Taylor-Wharton 24K w/ AutoTend - Manual (Page 3)

Electrical
Electrical Shock Can Kill – the liquid level controllers used with these refrigerators
operate from 24VAC. However, the external transformer does have a 110/220VAC
primary. Do not attempt any service on these units without disconnecting the electri-
cal power cord.
Freight Damage Precautions
Any Freight damage claims are your responsibility. Cryostorage systems are
delivered to your carrier from Taylor-Wharton’s dock in new condition. When you
receive our product you may expect it to be in that same condition. For your own
protection, take time to visually inspect each shipment in the presence of the carrier’s
agent before you accept delivery. If any damage is observed, make an appropriate
notation on the freight bill. Then, ask the driver to sign the notation before you receive
the equipment. You should decline to accept containers that show damage which
may affect serviceability.
Taylor-Wharton CryoStorage Systems are designed for applications where extremely
low temperature storage of biological products is required. They are also appropriate
for industrial or other applications where liquid nitrogen temperatures and high
capacity are needed.
The 10K, 24K and 38K refrigerators covered by this publication are designed for, but
not limited to, the laboratory environment. The 10K and 24K feature square, modular
cabinets that facilitate grouping several units together in a cryostorage area. The 38K
features a cylindrical stainless steel cryochamber. All of the models will accommo-
date inventory control systems or provide unobstructed storage area for larger
product. All models are supplied with casters to enable limited mobility for cleaning
purposes.
These standard models are equipped with the KRYOS electronic liquid level control-
ler that will monitor and control the supply of liquid nitrogen to the unit. The controller
features vacuum fluorescent display. The addition of a liquid nitrogen supply and
inventory control racks for systematic retrieval of stored product completes the total
cryostorage system.
Maximum Refrigerator Contents
Your cryostorage system has a maximum weight capacity which is stated in the
specifications. This capacity exceeds the maximum amount of liquid nitrogen the
refrigerator is capable of holding. Generally, as product is added to liquid phase
storage, the stored product and inventory control system are heavier than the liquid
nitrogen they displace. In vapor-phase storage applications, where the liquid refriger-
ant is found only in the bottom portion of the refrigerator, the weight of contents is
determined more by the weight of the stored product.
Note:
Units are supplied with Taylor-
Wharton approved controllers.
If other liquid level controllers
are used, please contact
Taylor-Wharton before putting
the refrigerator into service.
