Unit Commissioning & Operating Conditions
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 water temperatures, water flow rates and ambient
air temperature. This water to water 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 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.
