- Page 13 Unit operation procedure is identical as RTAC Chiller (Refer to RTAC IOM ref RLC-SVX02) Control System The unit capacity control is identical as for the chiller version. Water temperature values have to be interpreted as evaporator air temperatures,especially through BAS data point list interpretation: Entering water temperature is replaced by evaporator entering air dry bulb temperature.
- Page 14 The following maintenance instructions are part of maintenance operations required for this equipment. A qualified technician is needed for regular maintenance as part of a regular maintenance contract. Carry out all operations as required by schedule. This will insure long unit service life and reduce the possibility of serious and costly breakdown.
