PRESSURE TRANSDUCER INSTALLATION
For transducer information, refer to the DSV IOM manu-
al (145.29-IOM3) or DSH IOM manual (145.32-IOM5).
1. Mount the compact P499 or P599 transducer di-
rectly to the liquid refrigerant pressure port. This
port is incorporated into the refrigerant shutoff
valve (as illustrated with DSH single stage units
in Figure 4 on page 10).
On dual compressor units, the transducer
MUST be connected to the rst stage cir-
cuit liquid line tting. Connection to the
second stage refrigerant circuit can result
in system malfunction.
2. Hand thread the transducer onto the pressure port.
Wear gloves for protection. Seat the trans-
ducer as quickly as possible to minimize
release of liquid refrigerant.
3. To avoid damaging the transducer, tighten the
connection using the wrench ats provided
4. The connecting harness for the pressure trans-
ducer is pre-wired to the pressure control panel.
The sensor end of the harness is equipped with a
polarized plug connection. Insert the plug into the
end of the transducer and ensure that the locking
tab on the plug is engaged.
5. Perform a leak test on the refrigerant port connec-
tion before putting the system into operation.
