Installation Procedures
Step 2 - Mounting the AQUAVAR II controller:
AQUAVAR Controller
The AQUAVAR controller may be installed as a wall or panel mounted unit. The AQUAVAR controller may
be mounted up to 60 feet away from the pump motor*. In addition, alternative motor enclosures
may be selected such as ODP, explosion proof or wash down motors in addition to the TEFC enclo-
sure required for on the pump mounting.
Typical applications for the AQUAVAR Wall Mount controller include:
1. Hazardous environment applications including high heat, humidity or combustibility.
2. Installation to an existing pumping system with non-standard motors.
3. Installations where the operator desires all controls to be grouped together.
Mounting of the AQUAVAR II Controller
1. An alternative mounting style is used in the AQUAVAR II controller configuration.
In this style, the AQUAVAR II controller is supplied with a fan and mounting bracket already
installed and can be mounted to a wall or panel.
2. The mounting bolts for all units should be 1⁄4". The length of bolt and the strength of the
mounting surface must be adequate to support the weight of the AQUAVAR II controller.
3. The AQUAVAR II controller may be positioned up to 60 feet from the pump motor. The pump
motor must be three phase. Unlike the standard AQUAVAR controller, the motor may be
ODP, TEFC or explosion proof.*
4. Mount the AQUAVAR controller to the panel, wall or frame using bolts at the points indicated
on the following drawings. Be sure the unit is level and secured to the mounting surface
before continuing.
5. Ensure plenty of airflow for the AQUAVAR controller, when mounting.
*NOTE: If the AQUAVAR II controller is more than 60 feet wire length to motor, then the use of a
load reactor (impedance coil) is required.
