ENVISION CONSOLE - 50 HZ 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 - 50 HZ 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 - 50 HZ INSTALLATION MANUAL Installation Steps cont. Step 5: Provide Line Voltage Wiring Step 9: Set Unit Controls • 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. • Locate the “continuous fan/cycle fan” switch within the electrical compartment of the chassis and set to desired position.
ENVISION CONSOLE - 50 HZ 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 - 50 HZ INSTALLATION MANUAL Water Quality In ground water situations where scaling could be heavy or where biological growth such as iron bacteria will be present, a closed loop system is recommended. The heat exchanger coils in ground water systems may, over a period of time, lose heat exchange capabilities due to a buildup of mineral deposits inside. These can be cleaned, but only by a qualified service mechanic, as special solutions and pumping equipment are required.
ENVISION CONSOLE - 50 HZ INSTALLATION MANUAL System Cleaning and Flushing Cleaning and Flushing Ground Source Loop System Checkout Prior to start up of any heat pump, the water circulating system must be cleaned and flushed of all dirt and debris.
ENVISION CONSOLE - 50 HZ 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. Ensure 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. .09-.

ENVISION CONSOLE - 50 HZ INSTALLATION MANUAL Envision 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 - 50 HZ INSTALLATION MANUAL Envision Controls cont. The user selects either “Heat/Cool” or “Fan Only” on the mode switch, then either “High” or “Low” at the blower speed switch. The temperature can be controlled by rotating the thermostat control knob. Figure 6: Unit Mounted Control Component Sequencing Delays Components are sequenced and delayed for optimum unit performance. Short Cycle Protection The control allows a minimum on or off time of 5 minutes for short cycle protection.

ENVISION CONSOLE - 50 HZ INSTALLATION MANUAL Envision Controls cont. Lockout Mode Lockout mode can be activated by any of the following fault signals: refrigerant system high pressure, refrigerant system low pressure, freeze detection, and condensate overflow. When any valid fault signal remains continuously active for the length of its recognition delay, the controller will go into fault retry mode, which will turn off the compressor.

ENVISION CONSOLE - 50 HZ 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.
