Remote Alarm Connection
These units are equipped with a remote alarm plug for the connection to a remote alarm network.
The remote alarm plug is installed at the back of the cabinet near the main power plug enclosure and it is wired
through a connection cable to the controller board.
Fig. 3
The Remote alarm contact is a Dry contact (low voltage: max 24VAc/VDc, 1A, SELV) and consist of three outputs:
C (Common)/N.O. (Normally Opened Circuit)/N.C. (Normally Closed Circuit).
For the external network connection, fasten directly the pins according to the remote alarm network conguration.
When an alarm occurs the contact relay switches from the N.C. position to N.O.

Controller Operation
In normal operation, the controller will display temperature in degrees Celsius. To change from Celsius to
Fahrenheit requires a programming key. Contact Vector Products Parts Department at 1-855-686-5592 for
part numbers and pricing.
CAUTION! Vector Lab Products does not authorize changing any critical operating parameters
as it can cause improper system operation and/or severe mechanical damage.Changing
operating parameters may result in Vector Lab Products voiding equipment warranty.
Refrigerators come pre-programmed with a 4 C (39.2 F) set point. Standard operating temperature at default is
4C to 6 C (39.2 F to 42.8 F)
If desired, the refrigerator’s set point can be adjusted within a 1 C to 12 C (33.8 F to 53.6F) range.
Freezers are pre-programmed with a –25 C (–13 F) set point. If desired, the freezer’s set point can be adjusted
within a –23 C to –10 C (-13 F to 14 F) range
All set points have a +2 C (+3.6 F) differential (r0 setting on the controller). The 2.2 C (3.6 F) differential means that
with a 4 C (39.2 F) set point, the compressor will turn off at 4 C (39.2 F) and turn on when it reaches 6C (42.8 F).
It is important to understand that the set point equals the compressor cut out.

8Vector Lab Products Refrigerators and Freezers
Locking/Unlocking of the Keypad
The temperature controller is defaulted to lock out after 30 seconds without a key being pressed and will display
“Loc”. To unlock the controller press the SET key for 1 second until “UnL” is displayed. The controller is now
unlocked.
Viewing/Adjusting the Set Point
With the controller unlocked, press and release the SET key. The current Set Point will populate. Use the UP &
DOWN arrows to the desired Set Point and again press the SET key to store.
Powering the Equipment ON.
Locate the power switch to the left of the controller and place in the ON position (I).
Controller Set Up
Upon power up your controller will alarm RTC. This is instructing you to program the TIME/DATE.
Press and release any key to silence the alarm.
Check that the controller is not locked (LOC). If locked press and hold any key for 1 second and (UNL) will
DISPLAY.

Vector Lab Products Refrigerators and Freezers 9
Controllers are preprogrammed to alarm at the following temperature:
REF: High alarm: 9 C (48.2 F), Low: 2 C (35.6 F)
FZR: High alarm: –15 C (5 F), Low: –35 C (–32 F)
All alarm points operate off of a set SP +/- (A1/LOW, A4/HIGH) strategy.
Alarms will automatically clear when the temperature rises above/below the alarm value plus the A11 parameter
value (Alarm offset) of 3. In the case of a refrigerator, which low alarms at 2 C, the alarm will clear once the
temperature rises to +2 C. Adversely, a refrigerator that enters into a high alarm at 9 C, will have the alarm clear
once the temperature reaches 6 C.
AL on the controller screen reports a Low Temperature Alarm.
AH on the controller screen reports a High Temperature Alarm.
Defrosting
Vector Lab Products refrigerators and freezers do not require manual defrost as they utilize a hot gas defrost cycle
to keep the evaporator coil frost free. The defrost cycle is typically always terminated when the evaporator probe
(Pb2) reads 8 C.
If the defrost probe (Pb2) experiences a failure, or is out of spec, the MAX time the unit will stay in a defrost cycle
is 15 minutes. If this occurs a dFd alarm will appear.
Upon termination of the defrost cycle, the compressor, condenser fan, and evaporator fan will remain off for
60seconds to allow for the melted frost to drip away from the evaporator coil.
Refrigerators enable an automatic defrost cycle every 10 hours
Freezers enable an automatic defrost every 6 hours.
Seeing as the cooling and defrost system are external to the cabinet, the stored product and cabinet temperature
should experience a minimal rise during the defrost cycle.
Door Switch
Each refrigerator and freezer door is equipped with a normally opened mechanical switch that recognizes when
the door is opened or closed. When the controller senses an interruption in the continuity of the door switch circuit,
the evaporator fan(s) and compressor will power down. If the door remains open for longer than 2 minutes the
controller will alternate between the temperature and an audible and visual (id) alarm will appear. Once the circuit
is closed the alarm will clear. If an (id) alarm appears with all doors closed troubleshoot the switch circuit.

Cleaning
Use non chlorine-based cleaners. Cleaners containing chlorine can cause staining and pitting of the stainless
steel.
Disconnect power to unit by turning the power switch off, located on the rear, right hand corner, and removing the
power cord from the receptacle.
The appliance is designed for medications, vaccines and laboratory product storage so it is important to keep
it clean. The equipment is thoroughly cleaned at the factory before being shipped. We recommend, however, to
clean the interior cabinet before the rst start up of the appliance.
Interior Cleaning
Using a sponge or soft cloth, clean unit with a non-abrasive, non-chlorinated, all-purpose detergent. Note: The
air plenum can be removed to clean it, as well as behind it. In addition, the shelves and slides should be cleaned
aswell.
Exterior Cleaning
Wipe stainless steel exterior with a soft cloth in the direction of grain as needed. Stainless steel polish may be
used to enhance the nish of the unit. The glass door and exterior parts may be cleaned with a soft cloth, window
cleaner or other non-abrasive cleaner.
Annual Cleaning
Removal of dust and other particulates from air intake areas and the condenser is important for proper operation.
Environments with large amounts of dust may require more frequent cleaning.
1. Disconnect power to unit by turning power switch off and removing power cord from receptacle.
2. The condenser can be accessed from rear for cleaning.
3. Inspect drain pan for any debris or obstruction in condensate pan.
4. Use a vacuum cleaner with brush attachment to clean condenser, compressor and related parts.
Refrigeration System
The Vector Lab Products refrigeration system is designed to give many years of trouble-free service. Except for
routine cleaning of the air-cooled condenser and related parts, the refrigeration system requires no service or
maintenance. Refrigerator utilize a capillary tube metering device while freezers utilize a thermal expansion valve.
Both systems are critically charged. Access ttings are not provided. Temporary piercing valves are required to work
on the refrigeration system. Due to the small charge size contained within these products, Vector Lab Products
does not recommend accessing the refrigeration system. If a sealed system failure is suspected, Vector Lab
Products recommends replacing the cooling system in its entirety.
