Water Loop Piping:
1). The performance and reliability of the new
Adirondack-Aire unit depends on proper water flow rate
and water quality. Inadequate water flow rate and/or
poor water quality or contamination will result in poor
performance and may shorten unit life. Failure to
provide adequate flow and properly maintained water
quality may void the new unit Limited Warranty.
2). General: Waterlines must be installed in accordance
with local and national codes. Care must be taken by
the installing contractor to prevent dirt or foreign
matter from entering the pipes or piping components
3
during construction/installation.
The water lines should be routed so as not to interfere
with access to the unit or filter removal. The use of a 2
or 3 foot flexible hose with a swivel type fitting may
simplify the connections and prevent vibration. It is
recommended, at minimum, that a combination
balancing and close-off (ball) valve be installed at the
return and a gate or ball valve be installed at the supply.
The return valve can be adjusted to obtain the proper
water flow.
Installing the New Chassis:
1) Carefully load the new chassis onto the lift used to
remove the old unit. Orient the chassis properly to line
up with the ductwork, water lines, and power
connection. The new unit connection sizes and
locations are identical to the old unit.
2) Remove the chassis panel that provides access to the
power connection and controls.
3) Locate and remove the hanger bracket grommets
/parts bag packed inside.
4) Mount the grommets to the hanger brackets at the
four corners of the unit.
5) Inspect the hanger rods and hardware that mount
the unit to the ceiling. Replace any suspect items.
6) Slowly and carefully raise the unit into position and
secure to the hanger brackets at the four corners of the
unit. Double nut the hangers and do a final inspection
of all mounting hangers and hardware.
7) Failure of hanger hardware can result in a falling
unit and personal injury or death! Do not take chances.
Slowly lower the lift from under the unit taking care to
see that all hangers are bearing the weight of the unit
without strain before removing the lift.
8) Connect duct(s) to the flanges at the end(s) of the
chassis.
9) Connect water lines to the water connection points
on the new unit, being careful to connect water inlet
and outlet properly. If pipe thread fittings are used, use
Teflon thread tape or pipe dope. When tightening the
water connections and drain at the unit use a wrench
to support the fittings
10) Connect power supply wiring and conduit at the
chassis. Wire the thermostat connections to the pigtails
provided in accordance with the unit-wiring diagram.
Be sure all wiring complies with all of the requirements
outlined above.

11) Replace unit panel.
12) Set the thermostat to the 'Off' position and turn the
main power on at the breaker panel.
Use of new Remote Thermostats:
The Adirondack-Aire 814 replacement chassis uses the
same operating logic as the original and is designed to
work with the existing controls and thermostat. The
reversing valve is energized in heating. If you are
upgrading to a new thermostat be sure to use a
thermostat that has the same signal logic as the original.
Proper temperature control and unit operation depends
on proper thermostat selection and location. Refer to the
thermostat manufacturer's installation instructions for
specific recommendations. Good practice is to avoid
outside walls, locations where the sun may shine directly
on the thermostat, and locations where the air from
supply registers or unit outlets blow on the thermostat.
Also avoid locations where the thermostat could be jarred
by a closing door
Pre-Start Quick Check List:
Before proceeding with the start-up of individual units,
the following should be verified:
Has the water loop system been flushed and cleaned of
construction debris?
Is the water flow established and circulating through all
units?
Has the water loop system been balanced to design flow
rates?
Is the water temperature within normal operation range?
Has heat transfer fluid been added in the proper mix to
prevent freezing in closed systems that could, under any
condition, fall below the freezing point during either the
heat pump operating cycle or the down cycle? The heat
transfer fluid must have extended range capability (down
to 20 F). A low temperature (20 F) freezestat must also
be used if units are to be operated under these
conditions.
Is the unit properly sized, located, and level with proper
clearances?
Is the filter in place and the correct size.
Is the wiring properly sized and run in according with
the unit wiring diagram?
Are all wiring connections tight including those in unit
and compressor electrical boxes?
Has the unit been properly grounded and fused with
the recommended fuse size?
than 5 degrees or shutting the unit 'off' can actually cost
more than leaving the setting at a constant temperature.
Has all work been done in accordance with applicable
local and national codes?
6). IMPORTANT! Wait at least 3 minutes after turning
the air conditioner off before trying to restart it. This
gives the unit the time needed to stabilize before
restarting. Failure to do so may cause unit damage and
failure.
Are all covers and access panels in place to prevent air
loss and safety hazards?
Warning: Bodily injury can result from high voltage
electrical components. If operating checks must be
performed with the unit operating, it is the technician’s
responsibility to recognize there hazards and proceed
safely. Failure to do so could result in severe personal
injury or death due to electrical shock or contact with
moving parts.
7). A properly installed and sized unit will not cycle
more than 10 times per hour. If you notice more
frequent starts call your service contractor.
Operation of the unit is automatic and will provide
cooling and heating depending on the settings of the
thermostat.
814 Heating Operation:
814 Series Heat pumps are designed to also provide
heating. Setting the switch or thermostat or control
panel to the 'Heat' position and setting the desired
temperature activates heating operation. When heating,
the 'Auto' fan position is recommended. Adjust the
temperature set point above room temperature. The
reversing valve should be energized. Warm air should
blow from the registers. A water temperature decrease
of approximately 5-9 F leaving the heat exchanger
should be noted. The blower and compressor operation
should be smooth.
814 Models - Cooling Operation:
1). Set the switch on the wall thermostat or unit control
panel to the 'cool' position.
Do a final visual inspection of the entire installation and
complete any final details and clean up.
Important: Unit should not be operated in construction
phase until dry wall is complete. The coil will foul and
warranty will be void.
To Operate:
2). Set the desired temperature you want to maintain by
moving the temperature setting lever or dial on the
thermostat. If the room is warmer than the setting, the
unit will turn on and begin to blow cool air after a few
minutes. Note that a warm humid room or building
may take several hours of continuous operation to cool
to the thermostat set point the first time. Once the set
temperature is reached the unit will cycle on and off.
3). Set the 'Fan' switch on the thermostat to 'auto' if
you want the fan to run only when cooling is needed or
to 'on' if you want continuous air circulation. The 'on'
setting of the fan generally provides better temperature
control by eliminating stagnant air.
4). Check unit operation. It should be supplying cool
air to the conditioning space. The reversing valve will
be de-energized; water leaving the heat exchanger
should be warmer than the entering water temperature
(approximately 9-12 F rise); blower operation should be
smooth; compressor and blower amps should be within
data plate ratings.
5). For energy conservation reasons you may want to set
your thermostat at a higher temperature when you are
away. Do not raise the temperature setting by more
than 5 degrees. Changing the temperature by more
Final Inspection:
Maintenance
Unit performance is maintained at optimum level and
maintenance of the unit simplified by implementing the
following preventive measures.
1). The heat pump is furnished with a permanent,
cleanable or a fiberglass throwaway type air filter. The
unit should not be operated without this filter installed.
2). Filters should be inspected at least every three
months, and replaced or cleaned when dirty. Unit
operation becomes very inefficient with dirty filters.
Unit warranty is void if filters are not maintained
properly.
3). Condensate drains can pick up lint and dirt,
especially with dirty filters. Inspect, and if dirty, clean
the condensate drain pan twice a year to avoid the
possibility of overflow (see section “Inspecting and
Cleaning Drain Pans).
4). Microbial growth can occur in water source heat
pumps anywhere in the air stream where moisture exists.
ASHRAE standards 62-89 recommends that these
surfaces be inspected and cleaned to limit
contamination. This typically includes surfaces
beginning at the finned coil, drain pan, insulation, and
fan/blowers.
5). It is important to check the cleanliness of the waterto-refirigerant heat exchanger. Should it become
contaminated with dirt and scaling as a result of poor

back-flushed and cleaned with a chemical that will remove
the scale. This service should be performed by an
experienced service technician.
water quality treatment. The heat exchanger will have to be
back-flushed and cleaned with a chemical that will remove
the scale. This service should be performed by an
experienced service technician.
6). A strainer (20 mesh or greater) may be used to keep
debris from entering the system and to help ensure a clean
system. This is highly recommended on open well and open
tower systems.
7). Check the tightness of the various wiring connections
within the control panel.
8). The direct-drive blower motors in 814 units have
permanently sealed lubricated bearings and do not require
periodic oiling. Life of the bearings may however be
extended by adding a few drops of 20W non-detergent oil
through the oil ports twice a year. Do NOT over oil.
Inspecting and Cleaning Drain Pans
Note : Standing water in drain pans can promote microbial
growth (mold) which may cause unpleasant odors and
serious health related indoor air quality problems. If
microbial growth is found, it must be removed immediately
and the unit must be properly cleaned and sanitized.
The condensate drain pan and drain line must be checked
to ensure that the condensate is draining freely. This
inspection should occur a minimum of every six months or
more often if necessary.
If evidence of standing water or condensate overflow is
found steps should be taken to identify and repair the cause
immediately. Refer to the troubleshooting section of this
manual for possible cause and solutions. If microbial
growth in the drain pan is observed, it should be cleaned
and removed immediately. Drain pans should be cleaned
using the following procedure:
1). Disconnect all electrical power to the unit.
2). Wear the appropriate personal protective equipment.
3). Remove all standing water.
4). Use a scraper or other tool to remove any solid matter.
Remove solid matter with a vacuum device that utilizes
High Efficiency Particulate Arrestance (HEPA) filters.
5). Thoroughly clean the contaminated areas with a mild
bleach and water solution or an EPA approved sanitizer
specifically designed for HVAC use. Carefully follow the
sanitizer manufacturer’s instructions regarding this product.
6). Immediately rinse the drain pan throughly with fresh
water to prevent potential corrosion from the cleaning
solution, the drain pan and drain line components.
7). Determine and correct the cause of the microbial
contamination.
8). Be careful that the contaminated material does not come
into contact with other areas of the unit or building.
Properly dispose of all contaminated materials and used
cleaning solution. Store unused solutions according to
solution manufacture’s directions.

materials and used cleaning solution. Store unused
solutions according to solution manufacture’s directions.
9). Allow the unit to dry thoroughly before putting the
system back into service.
Inspecting and Cleaning Finned Coils:
Coils become externally fouled as a result of normal
operation. Dirt on the surface of the coil reduces it’s
ability to transfer heat which can result in comfort
problems, increased resistance to airflow and result in
increased operating energy costs. If the dirt on the surface
of the coil becomes wet, such as commonly occurs with
cooling coils, microbial growth can result which may cause
unpleasant odors and serious health related indoor air
quality problems.
Coils should be inspected at least every six months or more
often as necessary. The frequency of the required
inspection/cleaning is dependent on the operating hours of
the system, filter maintenance and efficiency, and dirt load.
The following is the suggested method of cleaning coils:
1). Disconnect all electrical power to the unit.
2). Wear the appropriate personal protective equipment.
3). Gain access to the coil section of the unit (both sides).
4). Using a soft brush, remove loose debris from both sides
of the coil.
5). Mix a high quality coil cleaning detergent with water
according to the manufacturers instructions. If the
detergent is strongly alkaline after mixing (8.5 pH or
higher), it must contain a corrosion inhibitor. Carefully
follow the cleaning solution manufacturers instructions
regarding the use of the product.
6). Placed the mixed solution in a pump sprayer or high
pressure sprayer. If a high pressure spryer is used, note the
following:
A. Maintain a minimum nozzle spray angle of 15
B. Spray perpendicular to the coil face.
C. Protect other areas of the air handler and internal
controls from contract with moisture or the cleaning
solution.
D. Keep the nozzle at least 6 inches from the coil.
E. Do NOT exceed 600psi.
7). Spray the leaving air side of the coil first, then the
entering air side. Use a block-off to prevent spray from
going through the coil and into a dry section of the unit
and/or system duct-work. Carefully follow the cleaning
solution manufacturers usage instructions.
8). Thoroughly rinse both sides of the coil and the drain
pan with cool, clean water.
9). Repeat steps 7 and 8 as necessary.
10). Straighten any coil fins that may have been damaged
during the cleaning process. Use a fin comb.
11). Confirm that the drain line remains open following
the cleaning process.
12). Replace all panels and parts. Restore electrical power
to the unit.
13). Allow the unit to dry before putting unit back in
service.
14). Be careful that the contaminated material does not
come into contact with other areas of her unit or
building. Properly dispose of all contaminated materials
and used cleaning solution. Store unused solutions
according to solution manufacturer’s directions.
