Installation SORVALL ® Centrifuges
2-2
A qualified technician may change the power cord to meet local
electrical code requirements; the green and yellow wire is the ground
and must be connected to the centrifuge frame.
A dedicated circuit is required. The ON/OFF main power switch is
a 30-Amp circuit breaker; however, for emergency disconnect pur-
poses, we recommend a separate means of power interruption in a
remote location.
Environment Requirements
Ambient air temperature at the centrifuge air inlets must be be-
tween 15
°
C to 38
°
C (59
°
F to 100
°
F), with relative humidity
≤
90%,
for the centrifuge to operate. If the ambient air temperature is above
25
°
C, the centrifuge may not maintain low temperatures at high
speeds, therefore, avoid areas near heat sources (for example, heat-
ing pipes and radiators). Also, avoid close grouping of centrifuges
or other heat-producing laboratory equipment.
The centrifuge is intended for use in 1) a Pollution Degree 2 Envi-
ronment, 2) an installation category II supply circuit, 3) at a maximum
altitude of 2000 meters, and 4) for indoor use only.
Location Requirements
Locate the RC-5C PLUS centrifuge on a level floor. In addition to
considering ambient temperature (see environment requirements,
above), allowing adequate space for air circulation is important for
the centrifuge to function properly. To ensure free air circulation,
the centrifuge must be positioned so that no air vents are blocked,
in a location that allows an additional 10 cm (4 inches) clearance
from all sides of the centrifuge.
For safety, personnel should know that centrifuges routinely deal
with high energy levels and could move suddenly in the unlikely
event of a rotor failure. Laboratory management procedures should
require that no person or any hazardous materials are within a
“clearance envelope” boundary of 300 mm (12 inches) from the
centrifuge while it is operating. During centrifuge operation, per-
sonnel should be instructed not to lean on or move the centrifuge,
not to stay within the clearance envelope longer than necessary for
operational reasons, and not to deposit potentially hazardous ma-
terials within the clearance envelope.
C A U T I O N
Leave adequate space for
air flow around the centrifuge and
make sure no vents are blocked.
Blocking the air flow entering and/or
exiting the centrifuge can result in
reduced performance, overheating
and possible centrifuge damage.
