Page 14: Installation & Startup
(specify the extent and type of damage found). Unit should be inspected carefully for concealed damage. Notify Emerson sales/application personnel of the damage immediately. Request an immediate joint inspection and do not repair the unit until inspected by Emerson’s representative. - Page 15 c. Refrigeration Piping Installation All interconnecting pipes should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation. Even during installation, if the system is left for any reasonable period (say two hours), pipes should be re- capped to prevent moisture and contaminants from entering the system.
- Page 16 e. Electrical All electrical work must be done in accordance with the National Electrical Code and existing local codes. Power supply must be the same as specified on the unit’s name plate. Voltage fluctuations in excess of 10 percent must be corrected. Before starting the unit, ensure that all protective devices are in place and that all wiring is secure.
- Page 17 g. Start-up & Operation Initial pressure test (by vacuum and nitrogen) - Step-by-step: Use a 4-port gauge manifold with 3/8” hose and connections to the vacuum pump. The vacuum gauge does not have to be connected for this part of the process.
- Page 18 Ensure that all service valves are open during the leak test process. It is important to recheck all joints within the unit as well as the external joints. The unit is shipped with a holding charge of dry nitrogen and should be leak free.
- Page 19 Step-by-step: Ensure that there is no power supply to the H-Series unit. The Liquid Line solenoid needs to be kept open for the charging process and this may require a temporary power feed to it. Connect the refrigerant cylinder to main service hose and purge line at the manifold end.
