To avoid the possibility of electrical shock, open and tag all disconnects before installing this equipment. Failure to do so could result in severe personal injury.

INTRODUCTION

An accessory long line check valve must be installed for:

1.Any 025-030 size dual circuit unit where the evapora- tor is located higher than the condensing unit and the linear line length exceeds 55 ft (16.8 m).

2.Any size dual or single circuit unit with linear line length of 100 ft (30.5 m) or more.

The kit consists of a liquid line check valve and a bypass check valve to prevent charge migration to compressor.

INSTALLATION

CAUTION

For all units with liquid lines of 100 ft (30.5 m) or more or any 025-030 size dual circuit unit application where evapo- rator is located higher than the condensing unit and liquid lines exceed 55 feet (16.8 m), a long line check valve must be installed to prevent compressor failure. The long line check valve accessory must be mounted in the liquid line as close as possible to the condensing unit.

The long line check valve accessory must be mounted in the liquid line near the condensing unit. The valve is brazed into the liquid line. Fitting adapters may be required to connect the check valve to the liquid line. The valve may be mounted in any orientation, horizontally or vertically. See Fig. 1 for dimen- sions. Figure 2 shows the location of the check valves on a rooftop installation. Figure 3 shows the location of the check valves on a ground level installation.
