Designed to maximize sensible and latent cooling performance at design conditions. System can operate from 30 F to 125 F without any additional controls.
Refrigerant
Non-chlorine, ozone friendly R-410A. Unit pre-charged with refrigerant.
Compressor
Scroll compressors resiliently mounted on rubber grommets for high performance, reliability and quiet operation.
Compressor Crankcase Heater
Protects against refrigerant migration that can occur during low ambient operation.
High Pressure Switch Check/Thermal Expansion Valves Reversing Valves
4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover.
Defrost Control
Provides a defrost cycle, if needed, every 30 or 60 or 90 minutes (adjustable).
Filter/Drier Freezestat
Protects the evaporator coil from damaging ice build-up.
Coil Construction
Copper tube construction, enhanced rippled-edge aluminum fins, flared shoulder tubing connections, silver soldered construction for improved heat transfer. Factory leak tested. Indoor Coil Cross row circuiting with rifled copper tubing.
Outdoor Coil
Two independent formed coils allow separation for cleaning.
Condensate Drain Pan
Plastic pan, sloped to meet drainage requirements of ASHRAE 62.1. Side or bottom drain connections. Reversible.
Outdoor Coil Fan Motor
Thermal overload protected, totally enclosed, shaft up, wire basket mount. Outdoor Coil Fan PVC coated fan guard furnished.
CABINET
Construction
Heavy-gauge galvanized steel panels with a two-layer enamel paint finish and full perimeter heavy-gauge galvanized steel base rail provides structural integrity for transportation, handling, and installation.
Air-Flow Choice
Units are shipped in down-flow (vertical) configuration, can be field converted to horizontal air flow configuration without a kit.
Power Entry
Through the base or horizontal knock- outs.
Insulation
All panels adjacent to conditioned air are fully insulated with non-hygroscopic fiberglass insulation. Base is fully insulated.
CONTROLS
Unit Control
All control voltage is provided via a 24V (secondary) transformer with built-in circuit breaker protection.
Heat/Cool Staging
- Capable of up to 2 heat / 2 cool staging with a third party DDC control system or thermostat.
Low Voltage Terminal Block
- Provides screw terminal connections for thermostat or controller wiring. Night Setback Mode - Saves energy by closing outdoor air dampers and operating supply fan on thermostat demand only.
BLOWER
A wide selection of supply air blower options are available to meet a variety of air flow requirements.
Motor
Supply Air Blower
Forward curved blades, blower wheel is statically and dynamically balanced. All belt drive motors have adjustable pulley for speed change.
