11 - Conditions to be verify for a proper installation
-
Ensure an adequate free space (approx. 30% of the inner room volume) to allow a proper intake and exhaust
air circulation.
!
Particular conditions of installation or operation such as low or beamed rooms, overstorage,
obstructed intake and exhaust air circulation and improper ice build-up due to excessive entry of
humidity in room may negatively affect the stated performance and may cause defects.
Standard models may not be suitable for blast freezer and chill room application.
-
The models are equipped with axial fan motors, therefore not suitable for duct ventilation systems and cannot
sustain extra static air pressure drops.
-
Verify that the operating conditions (temperatures and pressures) are in accordance to those of project.
-
In the case of more than one model installed at close range it is advisable to avoid alternate defrostings.
-
Fit the appropriate siphons on the condensate drain connections and assess their efficiency in all working
temperatures.
-
Avoid installation of the units next to the cold-room doors.
-
If are used, place the end of defrost temperature feeler in the coldest areas of the coil, i.e. the areas that tend
to freeze more (at the end of the cycle the unit should be completely ice-free).
The position of this device cannot be defined in advance, because it varies in accordance to the type cold
room and type of installation.
-
The protective film is to be removed from model upon completion of installation.
11.1 - General Maintenance
-
It is necessary to arrange periodical cleaning of unit in order to avoid deposits of toxic substances. Use of
mild detergent is recommended; avoid use of solvents, aggressive, abrasive or ammonia-based agents.
-
When replacing electric heaters take particular care during installation in order to avoid damage to the
vulcanization; correctly reset wiring and existing fastening systems to avoid possible movement during
operation.
The above-mentioned operations are to be carried out by qualified personnel only.
Only use ammonia to pressurize the unit. Do not use other fluids, such as water.
The maximum pressure at which the unit can operate is indicated on the plate: it is forbidden to
exceed the maximum pressure indicated on the plate.
The contamination of the coolant can cause damage to the plant and injure the user. In particular, be careful not to
put the liquid in contact with the following contaminants:
-
Moisture
-
Atmospheric air
-
Welding residues
