All heater kit temperature rise data in
Table 4
was calculated
using 10kW heaters (9kW for 3 phase units). For other sized
heater kits, use the following steps below to determine the
heat rise for your particular heater kit.
1. Determine your CFM.
note:
Find this data by locating
your blower motor tap settings in the data supplied with
the Installation Instructions.
2. Locate your heater kits kW value and Btu/h in Table 5
(page 11) .
3. Input the values into the following equation:
Temp Rise: ΔT= (Btu/h)/(CFM*1.08)
note: Generally the heat rise should be 30 - 40 degrees.
Anything above 40 degrees should be avoided.
blower Speed
caution:
to avoid personal injury or property damage,
make certain that the motor leads cannot
come into contact with any uninsulated metal
components of the unit.
The blower speed is preset at the factory for operation at
the same speed for heating and cooling. Factory settings
are listed in
Table 4 . For optimum system performance and
comfort, it may be necessary to change the factory set speed.
