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. Step 3:

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. • The supply and return water

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. 1.5-2
