Suction Pressure (see Figure 1)
1. Install the suction adapter fitting (Item 7) into the compressor’s low side port (torque
to 10-12 ft. lb, 14-16 NM).
2. Install the cross fitting (Item 8) into the adapter fitting (torque to 20-25 ft lb, 27-34
NM) using Teflon tape or pipe dope. The cross fitting can be oriented as desired.
3. The suction pressure transducer and low pressure switch are connected to the cross
fitting. The schraeder port is available for field gauge connections.
The
suction
pressure transducer (Item 2) can be identified by a
blue dot
located on
the black base of the transducer. The oil pressure and discharge pressure
transducers (Item 3) do not contain any special markings on the black base.
Discharge Pressure (see Figure 1)
1. Install the discharge adapter fitting (Item 6) into the compressor’s high side port.
2. Install the cross fitting (Item 8) into the adapter fitting (torque to 20-25 ft lb, 27-34
NM) using Teflon tape or pipe dope. The cross fitting can be oriented as desired.
3. The discharge pressure transducer
1
(has no color dot identifier) and high pressure
switch are connected to the cross fitting. The schraeder port is available for field
gauge connections.
