Technical Guide 6
Dimensions and Mounting
It is important to keep the module in a location that is free from extreme
high or low temperatures, moisture, dust, and dirt. Be careful not to
damage the electronic components.
Power Supply
The Dual Electronic Expansion Valve Module requires a 24 VAC power
connection with a minimum power rating of 1 VA.
WARNING: Observe polarity! All boards must be wired
GND-to-GND and 24 VAC-to-VAC. Failure to
observe polarity could result in damage to the
boards.
Environmental Requirements
The Dual Electronic Expansion Valve Module needs to be installed in
an environment that can maintain a temperature range between -30°F
and 150°F and not exceed 90% RH levels (non-condensing).
Mounting
The Dual Electronic Expansion Valve Module is housed in a plastic
enclosure. It is designed to be mounted by using the 3 mounting holes
in the enclosure base. It is important to mount the module in a location
that is free from extreme high or low temperatures, moisture, dust, and
dirt. Be careful not to damage the electronic components when mount-
ing the module.
