XVII. INDOOR AIR FLOW DATA
Belt-drive blower models have motor sheaves set for proper CFM at a typical external
static. See tables for blower performance.
XVIII. CRANKCASE HEAT (OPTIONAL)
Crankcase heat is not required on scroll type compressors, but may be necessary for
certain situations.
XIX. PRE-START CHECK
1. Is unit properly located and slightly slanted toward indoor condensate drain?
2. Is ductwork insulated, weatherproofed, with proper spacing to combustible materi-
als?
3. Is air free to travel to and from outdoor coil?
4. Is the wiring correct, tight, and according to unit wiring diagram?
5. Is unit grounded?
6. Are field supplied air filters in place and clean?
7. Do the outdoor fan and indoor blower turn freely without rubbing, and are they tight
on the motor shafts?
XX. STARTUP
1. Turn thermostat to "OFF," turn "on" power supply at disconnect switch.
2. Turn temperature setting as high as it will go.
3. Turn fan switch to "ON."
4. Indoor blower should run. Be sure it is running in the right direction.
5. Turn fan switch to "AUTO." Turn system switch to "COOL" and turn temperature
setting below room temperature. Unit should run in cooling mode.
6. Is outdoor fan operating correctly in the right direction?
7. Is compressor running correctly.
8. Check the refrigerant charge using the instructions located on compressor access
panel. Replace service port caps. Service port cores are for system access only
and will leak if not tightly capped.
9. Turn thermostat system switch to proper mode "HEAT" or "COOL" and set thermo-
stat to proper temperature setting. Record the following after the unit has run some
time.
A. Operating Mode _______________________________
B. Discharge Pressure (High) ___________________PSIG
C. Vapor Pressure at Compressor (Low) __________PSIG
D. Vapor Line Temperature at Compressor___________°F.
E. Indoor Dry Bulb______________________________°F.
F. Indoor Wet Bulb _____________________________°F.
G. Outdoor Dry Bulb ____________________________°F.
H. Outdoor Wet Bulb ____________________________°F.
I. Voltage at Contactor ________________________Volts
J. Current at Contactor _______________________Amps
K. Model Number_________________________________
L. Serial Number _________________________________
M.Location______________________________________
N. Owner _______________________________________
O. Date_________________________________________
10. Adjust discharge air grilles and balance system.
11. Check ducts for condensation and air leaks.
12. Check unit for tubing and sheet metal rattles.
13. Instruct the owner on operation and maintenance.
14. Leave "INSTALLATION" and "USE AND CARE" instructions with owner.
