Use the provided gasket inside the rooftop Mount and use the delivered lifting device unit and fix it to the ERM internal edge as for ERM handling as shown in Figure 2.
- Page 5 Installation The ERM needs to be supported on the perimeter panels. The frame surface should be flat and perfectly aligned with the rooftop bottom plan. Position the ERM so that it is aligned with the down left corner of the rooftop. See Figure 3. Figure 3 - Fasten the ERM with the flat / back side flange (1) to ensure the ERM is perfectly aligned with the rooftop.
- Page 6 Installation Fasten the roof end to the ERM with self-drilling screws as shown in Figure 5. Figure 5a - Figure 5b - Run all the ERM cable (power and actuator) and transparent hose (if installed) into the rooftop fresh air / filter section. Place the fresh air filter into the filter rack located behind the fresh air inlet louver of the ERM.

Installation Exhaust / Return fan cable Figure 7 - connection Run the power exhaust fan motor power cables to the speed inverter. Connect the three phases and ground cable(s) to the MOTOR terminal of the speed inverter. Respect the cable numbers as shown in Figure 7. - Page 9 Installation On unit sizes 125-155-175-200-250- 265-290-340, the return air sensor of the economizer needs to be placed into to return air section of the ERM. Place return air temperature sensors in the air return section of the ERM as indicated in Figure 9.

Page 10: Service Test Guide For Component Operation
Operation Service Test Guide for Component Operation Test and setup of the ERM is performed during the first two steps of the rooftop test sequence. Step 1 of the test simulates normal ventilation mode of the unit. Step 2 of the test simulates free cooling mode. During step 1, adjust the return air damper position by turning the minimum position potentiometer on the Economizer module (ECA). - Page 11 Operation Figure 10b - Air circulation in normal operation 125-155-175-200-250-265-290-340 125-155-175-200-250-265-290-340 Min% Min% Min% Min% Min% 100% Min% M M M M i i i 100-Min% 100% Min% Min% Min% 100% 100% 100% 275-300-350-400-500-600 275-300-350-400-500-600 open 100% Min% Min% Min% Min% Min% 100-Min%...

Page 14: Defrost Pressure Switch (Phe Version)
Operation Defrost pressure switch (PHE version) In winter mode, frost occurs in the return air side of the exchanger increasing pressure drop. The defrost pressure switch setting should be setup so that it does not switch in free cooling mode (100% exhaust air flow). During the free cooling test mode, adjust the pressure switch setting to reach the threshold point. -
