RPM and motor amperage and voltage <br />recorded. <br />Gas Piping System: Piping shall be tested with air at 50 <br />pslg for a period of two hours. Soap test all joints. Use^ <br />clean dry air for testing. The systems which may be contamln <br />ated by gas shall be purged before testing. <br />D. Automatic Temperature Control <br />All temperature control systems shall be checked out <br />under operating conditions with the actual operations <br />verified and temperature reading around each control <br />point to prove the correct control function or operation <br />All damper functions shall be similarly verified. These <br />facts shall also be included with the certificates. <br />E. Automatic Temperature Control (Electrical) <br />1.Test the systems to maintain the required conditions. <br />The system must perform the functions Indicated while <br />operating in the sequences specified. <br />F. Ventilation Tests <br />1. <br />2. <br />Terminal Devices: Upon completion of the work and prior <br />to final inspection, all ventilating equipment shall <br />be placed in operation and adjustments made as necessary <br />in fan speeds and damper settings to provide air quanti­ <br />ties shall be provided. Velocity readings taken at all <br />supply, return, exhaust and fresh air grilles, registers, <br />Ipuvers and hoods with alnor, anemotherm or equal instru­ <br />ment as approved by the Owner/Engineer. Not less than <br />four readings shall be taken at each device and the cor­ <br />responding air volume computed. Submit copy of test <br />results to the Owner/Engineer for review. <br />Fans and Motors: Test under load conditions with static <br />pressures at fan Inlet and outlet, fan RPM and motor <br />amperage and voltage recorded. <br />15020-2 <br />5 d <br />•t
