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.
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.
8 12. Reattach blockoff air handler as shown in Fig . 15. 13. Put 3 panels back onto unit. See Fig. 16. Sound minimization is achieved by enclosing the unit with- in a small mechanical room or a closet. The following are addi- tional measures for sound control.
9 4. Loosen belt tension and take belt of f. See Fig. 20. 5. Remove bolt-belt adjustment assembly . See Fig. 20. 6. Move bolt-belt adjustment as sembly to opposite side and reattach. See Fig. 21. 7. Put belt back on and tighten. Put control box cover and motor cover on return side.
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.
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.
12 Table 2 — Water Quality Guideline s LEGEND *Heat e xchan ger materials co nsidered are copper , cupronic kel, 304 SS (stain - less stee l), 316 SS , titaniu m. †Closed recircul ating system is id entified by a closed pressu rized piping syst em.

33 FIELD SELECT ABLE INPUTS Jumpers and DIP (dual in-line package) switches on the control board are used to customize unit operation and can be configured in the field.
34 Auto Dehumidification Mod e or High Fan Mode — Switch 7 provides selection of auto dehu midification fan mode or high fan mode. In auto dehumidification fan mode the fan speed relay will remain off during cooling stage 2 if terminal H is active. In high fan mode, the fan enable and fan speed relays will turn on when terminal H is active.
35 Table 15 — 50VQP Unit Operating Limits LEGEND *Requires optional insulation package when operating below the dew point. †With antifreeze, optional e xtended range insulation and low tem- perature cutout jumper clipped for antifreeze . If the suction pressure does not drop and the dischar ge pressure does not rise to normal levels: 1.
36 Table 17 — Coaxial Water Pressure Drop NOTE: If air is purged from the system while using a 250 mm PVC fl ush tank, only a 2 5 to 50 mm level drop will be noticed since liquids are incompressible. If the level drops more than this, flushin g should continue since air is still being compressed in t he loop.
37 Units with Aquazone™ Complete C Contr ol ST ANDBY — Y and W terminals are not active in Standby mode, however the O and G terminals may be active, de- pending on the application. The compressor w ill be off. COOLING — Y and O terminal s are active in Cooling mode.
38 Table 20 — Complete C Control Current LED Status and Alarm Relay Oper ations LEGEND NO TES: 1. Slow flash is 1 flash e very 2 seconds. 2. F ast flash is 2 flashes every 1 second. 3. EXAMPLE: “Flashing Code 2” is represented b y 2 f ast flashes follo wed by a 10-second pause .
39 Retry Mode — In Retry mode, the st atus LED will start to flash slowly to signal that the control is trying to recover from an input fault. The control will stage of f the outputs and try to again satisfy the thermostat used to terminal Y . Once the ther- mostat input calls are satisfied, the control will continue normal operation.
40 Drain condenser and flush with clean water . Follow acid manufacturer ’ s instructions. Checkin g System Char ge — Units are shipped with full operating charge. If rechar ging is necessary: 1. Insert thermometer bulb in insulating rubber sleeve on liquid line near filter drier .
