Maintenance of Units Containing Refrigerant
It is a legal requirement that all units containing F Gas refrigerants such as R407c,
R410a are serviced on a regular basis and that leak tests are carried out. This should
generally be carried out at least every six months and a service inspection sheet
issued to the customer upon completion. Log books should be kept on site by the
end user to prove that these works have been carried out. The responsibility of
compliance is shared by the end user and the appointed maintenance engineers.
Failure to comply with the F Gas regulations will result in invalidation of the warranty
on the refrigeration system within the unit.

Ensure that all power to the unit is switched off before carrying
out any servicing or maintenance task. Only trained and qualified service
personnel should repair or service air conditioning equipment containing a
refrigeration system. Follow all safety codes. Wear safety glasses and work
gloves. Extinguish any cigarettes or naked flames. If on inspection of the
refrigeration pressures a refrigerant leak is suspected, open all access panels to
ensure the gas has dissipated to atmosphere.
The access panel to the refrigeration service valves and switches is identified by
a red flammability label. Access to the compressor section is identified on the
unit drawing.
Check all electrical connections for signs of overheating or arcing. Check all
cables for signs of chafing or physical damage.
