Installation
CAUTION!
Poor or inadequate installation may result in
noisy unit operation or unattractive installation.
⚠
CAUTION!
⚠
The installation of Console Water-Source Heat Pumps
and all associated components, parts and accessories
that make up the installation shall be in accordance with
the regulations of ALL Authorities having jurisdiction
and MUST conform to all applicable Codes. It is the
responsibility of the Installing Contractor to determine and
comply with ALL applicable Codes and Regulations.
Note: An Installation Checklist is provided in this
manual. Complete this checklist after all installation
procedures are completed. A periodic maintenance
checklist provided in the Maintenance section outlines
recommended maintenance schedules. A Start-Up
Inspection Log is also included at the end of this
manual to encourage thorough unit checkout at initial
start-up. These checklists are not a substitute for the
detailed information found in the Installation section of
this manual.
1. Console units are typically installed along an outside
wall of the room. Provide adequate space in front
of the unit for service and maintenance. Locate
the Console Unit so that it provides adequate air
circulation throughout the room.
2. Unpack the Console Unit from the shipping carton.
Remove the front cabinet by lifting up and away
from the backplate. Protect the cabinet from damage
during installation by returning it to its original
packaging until required.
3. Using a carpenter’s square and a level, ensure the
unit is level. Shim the unit if necessary to assure
proper installation.
4. Select the proper fasteners to connect the backplate
securely to the wall.
5. Fasten the backplate onto the wall through the screw
holes located in the back flange. Secure the subbase
in place.
6. Remove subbase shipping support bracket and discard.
7. Make all necessary electrical connections as described
in the Electrical Wiring section of this manual. Consult
the wiring diagram to ensure proper hook-up.
8. Connect the final piping as described in the Supply
and Return Piping and Condensate Piping section
of the manual. Install shut-off valves, piping and/or
hoses and other accessories as specified.
9. Before making the final water connections, flush the
system as described in the Start Up section of this
manual. After flushing the system, connect piping and
hoses to the proper supply, return and condensate
connections of the unit.
Note: When necessary, use adapters to connect
hoses.
10. Install any other system components as required
following manufacturer’s instructions.
11. After Start-up, reinstall the front cabinet by carefully
lowering the front cabinet over the chassis onto the
backplate.
Supply and Return Hoses - Optional pressure-rated
hose assemblies 400 psi [2758 kPa] are available for use
with Console Units. Use the following guidelines when
installing supply and return hose assemblies.
1. Install supply and return hoses fitted with swivel-joint
fittings at one end to prevent the hose from twisting.
2. Use adapters to secure the hose assembly to the unit
and the riser.
3. Do not allow the hose to twist during installation.
Twisting may damage the hose wall or the interior
rubber compound.
4. Use pipe joint compound sparingly on the pipe
threads of the fitting adapters.
5. Prevent sealant from reaching the flared surfaces of
the joint.
6. Do not use pipe joint compound when teflon thread
tape is pre-applied to hose assemblies or when
flared-end connections are used.
7. Maximum torque which may be applied to brass
fittings is 30 ft-lbs [41 N-m]. When a torque wrench
is not used, tighten brass fittings finger-tight plus one
quarter turn.
8. Tighten steel fittings as necessary.
9. Shut-off/balancing valves, flow indicators, and drain
tees in the supply runout and return at each floor to
aid in loop balancing and servicing.
