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.

Section 2 Calibrate

Calibrate Mode

Calibrate Control Probe

Once the freezer has stabilized, the control probe may need to be
calibrated. Calibration frequency is dependent on use, ambient conditions
and accuracy required. A good laboratory practice would require at least an
annual calibration check. On new installations, all parameters should be
checked after the stabilization period.

Note Before making any calibration or adjustments to the unit, it is
imperative that all reference instruments be properly calibrated.

Plug a type T thermocouple reader into the receptacle located inside the
lower door (see Figures 1-4 and 1-6). Compare the control temperature
set point to the temperature of the measuring device. See Chart 2-1 at the
end of this section for more detail.

1. Press the Mode key until the Calibrate indicator lights.

2. Press the right arrow until “CONT T = -XX.X” appears in the message
center.

3. Press up/down arrow to match the display to calibrated instrument.
