GENERAL

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 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.

CAUTION

• Do not modify cabinet construction or associated equipment assemblies.

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

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.

Shelving Installation - Locate shelf clips in bag inside cabinet, install in shelf

supports (4 per shelf)

1. Remote Alarms Contacts Access - The factory installed Remote

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

2. Remove the cover to access the terminal connections.

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

4. 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 inter-wired 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.

Access Port - (Optional) is provided with a spring loaded cover on the right hand side of the

cabinet.

HUMIDITY INSTALLATION (if applicable)

The water supply should have a dedicated shutoff valve and regulator installed. Connect the water supply to the humidifier (the operating pressure range is 10-60 psi). For best results, provide a source of reverse osmosis water with a resistance of .05 to 1.0mΩ, which will reduce the scale build up and cleaning frequency. Unit is equipped for water supply with 1/8” Male Pipe Threads. The humidifier reservoir water level may be adjusted by using the adjusting thumb screw located on the float valve (see below).

The humidifier is a precision built instrument that, given proper care, will provide years of dependable service. Cleaning the humidifier periodically is all that is required to insure proper operation. Depending on local water conditions, mineral solids and other matter may accumulate in various parts of the unit. These accumulations must be removed so that water flows freely for efficient operation. Failure to clean the humidifier may result in malfunction which will lead to repairs.

If higher humidity levels are unobtainable, loosen the reducing coupling clamp and remove reducing coupling boot and reducer PVC.

DRAIN INSTALLATION

The Stability Chamber has a floor drain in the bottom of the cabinet. A silicone drain stopper has been placed in this drain. The drain stopper will prevent undesirable liquids from running into the drain. The stopper can be removed if any possible liquids flowing into this drain are acceptable to go to the floor drain.
