PRE-INSTALLATION REQUIREMENTS
6 Planmeca Sovereign
Installation manual
Storage conditions
Accepted limits for unit storage are the following:
Temperatures: -5 °C to +60 °C (23 °F to 140 °F)
Relative humidity: 5% RH to 95% RH “Absence of condensation”
Air pressure: 700 hPa to 1060 hPa (10 psi to 15 psi)
NOTE If the unit has been stored at temperatures below +10 °C (50 °F) for more than few hours,
time must be allowed for the unit to reach the room temperature in its own package, be-
fore connecting the dental unit to mains voltage.
Unit operating conditions
Accepted limits for unit operating are the following:
Temperatures: +15 °C to +35 °C (59 °F to 95 °F)
Relative humidity: 5% RH to 95% RH “Absence of condensation”
Air pressure: 800 hPa to 1060 hPa (12 psi to 15 psi)
Altitude: < 2000 m (less than 1.25 miles)
3.4 Plumbing requirements
Air supply
The air pressure used must be between 550-900 kPa (5.5 – 9 bar) (80 - 130 psi) with a flow of
at least 55 l/min. A compressor with an air dryer must be used to ensure that the air is clean,
dry and oil free.
Both air and water supply lines must be supplied with manual valves which close the air
supply according to the dental unit.
Water supply
The water pressure used must be between 300-900 kPa (3 - 9 bar) (45 - 130 psi) with a flow
of at least 3 l/min. The water must be drinking quality and free of all particles larger than 5µm
that could block the small tubes in the dental unit.
If the water supply contains particles larger than 5µm an accessible filter (5 micron)
must be fitted to the water inlet pipe.
If the water has hardness greater than 8 °dH (1 °dH = 20 mg calcium/3 l water) a water
conditioner must be fitted to the water inlet pipe. Hard water can very quickly ruin a dental
unit.
NOTE The water supply line must be equipped with back flow prevention valve according to
local requirements. Refer to the installation pattern.
Suction
The produced static vacuum prior to the suction calibrating valve must be at least 150 mbar.
The vacuum pump must be able to produce a flow of at least 550 l/min. when measured at the
installation position.
The suction line must be fitted with a suction calibrating valve, which limits the
maximum vacuum to 140 mbar.
Avoid using sharp bends or joints in the suction line. Seal all joints to avoid air leakage. Care
should be taken to avoid condensation, particularly when the pipe is exposed to different
ambient temperatures. Moisture traps must be used if necessary.
