Model 3911/3913 ____________________________________________________________________Installation and Set-Up
Section 2 - Installation and Set-Up
2.1 Location
Locate the unit on a firm, level surface in an area of mini-
mum ambient temperature fluctuation. A minimum of twelve
(12) inches of clearance is required at the top of the incubator
and a minimum of three (3) inches of clearance is required at
the rear of the incubator. This space is necessary to allow ade-
quate air flow around the refrigeration system.
2.2 Water (Humidity System) and Drain Connections
a. Connecting Water Inlet for Humidity System
Do not attempt to operate the humidity system
without filling it with water. The humidification
heater will overheat, and the overtemp safety ther-
mostat will shut the humidification system down.
The humidity reservoir will require approximately one
quart (0.946 liter) of water on the initial filling. For best opera-
tion of the incubator, sterilized distilled, demineralized or de-
ionized water should be used in the humidity reservoir. Water
purity should be in the resistance range of 50K Ohm/cm to 1M
Ohm/cm, or a conductivity range of 20.0 uS/cm to 1.0 uS/cm.
Refer to ASTM Standard D5391-93 or D4195-88 for measuring
water purity.
Distillation systems, as well as some types of reverse
osmosis water purity systems, can produce water in the quality
range specified. Tap water is not recommended as it may con-
tain chlorine, which can deteriorate the stainless steel. Tap
water may also have a high mineral content, which would pro-
duce a build-up of scale in the reservoir. High purity, ultra pure
or milli-q water is not recommended as it is an extremely
aggressive solvent and will deteriorate the stainless steel. High
purity water has a resistance of above 1M Ohm to 18M Ohm.
Even high purity water can contain bacteria and organic con-
taminants. Water should always be sterilized or treated with a
decontaminant, safe for use with stainless steel as well as safe
for the product, prior to being introduced into the humidity
reservoir.
Distilled or de-ionized water used in the humidity
reservoir must be within a water quality resistance
range of 50K Ohm/cm to 1M Ohm/cm to protect
and prolong the life of the stainless steel. Use of
water outside the specified range will decrease the
operating life of the unit and may void warranty.
Section 1 - Receiving
1.1 Preliminary Inspection
This incubator was thoroughly inspected and carefully
packed prior to shipment and all necessary precautions were
taken to ensure its safe arrival. Immediately upon receipt,
before the incubator is moved from the receiving area, carefully
examine the shipment for loss or damage. Unpack the incubator
and inspect its interior and exterior for any in-transit damage.
1.2 Visible Loss or Damage
If any loss or damage is discovered, note any discrepancies
on the delivery receipt. Failure to adequately describe such evi-
dence of loss or damage may result in the carrier refusing to
honor a damage claim. Immediately call the delivering carrier
and request that their representative perform an inspection. Do
not discard any of the packing material and under no circum-
stances move the shipment from the receiving area.
1.3 Responsibility for Shipping Damage
For products shipped F.O.B. Marietta, Ohio, the responsi-
bility of Thermo Electron ends when the merchandise is loaded
onto the carrier’s vehicle.
On F.O.B. Destination shipments, Thermo Electron and the
carrier’s responsibility ends when your Receiving Department
personnel sign a free and clear delivery receipt.
Whenever possible, Thermo Electron will assist in settling
claims for loss or in-transit damage.
