2 Safety Precautions

In this manual and on labels attached to this product, the words WARNING and CAUTION mean the following:

• WARNING: a potentially hazardous situation which, if not

avoided, could result in serious injury or death.

• CAUTION: a potentially hazardous situation which, if not

avoided, may result in minor or moderate injury or damage to the equipment.

Before installing, using or maintaining this product, please be sure to read this manual and product warning labels carefully. Failure to follow these instructions may cause this product to malfunction, which could result in injury or damage.

The following important safety precautions apply to this product:

• Use this product only in the way described in the product

literature and in this manual. Before using it, verify that this product is suitable for its intended use.

• Do not modify system components, especially the controller.

Use OEM exact replacement equipment or parts. Before use, confirm that the product has not been altered in any way.

• Your unit must be properly grounded in conformity with

national and local electrical codes. Never connect the unit to overloaded power sources.

• Disconnect the unit from all power sources before cleaning,

troubleshooting, or performing other maintenance on the product or its controls.

3 Pre-Installation

3.1 Unpacking

At delivery, examine the exterior for physical damage while the carrier’s representative is present. If exterior damage is present, carefully unpack and inspect the unit and all accessories for damage.

If there is no exterior damage, unpack and inspect the equipment within five days of delivery. If you find any damage, keep the packing materials and immediately report the damage to the carrier. Do not return goods to Revco without written authorization. When submitting a claim for shipping damage, request that the carrier inspect the shipping container and equipment.

Installation and Operation

Laboratory Refrigerators

4 Installation

Do not exceed the electrical and temperature ratings.

CAUTION! Improper operation of the equipment could result in dangerous conditions. To preclude hazard and minimize risk, follow all instructions and operate within design limits noted on the dataplate.

4.1 Location

Install the unit in a level area free from vibration with a minimum of 6 inches of space on the sides and rear and 12 inches at the top.

Do not position the equipment in direct sunlight or near heating diffusers, radiators, or other sources of heat. The ambient temperature range at the location must be 59 to 90°F (15 to 32°C).

4.2 Wiring

CAUTION! Connect the equipment to the correct

power source. Incorrect voltage can result in severe damage to the equipment.

DANGER! For personal safety and trouble-free operation, this unit must be properly grounded before it is used. Failure to ground the equipment may cause personal injury or damage to the equipment. Always conform to the National Electrical Code and local codes. Do not connect unit to already overloaded power lines.

Always connect the equipment to a dedicated (separate) circuit. Electrical codes require fuse or circuit breaker protection for branch circuit conductors. Use time delay fuses for #12 AWG circuits.

Chromatography refrigerators are equipped with a duplex vaporproof interior outlet with a maximum of 4 amps per receptacle.

The wiring schematic is attached to the back of the cabinet.

4.4 Door Seal

To check the door seal, complete the following steps:

1. Open the door.

2. Insert a strip of paper (a couple of inches wide) between the door gasket and the cabinet flange and close the door.

3. Slowly pull the paper strip from the outside. You should feel some resistance.

4. Repeat this test at 4-inch intervals around the door. If the door does not seal properly, replace the gasket.

CAUTION! Door seal integrity is critical for refrigerators and freezers. A loose fitting gasket allows moist air to be drawn into the cabinet, resulting in quicker frost buildup on the evaporator coil, longer running time, poor temperature maintenance, and increased operation cost.

4.5 Solid Doors

Solid doors stay open if opened 90 degrees. Solid door spring tension cannot be adjusted.

4.6 Glass Doors

Glass door tension can be adjusted. Check the door operation. If the self-closing doors do not work properly, make sure the unit is level. If the unit is level and the doors do not self-close, adjust the door tension.

There are two types of glass doors: hinged and sliding. Refer to the sections below that apply to your unit.

CAUTION! Do not overtighten the tension as damage to the equipment can result.

WARNING! Disconnect equipment from main power before attempting any maintenance to equipment or its controls.

4.3 Leveling

The unit must be level. Rotate the leveling screws, located under the front corners of the unit, until the unit is level. If the floor is seriously out of level, you may need to shim the corners with thin sheets of metal.

Note: Use thin sheets of metal to level units equipped with

optional casters.

Installation and Operation

Laboratory Refrigerators

4.6.1 Hinged Glass Doors

On models with hinged glass doors, you can use a regular screwdriver to adjust spring tension and center each door on its frame. The adjustment screws (“torque” for tension and “sag” for door placement) are located on the bottom hinge bracket (shown below in Figure 1).

Hinged glass doors can be propped open with metal braces at the bottom hinges. Open the door 90 degrees or until you feel some resistance. Push the door open past the resistance and the metal braces engage. To close the door, push it toward the unit (past the resistance).

Adjustments

4.6.2 Sliding Glass Doors

To adjust the tension on the 45 ft

sliding glass door model,

complete the following steps:

1. Lift the door up and pull the bottom toward you.

Note: The tracks at the bottom are loose to conform to NSF

standards. They remove easily for cleaning.

4.7 Final Checks

Before start up, complete the following steps:

1. Make sure that the unit is free of all wood or cardboard shipping materials, both inside and outside.

2. Verify that the unit is connected to a dedicated circuit.

CAUTION! Connect the equipment to a separate, dedicated, power source. Power fluctuations can result in severe damage to the equipment.

5 Shelves and Drawer Slides

For safety in shipping, the shelves are packaged and secured inside the cabinet. Insert the shelf support hangers (included with the shelves) into the built-in pilasters (located on the inside walls of the cabinet interior) at the desired locations. Position the shelves on the flat supports (refer to Figure 2).

Note: The number of shelves supplied per cabinet varies

according to type of unit and size of cabinet.

2. Lower the door so it rests on the floor, be careful not to disconnect the spring closure.

3. The self-closer located across the top of the door has several slots into which the end hook can be inserted. The door tension varies depending on the slot in which the hook is inserted.

4. Replace the door on its tracks. To install the door, lift the door up and into the top then push in and fit the bottom of the door into the bottom track. Make sure the self-closer runs in the pulleys at the top of the door.

4.6.3 Locking and Unlocking Sliding Glass Doors

The sliding glass doors can be locked in both the open and the closed position. To lock these doors, complete the following steps:

1. Locate the door lock at the top center of the door frame.

2. Engage the lock by moving the mechanism up against the strike located in the perimeter frame.

3. Insert the key, which resembles a small Allen wrench, into the lock cylinder and turn clockwise until tight.

4. Reverse these steps to unlock the door.

Figure 2. Shelf Support Hanger

Drawer slides (standard for pharmacy refrigerators) are similar but have a small wire safety clip at the front pilaster which prevents the slides from falling when the drawers are removed. To change the position of the drawer slides, complete the following steps:

1. Locate the safety clip.

2. Slip your fingernail or a small screwdriver under the bottom of the wire clip and pry it out toward the inside of the refrigerator.

3. Lift up the slide at front. The slide is free to move from the front pilaster.

4. The drawer slide must be removed from the rear pilaster at approximately a 45 degree angle toward the center of the cabinet.

5. Pull the slide toward the front of the cabinet.

For more information on removing and reinstalling the drawers, refer to Section 10 on page 9.
