Positioning Corayvac Modulating Heating Control - Roberts Gorden CORAYVAC Installation Manual

3.2 Positioning CORAYVAC
Control
3.2.1 For serviceability, it is convenient to mount the
controller at occupant level in the vicinity of the
pump. For proper frequency between the VFD and
pump, the wire length between controller and vac-
uum pump should not be more than 100' (30 m). A
Load Reactor (P/N 100610XX) will be required for
distances greater than 100' (30 m). Maximum dis-
tance with Load Reactor is 400' (120 m). Load reac-
tor should be mounted as close to VFD as possible.
Consult factory if distance required is greater.
Do not mount controller outdoors. Controller must
not be installed where subjected to adverse condi-
tions such as: combustible, oily, or hazardous vapors
or dust; excessive moisture or dirt; vibration. To avoid
damage from possible condensation leaks, do not
mount controller directly beneath pump. Avoid install-
ing the controller in mezzanines, direct sunlight, or
near external heat sources because these locations
usually have unpredictable temperature rises.
