic
control system. All maintenance operations must be car-
ried out by qualified and experienced personnel.
3. Periodically inspect fastenings, electrical connections and
connections to refrigerant installation.
4. It is necessary to periodically arrange the cleaning of the
unit's casing with a 50%-50% solution of diluted ethyl alco-
hol and water or a mild detergent. Do not use solvents,
aggressive, abrasive or ammonia-based solutions.
5. It is also necessary to periodically arrange cleaning of the
finned pack - use an aqueous solution with 50% diluted
ethyl alcohol or eventually with some peroxide should
greater cleanliness/sanitation be required. Do not use
solutions containing ammonia or chlorine. Use mild deter-

(A) During the installation phase observe the minimun dis-
tance as to allow proper functioning of motor.
- Ø 350 mm the minimum distance is 450 mm.
- Ø 400 mm the minimum distance is 600 mm.
- Ø 450 mm the minimum distance is 700 mm.
- Ø 500 mm the minimum distance is 800 mm.
gent, soapy water, on greasy residues then rinse tho-
roughly.
6. Check the efficacy of defrost. For models with electric
defrost, periodically verify the working condition of all hea-
ters. The manufacturer is in no way liable for defects and
damage caused by undetected malfunctions (e.g. damage
due to ice build-up).
7. See to the replacement of malfunctioning electrical hea-
ters. It is important to pay particular attention during instal-
lation as to avoid damaging the heaters; carefully recon-
nect the heaters (see attached schemes) and fasten them
in order to prevent dislodgment during operation.
8. The testing and maintenance periods depend on the type
of cold room, therefore these must be determined by qua-
lified and experienced personnel.
9. For all other operations, not illustrated in this manual, con-
tact the manufacturer.
