Installation Procedures

NOTE: Installation and maintenance to be performed only

by qualied personnel who are familiar with local codes and regulations and are experienced with this type of equipment.

CAUTION: Make sure all power sources are disconnected

before any service work is done on units.

A.) Inspect packaging/unit for shipping damage

B.) Review the space and location requirements provided for your

method of installation.

C.) Follow installation instructions listed in method #1 or #2

Installation Method #1

Top Installation (See FIGURES 4, 5 and 6)

This installation method is the recommended installation method in applications where it is feasible.

In order to install a unit using this method, you will need to provide cutout slots for the “arms.” The unit should be placed on the wall prior to setting and securing the roof of the box.

Please use the following guidelines when completing the installation in this manner.

1. You will need to provide nished slots with the appropriate dimensions in the box wall.

2. The slots can straddle a seam but they should not be on a seam. See FIGURE 4.

3. The cut-out sections should not be placed in a location where they would interfere with any cam locks.

4. It is preferred that a cam lock be placed in between the cutouts to give additional support

See FIGURES 5 and 6.

5. The unit will need to be lifted to the appropriate height and inserted into the open slots. The bottom of the unit should be temporarily supported during the remainder of the installation process (no portion of the unit should be supported by the bottom of the evaporator section as this WILL cause damage to the drain pan).

6. Set and secure the roof of the box and rmly attach the unit to the box and carefully seal all seams and penetration points.

Installation Method #2

Side Installation (See FIGURES 7, 8, and 9)

This installation method is intended for applications that have height restrictions that do not allow the unit to be installed from above (see method #1) and installations into pre-existing boxes where it is impractical to remove the roof.

In order to install a unit using this method, you must provide an additional “plug” section of the box to ll in the open space between evaporator arms after installation. This section should contain cam locks to anchor it in place.

Please use the following guidelines when completing the installation in this manner.

1. Provide a nished opening with the appropriate dimensions

from FIGURE

The cut-out section should not be placed in a location where it

would degrade the structural integrity of the box (should not

interfere with cam locks)

3. The unit will need to be lifted to the appropriate height and

inserted into the open slot. The bottom of the unit should be temporarily supported during the remainder of the installation process (no portion of the unit should be supported by the bottom of the evaporator section as this WILL cause damage to the drain pan).

4. You should use cam locks to re-connect the “plug” section after

installing the unit, rmly attach the unit to the box and carefully seal all seams.

4. Ensure that the condensing unit airow is not obstructed after removing the temporary support.

5. Do not obstruct the evaporator airow with shelving. The area below the evaporator should be left completely open.

6. Connect unit to power supply through knock-out provided above electrical box using all local wiring codes.

7. Apply power to unit. All controls are preset to factory default settings. See Table 1 (next page).

8. Check the unit for proper operation.

FIGUR E 12: Mounting Holes | Side View

Mounting

The system requires two through-bolts to be used to connect to the roof panel. A minimum of four through-bolts should be used to connect to the side panel of the box. The opposite side of the box should be reinforced with wood or metal to prevent the bolts from pulling through the panel. See FIGURES 12, 13 and 14 for locations.

Through bolts should be insulated or non-conductive to prevent sweating. All penetrations to the box should be caulked to prevent

moisture from entering the box.

1. Install two through bolts to secure the unit to the wall. The inside of the box should be reinforced with wood or metal for proper when mounting of the unit to the box with through bolts.

2. Install and secure the roof of the box. Inside the box, provisions have been made to secure the evaporator section to the roof panel with through bolts.

3. The area between the evaporator section and the roof panel should be caulked to meet NSF codes. In addition, the openings where the unit was lowered into the box panel should be caulked to prevent any inltration from the outside area into the box.

PRO3 Side Mount Packaged Refrigeration System

Electrical Connection

1. Refer to all local codes for proper connection.

2. A knock-out is provided for 1" conduit on the side of the

condensing unit section above the electrical box. See FIGURE 12.

3. Wire will be brought into the electrical box through the

bottom of the electrical box and connected to the top of the contactor.

Refrigeration Sequence of Operation

1. Power is provided to the temperature control, compressor

contactor and cooler evaporator fans.

2. The temperature controller closes and energizes the

compressor contactor, starting the compressor, evaporator and condenser fan(s).

3. When the system reaches the desired box temperature, the

temperature control will de-energize the compressor contactor. Evaporator fans will continue to operate at this point.

4. When the xture temperature rises above the set point

and minimum o-time has elapsed, the temperature control will close and re-energize the compressor contactor.

Coolers: Air-defrost Operation

Air defrost units are pre-programmed for 4 defrost per day. These periods are reprogrammable. When the coil temperature reaches 38°F, the control will terminate the defrost cycle.

For programming information see pages 7-16.

Cooler with Electric Defrost and Freezer Temperature/Defrost Control

PRO3 packaged refrigeration system cooler with electric defrost and freezer units come factory equipped with an electronic temperature/ defrost control.

For programming information see pages 7-16.

Cooler with Electric Defrost and Freezer Sequence of Operation

Power is provided to the temperature control and compressor contactor. The drain line heater as well as the crankcase heaters will also have continuous power supplied to them.

The temperature controller energizes the compressor contactor, starting the compressor and condenser fan(s). The evaporator fans will be energized by the electronic controller.

When the system reaches the desired box temperature, the temperature control will de-energize the compressor contactor and the evaporator fans.

When the temperature rises above the set point and minimum otime (4 minutes) has elapsed, the temperature control will close and re-energize the compressor contactor.

1. During normal operation, at the preset times of day, the temperature/defrost control will de-energize the compressor contactor and evaporator fans and energize the defrost heaters. These functions are controlled through relays on the controller.

2. When the coil has defrosted fully and has reached the preset coil temperature (as sensed by the coil temperature sensor) the defrost heater de-energizes and the fan delay and drip sequences begin.

3. The temperature/defrost control energizes the compressor contactor, starting the compressor and condenser fan(s).

4. Freezer evaporator fans will be energized by the temperature/ defrost control when the coil temperature reaches 35°F or fan delay time has elapsed.

Service Information

All PRO3 packaged refrigeration system units are designed for maximum durability, reliability and simplicity. The PRO3 packaged refrigeration system comes to you ready for operation, fully charged and with all controls preset at the factory. The following information is provided as an aid in the event that service is required.

Maintenance

The evaporator section of a PRO3 packaged refrigeration system should be checked at least once for proper defrosting because the amount and pattern of frosting can vary greatly.

The frost build-up is dependent on the temperature of the room, the type of product being stored, how often new product is brought into the room and percentage of time the door to the room is open. It may be necessary to periodically change the number of defrost cycles or adjust the duration of defrost.

System Standard Maintenance Guidelines

After rst year of operation and under normal usage, maintenance should cover the following items at least once every six months:

1. Check and tighten ALL electrical connections.

2. Check all wiring and insulators.

3. Check contactors for proper operation and for worn contact points.

4. Check all fan motors. Tighten motor mount bolts/ nuts and tighten fan set screws.

5. Clean the condenser coil surface.

6. Check the operation of the control system. Make certain all safety controls are operating properly.

7. Check all defrost controls for proper function.

8. Clean the evaporator coil surface.

9. Clean the drain pan and check the drain pan and drain line for proper drainage.

CAUTION: Unit is critically charged, care must be taken not to reduce the system refrigerant charge while taking pressure readings. Technician must compensate for any refrigerant that might escape the unit into the gauge tubing.
