Test Procedures
Operating checklist before start-up
• Review submittals for rooftop and accessories as
well as main wiring diagrams and options shipped
with the unit
• Unit is level, with sufcient clearance all round
• Duct network is correctly sized according to the unit
conguration, insulated, and water-tight
• Condensate drainage line is correctly sized,
equipped with a trap, and sloped
• Filters are in position, of correct size and quantity
and clean
• Wiring is correctly sized and connected in
accordance with wiring diagrams
• Power supply lines are protected by recommended
fuses and correctly earthed
• Thermostat is correctly wired and positioned
• Unit is checked for refrigerant charge and leaks
• Indoor and outdoor fans rotate freely and are xed
on shafts
• Supply fan rotation speed is set
• Access panels and doors are replaced to prevent air
entering and risks of injury
• When ball valve is present on the refrigerant suction
line, to check if the valve is open before starting the
unit.
WARNING! If any operating checks must be performed
with the unit operating, it is the technician’s
responsibility to recognize any possible hazards and
proceed in a safe manner. Failure to do so could result
in severe personal injury or death due to electrical shock
or contact with moving parts.
Power-up initialization
CAUTION! Before proceeding with any test procedure or
operation, make sure that crankcase heaters have been
energized for at least 8 hours.
Starting the unit in cooling mode
Before start-up, ensure that all power cables are
tightened.
Verify that the unit airow rate is adjusted.
Operating pressures
After the unit has operated in cooling mode for a short
period of time, install pressure gauges on the gauge
ports of the discharge and suction line valves.
Note: Always route refrigerant hoses through the port
hole provided and ensure that the compressor access
panel is in place.
Final installation checklist
• Are all power cables tightened?
Check torque of power cables contact !
• Is the condenser fan and indoor blower operating
correctly, i.e. correct rotation and without undue
noise?
• Are the compressors operating correctly and has the
system been checked for leaks?
• Have the voltage and running currents been checked
to determine if they are within limits?
• Have the air discharge grilles been adjusted to
balance the system?
• Has the ductwork been checked for air leaks and any
condensation?
• Has the air temperature rise been checked?
• Has the indoor airow been checked and adjusted if
necessary?
• Has the unit been checked for tubing and sheet metal
rattles or any unusual noises?
• Are all covers and panels in place and properly
fastened?
To keep the unit operating safely and efciently, the
manufacturer recommends that a qualied service
technician check the entire system at least once each
year, or more frequently if conditions warrant.
Upon power initialization, the control performs self-
diagnostic checks to insure that all internal controls
are functioning. It checks the conguration parameters
against the components connected to the system.
