7. OPERATION AND MAINTENANCE
7.1 OPERATIONAL LIMITS
• This unit is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible
for their safety;
• Children should be supervised to ensure that they do not play with the unit;
• For installations without a thermostat or room temperature limiting device, it is prohibited to
use the fancoil in small rooms occupied by people unable to leave the room by themselves,
unless they are not under constant surveillance.
Since your YEFB unit is equipped with a water-fed heat exchanger, be sure that ambient
temperature does not fall below 0 °C, which could cause the formation of ice in the exchanger
pipes with consequent risks of frost damage.
If ambient temperature may fall below 0 °C, drain the coil when the unit is not being used.
7.2 ORDINARY START-UP AND MAINTENANCE
After connecting the unit to the pipe system and after filling the coil, bleed any residual air
in the system by opening the air bleed valves located near at the top of the water piping
system, as specified in Par. 6.4.1.
Before starting the system please check:
•
the proper opening of the valves,
• the absence of water leaks from the pipes,
• the correct drainage of the condensate water, by spilling some water into the pan,
• the correct running of the regulation and control devices.
During operation (as well as during installation), make sure that the air intake and the
delivery outlets are not blocked in any way.
The user has to be sure that the YEFB air-handling unit operates by respecting
the use limits and that each installation and/or maintenance operation is
executed by qualified personnel only.
Before servicing the filter or the electrical system and, in any case, before removing
the protection structures, make sure that the unit has been disconnected from
the power mains. Protection structures have to be reassembled before giving
voltage to the unit.
