S1C/S1H Single-Zone & S2C Dual-Zone Condensing Units installation, operation and maintenance MANUAL This manual is intended as an aid to a qualified service personnel for proper installation, operation, and maintenance of EMI AmericaSeries high efficiency condensing units. Carefully read these instructions before attempting installation or operation.
CONTROLS and COMPONENTS (Factory installed or supplied) PRODUCT DESCRIPTION The AmericaSeries S1C/H and S2C condensing units are, air-cooled, vertically arranged side discharge, high efficiency units designed specifically to meet or exceed a 13 SEER rating. The S1C 9,000-36,000 Btuh and S1H 9,000-24,000 Btuh capacity condensing unit will provide cooling for a single evaporator, as identified in the "S1C Specifications and Dimensions" section on pages 23-24.
Installation Instructions System OPTIOns (cont.) void the warranty. A Field installed lowambient kit is good for operation down to 32º F. This is accomplished by cycling the condenser fan on and off, which will in turn maintain a constant low side pressure providing a steady cooling effect and keeping the air handler from frosting-up. Unit Mounting Instructions S1C is shown Side discharge unit allows for permanent mounting through the feet.

Installation Instructions P-Trap Installation ricated trap may be purchased from a wholesaler or distributor however the trap should be shallow as the (3) elbow configuration. Each elbow is approximately 2 equivalent feet. One P-trap is equal to approximately 12 equivalent feet. • A P-trap is recommended when the suction riser is equal to or greater than 20 feet in height. • When the condenser is installed above the evaporator, the P-trap will help the return of oil back to the compressor.

Preperation for Start-Up • Remove gauge set. Mount all access panels and make sure they are properly secured. • Make final visual inspection and repair any deficiencies. STARTING THE UNIT • In low ambient cooling 9-12 Btuh units, if a crankcase heater is installed, power the system 24 hours before attempting to start the unit in cool weather (below 60° F). • After doing a final system check using the Operation Charts (supplied on previous pages). Record results on Test Unit Data Sheet on page 26.
Single-Zone and Dual-Zone Sequence of Operation (R & Y) will energize. When the indoor control is satisfied and the room temperature rises above the set temperature, the compressor and fan will de-energize. The anti-short cycle timer (ASCT) will prevent the compressor from re-starting for three minutes. Note: For remote wall mounted thermostat operation be sure to select EMI p/n 240004180 or a suitable 24v, two sage heating, heat pump thermostat.
Single-Zone and Dual-Zone Sequence of Operation Testing Defrost Operation using test pins The condenser will operate in heating for approximately 20 seconds. At that point the unit will enter defrost mode for approximately 2 seconds. During this time the condenser fan will switch off, the reversing valve will energize and the defrost board will energize the indoor electric heat relay through the “W” terminal.
