GENERAL

INTENDED USE

Designed to meet the demanding requirements for scientific and laboratory research. Advanced engineered design incorporates the latest in cabinet, refrigeration, temperature control and monitoring features. Provides energy efficient, convenient, safe and reliable performance for optimal temperature environments necessary for a wide range of plant science, life science, pharmacy, biological, medical, clinical and industrial applications.

TECHNICAL SPECIFICATION

Voltage supply: 115V 60HZ 1 phase Maximum fuse size: 20A Total amp draw: 13.6A Max set point : 44 C degrees

INSPECTION

When the equipment is received, all items should be carefully checked against the bill of lading to insure all crates and cartons have been received. All units should be inspected for concealed damage by uncrating the units immediately. If any damage is found, it should be reported to the carrier at once, and a claim should be filed with the carrier. This equipment has been inspected and tested in the manufacturing facility and has been crated in accordance with transportation rules and guidelines. Manufacturer is not responsible for freight loss or damage.

LOCATION

The cabinet should be located within reach of an outlet that has 115V 60HZ 20A with a protective earth ground. The outlet should be easily accessible when installation is complete. The refrigeration system located at the top of the cabinet requires free air access for proper operation. Allow a minimum four-inch clearance on the top, rear, and sides of the cabinet. The cabinet should also be leveled when it is placed in its permanent location. Do not stack items on top of the unit. Vibration during shipping and handling may loosen mechanical connections. Check all connections during installation. Check all wiring, piping and fasteners. This unit has been designed for 75 deg with 50%RH at up to 2000 Meter elevation. If equipment is not used for its designed manner specified by the manufacturer, the protection provided by the equipment may be impaired.

WARNINGS AND CAUTIONS

• Do not modify cabinet construction or associated equipment assemblies.

• Do not remove labeling or information supplied with the unit.

Warning: Electric Shock Hazard. Do Not Remove top electrical cover. Contact a qualified service representative.

INSTALLATION Door Alignment - If for some reason the doors are not squared up on the cabinet, the

doors can be adjusted. Opening the door(s) and loosening the screws that hold both the top and bottom hinges to the cabinet can accomplish this. After adjusting the door so that it is aligned correctly, tighten the screws to securely hold the hinges in place.

Reversing Swing of Solid Door - Complete the following steps if reversing the swing of the solid door(s) is desired. These steps apply to both refrigerators and freezers.

1. With a one, two, or three door model, first open the door and locate the screws holding the hinges and door in position.

2. Two people are recommended to make this change. One person should hold the door at a 90° angle to the cabinet while the other person removes the screws holding the door to the cabinet. The normal installation at the factory is to have the spring loaded door-

closing mechanism located at the bottom of the cabinet. When removing the spring

tension bracket from the cabinet bottom, be careful that it does not snap back. This may result in pinched fingers.

3. After the door(s) are removed, remove the door lock strike(s) from the cabinet by removing the two mounting screws.

4. Find the holes, drilled through the outer skin only, located on the opposite side of the door opening from where the hinges were previously located. Drill through the tapping plate found behind these holes using a 7/32" drill bit.

5. Turn the door over and align it to the cabinet so it will swing in the desired direction. The spring loaded door-closing hinge will now be located at the top of the reversed door. Mount the hinges to the cabinet using the holes that were drilled out in step 4, along with the previously removed screws. Check the door(s) to be certain that it is mounted squarely and that the gaskets seal properly around the door opening. The door can be adjusted by moving the top or bottom hinge slightly.

6. The original hinge holes can be filled with silicone, or with 1/4-20x3/4 pan head stainless steel screws if desired.

NOTE: Steps 7, 8 and 9 are only required with center mounted lock.

7. Locate the door lock strike by visually aligning it to the dead bolt lock in the door while the door is in the closed position. While holding the strike in position, mark the top, bottom, and edge of the strike on the cabinet wall or mullion with a pencil or fine point marker that will remain legible until completion of the task. Verify that the strike is positioned properly by assuring that it is aligned to the marks and hold it securely; open and close the door and extend and retract the dead bolt to make certain they clear without

touching. The strike cannot be adjusted after it is mounted.

8. Align the strike to the marks, which were made in step 7 and mark the centers of the holes for the mounting screws. Using a #20 drill bit, drill the holes you just marked

approximately one-half inch deep. Take care not to puncture the interior side of the cabinet. Note: If a #20 bit is not available, use a 5/32" drill bit.

9. Mount the door lock strike using the screws that were removed from the original position. The screws may have to be forced until the thread cutting tip has passed through the entire metal thickness. The original door strike holes can be filled with silicone, or with two 10-24x1/2 stainless steel pan head screws if desired.

Shelving Installation – Shelving and Lighting comes installed for your desired light option. To

change shelf locations disengage lock as shown in Detail A, slide bracket up and remove. To install insert shelf bracket tabs into pilaster and push down. Slide lock fully into hole.

Remote Alarms Contacts Access - The factory installed Remote alarm

contacts access box is located at the top of the cabinet behind the microprocessor control.

1. Remove the cover to access the terminal connections.

2. Select and knock-out a hole to run field leads into electrical box terminals.

3. The terminal block in the electrical box is labeled for “normally open” and “normally closed” activation. End user is responsible for proper field installation.

Terminal connections are rated for class II circuits only per NEC table 11(A). (Limited power source less than 30vac 8 Amp. max, see applicable notes in NEC).

2-10 volt DC Output, is located at the top of the

control box behind the microprocessor control, connect wires as per label (4-20 ma optional).

RS485 port - (Optional) terminal board for

RS485 port is located behind the cabinet façade, on the left hand side of the control box, connect wires as per label.

Duplex/ or European Outlet - (Optional) is located near the top of the interior cabinet

back. This is a 15 amp 115 volt duplex PN 88010300 with its own power supply cord. Duplex outlet power cord is wrapped up on the back of the cabinet top. Outlet is not interwired thru main cabinet supply and must be plugged into a 115 volt/ or 220/240V power supply. Locate cabinet within 8 feet of the wall receptacle.
