Use of a condensate removal pump is permitted when nec- essary. This condensate pump should have provisions for shutting off the control voltage should a blocked drain occur. A trap must be installed between the unit and the conden- sate pump.
IMPORTANT NOTE: The evaporator coil is coated with oils that may dissolve styrofoam and certain types of plastics. Therefore, a removal pump or float switch must not contain any of these materials.
Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling season.
When coils are installed above ceilings, or in other locations where damage from condensate overflow may occur, it is MANDATORY to install a field fabricated auxiliary drain pan under the coil cabinet enclosure. Drain lines from the auxiliary pan must be installed and terminated so that the homeowner can see water discharges.
Achieve 2% Low Leakage Rate
Ensure that the Neoprene gasket with PSA remains intact on all surfaces that the access panels are secured to. These surfaces are the entire length of the wrapper and areas be- tween the upper tie plate, upper and lower access panels. Be sure that upper access panel breaker insert gasket is in- tact and also flowrator gasket is installed on the lower ac- cess panel. An additional drain hole cover is required.
•Return and supply ducts are sealed.
•Unit is elevated when installed in a garage or where flammable vapors may be present.
•Unit is protected from vehicular or other physical dam- age.
•Return air is not obtained from any areas where there may be objectionable odors, flammable vapors or prod- ucts of combustion such as carbon monoxide (CO), which may cause serious personal injury or death.
Regular Maintenance
HIGH VOLTAGE!
Disconnect ALL power before servicing or installing this unit. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death.
The only item to be maintained on a regular basis by the user is the circulating air filter(s). Filter should be cleaned or re- placed regularly. A certified service technician must perform all other services.
NOTE: DO NOT USE THESE DIAGRAMS FOR MODELS OTHER THAN ASPF. SEE INSTALLATION AND OPERATING INSTRUCTIONS SPECIFICALLY FOR EACH MODEL.
ASPF Motor
The ASPF air handler features an energy efficient blower motor. The motor is a constant torque motor with very low power consumption. The motor is energized by 24 VAC. Ad- just the CFM by changing the 24 VAC leads to the desired speed on the terminal block.
The ASPF motor blower speed is programmed to deliver ad- equate airflow at rated external static pressure and with 60 second off time delay. For details, refer to the specification sheet applicable to your model.
CFM Delivery
Table 9 shows the CFM speed tap settings for the ASPF.
Start-Up Procedure
•Prior to
•All panels must be in place and secured. For Air Tight application, neoprene gasket must be positioned at pre- scribed locations to achieve 2% leakage.
•Tubing must be leak free.
•Unit should be elevated, trapped and pitched to allow for drainage.
•Low voltage wiring is connected.
•Auxiliary drain is installed when necessary and pitched to allow for drainage.
•Drain pan and drain tubing has been leak checked.
