WARNING
•
Wires must be properly sized according to the
NEC/NFPA 70, CEC and all prevailing codes,
ordinances and standards.
•
•
•
•
•
•
All conductors must be installed with a strain
relief eliminating stress on the wire following
installation which may result in wire damage
and/or overheating with a potential for re.
CAUTION
•
When connecting with RS 485 communication
to the outdoor unit, shielded wire must be used
and grounded at one end only.
When using shielded wire the cable should be
grounded at one end to reduce EMI.
Read this manual carefully before installing or
operating your new air conditioning unit.Make
sure to save this manual for future reference.
Wear appropriate personal protection equipment
(PPE) when installing or servicing.

Installation Method
2.
Mount the back plate of the 24V INTERFACE
KIT
Mount 24V INTERFACE KIT vertically, and
folding in on, fasten the back plate to the
wall with 3 screws (M4x20) and anchors.
Minimum free space required around the
kit is 7" (180 mm).
Place the unit on a at surface. Be careful not
to distort the back plate of the 24V INTERFACE
KIT by over tightening the screws.
NOTE:
•
•
When installed vertically, the direction of the
arrow must be up.

Key Considerations
•
Power switch on new board is changed.
Indoor unit power switch setting, ENC-1 must
be changed to the proper motor wattage:
Eg. 36K = 8 48K = 9
•
•
The following steps should be taken when
using this device with a Hi wall
(9K-36K Btu/hr) Cassette, Console, Duct,
Floor Ceiling (9K - 24K Btu/hr).
•
•
When the indoor air handler or furnace has
its own 24 vac transformer, you must
disconnect all four wires of the kit transformer.
The following steps should be taken when
using this device with a conventional
central air conditioning unit:
* Indoor coil metering device must be removed.
* 24V transformer in the interface module must
be disconnected.
* Refrigerant charge amount may need to be
adjusted，depending on the pipe size and
length，see outdoor recharge instruction.
* The maximum air ow should not exceed
400 CFM/Ton.
•
Suction and liquid refrigerant lines must be
properly insulated to prevent condensation
and energy loss.
•
You must remove the expansion device from
an indoor evaporator coil as the refrigerant is
controlled by a metering device in the
outdoor unit.
