Features and Benefits
Unit Description
The vertical high-rise water-source heat pump is a floor mounted configuration available in a ¾ ton,
1 ton, 1¼ ton, 1½ ton, 2 ton and 3 ton sizes.
The unit cabinet may be ordered for early shipment to aid in early installation of drywall, plumbing
and electrical. See “Model Number Descriptions,” p. 14.The cabinet design is available in either an
88-inch height (free discharge) or 80-inch height (ducted) configuration. As many as 3 supply-air
discharges are available for the 1¼ ton-3 ton, free discharge cabinets to provide multiple supply-
air through one unit.
Air distribution is made through a rigid bar type extruded aluminum grille mounted to the
sheetrock. It is both durable and attractive in design.
The return-air panel is a hinged acoustical door, see Figure 1, p. 4.The door allows for easy access
to the unit’s filter and for maintenance of the equipment.
The hinged acoustical panel provides greater sound attenuation, and is mounted flush to the wall.
This panel is easily removed for filter maintenance or chassis removal through the magnetic catch
door. An optional tamper proof latch is available on the hinged door design to impede access if
required.
Blower/Motor Assembly
The unit’s blower/motor assembly includes double width, double inlet (DWDI) blower with direct
drive PSC motor or optional ECM motor for improved efficiency and power factor. It may be easily
removed for cleaning or service after removal of the unit chassis.The PSC motor is a multi-speed
design, factory wired to high speed or low speed (order specific).The tap will be wired and capped
inside the unit control box for easy field convertibility.The ECM motor is programmed to provide
four constant CFM profiles and is shipped on Profile B – the rated CFM of the unit.To change the
PSC speed tap or the ECM CFM profile, see installation manualWSHP-SVX03*-EN for instructions.
Controls
Standard controls include a 24V, micro-processor Deluxe controller for a wall-mounted thermostat
option.The thermostat is typically placed above the return-air door. Even though the thermostat
is considered to be unit mounted, the thermostat is mounted to the dry-wall that covers the front
of the unit.
