The device described in the manual is the MagicPak EWC V-Series™ All-In-One™ HVAC system, a self-contained electric heating and cooling unit. It is designed for indoor installation only, with service access and duct connections required to be inside the building.

Function Description:

The MagicPak EWC V-Series™ unit provides both electric heating and cooling for indoor spaces. It is a self-contained system, meaning all necessary components for refrigeration and heating are integrated into a single unit. The unit operates automatically, providing heating or cooling based on the thermostat settings. It features a direct drive, multi-speed blower motor for air handling.

Important Technical Specifications:

Compliance: The unit complies with Canadian Standards Association CAN/CSA-C22.2 No. 236 (latest edition), Underwriters Laboratories UL 1995, and AHRI Performance Standard 210/240. Any alteration of internal wiring voids these certifications and warranties.
Power Supply: Factory-wired for a 230-volt power supply. For 208-volt power supply, a wire connection on the unit transformer must be changed from the 240V terminal to the 208V terminal (refer to wiring diagram).
Operating Voltage: Minimum operating voltage for 208-230 volt models is 197 volts. Units must not be installed where voltage exceeds 10% of the indicated rating plate voltage. Operation on improper voltage voids the compressor replacement warranty.
Refrigerant: The Cooling Chassis is charged with R410A refrigerant.
Dimensions (approximate, based on diagrams):
- Front View: 27-7/8" wide, 43-3/16" high. Supply opening is 16" wide. Return opening is 22" wide.
- Side View: 29-7/16" deep, 43-3/16" high.
- Top View: 27-7/8" wide, 29-7/16" deep. Line voltage and thermostat wiring connections are located on the top.
Ductwork:
- Supply duct connects to the top of the unit using a canvas or flexible connection.
- Return duct connects to the bottom of the unit, requiring a straight piece of duct 22" wide by 6" deep, flanged over existing flanges inside the unit.
Filter Area (Minimum Required Surface Area for Disposable Filters):
- EWC*12: 300 sq. in.
- EWC*18: 480 sq. in.
- EWC*24: 480 sq. in.
- EWC*30: 480 sq. in.
Airflow Performance (SCFM) as a Function of External Static Pressure: (Detailed table provided in manual, varies by model and speed tap). For example, EWC0512P12B at TAP 1 (HEAT) and 208 or 230V ranges from 615 SCFM at 0.1" w.c. to 525 SCFM at 0.5" w.c. EWC1512P30B at TAP 5 (COOL) and 208 or 230V ranges from 950 SCFM at 0.1" w.c. to 865 SCFM at 0.5" w.c.

Usage Features:

Thermostat Control: The unit's operation is controlled by a thermostat. Users set the system switch to "HEAT" or "COOL" and adjust the temperature scale to the desired setting.
Blower Operation: The blower can be set for continuous operation ("ON" setting on the thermostat fan switch) or cycle with the thermostat ("AUTO" setting).
Shut Down: For temporary shutdown, set the thermostat system switch to "OFF." For prolonged shutdown, also turn off the electrical power supply.
Two-Stage Compressor: For EWC*30 models, a two-stage thermostat is recommended to achieve the highest efficiency and full use of the two-stage compressor.
Condensate Drain: A plastic drain tube (5/8" O.D.) is supplied for condensate removal. The drain line should pitch gradually downward at least 1" per 10 feet of horizontal run to an open drain trap.

Maintenance Features:

Cooling Chassis: The refrigeration system is a closed, self-contained system and normally requires no maintenance.
Air Filter: A permanent-type filter is furnished with the unit, located in front of the evaporator coil behind the filter access panel.
- Cleaning: The filter should be cleaned at least once during each heating and cooling season, or more frequently in dusty conditions. To clean, shake off excess dirt, use a vacuum cleaner, or wash with soap/detergent and re-install when dry. The filter does not need to be oiled.
- Alternative Filter Location: If the filter is mounted exterior to the unit (in the return ductwork), the permanent filter can still be used, or a disposable filter with the specified minimum surface area can be used.
Condenser Coil: The condenser coil should be cleaned if covered with foreign material (lint, leaves, obstructions).
Motors: Motors are permanently lubricated and typically do not require re-oiling.
Cooling Chassis Removal (for major repairs/servicing):
1. Shut off main power supply.
2. Remove filter access panel and cooling controls panel.
3. Remove drain hose from drain pan.
4. Disconnect plug-in electrical connectors (grasp connector handle, not wires).
5. Disconnect two power leads from the contactor.
6. Remove screws from the blower panel and control panel.
7. Drape power wires and wire harnesses out of the cabinet and tape to the upper panel.
8. Carefully slide out the chassis, ensuring no damage to seals, parts, or wiring. Note: Tubing is not to be used as a handle.
- Re-installation: Reverse the removal procedure, ensuring the chassis is fully inserted, side flanges engage with sealing strips, and all electrical connections are reconnected before restoring power.
Heating Section: No maintenance is necessary for the electric heating elements.
Wiring Check: Periodically check that no wiring is loose or missing, and that the plug-in electrical connector between the cooling chassis and main control compartment is firmly seated.
