Important
If the outside temperature is expected to fall below freezing (32°F) in the area the Multiaqua chiller is to be
installed; the installer must take the following precautions. Failure to do so will void the warranty.
To not engage in cold ambient mitigation will result in the failure of components such as the heat
exchanger, piping, circulating pump, etc... and or property damage.
• Keep the liquid solution at a minimum of ten percent propylene glycol even in areas where there is no danger
of freezing.
• The percentage amount of glycol recommended is dependent on the expected ambient temperatures and the
solution makeup recommendation of the glycol manufacturer. Refer to the Glycol Solution Data table above.
• Ensure the system circulating pump is in a constant energized mode to keep a continuous circulation of liquid
solution.
The Multiaqua chiller is a self-contained air-cooled condenser, coupled with an insulated brazed plate heat
exchanger (evaporator). The system utilizes a scroll compressor to circulate refrigerant between the condenser
and heat exchanger. The refrigerant is metered into the heat exchanger with a thermostatic expansion valve.
Protecting the system are high and low pressure switches as well as a pump flow switch.
Liquid solution (water and propylene glycol; minimum 10 % is required) is circulated through the heat
exchanger by an externally mounted pump. The liquid solution flows through the heat exchanger to the system
supply piping and on to the air handlers.
Low ambient kits are available for operating ambient temperatures down to -20 degrees Fahrenheit. The low
ambient kits consist of an ICM 325 (+) ICM (175) for single and three phase 208/230 vac chillers. For the three
phase 380/460 vac chillers a pressure activated fan control is used.
