ENVISION CONSOLE INSTALLATION MANUAL Installation Steps Step 1: Unpack Equipment and Inspect for Damage Step 2: Determine Equipment Location • • • • • Choose level flooring surface (Correctable with shims. Do not pitch towards drain.) Location of wall support and fasteners required to secure chassis backplate. Easy access for both installation and service. Consider availability and ease of wiring, water piping and condensate drain. No obstructions to block airflow in front of the unit.
ENVISION CONSOLE INSTALLATION MANUAL Installation Steps cont. Step 4: Provide Water and Condensate Drain Connections • A two-pipe reverse return piping configuration is recommended as it equalizes the piping circuit lengths and delivers even water flow to each unit. A direct return piping configuration may be used, but it may be difficult to achieve and maintain proper water flow to the units. • An air vent must be installed in the water distribution system.
ENVISION CONSOLE INSTALLATION MANUAL Installation Steps cont. Step 5: Provide Line Voltage Wiring • Check unit data plate located on control side of chassis for ampacity and fuse size. • Remove electrical knockouts from chassis backplate. • Run line voltage wiring through knockout and secure wiring to backplate or disconnect. Step 6: Chassis Installation • Level and secure backplate to wall. • Position the chassis against back plate.
ENVISION CONSOLE INSTALLATION MANUAL Installation Steps cont. Field Converting Console Chassis is normally configured with controls on right end and piping on left end (see Figure 3 top view). In this position panel number 1 would be positioned against wall or back plate. Unit may also be turned 180° against wall or back plate. In this position controls will be on left end and piping on right end panel number 2 would be positioned against wall or back plate.
ENVISION CONSOLE INSTALLATION MANUAL System Cleaning and Flushing Cleaning and Flushing Prior to start up of any heat pump, the water circulating system must be cleaned and flushed of all dirt and debris. If the system is equipped with water shutoff valves, the supply and return runouts must be connected together at each unit location (This will prevent the introduction of dirt into the unit, see Figure 7). The system should be filled at the water make-up connection with all air vents open.
ENVISION CONSOLE INSTALLATION MANUAL Open Loop Ground Water Systems Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in unit capacity data tables in the specification catalog. 1.
ENVISION CONSOLE INSTALLATION MANUAL Electrical Connections General Be sure the available power is the same voltage and phase as that shown on the unit serial plate. Line and low voltage wiring must be done in accordance with local codes or the National Electric Code, whichever is applicable. 208 Volt Operation All Envision Series 208/230 units are factory wired for 230 volt operation. For 208 volt operation, the red and blue transformer wires must be switched.

ENVISION CONSOLE INSTALLATION MANUAL Envision Console Controls Control General Description CCM Control The CCM (Compressor control module) is a more reliable replacement for electro-mechanical control applications. It features a small microprocessor board that handles the lockout function of the unit. A second microporcessor handles the unit mounted thermostat for maintaining accurate room temperature. Residential and commercial applications requiring minimal but reliable controls.
ENVISION CONSOLE INSTALLATION MANUAL Envision Console Controls cont. The user selects either “Heat/Cool” or “Fan Only” on the mode switch, then either “High” or “Low” at the fan speed switch. The temperature can be controlled by rotating the thermostat control knob. Figure 6: Unit Mounted Control Optional Versatec Microprocessor Control Features The Versatec microprocessor board provides control of the entire unit as well as outputs for status modes, faults and diagnostics.
ENVISION CONSOLE INSTALLATION MANUAL Envision Console Controls cont. prevent loss of refrigerant charge and a low suction temperature thermistor for freeze sensing. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is stopped.
ENVISION CONSOLE INSTALLATION MANUAL Envision Console Controls cont. Optional FX10 Control Random Start A delay of 1 to 120 seconds is generated after each powerup to prevent simultaneous startup of all units within a building after the release from an unoccupied cycle or power loss. Emergency Shutdown A field-applied dry contact can be used to place the control into emergency shutdown mode. During this mode, all outputs on the board are disabled.

ENVISION CONSOLE INSTALLATION MANUAL Preventive Maintenance Water Coil Maintenance Condensate Drain 1. Keep all air out of the water. An open loop system should be checked to ensure that the well head is not allowing air to infiltrate the water line. Lines should always be airtight. 2. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the discharge line to prevent loss of pressure during off cycles.
