INSTALLATION
Local city, county, or other ordinances may govern the use of this equipment. If you have any questions about local
requirements, please contact the appropriate local agency. Installation may be performed by the end user.
Under normal circumstances these units are intended for use indoors, at room temperatures between 15

and 35

C, at no
greater than 80% relative Humidity (at 25

C) and with a supply voltage that does not vary by more than 10%. Installation
category is CAT-II Pollution Degree 2. Customer service should be contacted for operating conditions outside of these
limits.
3.1 Power Source: The unit power requirements are listed on the data plate. PLUG THE UNIT INTO A
PROPERLY GROUNDED AND RATED RECEPTACLE OF THE CORRECT STYLE. THE VOLTAGE OF THE
RECEPTACLE SHOULD NOT VARY MORE THAN 10% FROM THE DATA PLATE RATING. A separate
circuit is recommended for this unit to prevent loss of product due to overloading or circuit failures caused by
other equipment. Position the unit to allow user access to the power cord.
3.2 Location: When selecting a site for the unit, consider conditions which may affect performance, such as heat
from radiators, ovens, autoclaves, etc. Avoid direct sun, fast-moving air currents, heating/cooling ducts, and
high-traffic areas. To ensure air circulation, allow a minimum of 30 cm between the unit and any walls or
partitions which might obstruct free air flow.
3.3 Lifting / Handling: These units are heavy and care should be taken to use appropriate lifting devices that are
sufficiently rated for these loads. Units should only be lifted from their bottom surfaces. Doors, handles and
knobs are not adequate for lifting or stabilization. The unit should be completely restrained from tipping during
lifting or transport. All moving parts such as shelves and trays should be removed and doors need to be
positively locked in the closed position during transfer to prevent shifting and damage.
3.4 Leveling: The unit must sit level and solidly. Models SVAC1 (1425) and SVAC1-2 (1425-2) have four (4) rubber
feet that are already attached to the unit and are not adjustable. Leveling feet are supplied with models SVAC2
(1445) / SVAC2-2 (144-25) and SVAC4 (1465) / SVAC4-2 (1465-2) and must be installed in the four holes at the
base of the unit. With the unit standing upright, turn the leveling feet counterclockwise to raise the level of that
corner. Adjust each foot until the unit stands solid and level. If the unit must be moved, turn the leveling feet in all
the way to prevent damage while moving.
3.5 Cleaning: The unit chamber should be cleaned and disinfected prior to use. The operating conditions and
appropriate protocol will determine the correct procedure for decontamination. A typical decontamination
procedure that is adequate for many situations has been described below. As well, certain steps are listed
that will help reduce the likelihood of contamination and the necessity of decontamination. Whatever
process is appropriate, it needs to be done on a regularly scheduled basis. Depending on usage and
protocol, this may be monthly, quarterly or otherwise. Regardless of the decontamination procedure used,
certain precautions will need to be taken:
A. Always disconnect the unit from the electrical service when cleaning.
Assure all volatile or flammable cleaners are evaporated and dry before reconnecting the unit to the
power supply.
B. Special care should be taken when cleaning around sensing heads to prevent damage.
C. Do not use chlorine-based bleaches or abrasive cleaners this will modify the stainless steel interior
finish. DO NOT USE hard tools such as metal wire brushes or steel wool. Use non-abrasive
cleaners and soft tools such as plastic brushes.
D. In the event hazardous material is spilled onto or into the equipment, appropriate decontamination
must be carried out. If there is any doubt about the compatibility of decontamination or cleaning
agents with parts of the equipment or with material contained, please contact the manufacturer or
his agent. No decontamination or cleaning agents should be used which could cause a hazard as a
result of a reaction with parts of the equipment or with the material contained in it.
3.6 Shelves: See Figure below. Place items on shelves. DO NOT place items directly on the floor of the chamber.
