UNIT INSPECTION CHECKLIST

Unpack all components of the shipping skid.
 Check carefully for any shipping damage. If any damage is found it must be reported immediately
and a claim made by the equipment receiver against the transportation company.
 Visually inspect the components for shipping damage as soon as possible after delivery, before it is
stored. Concealed damage must be reported within 15 days.

If concealed damage is discovered, stop unpacking the shipment.
 Do not remove damaged material from the receiving location. Take photos of the damage, if
possible. The owner must provide reasonable evidence that the damage did not occur after delivery.
 Notify the carrier’s terminal of damage immediately by phone and by mail. Request an immediate
joint inspection of the damage by the carrier and the consignee.
 Do not attempt to repair any damaged parts until the parts are inspected by the carrier’s
representative.
JOBSITE INSPECTION CHECKLIST
Always perform the following checks before accepting a unit:

Verify the nameplate data matches the data on the sales order and the bill of lading.

Verify the nameplate electrical specifications complies with the power supply.
 Visually inspect the exterior of the unit, for signs of shipping damage. DO NOT SIGN the bill of
lading accepting the unit(s) until inspection has been completed. Check for damage promptly after the
unit(s) are unloaded. Once the bill of lading is signed at the jobsite, the unit(s) are now the property of the
SOLD TO party and future freight claims MAY NOT be accepted by the freight company.
 Verify the refrigerant charge has been retained during shipment by use of gauges. Shrader taps are
located internal to the cabinet.
 After assuring that the charge has been retained, reinstall the Schrader caps to assure that refrigerant
leakage does not occur.

CLEANING AND FLUSHING THE WATER SYSTEM
After the piping system is complete, the flexible hose connectors should be doubled back to
complete the water circuit external to the unit (avoiding trash settle-out in the condenser). See
Figure A Flushing Water Loop. An extra pipe may be necessary to connect the hose kits.
Figure A. Flushing Water Loop
 Verify the water circulation system has been filled with clean water using the water make up
connections. Note: Air vents should be open during filling.
 Verify that with the air vents closed, the circulating pumps have been started and then crack the air
vents to bleed off the trapped air, assuring circulation through all components of the system. Note: Make
up water must be available to the system to replace the volume formerly occupied by air that is bled off.
 Verify that with the air vented and the water circulating, the entire system has been checked for leaks
and repairs have been made as required.
 Verify that the supplementary loop heat system (if system is equipped with this option) is operating
per the design requirements. During this operation, visual checks should be made for leaks that may have
occurred due to increased heat. Repair as required.
 Verify that the system has been opened at the lowest point for the initial blow down (making sure the
make up water is equal to the water being dumped). Continue blow down until the water leaving the drain
runs clear, but NOT less than two hours.
How many hours has your system been blown down?
____ hours
 Verify that all pumps and supplementary loop heating systems have been shut down. Reconnect the
hoses placing the water-to-refrigerant heat exchanger in the water circulating system. Note: Vents should
be open when the pumps and supplementary heat system are shut down.

UNIT STARTING AND OPERATING CONDITIONS
Operating Limits

Environment – Units are designed for indoor installation only. Never install units in areas subject
to freezing or where humidity levels could cause cabinet condensation (such as unconditioned
spaces subject to 100% outside air).

Power Supply – A voltage variation of +/– 10% of nameplate utilization voltage is acceptable.

Determination of operating limits is dependent primarily upon three factors: 1) return air
temperature. 2) water temperature, and 3) ambient temperature. When any one of these factors is
at minimum or maximum levels, the other two factors should be at normal levels to insure proper
unit operation. Extreme variations in temperature and humidity and/or corrosive water or air will
adversely affect unit performance, reliability, and service life. Consult Table 1A for operating
limits.

UNIT START UP PROCEDURE
 Turn the thermostat fan position to “ON”. Blower should start.
 Balance air flow at registers.
 Adjust all valves to their full open positions. Turn on the line power to all heat pumps.

Phone (843) 556-7272 Fax (843) 556-7487
 Room temperature should be within the minimum/maximum ranges of table 1A. During start-up
checks, loop water temperature entering the heat pump should be between 60°F [16°C] and 95°F [35°C].
 Adjust the unit thermostat to the warmest setting. Place the thermostat mode switch in the “COOL”
position. Slowly reduce thermostat setting until the compressor activates.
 Check for cool air delivery at the unit grille within a few minutes after the unit has begun to operate.
Note: Units have a five minute time delay in the control circuit.
 Verify that the compressor is on and that the water flow rate is correct by measuring pressure drop
through the heat exchanger using the P/T plugs and comparing to FHP IOM.
 Check the elevation and cleanliness of the condensate lines. Dripping may be a sign of a blocked line.
Check that the condensate trap is filled to provide a water seal.
 Check the temperature of both entering and leaving water. If temperature is within range, proceed
with the test. If temperature is outside of the operating range, check refrigerant pressures and compare to FHP
IOM. Verify correct water flow by comparing unit pressure drop across the heat exchanger versus the data
in tables in the back of FHP Installation, Operation, and Maintenance Manuals.
Heat of rejection (HR) can be calculated and compared to submittal data capacity pages. The formula for
HR for systems with water is as follows:
HR (Btuh) = TD x GPM x 500, where TD is the temperature difference between the entering and leaving
water, and GPM is the flow rate in U.S. GPM, determined by comparing the pressure drop across the heat
exchanger to tables in FHP IOM. In S.I. units, the formula is as follows: HR (kW) = TD x l/s x 4.18.
 Check air temperature drop across the air coil when compressor is operating. Air temperature drop
should be between 15°F and 25°F [8°C and 14°C].
 Turn thermostat to “OFF” position. A hissing noise indicates proper functioning of the reversing
valve.
 Allow five (5) minutes between tests for pressure to equalize before beginning heating test.
 Adjust the thermostat to the lowest setting. Place the thermostat mode switch in the “HEAT” position.
 Slowly raise the thermostat to a higher temperature until the compressor activates.
 Check for warm air delivery within a few minutes after the unit has begun to operate.
 Check the temperature of both entering and leaving water. If temperature is within range, proceed
with the test. If temperature is outside of the operating range, check refrigerant pressures and compare to FHP
IOM. Verify correct water flow by comparing unit pressure drop across the heat
exchanger versus the data in tables in FHP IOM. Heat of extraction (HE) can be calculated and
compared to submittal data capacity pages. The formula for HE for systems with water is as follows:
Thermal Resource Sales, Inc., 1038 Jenkins Road, Suite 111, Charleston, SC 29407
Phone (843) 556-7272 Fax (843) 556-7487
HE (Btuh) = TD x GPM x 500, where TD is the temperature difference between the entering and leaving
water, and GPM is the flow rate in U.S. GPM, determined by comparing the pressure drop across the heat
exchanger to tables in FHP IOM. In S.I. units, the formula is as follows: HE (kW) = TD x l/s x 4.18.
 Check air temperature rise across the air coil when compressor is operating. Air temperature rise
should be between 20°F and 30°F [11°C and 17°C].
 Check for vibration, noise, and water leaks.
 If unit fails to operate, perform troubleshooting analysis (see troubleshooting section). If the check
described fails to reveal the problem and the unit still does not operate, contact a trained service
technician to insure proper diagnosis and repair of the equipment.
 When testing is complete, set system to maintain desired comfort level.
 BE CERTAIN TO FILL OUT AND FORWARD ALL WARRANTY REGISTRATION PAPERS
TO FHP.
Note: If performance during any mode appears abnormal, refer to the FHP troubleshooting section of the
Installation, Operation and Maintenance Manual.
To obtain maximum performance, the air coil should be cleaned before start-up. A 10% solution of
dishwasher detergent and water is recommended.
