Installation

Condensate management problems such as water blow off could be the result of too great of air 
face velocity across the coil. To ensure proper operation refer to fan belt adjustment procedures, 

p. 51

.

SZVAV Units

For SZVAV units, air flow is set by using potentiometer R-136 on the ReliaTel options module (see 

Figure 17

 found in the air handler control box. The potentiometer will adjust the maximum air flow 

between the range of 60 Hz to 44.50 Hz. If the desired maximum operating point from the catalog 
fan table is lower than 44.50 Hz, parameter 6-15 on the VFD must be reprogrammed to 50 Hz. The 
VFD is preset from the factory to a default of 25 Hz for the lower limit and does not need to be 
reprogrammed.

Measure the voltage between TP1 on the RTOM and ground. Use 

Table 14, p. 39

 to set the desired 

maximum operating supply fan speed.
