IMPORTANT PLUMBING TIPS
ALWAYS use a backup wrench when installing water fittings. Failure to do so can
cause damage to the copper lines, which is not covered under warranty.
ALWAYS use the brass strainer that is provided with the unit. The strainer must be
installed on the supply line water connection to prevent particles from entering
and damaging the heat exchanger. Clean the strainer regularly to maintain
optimum water flow.
Periodically check the strainer to verify that the chiller is receiving the desired
water flow. A decrease in flowrate could indicate a clogged filter. Isolate the flow
to the chiller before opening the wye strainer to inspect or service.
Monitor chiller flowrate using a properly sized rotameter or vortex (turbine – type)
flowmeter. Chiller flow should be within 25-75% of device full scale range.
Process fluid must be supplied to the chiller at a rate of 2.5 GPM per nominal
cooling ton. Improper flow can lead to permanent equipment damage and/or
reduced cooling performance.
The proper pump sizing depends on many factors and is critical to system
operation and reliability. Please contact Surna for more details on properly sizing
your pump.
