1 Important Safety Instructions The following symbols and labels are used throughout this manual to indicate immediate or potential safety hazards. It is the owner’s and installer’s responsibility to read and comply with all safety information and instructions accompanying these symbols. Failure to heed safety information increases the risk of personal injury, property damage, and/or product damage.
PAGE 3
2 Shipping Inspection Always transport the unit upright; laying the unit on its side or top during transit may cause equipment damage. The installer should inspect the product upon receipt for shipping damage and subsequent investigation is the responsibility of the carrier. The installer must verify the model number, specifications, electrical characteristics, and accessories are correct prior to installation.

for electrical wiring connections. Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area that may become wet (such as crawl spaces), elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage. Always install units such that a positive slope in condensate line (1/4" per foot) is allowed. 5.

tubing panel may remain screwed together during this procedure. Remove and retain the seven (7) screws securing the coil access panel to the cabinet and the six (6) screws securing the blower access panel to the cabinet. 2. Slide the coil assembly out using the drain pan to pull the assembly from the cabinet. NOTE: DO NOT USE MANIFOLDS OR FLOWRATOR TO PULL THE COIL ASSEMBLY OUT. FAILURE TO DO SO MAY RESULT IN BRAZE JOINT DAMAGE AND LEAKS. 3.

5. Re-install the center support (if removed) using the two (2) screws removed in Step 4. 6. Re-install the access panels removed in Step 1 as shown in Figure 9. 7. The bottom left drain connection is the primary drain for this application and condensate drain line must be attached to this drain connection. The top connection of the three drain connections on the drain pan must remain plugged for this application. The bottom left drain connection is for the secondary drain line (if used).

. Replace access panels, suction line grommet, insulation and all screws. 8 Condensate Drain Lines The coil drain pan has a primary and a secondary drain with 3/4" NPT female connections. The connectors required are 3/ 4" NPT male, either PVC or metal pipe, and should be hand tightened to a torque of no more than 37 in-lbs. to prevent damage to the drain pan connection. An insertion depth of approximately 3/8” to 1/2” (3-5 turns) should be expected at this torque. 1.

The return ductwork is to be connected to the air handler bottom (upflow configuration). 10 Return Air Filters Each installation must include a return air filter. This filtering may be performed at the air handler using the factory filter rails or externally such as a return air filter grille.

12 Electrical and Control Wiring IMPORTANT: All routing of electrical wiring must be made through provided electrical knockouts. Do not cut, puncture or alter the cabinet for electrical wiring. Nominal Input 208-240 Minimum Voltage 197 Maximum Voltage 253 ELECTRICAL VOLTAGE 12.1 Building Electrical Service Inspection Table 7 This unit is designed for single-phase electrical supply only. DO NOT OPERATE ON A THREEPHASE POWER SUPPLY. Measure the power supply to the unit.

12.4.1 Air Handler Only (Non-Heat Kit Models) The building supply connects to the stripped black and red wires contained in the air handler electrical compartment cavity. A ground screw is also contained in this area. Attach the Supply wires to the air handler conductors as shown in the unit wiring diagram using appropriately sized solderless connectors or other NEC or CEC approved means. 12.4.

Communication mode use TOP This feature can be activated or deactivated through the thermostat user menus. An auxiliary alarm switch must be normally closed and open when the base pan’s water level in the evaporator coil reaches a particular level. The control FRONT VIEW SIDE VIEW will respond by turning off the outdoor compressor and display the proper fault codes. If the switch is detected closed for 30 seconds, normal operation resumes and the error message will be removed.

17 Circulator Blower This air handler is equipped with a multi-speed circulator blower. This blower provides ease in adjusting blower speeds. The Specification Sheet applicable to your model provides an airflow table, showing the relationship between airflow (CFM) and external static pressure (E.S.P.), for the proper selection of heating and cooling speeds. The heating blower speed shipped is set at 21kW or 25kW, and the cooling blower speed is set at “D”.

If an electric heater kit has not been installed, set dip switches 9, 10, and 11 to any valid heater kit setting (see airflow table for valid settings). This will prevent an Ec Error code from being displayed. NOTE: For installations not indicated in the preceding Temperature Rise Tables, the following formula is to be used: TR = (kW x 3412) x (Voltage Correction) / (1.08 x CFM) Where: TR = Temperature Rise kW = Heater Kit Actual kW 3412 = Btu per kW Voltage Correction =.96 (230 Supply Volts) =.

.3 Fault Recall The integrated control module is equipped with a momentary push-button switch that can be used to display the last six faults on the 7 segment LED display. The control must be in Standby Mode (no thermostat inputs) to use the feature. Depress the push-button for approximately two seconds and less than five seconds. The LED display will then display the six most recent faults beginning with the most recent fault and decrementing to the least recent fault.

maximum airflow capability. If the thermostat provides four continuous fan speeds then a 100% airflow option is added. During continuous fan operation, the thermostat sends a fan request along with the continuous fan demand to the air handler. The air handler, in turn, sends the demand to the ECM motor. The ECM motor delivers the requested continuous fan airflow. 20.2 CTK0* Thermostat Wiring NOTE: Refer to section Electrical Connections for 208/230 volt line connections to the air handler.

SPLIT SYSTEMS AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer. Replace or Clean Filter IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire. An indoor air filter must be used with your comfort system.
