F. Installation of Remote Condenser Unit

WARNING

1.Installation of remote condenser unit must be performed by properly trained and EPA-certified service personnel.

2.Failure to install the equipment within these guidelines may adversely affect safety, performance, component life, and warranty coverage.

1.Checks Before Installation

1)Remove the shipping carton, tape, and packing material.

2)Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the fan blade moves freely.

2.Location

CAUTION

The remote condenser unit is intended for outdoor use. Normal operating ambient temperature should be within -20°F to +122°F (-29°C to +50°C). Operation of the remote condenser unit, for extended periods, outside of this normal temperature range may affect icemaker performance.

The remote condenser unit must be positioned in a permanent site under the following guidelines:

A firm and flat site.

A dry and well ventilated area with 24" (61 cm) clearance in both front and rear for proper air circulation and ease of maintenance and/or service should they be required.

The maximum line length for the standard refrigerant charge is 66 feet. Should an installation require a longer line length, line sizes must be increased and additional refrigerant must be added. Instead of the standard 3/8" OD discharge line and

1/4" OD liquid line for this icemaker, increase the line sizes to 1/2" OD discharge line and 3/8" OD liquid line for the entire run. Add 16.5 oz. of R-404A to the system to compensate for the larger diameter line sizes, then add .4 oz. of R-404A for each foot over 66 feet to a maximum of 100 feet. Hoshizaki Technical Support is available at 1800-233-1940 for recommendations.

The maximum vertical distance between the remote condenser unit and the icemaker is 33 feet above or 10 feet below the icemaker. These distances are measured fitting to fitting.
