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.

2 Shipping Inspection 5 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.

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).

.3 Tubing Connections for TXV Models 3. Check subcooling and superheat. Systems with TXV application should have a subcooling of 7 to 9°F and superheat of 7 to 9°F TXV models come with factory installed TXV with the bulb pre-installed on the vapor tube. a. If subcooling and superheat are low, adjust TXV to 7 to 9°F, and then check subcooling. NOTE: To adjust superheat, turn the valve stem clockwise to increase and counter clockwise to decrease. b.

Ductwork This air handler is designed for a complete supply and return ductwork system. To ensure correct system performance, the ductwork is to be sized to accommodate 350-450 CFM per ton of cooling with the static pressure not to exceed 0.5" in w.c. Refer to ACCA Manual D, Manual S and Manual RS for information on duct sizing and application. Flame retardant ductwork is to be used and sealed to the unit in a manner that will prevent leakage.
PAGE 10
NOTE: The Temperature Rise Tables can also be used to estimate the air handler airflow delivery. When using these tables for this purpose set the room thermostat to maximum heat and allow the system to reach steady state conditions. Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the return air temperature. Using the temperature rise calculated, CFM can be estimated from the TR formula above.

13.4.1 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. 13.4.
PAGE 12
16.2 Electric Heater Kit Testing 16 Quick Start Guide for Communicating Outdoor Units EXTREMELY IMPORTANT: For all cooling calls the system only requires a single Y input from the thermostat. For all heating calls (including applications with backup electric heater kits) the system only requires a single W input from the thermostat. Internal algorithms will control all available cooling and heating stages based on these inputs. Any single-stage 24VAC thermostat can be used.
PAGE 13
4. Go to the Tonnage Units Menu () and select the tonnage value that corresponds to the desired airflow for the outdoor unit. See the following table. NOTE: For the two stage non-communicating outdoor units, system will stage airflow automatically for low stage operation. Figure 19 NOTE: The system will not provide airflows above the max Airflow Value. Figure 20 2. Download the Cool Cloud HVAC phone application.
PAGE 14
17.2 Electric Heater Kit Testing 1. Select the electric heat icon after entering the air handler menus while using the Cool Cloud phone application. 2. Select any value less than 50% for low stage operation and any value greater than 50% for high stage operation. 3. Confirm thermostat heating and cooling calls function properly for high stage operation. enter into a main menu and to then permanently select options within those menus.

22 Ramping Profiles 23 Electric Air Cleaner Warning The variable-speed circulator offers four different ramping profiles. These profiles may be used to enhance cooling performance and increase comfort level. Select the desired ramping profile using the Cool Cloud phone application or the push button menus. The control is equipped with an Accessory Relay and a pair of ¼ inch accessory terminals which is normally open, labeled EAC-IN and EAC-OUT (see accessory contacts graphic).
PAGE 16
24 Start-Up Procedure • Prior to start-up, ensure that all electrical connections are properly sized and tightened. • All panels must be in place and secured. For Air Tight application, neoprene gasket must be positioned at prescribed locations to achieve low airflow as stated in section 13. • Tubing must be leak free. • Unit should be elevated, trapped and pitched to allow for drainage. • Low voltage wiring is connected.

AIR HANDLER AIR HANDLER 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.
