Note: The CVM uses a digital pressure sensor with bidirectional flow operation, which
allows you to connect the high- and low-pressure DP tubes to either barbed fitting on the
CVM controller. You do not need to make a specific high- or low-side connection when you
attach the tubing to the barbed fittings on the CVM.
10. Push the Manual Override button, and turn the actuator coupling manually to ensure that the
actuator can rotate from full-closed to full-open positions without binding.
11. Complete the mounting by rotating the damper to the full-open position.
CAUTION
Risk of Property Damage.
Rotate the damper to the full-open position before starting the air handler. Failure to rotate the damper
to the full-open position may result in damage to the VAV box or ductwork when the air handler is
started.
ATTENTION
Risque de dégâts matériels.
Faire pivoter le registre pour le placer en position d'ouverture complète avant de démarrer l'unité de
traitement d'air. Le non-respect de cette directive risque d'endommager le caisson de l'unité à volume
d'air variable (VAV) ou le réseau de conduites au démarrage de l'unité de traitement d'air.
