REQUIRED CHANGES FOR COOLING UNITS AND
HEATPUMP UNITS
1. Crankcase heaters are required on all app lications where
low--ambient controls are used.
2. Start capacitor and relay (hard start) kits are required on all
single--phase applications wherelow--ambientcontrols are
used.
3. Evaporator freeze thermostat KAAFT0101AAA is
required on allapplications where low--ambientcontrols
areu sed.
4. Wind bafflesare required for temperaturesbelow 0_For
wherethere is substantialwind.
NOTE: When wind bafflesare used, raising unit offof pad a
minimum of 4 in. is required to provide better airflow for
moderate-- and high--ambient temperatures. Check pre--sale
literature for available support feetor unit risers.
CUTHAZARD
Failure to follow this caution could result in personal
injury.
Toreduce risk of personalinjury, wearpersonal protective
equipment when working with wind baffles. Only
experiencedtechnicians should fabricateand install wind
baffles.

!

CAUTION
5. For cooling applications only, winter start control
KAAWS0101AAA must be used where low--pressure
switchtripping may be encountered. Winterstart control
must be wired in parallel with low--pressure switch. This
allows a delay of 3 minu tes before low--pressure switch
becomes part of control circuit. (See Fig. 5 .)
