Important installer and user information:

A redundant temperature sensing device has been included in this ULT freezer. This
device is a type “T” thermocouple. For convenient access, the thermocouple (Figure 1-

3) terminates in an interconnect jack (Figure 1-5) behind the base front cover. (May be
located differently in chests. See Section 1.) It is strongly recommended that this ther­mocouple be attached to a redundant 24 hour 7 day monitoring system with alarm
capabilities. Connecting the sensor to a monitoring and alarm system separate from the
freezer provides the utmost in product safety, should the integral system fail.

Install Freezer

To remove the freezer from the pallet, use a 7/16" wrench to remove all
the bolts securing the shipping bracket to the pallet.

Note If tipped more than 45°, allow the unit to set upright for 24 hours
before start up.

Remove the shipping bracket. Remove the ramp boards from the pallet
and place the slotted end over the ramp brackets on the pallet. The
support blocks on the ramps will be facing down. Before moving the
freezer, make sure the casters are unlocked and moving freely. Align the
caster with the ramp boards. Use adequate personnel to roll the freezer off
the pallet.

The freezer can be easily pushed to the desired approved location, as
described previously. When the freezer is in position, set the front caster
brakes.

Note Do not move the freezer with the product load inside.

Installation and Start-up

Choose Location

Install Wall Bumpers

Locate the freezer on a firm, level surface in an area with an ambient
temperature between 18°C and 32°C. Provide ample room to reach the
mains disconnect switch (power switch) located on the rear of the freezer.

Note For proper ventilation and airflow, a minimum clearance of 5” at the
rear and front and a clearance of 8” on the side of the freezer is required.
Allow adequate space for lid opening. If ambient increases above 36°C,
clearance at the rear of the cabinet must be increased to 8”.

s

The parts bag, located inside the cabinet, contains the following parts.

Quantity Stock # Description Purpose

2 510016 1/4-20 x 5-1/2” Bolt Wall Bumper

2 380520 Neoprene Cap Cap Protector

Install the bolts into the pre-tapped holes on the back of the compressor
section. Install a neoprene cap on each bolt. Refer to Figure 1-2 for the
locations of the pre-tapped holes.

RS-232 Communications

8600 Series freezers have a data communications interface. The factory
default setting is RS-232.

The wiring identification for the interface is
shown in Figure 1-10. One nine pin, sub
"D" style connector is located on the back
of the freezer. See Figure 1-2 for the
location of the connector on the freezer.

Figure 1-10. RS-232 Interface

The freezer transmits temperature information every 60 minutes. A
standard DB9 serial extension cable can be used to connect the freezer to a
serial device. Some serial devices may require a null modem adapter.

The data transfer sequence is transmitted in the following format. X refers
to numerical temperature data.

(NUL) (-) XXX (SP) C (SP) (Error Message) (SP) (LF) (CR) (EOT) (SP)

In the event of a CNTRLFAIL, Er07, or the control probe is out of range
error, the numerical temperature data (XXX) in the transmission would be
replaced by T_ERR.

If no alarm condition exists, spaces will be sent. A total of 20 characters
will be sent.

This condition is created when the high stage compressor and fans run for
30 minutes and are not capable of cooling the interstage heat exchanger to
the proper temperature. Under this condition, the high stage compressor
and fans will turn off after 30 minutes and an audible and visual alarm will
occur along with the "HS SYST FAIL" message in the LED message

PREVENTIVE MAINTENANCE

Freezers

our equipment has been thoroughly tested and calibrated before shipment. Regular preventive maintenance is important to keep your

Y

nit functioning properly. The operator should perform routine cleaning and maintenance on a regular basis. For maximum

u

erformance and efficiency, it is recommended that the unit be checked and calibrated periodically by a qualified service technician.

p

The following is a condensed list of preventive maintenance requirements. See the specified section of the instruction manual for
further details.

We have qualified service technicians, using NIST traceable instruments, available in many areas. For more information on Preventive
Maintenance or Extended Warranties, please contact the Technical Services Department.

Cleaning and calibration adjustment intervals are dependent upon use, environmental conditions and accuracy required.

Tips:

• Fill an upright by starting at the bottom near the probe and add racks to one shelf at a time. Allow freezer to recover to set point
between shelves.

• Fill a chest by starting at the left side near the probe. Filling with room temperature racks will result in a long pull-down time.

• Fill unit with frozen product to help overall performance; frozen water jugs, for example.

• Always make certain the vacuum relief port is free of frost and ice, to allow for timely re-entry into the freezer after a door
opening.

Install Injection Assembly

Note Before installation of BUS components, make sure the power to the

freezer is disconnected, the battery switch is turned off (O) and the freezer
has warmed to ambient temperature. s

The built-in BUS (back up system) will keep the freezer chamber
temperature below the critical level in the event of a power or equipment
failure. If power to the freezer fails, or temperature increases to the back up
alarm set point, the BUS injects liquefied gas into the chamber to keep the
chamber temperature within the specified range.

The BUS operates on an internal 12-volt, rechargeable battery which is
kept charged during normal operation by the integral battery charger.

Figure 6-1. Mounting location

1. Locate the mounting hole for installing the injection tee assembly. See
Figure 6-1.

Note Cover open end of injection assembly with tape to keep insulation
from entering the nipple.

2. Slide 3/8” flatwasher over open end of nipple.

Installation category (overvoltage category) defines the level of transient overvoltage which the instrument is designed to withstand safely. It

depends on the nature of the electricity supply and its overvoltage protection means. For example, in CAT II which is the category used for

instruments in installations supplied from a supply comparable to public mains such as hospital and research laboratories and most industrial

laboratories, the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V supply.

2

Pollution degree describes the amount of conductive pollution present in the operating environment. Pollution degree 2 assumes that

normally only non-conductive pollution such as dust occurs with the exception of occasional conductivity caused by condensation.
