Dx-PMV kit
DX-PMV kit (RBM-A____1GUL) should be connected in liquid pipe line between outdoor unit and 3
rd
party coil. Please refer to
the installation manual of Dx-PMV kit.
NOTES
( Cautions when Brazing Dx-PMV kit )
A) Whilst brazing, PMV body and PMV head must be cooled to keep the component's temperature below 212°F.
B) Whilst brazing, nitrogen gas must be flowed through PMV valve and pipework to prevent internal oxidization.
C) Prevent cooling water from getting inside the PMV valve and connector of the lead during brazing.
D) Take care not to damage the PMV cables during brazing.
TA SENSOR
Secure this sensor using the supplied plastic clamp. It must be located before the DX-Coil after pre-
conditioning (Air to Air Heat exchanger / Return Air Mixing / Auxiliary Heating or Cooling). Ensure that
the Resin Sensor bulb is not covered by the protective vinyl-tube.
Installer must procure the extension field wire compliant to NFPA70/NEC for local cables to connect
temperature sensor and to connect the terminal block as necessary.

Avoid positioning Sensor
holders in the Drain Pan where
they could be immersed in
water.
