STARTUP
W A R N I N G !
The machine should be started up only by authorized and qualified personnel.
6.1. Preliminary Verifications
•
Check that the electrical connection has been implemented correctly and that all clamps
are tightly fastened.
•
Check that the voltage on the RST clamps is 460 V ± 5% (line voltage should show
277V +/- 3%)). If the voltage is subject to frequent variations, contact Lync technical
services or your local rep for the selection of relevant protections.
•
Check that the pressure in the refrigerant circuits is shown on the control display.
•
Check for refrigerant fluid leaks by using a leak detector intended for R-744 refrigerant.
•
Check the correct power supply of the guard resistances.
W A R N I N G
The resistances must be inserted at least 12 hours before the initial start- up and takes place
automatically when the master switch is closed.
To check the correct functioning of the resistances, check that the lower part of the compressors
is hot and in all cases is at a temperature of 5-8°F (10-15°C) over the environment temperature
.
•
Check that the hydraulic connections have been made correctly, respecting the
indications on the input/output plates on the machine
.
•
Check that the hydraulic system has been bled, thereby eliminating all residual air and
loaded gradually, opening the vent devices in the upper part, which the installer would
have set up together with an expansion tank of adequate capacity
.
A T T E N T I O N
Before starting-up, verify that all the closing panels of the unit are in place and secured.
W A R N I N G
All the units are pre-loaded with refrigerant gas, so the refrigerant circuit is pressurized.
There is no need to charge the refrigerant circuit before unit start up.
6.2. Verifications During Operation
•
Check that the sequence of the phases is correct
.
This can be verified by making sure
that the fans are rotating in the correct direction (see Section 5.3). The fan should be
pulling air in the side of the heat pump and directing it up out the top of the unit.
•
Check that gas cooler inlet water temperature is near the electronic control setpoint
.
