RW SERIES REVERSIBLE CHILLER INSTALLATION MANUAL
Unit Heat Exchanger Maintenance
1.
Keep all air out of the water or antifreeze solution.
2.
Keep the system under pressure at all times. Closed 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.
Preventive Maintenance
