Page 2: Description Of The System
INTRODUCTION Description of the System The Mueller PAC Fre-Heater Model AL is designed to recover heat removed by refrigeration or air conditioning systems and to utilize that heat for heating water. It is a heat recovery system which heats and stores hot water all in one unit. - Page 3 When selecting a location for PAC Fre-Heater, the ability of that location to bear the loaded weight of the Fre-Heater should be a prime consideration. The loaded weights of all PAC Fre-Heaters are listed in Table 1.

Page 14: Section 2.0 - Installation
Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSIZ 2 1.22-1971, should be installed. The valve must be marked with a maximum set pressure of 150 psig for use on all PAC Fre-Heaters. PAC HEAT RECOVERY WATER HEATER... - Page 15 Fre-Heater. At those times a piping scheme should be used. This allows the Fre-Heater to operate at its optimum heat reclaim while the system temperature is at a higher level. Figure 14 : Installing Water Piping PAC HEAT RECOVERY WATER HEATER...

Page 17: Refrigeration Connections
If they are, particular care must be taken to avoid oil traps and excessive pressure drop in the lines. The refrigeration lines going to and from PAC Fre-Heaters could reach temperatures of 150°C. The refrigeration lines must be insulated to prevent a burn hazard for personal injury or combustible substances. - Page 18 PAC Fre-Heater units. To assure proper condensing unit operation, stay within the capacity range specified. A refrigeration unit exceeding the single circuit capacity of a specific PAC Fre-Heater may be connected to two or more Fre-Heater circuits on one or more Fre-Heaters having a combined circuit capacity equal to the...

Page 19: Refrigerant Charge
Fre-Heater becomes warm. Test Run Turn on the water supply and fill the Model PAC Fre-Heater with water. Ensure that all water and refrigeration connections are leak- free. The unit is then ready for use. Refrigerant charge should be checked after the system has achieved normal operating conditions. - Page 20 INSTALLATION AND OPERATION MANUAL Figure 17 : Installing Refrigerant Charge with Air-Condition Figure 18 : Typical Refrigeration Connections for Single Refrigeration Unit and Single-Circuit Piping PAC HEAT RECOVERY WATER HEATER...
