12) Fresh Air Door
The Fresh Air Door is an "intake" system. The fresh air door is opened via a slide on the front of the chassis located just above the indoor coil. Move the slide left to open and right to close the fresh air door. The system is capable of up to 60 CFM of fresh air @ ~.3" H20 internal static pressure.
13) Condensate Disposal System
The VPDP1 drain pan features two 3⁄4 female PVC fittings to attach a drain connection to on the left or right side of the drain pan. Condensate piping can be routed to the left, right or beneath the unit platform.
See page 8 or the drain pan installation manual for more information.
Part 1: The system’s first stage increases energy efficiency utilizing a factory installed fan that slings the cold condensate onto the hot outdoor coil.
Part 2: When high outdoor humidity prevents the slinger from disposing of all the condensate, the excess condensate overflows into the condensate drain pan and out of the 3⁄4" internal drain connections.
Part 3: If Parts 1 & 2 fail for any reason, excess condensate overflows from a spillway directly into the wall plenum to the outside of the building. IF
THIS OCCURS, THIS IS YOUR WARNING THAT THE CHASSIS OR DRAIN NEEDS SERVICING.
IV. Service & Warranty
14) Servicing / Chassis Quick Changeouts
The chassis is designed for quick disconnect and change out. For minor electrical service, the control box cover lifts straight up after the screws & disconnect head are removed. For major electrical, refrigeration and fan service the chassis may be removed from utility closet.
To Remove the Chassis from the Closet:
A.Switch the wall Thermostat off.
B.Pull the Power Disconnect located in the front of the chassis.
C.Disconnect the thermostat wiring harness.
D.Disconnect the electrical connection.
E.Disconnect the ductwork.
F.Slide the chassis out of the wall plenum.
G.Lift the chassis out of the utility closet.
Electrical shock and moving parts hazard can cause injury or death. Pull out the disconnect head found on the front of the chassis before servicing.
15) Routine Maintenance
Performing Routine Maintenance
With the proper maintenance and care, your system will operate economically and dependably. Maintenance can be accomplished easily by referring to the following directions. However, before performing any maintenance, consider these important safety precautions:
WARNING: Electrical Shock Hazard. Before attempting any service work or routine maintenance, turn off all electrical connections to the unit. Failure to do so may result in property damage, personal injury and/or death.
CAUTION: Although great care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit.
Replace Air Filter
Adirty air filter reduces the efficiency of your
To replace the filter (chassis mounted return air filter):
1.Slide the filter clear of the filter rails.
2.Remove the filter.
3.Install new disposable filter.
CAUTION: Do not operate your system without a filter in place, nor block the front of the unit return air opening.
Inspect and Clean Indoor-air Coil
Eventually, minor amounts of lint and dirt may pass through the filter and collect on the
a vacuum cleaner. Care must be taken to avoid bending the aluminum fins on the coil. Bent fins should be straightened using a special fin tool available from most HVAC service technicians.
Inspect Outdoor-air Intake and Exhaust
The unit’s
Inspect and Clean Condensate Drain
The condensate drain must be routed to a suitable drainage area. Check the unit condensate drain periodically. Keep it free of anything that may block or impede the flow of condensate water. If there is any accumulation of foreign matter in the drain pipe, it should be removed and cleaned. The entire drain line must be protected from freezing.
16) Warranty
All service work must be done by a qualified servicer. See Warranty on the next page, and consult your dealer or contractor for details
