Unit Commissioning and Operating Conditions
Table 9: Water Temperature Change Through
Heat Exchanger
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, airfl ow, water temperature,
water fl ow rate and ambient air temperature. This water
to air heat pump is capable of operating over a wide
temperature range and with fl ow 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.

Table 8: Building Commissioning
Table 8A: Unit Operating Limits
The commissioning table indicates air and water
temperatures which are suitable for initial unit
commissioning in an environment where the fl ow 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.

product catalog, the submittal data sheets or contact
your supplier for assistance.
