2 © 2004, Heatcraft Refrigeration Products LLC General Safety Information 1. Installation and maintenance to be performed only by qualified personnel who are familiar with this type of equipment. 2. Some units are pressurized with dry air or inert gas.
3 The most important consideration which must be taken into account when deciding upon the location of air-cooled equipment is the provision for a supply of ambient air to the condenser , and removal of heated air from the condensing unit or remote condenser area.
4 Figure 2. Solid Mount for Mobile or Deep Sump Application. Condensing Unit Rigging and Mounting Rigging holes are provided on all units. Caution should be exercised when moving these units. T o prevent damage to the unit housing during rigging, cables or chains used must be held apart by spacer bars.
5 Suction Filters, Driers, Sight Glasses There are two types of suction and liquid filter/driers used on Heatcraft Refrigeration Products units. Replaceable core and/or sealed units are used, dependent upon the option package ordered.
6 Mineral Oils The BR and Scroll compressors use Sontex 200, a “white oil”. This oil is not suitable for low temperature applications nor is it available through the normal refrigeration wholesalers.
7 Phase Loss Monitor The combination phase sequence and loss monitor relay protects the system against phase loss (single phasing), phase reversal (improper sequence) and low voltage (brownout). When phase sequence is correct and full line voltage is present on all three phases, the relay is energized as the normal condition indicator light glows.
8 Liquid Lines Liquid lines should be sized for a minimum pressure drop to prevent “flashing”. Flashing in the liquid lines would create additional pressure drop and poor expansion valve operation.

1 1 Line Insulation After the final leak test, refrigerant lines exposed to high ambient conditions should be insulated to reduce heat pickup and prevent the formation of flash gas in the liquid lines. Suction lines should be insulated with 3/4" wall Armstrong “Armaflex” or equal.
12 Field Wiring W ARNING: All wiring must be done in accordance with applicable codes and local ordinances. The field wiring should enter the areas as provided on the unit. The wiring diagram for each unit is located on the inside of the electrical panel door .
13 NOTE: All adjustable controls and valves must be field adjusted to meet desired operation. There are no factory preset controls or valve adjustments. System Balancing - Compressor Superheat IMPORT ANT : In order to obtain the maximum capacity from a system, and to ensure trouble- free operation, it is necessary to balance each and every system.
14 T able 7. System T roubleshooting Chart PROBLEM POSSIBLE CAUSES POSSIBLE CORRECTIVE STEPS Compressor will not run 1. Main switch open. 1. Close switch. 2. Fuse blown. 2. Check electrical circuits and motor winding for shorts or grounds. Investigate for possible overloading.
15 Preventive Maintenance Air Cooled Condensing Units Quarterly 1) Visually inspect unit • Look for signs of oil stains on interconnection piping and condenser coil. Pay close attention to areas around solder joints, building penetrations and pipe clamps.
