Attaching horizontal ductwork to unit
All conditioned air ductwork should be insulated to minimize
heating and cooling duct losses. Use a minimum of two (2)
inches of insulation with a vapor barrier. The outside ductwork
must be weatherproofed between the unit and the building.
When attaching ductwork to a horizontal unit, provide a flexible
watertight connection to prevent noise transmission from the
unit to the ducts. The flexible connection must be indoors and
made out of heavy canvas.
Attaching downflow ductwork to roof curb
Supply and return air flanges are provided on the roof curb for
easy duct installation. All ductwork must be run and attached to
the curb before the unit is set into place.
Follow these guidelines for ductwork construction:
Connections to the unit should be made with three-inch canvas
connectors to minimize noise and vibration transmission.
Elbows with turning vanes or splitters are recommended to
minimize air noise and resistance.

Minutes delay for the compressor start-up
At the beginning of energizing or after the stop of the
compressor, 3-minutes delay will be taken to start the
compressor.
When switchover between cooling/heating mode, the
compressor stops automatically.
Compressor discharge gas temperature switch protection
When compressor discharge gas temperature
discharge gas temperature switch will be closed. At the same
time, the corresponding compressor will be shut off. The
ON/OFF signal and high-pressure protection signal should be
connected together.
Reverse phase protection relay
The reverse phase protection relay will make the compressor
not start, when the power source is incorrectly connected.
The checking of phase’ order is just carried out at the first time
of electrifying. If malfunction happens then the checking will be
going on until the order of phase is right, and the E0 will be
displayed on the board. If there is no problem in the first
checking, then it will be omitted.
High pressure and low pressure protection
The ON/OFF of high pressure and low pressure will be
installed separately around inlet pipe, and both are connected
to Main Control Board. The ON/OFF of high pressure will be
off when the pressure is higher than 425Psi. The ON/OFF of
low pressure will be off when lower than 7Psi.
