General Installation Information
ENVISION CONSOLE INSTALLATION MANUAL
Safety Considerations
WARNING: Before performing service or
maintenance operations on a system, turn off main
power switches to the indoor unit. If applicable,
turn off the accessory heater power switch.
Electrical shock could cause personal injury.
Installing and servicing heating and air conditioning
equipment can be hazardous due to system pressure and
electrical components. Only trained and qualified service
personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform
the basic maintenance functions of cleaning coils and
cleaning and replacing filters. All other operations should
be performed by trained service personnel. When working
on heating and air conditioning equipment, observe
precautions in the literature, tags and labels attached to the
unit and other safety precautions that may apply.
Follow all safety codes. Wear safety glasses and work
gloves. Use a quenching cloth for brazing operations and
have a fire extinguisher available.
Moving and Storage
Move units in the normal “up” orientation. Do not stack
units. When the equipment is received, all items should be
carefully checked against the bill of lading to be sure all
crates and cartons have been received. Examine units for
shipping damage, removing the units from the packaging
if necessary. Units in question should also be internally
inspected. If any damage is noted, the carrier should make
the proper notation on the delivery receipt, acknowledging
the damage.
Refrigerant Systems
To maintain sealed circuit integrity, do not install service
gauges unless unit opertion appears abnormal. Compare
the change in temperature on the air side as well as the
water side to the Unit Operating Parameters tables. If the
unit’s performance is not within the ranges listed, and the
airflow and water flow are known to be correct, gauges
should then be installed and superheat and subcooling
numbers calculated. If superheat and subcooling are outside
recommended ranges, an adjustment to therefrigerant
charge may be necessary.
Water Piping
The proper water flow must be provided to each unit
whenever the unit operates. To assure proper flow, use
pressure/temperature ports to determine the flow rate.
These ports should be located at the supply and return
water connections on the unit. The proper flow rate cannot
be accurately set without measuring the water pressure
drop through the refrigerant-to-water heat exchanger.
All source water connections on commercial units are
fittings that accept a male pipe thread (MPT). Insert the
connectors by hand, then tighten the fitting with a wrench
to provide a leakproof joint. When connecting to an open
loop (groundwater) system, thread any copper MPT fitting
into the connector and tighten in the same manner as
described above.

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: Mark Unit Position
• Ensure that floor is level. If shims are required, make sure that the entire compressor compartment area is uniformly
shimmed and that the backplate mounting height is increased by the thickness of the shims used.
• Position backplate in desired equipment location. To further reduce the operating sound level of the unit, 1/8-inch thick
rubber matting may be placed under the chassis to eliminate vibration on hard flooring surfaces. (Make sure back plate
is level).
• Mark and cut floor or wall penetrations for electrical wiring, water and condensate piping.
Optional Electrical Disconnect and Motorized Outside Air Damper
• Mark and cut wall penetrations for field fabricated outside air duct sleeve.

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 piping should be run through the wall or floor penetration and terminate with a ball valve.
The piping material used must comply with all local codes.
• Refer to: System Cleaning and Flushing procedures.

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. Drive (2) screws through holes in lip of backplate into top flange of chassis.
Step 7: Final Electrical Connection
• Install flexible electrical conduit between the backplate or electrical disconnect and the unit mounted junction box.
• Make final wiring connections in disconnect and junction box, taking care to replace all covers when done. Wiring must
conform to NEC and/or all local codes. Refer to Electrical Data.
NOTE: It is necessary to make final wiring connections prior to securing unit chassis to back plate on right-hand piping
models with electrical disconnect.
Step 8: Final Water Connection
• For ease of installation and sound attenuation, high pressure (recommended) flexible hoses with a swivel fitting should
be provided. Apply Teflon® tape or sealant compound to threaded hose fittings.
• Combination shut-off/balancing valves should be installed on both the supply and return water lines of the unit.
• Flow control valves should be installed on the water discharge line.
• It is recommended that P/T ports be installed on the supply and return water lines.
Step 9: Set Unit Controls
• Locate the “continuous fan/cycle fan” switch within the electrical compartment of the chassis and set to desired position.
(Remote wall thermostat units do not use this optional switch.)
• Optional Control SettingsRemote Thermostat - Run low voltage wiring from unit to the desired thermostat location.
Mount and wire thermostat according to manufacturer’s recommendations.
Motorized Outside Air Damper - Locate the “damper on/damper off” damper switch within the electrical compartment
of the chassis and set to desired position.
Emergency Electrical Heat - Locate the “electric heat/normal/boilerless” control switch within the electrical compartment of the chassis and set to desired position.
Step 10: Secure the Cabinet Cover
• Position and lower cabinet over unit chassis. Apply pressure to the front of the cabinet to ensure that the back lip of the
cabinet hooks over the tabs provided on the backplate.
• Secure cabinet to chassis with mounting screws provided.
Step 11: Perform Final Unit Check
• Measure the pressure drop across the water coil and monitor water or air temperatures in both heating and cooling
modes. The measured values should fall within the acceptable ranges shown in the Startup Performance table.
