Installation
You can mount the ZIP Economizer in any orientation; it is recommended
that you mount it in a position that will allow full utilization of the LCD
and key pad and proper clearance for installation, servicing, wiring, and
removal.
Take the overall dimensions of 6.63" [168.5] x 7.12" [181] x 2" [50.8] and
mount in the interior of the RTU in a convenient location that you can
access. Secure the ZIP utilizing #8 self-tapping screws (included). A
minumum of two tabs need to be secured, one which is a top tab. Ideally
secure all four tabs. Wire the electrical connection using ¼” female
insulated spade connectors to prevent corrosion.

* The power consumption is for the control only and does not include connected loads
such as actuator, compressors, fans, and sensors. For transfomer sizing, the power
consumption of these attached components must be included.
** At low temperature the display has decreased response time. Below -22°F [-30°C] it will
not function.
