6 PR O T EC T I O N — Once the units are properly positioned on the jobsite, they must be covered with either a shipping carton, vinyl film, or an equivalent protective covering. Open ends of pipes stored on the jobsite must be capped. This precaution is especially important in areas where painting, plastering, or spraying of fireproof material, [...]

7 4. Remove 4 bolts and take blower glides out. See Fig. 7. 5. Attach blower glides to blower bottom load brackets as shown in Fig. 8. Use bottom set of holes on blower bot- tom load brackets. The blower shaft should be sitting di- rectly on top of the blower glides. 6. Stand in front and pull the blower assembly on to the ridge of the blower glide[...]

Put belt back on and tighten. Put control box cover and motor cover on return side. See Fig. 22. 8. Put 3 panels back onto unit. See Fig. 23. Step 5 ?[...]

10 Each unit must be installed with its own individual trap, vent and means to flush or blow out the condensate drain line. Do not install units with a common trap or vent. See Fig. 25. Consider the following: • Units are typically installe d directly above each other on successive floors with condensat e drains located near the units. • Connec[...]

11 • Boiler drains and oth er valves should be connected using a “T” connector to allow acid flushing for the heat exchanger . • Do not overtighten connections. • Route piping to avoid serv ice access areas to unit. • Use PVC SCH80 or copper piping material. NOTE: PVC SCH40 should not be used due to system high pressure and temperature [...]
