Pre-Start Up PRE-START UP Before the chiller is started, there are certain essential checks which must be carried out. Failure to carry out these checks could result in damage to the chiller voiding the warranty. Electrical It is imperative to turn off the main electrical power supply and follow proper lock-out, tag-out procedures prior to servicing any of the chiller’s electrical components. The following procedures can be performed only after the electrical power is confirmed to be off: 1.
Start Up compressor has correct rotation. Use pressure gauges to verify proper rotation. Always use proper electrical safety precautions. 4. Slowly close the chiller water inlet isolating valve and note that the flow switch stops the machine. Note the flow rate at which this occurs. If too much flow is lost before chiller is stopped, reset switch setting.
Split System Start Up SECTION 3.0 - START-UP 3.1 General Once installation is complete, check the following: • • • • • All refrigerant and electrical connections must be tight. Tighten all loose wire terminal connections that may have loosened in shipping. The compressor oil is at the proper level in the oil sight glass (when provided) for the compressor being used. See “Compressor Oil Charge.” Check initial settings of thermostats and pressure controls.

Liquid Line Drier Core Replacement LIQUID LINE DRIER- INSTALLATION AND REPLACEMENT INSTRUCTIONS Replace any lost or damaged bolt and/or nut from a replaceable core Catch-All Filter-Drier. All bolts and nuts torqued to the proper value are required for proper safe fastening of the end plate and to prevent leakage. Bolts should be torqued to 14 to 16 ft-lbs on the C-480 Series Catch-Alls.
Refrigeration System Reprocessing REFRIGERATION SYSTEM REPROCESSING All ClimaCool remote air-cooled modular chillers leave the factory with both refrigeration circuits pressurized with 50 psig of dry nitrogen. These split system chillers require interconnecting refrigeration piping between the ClimaCool AR2 compressor/ evaporator module section and the remote condenser section. The condenser section provided by ClimaCool is typically a remote air-cooled condenser configuration.
Split System Interconnecting Piping Discharge Line Piping Recommendations All discharge lines should be kept as short as possible, and the line sizing is determined to provide for a low-pressure drop. There should always be a gradual negative elevation change when traversing from the remote condenser location to the AR2 module section. Avoid any reversing elevation changes throughout this discharge line run.
Refrigerant Charging Procedure Refrigerant Charging Once leak testing and evacuation are complete, refrigerant charging may commence. Always refer to the unit nameplate and the guidelines within this section in order to establish the quantity of refrigerant required. IMPORTANT: Always introduce refrigerant into a system using a charging manifold with gauges, along with a refrigerant scale to accurately weigh the refrigerant cylinder throughout the entire charging process.
Compressor Information COMPRESSOR INFORMATION The compressors used on the ClimaCool chiller are either scroll or reciprocating compressors. They are highly efficient and extremely reliable. However, the information contained in this document will be useful for their care. Compressor Rotation All scroll-type machines are unidirectional and will only compress in one direction.
Head Pressure Control Valve Operation ORI/ORD ORI VALVE OPERATION — The ORI head pressure control valve is an inlet pressure regulating valve and responds to changes in condensing pressure only. The valve designation stands for Opens on Rise of Inlet pressure. As shown in Figure-1, the outlet pressure is exerted on the underside of the bellows and on top of the seat disc.
Head Pressure Control Valve Operation ORI/ORD VALVE STRAINERS – Catch-All® filter-driers – See·All® moisture and liquid indicator — Just as with any refrigerant flow control device, the need for an inlet strainer is a function of system cleanliness and proper installation procedures. When the strainer is used with the ORI, the tubing is inserted in the valve connection until the tubing and strainer flange ring are up against the tubing stop, thus locking the strainer in place.
Head Pressure Control Valve Operation ORI/ORD The table below lists the setting data for the ORI and ORD valves. Other ORI settings can be obtained by adjusting the valves a proportionate amount between those values shown. 1 — COMPLETELY FLOODED CONDENSER: The easiest method is to calculate the volume of the condenser coil and then use the density factor of the refrigerant shown in Table-1 to figure the pounds of refrigerant necessary to completely flood the condenser coil at the appropriate ambient.
Head Pressure Control Valve Operation ORI/ORD EXAMPLE: Our example calls for a compressor equipped with unloaders. Since the compressor would unload at the low ambients this must be taken into consideration. This is necessary since as the compressor unloads, the condenser’s capacity increases and additional flooding is required. Using the same roof-top unit as in the earlier example (40°F evaporator and minus 20°F minimum ambient), a multiplier of .79 is shown in Table-2.
Head Pressure Control Valve Operation ORI/ORD REFRIGERANT CHARGING PROCEDURES — Normally this information is supplied by the equipment manufacturer. And when it is available, it should be followed. When it is not available from the equipment manufacturer, the following suggestions are recommended. Once the amount of extra refrigerant charge is calculated, care must be taken in charging the system to insure the proper total amount of refrigerant getting into the system.
