Note 1. Ensure no water or debris can enter the unit through any gaps around
wiring or piping.
2. Ensure adequate service space is right around the unit, according to Fig A.
3. Please always make water circulate or add the brine to the circulation water
when the ambient temperature becomes 0degC(32°F )or less.
4. The unit is not designed for outside installations.
5. Install the unit in an environment where the wet bulb Temp.
will not exceed 32degC(90°F).
6. The water circuit must use the closed circuit.
7. Please don't use the steel material for the water piping material.
8. Connect the strainer which is put as accessory to water inlet pipe.

<HIGH VOLTAGE WARNING>
· Control box houses high-voltage parts.
Before inspecting the inside of the control box, turn off the power,
keep the unit off for at least 10 minutes, and confirm that the voltage
CN631 on Control Board has dropped to DC20V or less.
<CAUTION FOR INSTALLATION>
· Prior to installation, read the Installation Manual carefully.
*1. Single-dotted lines indicate wiring not supplied with the unit.
*2. Dot-dash lines indicate the control box boundaries.
*3. Faston terminals have a locking function.
Make sure the terminals are securely locked in place after insertion.
Press the tab on the terminals to removed them.
