NXW REVERSIBLE CHILLER INSTALLATION MANUAL
Unit Heat Exchanger Maintenance
Keep all air out of the water or antifreeze solution.
1.
Keep the system under pressure at all times. Closed
2.
loop systems must have positive static pressure or air
vents may draw air into the system.
NOTES:
If the installation is in an area with a known high
mineral content in the water, it is best to establish with
the owner a periodic maintenance schedule for checking
the water-to-refrigerant heat exchanger on a regular
basis. Should periodic cleaning be necessary, use standard
cleaning procedures. Generally, the more water flowing
through the unit, the less chance there is for scaling. Low
GPM flow rates produce higher temperatures through the
heat exchanger. To avoid excessive pressure drop and the
possibility of metal erosion, do not exceed GPM flow rate as
shown on the specification sheets for each unit.
