1.4 RECEIVING AND SHIPPING DAMAGE HANDLING

Each unit is carefully inspected to meet our high standard quality assurance policy before it ships to you. Unfortunately, shipping damage can happen during transportation to you. There are two general types of shipping damage. The first is visible damage. This type of damage includes visible loss, damage, shortage or any external evidence of loss or damage that is visible at time of delivery. This type of damage must be noted in detail on your delivery receipt. Make sure the driver signs and dates the delivery receipt, acknowledging the damages. We also recommend taking many pictures to demonstrate and document the damaged area(s). This must happen at the time of delivery. Keep a copy for your records and send another to the carrier’s damage claims department along with a formal request for an inspection report. Follow up with a phone call. Their contact information can be found on the carrier’s web site.
The second type of shipping damage is concealed damage. This type of damage will probably not be apparent at time of delivery and may not be discovered until unpacking and inspecting the unit. Remember, time is of the essence. You should unpack and inspect the unit as soon as possible. Each day that passes reduces the likelihood that the carrier will pay the claim. As soon as the concealed damage is discovered, stop unpacking and retain all packing materials. Take many pictures to demonstrate and document the concealed damage area(s). Contact the carrier by phone to report the claim. Note the date and time and person you spoke with. Get a claim number. Follow up with a written letter referencing the claim number and including a formal request for an inspection. Again, consult the carrier’s website for specific claim instructions and follow them precisely.
AS STATED ABOVE, THE CARRIER IS YOUR SOLE SOURCE FOR SATISFACTION OF A DAMAGE CLAIM. UNDER NO CIRCUMSTANCES SHOULD THE MERCHANDISE BE RETURNED TO THE MANUFACTURER. NO RETURNS WILL BE ACCEPTED WITHOUT PRIOR AUTHORIZATION.

INSTALLATION

2.1 UNPACKING

• A fork truck or pallet jack is required to remove the unit from the pallet. Remove packaging for unobstructed access under the unit.
• When using a fork truck, place forks under the unit from the front or rear of the unit. Forks should be set as wide as possible for stability. DO NOT place forks in the center of the unit to avoid tip over.
• When using a pallet jack, align forks directly in front or back of the unit, making sure to avoid the casters. Lift forks to the same height as the top runners supporting the unit. Slide unit straight forward or backward until casters are free from the skid, then lower unit to the floor.

Remove foam/cardboard shipping supports from the inside of the chamber prior to powering on unit. Make sure to do this after the unit is set in place to prevent damage.
2.2 GENERAL RECOMMENDATIONS

• Allow the unit to come to room temperature before starting. The high temperature alarm will sound until the unit is able to bring the internal temperature down from initial start-up.
• Allow for the set point to be reached and for the unit to stabilize before storing products.
• Do not overload the unit.
• Only store items within drawers or baskets. Products stacked against walls or doors may obstruct air flow and impair the performance of unit.

2.3 LOCATION AND FUNCTIONAL INSPECTION
Ambient conditions: Unlike a household units, this equipment is designed for scientific and medical applications. Many components are heavy duty and optimized to meet demanding temperature performance requirements. Therefore, the sounds generated from its operation may not be accepted by everyone in the room. Please take the operation sound factor into consideration and locate the unit accordingly.
Please ensure the ambient temperature is typically climate-controlled, +18°C to +26°C (+65°F to +78°F), <70% RH, to ensure efficiency and strong thermal performances. Some ambient state excursions are acceptable, but performance may be impacted if used in other environmental conditions. Please refer to the Product Specifications section of this manual for guidance.
Clearance Space: This model requires a minimum of 2 clearance space around the unit. This will allow good airflow and access to the unit for periodic maintenance, or service.
The cabinet must be located within reach of an outlet that has appropriate power supply as listed above with a protective earth ground. The outlet should be easily accessible when installation is complete as this is the only method for powering off the equipment.
Do not stack items on top of the unit. This can damage sheet metal components and block airflow, compromising performance.

2.4 LEVELING AND ANCHOR INSTALLATION (Anchors are optional accessories)
Leveling
Ensure that the placement chosen for installation has a level floor. The unit must be level side to side and front to back. If the unit is not level, corrections can be made using hard and durable shim stock (hard plastic or corrosion resistant metal sheets) under the casters. Ensure that the caster locks are engaged.
If the unit is not level, automated door closure and drawer operation may be negatively impacted.

Anchor Brackets (optional)
It is highly recommended that the system is anchored in some manner to resist tip over. Since different installations have different requirement, the optional anchor system may not meet your requirements.
Anchors brackets provide tip over resistance only. This is not a seismic rated system. Application performance is not warranted since the installation is not controlled by Horizon Scientific, Inc.

Anchors brackets are attached to the unit using the exterior, rear caster bolts. One anchor bracket is required for each rear caster. The following process is suggested but on-site conditions may require adaptation. Only qualified technicians should perform this operation.
The anchor bolt and type must be selected and installed by a qualified, on- site technician. It is recommended that ¼” diameter stainless steel bolts and washers be used for installation to prevent corrosion. The anchor bracket provides flexibility to accommodate most floors, but shims can be used if necessary.

1. On each of the rear casters, remove the rear most, outboard bolt. Be careful to retain the washers.
2. Position an anchor bracket on each side and reuse the removed bolts to attach the bracket. Firmly tighten the bolts.
3. Position the unit exactly as it is to be installed in the facility.
4. Mark the slot position on the floor for each side once the installation position is finalized.
5. Drill and install floor anchor hardware as appropriate on one anchor bracket without fully tightening the floor anchor bolt.
6. Verify the position of the remaining slot is still properly aligned.
7. Drill and install the second set of floor anchor hardware and anchor bracket.
8. Firmly tighten both anchor bolts.

2.5 DOOR ALIGNMENT
Verify that each door is level and opens and closes easily. If adjustment is needed, the bolts for the top hinge bracket may be loosened and moved by a qualified technician to properly align the door.

2.6 DRAWERS
Product Storage Setup

The cabinet comes standard with repositionable and removable stainless-steel drawers supported by high capacity sliding rails. Pilasters are factory installed and allow user to select spacing between each drawer. Drawers are rated to 65 lbs. (29.5 kg) each.
Drawers are designed for a precision fit; it is critical that they are properly installed and locked securely into position.
CAUTION: The drawers and drawer hardware present pinch points when assembling and disassembling.

Drawer Installation and Repositioning

1. Position support bracket with both hooks inserted completely into the front and back pilaster strips at the same height (level horizontally).
2. Engage white locking levers at front and back of bracket, making sure bracket is properly secured to both pilasters.
3. Repeat steps 1-2 for opposing support bracket, making sure brackets are at same height on left and right to support both sides of the tray.
4. To remove and replace drawers:
   i. Depress locking tabs on drawer sides (alternatively, the integral slide locks can be used to remove the inner slide race while it stays attached to the drawer)
   ii. Pull up front of drawer out of vertical tabs
   iii. Slide drawer forward out of horizontal tabs
   iv. To replace drawer, reverse the process and reset locking tabs when installed

2.7 ELECTRICAL COMPONENTS
Remote Alarms Contacts
The remote alarm contacts terminal block is located at the back of the cabinet as shown. Terminals are labeled NC (normally closed), COM (Common), and NO (normally open). Terminal connections are rated per the included specification table. End user is responsible for proper field installation.

Remote Alarm Contact (RAC) Terminal Block: Black and White – Normally Closed, Green and White – Normally Opened
RS485 terminals
The RS485 terminals are located on the top of the unit. Connect wires to the -Tx/Rx, +Tx/Rx, and GND terminals per the label.
2.8 ELECTRICAL INSTALLATION

Check the proposed external power outlet/supply to be used to ensure that the voltage, phase and current carrying capacity of the circuit from the electrical panel correspond to the requirements of the cabinet.
The supply circuit to this cabinet must conform to NEC (National Electrical Code). Consult the cabinet Serial- Data plate for voltage, cycle, phase, and amperage requirements before making connection.
Supply voltage should not vary more than 10% from the serial plate ratings
DO NOT connect this equipment to a GFI (Ground Fault Interrupt) circuit.
Do not use an extension cord or any multi-outlet strip or plug. Using such devices can lead to insufficient power and component failure, such as the compressor or starting components.
If the power cord is damaged, it should be replaced immediately by an authorized service technician.
Be sure your unit is properly grounded. Use the 3-prong plug provided into a 3-prong grounded outlet. Unless the above grounding method is followed, you are not protected against severe or lethal shock in the event of a short circuit of an electrical component or wiring of the unit.
2.9 CHART RECORDER (If included)
Caution: Do not lift the pen arm in order to install or remove chart paper. This will bend the pen arm and may prevent the arm from providing enough pressure to draw a legible mark. Ensure that the current time and day is aligned with the line groove when it is installed.
Chart recorder operation and paper replacement

1. Press and hold (#3) button approximately 1 second. When pen arm moves, release button. The LED will flash.
2. When the pen arm stops moving (off the paper), unscrew and remove the chart knob from the center of the paper.
3. Place chart paper on the recorder.
4. Rotate the paper so the correct time is aligned with the time-line groove.
5. Make sure to hold chart paper in place while securing chart knob is fully tightened. (NOTE: only hand tighten chart knob. Over tightening can damage the chart motor gearbox).
6. Press and hold (#3) button approximately 1 second until pen arm begins moving. Make sure it is writing on the paper, if not may need to be adjusted to properly contact the paper. Also make sure it stops at the correct temperature.
7. Calibrate the recorder to match the temperature if needed and close the chart recorder door.
   

Chart recorder power supply
The chart recorder uses AC power during normal operation. If power fails, the recorder continues to record the temperature with the supplied 9V battery back-up. The light on the chart recorder indicates the power status:

• LED indicator shows green continually when main power is functioning, and the battery is charged.
• LED indicator shows flashes green to indicate that either the main power has failed, and the recorder is receiving power only from the battery back-up, or the main power is on, and the battery needs to be replaced.
• LED indicator flashes during the chart paper changing mode.

2.10 TEMPERATURE PROBES

A primary temperature monitoring probe (a bottle containing a glycerol mixture or a thermally equivalent a solid ballast) has been provided with the unit. This probe is located on the right side, near the top of the cabinet interior. The glycerol or solid ballasts are designed to simulate the temperature of stored product during normal operation. Failure to maintain a full probe bottle may cause the display to report temperatures that do not represent the stored product temperature accurately.

A secondary temperature monitoring probe (solid ballast) has also been provided with the unit. This probe is located on the right side, near the bottom of the cabinet interior.

2.11 External PROBE access port
This unit is equipped with a ¾” (19 mm) port that can be used for external monitoring devices. This port is located on the back of the unit. Remove the rubber plug in the port for routing.

2.12 BATTERY BACKUP

The controller comes standard with a battery backup feature that allows the controller to maintain temperature monitoring and alarms even if the main power is lost.
To activate the battery backup, insert the 5A glass fuse into the battery fuse holder at the top of the unit and secure the thumbscrew cap. This fuse is shipped lose so the batteries are not discharged during transport or storage.
NOTE: The unit cannot cool without main power, but the controller will continue to display and log alarms until the battery backup is discharged.
Note: A low battery voltage alarm may sound after powering on the unit. The alarm may be muted, and it may be necessary for the batteries to charge properly up to 1 hour before the alarm can be cleared.
2.13 INITIAL POWER UP AND OPERATION

Once all elements of the installation and any on site IQ (Installation Qualification) have been completed, your unit is ready for startup. Simply plug in the unit into a grounded outlet that meets the electrical requirements, and the unit will automatically begin the startup sequence.
These units employ an advanced PID, programmable controller to modulate the temperature within the cabinet. The controller, which is located on the canopy of the unit, is factory set.
Each time power is applied to the unit, the controller records a “power loss alarm” condition to document each time the controller is powered on. This alarm can be cleared immediately as it does not impact the function of the unit. Refer to the next section for details on the operation of the controller.

MAINTENANCE

Observe all Warning Labels. Disconnect power to eliminate injury from electrical shock when servicing equipment or cleaning.
Important: It is critical that cleaning recommendations are followed to ensure optimal performance and longevity of the unit.

5.1 INSPECTION AND SERVICING
Periodic inspections
Every 3 months or as required:

• Check that the condenser coil is free of obstruction.

Every 6 months or as required:

• Check the controller backup battery status
• Clean the condenser coil
• Check the door gasket for proper seal
• Check drain line from evaporator pan for blockage or leaks.

Battery replacement
Controller backup batteries are 2x 12V rechargeable lead acid batteries connected in series to provide 24V DC power to the controller. If batteries must be replaced, replace both cells at the same time to ensure proper charging and optimum power availability.

1. Disconnect the main power cord from the wall.
2. Remove the battery fuse from the top of the unit.
3. Remove the top cover from the unit.
4. Locate the batteries near the right wall of the cabinet, held in place with a metal bracket.
5. Disconnect the wiring from the 4 battery terminals, noting the polarity of each connection.
6. Remove the 4 screws holding the metal bracket and lift the bracket away from the batteries.
7. Remove both batteries. Replace with new batteries in the same location and orientation.
8. Reverse the procedure above to restart the unit.
9. Note: a low battery voltage alarm may sound after powering on with new batteries. Wait 1 hour for the batteries to charge properly, then clear the alarm. If the battery voltage alarm persists, contact technical service.

Cleaning

• Never use abrasive cleaners or instruments (steel pads, wire brushes, etc.) on stainless steel interior or powder coated exterior.
• Never use acid-based cleaners, which will damage the stainless finish. Warm soapy water is best, but if cleaning solution is required, use only alkaline based cleaners.
• Avoid chlorides during cleaning which could damage the stainless-steel finish. Chlorides are commonly found in hard water, salts, and household or industrial cleaners. If cleaners with chlorides are used, rinse with clean water and dry thoroughly.
• Gaskets should be cleaned only with warm soapy water. Cleaning products could damage gaskets or cause them to embrittle over time. Never use tools which could cut or tear the gasket.
• The condenser is an anti-fouling design, but inspections should be performed quarterly, and the condenser cleaned as necessary to maintain good thermal transfer properties. A soft bristle can be used to loosen these particles that are attached to the grid so that they may be removed with a vacuum cleaner. Care must be taken not to damage the condenser. It is recommended that the condenser be cleaned at least once every 6 months.
• All moving parts have been permanently lubricated and will generally require no maintenance.

Important: Failure to keep the condenser coil clean and clear of obstructions could result in poor performance and possibly damage to the compressor.
