Calibration
The power cord of this instrument is equipped with a three-prong
(grounding) plug which mates with a standard three-prong (grounding)
wall receptacle to minimize the possibility of electric shock hazard from
this apparatus. The customer should have the wall receptacle and circuit
checked by a qualified electrician to make sure the receptacle is properly
grounded.
Where a two-prong wall receptacle is encountered, it is the personal
responsibility and obligation of the user to have it replaced with a properly
grounded three-prong wall receptacle.
Warning
Do not, under any circumstances, cut or remove third (ground)
prong from the power cord. Do not use a two-prong adapter plug.
s
Determine the total amount of current presently being used by other
apparatus connected to the circuit that will be used for this unit.
It is critical that the added current demand and other equipment on the
circuit not exceed the rating of the fuse or circuit breaker in use.
Caution
Be sure the power supply is the same voltage as specified on the
nameplate.
s
When loading the growth chamber, a space of 1/2" must be allowed
between adjacent items in the chamber. This will allow maximum air
circulation, necessary for proper temperature uniformity. The uniformity
will be adversely affected if air circulation is obstructed.
Liquid containers should never be placed in the growth chamber without
covers. The evaporation of moisture within the chamber will only add frost
and hasten the need for defrosting. This chamber is not self-defrosting.
Excessive frost buildup on the evaporator coil located on the lower back
wall will also affect temperature uniformity.
1. Do not place any explosive,combustible, or flammable materials in the
chamber.
2. Do not place sealed containers in the chamber. Sealed containers, filled
with material, do not provide room for expansion and can develop
dangerous vapor pressure as the temperature increases.
3. Avoid spillage of liquids within the chamber.
4. Do not evaporate noxious fumes.
Caution
Do not store containers filled with acidic or caustic solutions, as
vapors from these materials will attack the evaporator and void the
