Page 18: Safety And Health
• Scroll Condensing Unit • JEHSCU Safety and Health Important Note Only a qualified refrigeration engineer who is familiar with refrigeration systems and components, including all controls should perform the installation and start-up of the system. To avoid potential injury, use care when working around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in accordance with all applicable codes, ordinances and local by-laws. -
Page 19: Installation & Commissioning
• Scroll Condensing Unit • JEHSCU Installation & Commissioning Unit site location • In order to achieve maximum cooling capacity, the installation location for condensing unit should be carefully selected. • Install the condensing unit in such a way so that hot air distributed by the condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). -
Page 20: Field Piping
• Scroll Condensing Unit • JEHSCU Installation & Commissioning Installation Clearance • The installation location should allow sufficient space for air flow and maintenance around the unit. • To allow sufficient space for doing service or installation. Field Piping Important Note Line sizing should only be determined by qualified personnel. - Page 21 • Scroll Condensing Unit • JEHSCU Installation & Commissioning Recommend compressor working pressure range Med Temp Low Temp Med Temp Compressor Model ZB*KQE ZF*KQE ZB*KQE Refrigerant R404A R404A R134A Working Pressure Range High 7.14 - 27.6 7.14 - 24.6 6.6 - 22.6 Side, (barg) Working Pressure Range Low...
- Page 22 • Scroll Condensing Unit • JEHSCU Installation & Commissioning Safety pressure switch settings The pressure switch fitted to condensing units with auto reset for low pressure and manual reset for high pressure are NOT factory preset. High pressure safety (Manual reset) The high pressure safety switch is required to stop the compressor, should the discharge pressure exceed the values shown in the following table.
- Page 23 • Scroll Condensing Unit • JEHSCU Installation & Commissioning Important Note There must be no more than 10 compressor starts per hour. A higher number reduces the service life of the compressor. If necessary, use an anti-short-cycle timer in the control circuit. Minimum a 3 minute runtime after each start of compressor and a 3 minute idle time after each stop are recommended.
