It is essential that the sensors are correctly located to ensure efficient system performance.
The 3
rd
Party Dx-Coil should be supplied with a Gas Header and Liquid Capillary Distributor (see below).
Installer must procure the extension field wire compliant to NFPA/NEC for local cables to connect temperature sensor and to
connect the terminal block as necessary.
•Install the temperature sensor wire in an orientation such that gravity will not cause moisture to accumulate on the sensor
or penetrate the conductor insulation.
•Make a good connection between temperature sensor and Dx-coil. Put the top of the thermistors
on the Dx-Coil, this is the most sensitive point of the sensor.
1. Most sensitive part of the sensor
2. Maximize the contact with pipe
TC1 Sensor Ø4
(Small Sensor Holder).
Gas Header Pipe.
Avoid positioning Sensor
holders in the Drain Pan where
they could be immersed in
water.
TCJ Sensor Ø6
(Large Sensor Holder).
This should be brazed to the
capillary on the lowest circuit
(2inch ± 1inch from end plate).
TC2 Sensor Ø6
(Large Sensor Holder).
This should be brazed to the
pipe between PMV and
distributor.
