CHILLED WATER TEMPERATURE
The minimum temperature of the water leaving the evaporator is 5°C: lower temperatures are possible,
but for such applications the Manufacturer should be consulted at the time the order is placed.
The maximum temperature of the water entering the evaporator is 20°C. To allow higher temperatures
specific equipment solutions must be adapted (split circuits, three-way valves, bypasses, storage
reservoirs): applications outside the specified limits may be authorised by Galletti S.p.A. subject to
verification and subsequent authorisation in writing.
8.3 OUTDOOR
AIR
TEMPERATURE
The units are designed and built to work with outdoor air temperatures ranging from -10 (with
condensation control) to 45 °C. Applications outside the specified limits may be authorised by Galletti
S.p.A. subject to verification and subsequent authorisation in writing. On request, the units may be
equipped with an electric heating element for heating the evaporator in cases where the unit is exposed
to severe temperatures during wintertime shutdown periods.
The heating element is activated whenever the temperature of the water leaving the evaporator falls
below the temperature set on the antifreeze probe.
8.4
OPERATION WITH WATER AT LOW TEMPERATURES
The standard units are not designed to work with chilled water temperatures below 5°C at
the evaporator outlet. In order to work below this limit, the unit requires specific technical
adjustments: in such cases contact the Manufacturer.
9 SETTING OPERATING PARAMETERS
9.1 GENERALITIES
All the control devices are set and tested in the factory before the unit is dispatched. However, after the
unit has been in service for a reasonable period of time you can perform a check on the operating and
safety devices. The settings are shown in Tables I and II.
The control devices may be serviced SOLELY BY QUALIFIED TECHNICIANS:
incorrect settings may cause serious damage to the unit and injury to persons.
Many of the operating parameters and system settings are configured by means of the microprocessor
control and are protected by passwords.
