Unit Commissioning & Operating Conditions
Environment – This unit is designed for indoor
installation only. Do not install in an area subject to
freezing or where humidity levels can cause cabinet
condensation.
Power Supply – A voltage variation of +/- 10% of
nameplate utilization voltage is acceptable.
Operation and performance is primarily dependent
upon return air temperature, airflow, water temperature,
water flow rate and ambient air temperature. This water
to air heat pump is capable of operating over a wide
temperature range and with flow rates of between 1.5
GPM (.1 l/s) and 3 GPM (.19 l/s) per ton, however usually
no more than one of these factors may be at a minimum
or maximum level at a time.

The commissioning table indicates air and water
temperatures which are suitable for initial unit
commissioning in an environment where the flow rate and
water temperature is not yet stable and to avoid nuisance
shut down of the units freeze and refrigerant pressure
safeties.
The operating table indicates the maximum and
minimum ranges of the unit.
For more specific unit performance reference the product
catalog, the submittal data sheets or contact your
supplier for assistance.
