LOCATION AND LEVELING THE CHILLER A. Location Locate the falling film chiller as close as practical to the process and to the condensing units. A drain should be close by for draining the chiller. Consider ease of disassembly for cleaning and the possible future addition of more vertical evaporator plates when selecting a location for the falling film chiller. -

Chilled water line (see Table 2.13 for the recommended chilled water line size). • Adapter, tri-clamp to pipe thread. The 2" adapter is Mueller Part No. 9840758; the 2" is Part No. 9840759; the 4" is Part No. 9819684; and the 6" is Part No. 9841439. -
Page 14: Liquid Line Solenoid Valve
LIQUID LINE SOLENOID VALVE The Mueller condensing unit is designed to start and stop based on water temperature. It is not designed as a pump-down system. For proper operation of the falling film chiller it is necessary to install a liquid line solenoid valve to prevent refrigerant migration during down time. -

2.10 MUELLER MULTI-STAGE CHILLER COOLING AND PUMP CONTROL If a Mueller multi-stage chiller cooling and pump control was purchased, please reference the multi-stage chiller control manual for installation and setup procedures. A crucial step in the installation of the multi-stage chiller control is the location of the temperature sensors. A rise in water temperature inside the chiller’s distribution pan will turn on Stage 1 and the condensing unit. -
Page 16: Setting Chiller Recirculation Flow And Water Makeup Flow
The idea behind the falling film chiller is that when the chiller calls for makeup water, the sensor sees the rise in temperature as the water enters the pan. -
Page 17: Cleaning The System
IMPORTANT: In rare cases, it is possible for chlorine gas to escape from the water as it passes over the falling film chiller. If this occurs, red rust will begin to form inside the chiller on the areas that are not constantly wet. - Page 18 This cross flow of air will remove the gas from the interior of the chiller. If it is necessary to clean the chiller due to rusting, a #2 metal conditioner is recommended.
