Page 5: Foreword
We trust your equipment will have a long and useful Foreword life. If you should have any questions, please contact our Customer Service Department specifying the The portable chiller is a packaged unit typically serial number and model number of the unit as consisting of a refrigeration circuit, coolant reservoir, indicated on the nameplate. -
Page 6: Pre-Installation
Only qualified personnel should install, start-up, and Pre-Installation service this equipment. When working on this equipment, observe precautions in this manual as Receiving Inspection well as tags, stickers, and labels on the equipment. When the unit arrives, verify the information on the unit nameplate agrees with the order WARNING: Any use or misuse of this equipment acknowledgement and shipping papers. -
Page 7: Unit Storage
Chillers with an integral water-cooled or air-cooled Proper ventilation is another important condenser ship with a full refrigerant charge. Chillers consideration when locating the chiller. In general, designed for use with a remote air-cooled condenser locate the unit in an area that will not rise above and the remote condensers themselves ship with a 110°F. -

piping is overhead with a total run length over 90 Each condenser has a two-way condenser water- feet there should be a valve in the supply line and an regulating valve. The condenser water-regulating inverted P trap with a vacuum break valve installed valve controls the amount of water allowed to pass as shown in Figure 1. -

Avoid areas that can create a “micro-climate” such as The discharge and liquid lines leaving the chiller an alcove with east, north, and west walls that can be have caps. These line sizes do not necessarily reflect significantly warmer than surrounding areas. The the actual line sizes required for the piping between condenser needs to have unrestricted airways so it the chiller and the air-cooled condenser. - Page 10 General design considerations are: Figure 3 – Condenser Located at Chiller Level 1. The total distance between the chiller and the air-cooled condenser must not exceed 200 actual feet or 300 equivalent feet. Keep the distance as short as possible. 2.

Page 14: Standard Controller Operation
The chiller includes a controller to perform all Standard Controller Operation control functions directly from the front panel. When Control Power is applied, the controller initiates a diagnostic test of each indicating light and display segment by briefly lighting each sequentially. As part of this initial diagnostic test, the revision level of the control program displays for a moment. - Page 15 Table 7 - Operating Buttons Button Description of Operation Power Depressing the Power button switches the control power on or off. The control power must be on before the Start button or remote on/off contact can start the chiller. The light above this button is one when the power is on. Start Depressing the Start button starts the pump and enables the compressor.
