Standard Unit Features - Daikin RCS Series Installation And Maintenance Manual

Standard Unit Features

Cabinet — Galvanized steel with a durable powder paint
finish. Stamped louvered panels offer 100% protection for the
condenser coil.
Compressor — Hermetically sealed scroll compressors.
Compressors are mounted on rubber-in-shear pads to reduce
vibration and noise.
Condenser Coil — Constructed with copper tubes and
aluminum fins mechanically bonded to the tubes for maximum
heat transfer capabilities. All coil assemblies are leak tested at
450 psig internal pressure.
Refrigerant Connections — Field piping connections are made
through a fixed panel. This allows complete access or removal of
access panels after piping connections have been made.
Crankcase Heater — Standard, all models.
Low Ambient Control — A pressure sensitive fan cycling
control to allow unit operation to 0°F is standard.
Service Valves — Standard on liquid lines and vapor lines.

Service Access — The control box, as well as the compressor
and other refrigerant controls, is accessible through access
panels. It may be opened without affecting the normal
operation of the unit. Condenser fan motors are accessible by
removing wire grilles.
Filter Drier — Field supplied.
Sight Glass — Optional, field supplied.
Transformer — Step down type, line to 24 volts.
Contactor — The contactor is an electrical switch which
operates the compressor and condenser fans.
High Pressure Control — Opens the contactor circuit on high
refrigerant pressure; manual reset.
Low Pressure Control — Stops compressor operation in the
event of loss of refrigerant.
Condenser Fan Motor (Direct Drive) — Ball bearing 1075
RPM motors are mounted to minimize vibration and noise
problems.These are permanent split capacitor types and
require the same capacitance for both run and start.
Testing — All units are run tested at the factory prior to shipment.
Units are shipped with a holding pressure of nitrogen.
