RW SERIES 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 loop 2.

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

ReplacementProcedures

description of the replacement parts required.
