Carrier 06E - Manual (Page 4)

REFRIGERANT CHARGING
Evacuate, Dehydrate and Leak Test the entire
refrigerant system by methods described in Carrier
Standard Service Techniques Manual, Chapter 1,
Sections 1-6 and 1-7. Use sight glass method to
charge system. See Section 1-8 of Service Tech­
niques Manual for details.
CHARGE THE SYSTEM to a clear sight glass while
holding saturated condensing pressure constant at
125 F (air-cooled systems) or 105 F (water-cooled
systems) Add additional refrigerant to fill con­
denser subcooler coils.
07E Condensing Units - After clear sight glass is
obtained, add charge until liquid refrigerant
reaches condenser liquid level test cock.
06E Compressor Units — See condenser data for
additional charge required to fill subcooler.
All Units — Stamp type of refrigerant and amount
of charge on unit informative plate
INITIAL START-UP
Crankcase heater should be energized a mini­
mum of 24 hours before starting unit.
Check to see that oil level is approximately 1/3
up on the compressor sight glass.
Open water supply valve and allow water to
reach condenser. (Turn condenser fan on when the
compressor unit is applied with air-cooled con­
denser.)
Backseat the compressor suction and discharge
shutoff valves, open liquid line valve at receiver.
Start evaporator fan or chilled water pump.
Start Compressor — Push the control circuit
START-STOP-RESET switch to “Start.” The timer
motor starts immediately. Depending on the posi­
tion of the timer, the compressor start is delayed
for 12 seconds to approximately 8 minutes. Check
oil pressure after compressor has run a few
minutes, the pressure should be 12—18 psi above
the suction pressure After about 20 minutes of
operation, stop the compressor. Allow it to be idle
for about 5 minutes, then observe the oil level in
the sight glass. If the oil level is below the bottom
of the sight glass, refer to the Carrier Standard
Service Techniques Manual, Chapter 1, Section
1-11, for adding oil. The proper oil level for the
06E compressor is approximately 1/3 up on sight
glass.
