Page 13: Installation Steps
RC SERIES INSTALLATION MANUAL Installation Steps Step 1: Unpack Equipment and Inspect for Damage Step 2: Determine Equipment Location • Choose level flooring surface (Correctable with shims. Do not pitch towards drain.) • Location of wall support and fasteners required to secure chassis backplate. • Easy access for both installation and service. - Page 14 RC SERIES INSTALLATION MANUAL Installation Steps cont. Step 4: Provide Water and Condensate Drain Connections • A two-pipe reverse return piping configuration is recommended as it equalizes the piping circuit lengths and delivers even water flow to each unit. A direct return piping configuration may be used, but it may be difficult to achieve and maintain proper water flow to the units.
- Page 15 RC SERIES INSTALLATION MANUAL Installation Steps cont. Step 5: Provide Line Voltage Wiring • Check unit data plate located on control side of chassis for ampacity and fuse size. • Remove electrical knockouts from chassis backplate. • Run line voltage wiring through knockout and secure wiring to backplate or disconnect.

In this position controls will be on left end and piping on right end panel number 2 would be positioned against wall or back plate. -
Page 17: System Cleaning And Flushing
RC SERIES INSTALLATION MANUAL System Cleaning and Flushing Cleaning and Flushing Figure 7: Flushing with Water Prior to start up of any heat pump, the water circulating system must be cleaned and Shutoff Valve Equipped Systems flushed of all dirt and debris. Return Runout If the system is equipped with water shutoff valves, the supply and return runouts must be connected together at each unit location (This will prevent the introduction of dirt into the unit, see Figure 7). -
Page 18: Open Loop Ground Water Systems
RC SERIES INSTALLATION MANUAL Open Loop Ground Water Systems Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipita- tion. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in unit capacity data tables in the specification catalog. -
