1.
The installer SHALL check available power to make certain
it matches the unit (Name Plate Rating) and that constant
voltage can be maintained to the unit. Unsatisfactory
performance would otherwise result. The local power
company should be contacted on any problems or questions
concerning power supply.
2.
Install a line service disconnect switch within sight of the
condensing unit. The line voltage service wiring for the
condensing unit should include a fused disconnect switch.
3.
Use correct wire size and fuse size. To ensure that adequate
voltage will be available at the condensing unit, the line
voltage service wiring MUST be of adequate size. Minimum
recommended wire ampacities and maximum fuse sizes are
listed on the unit name plate.
4.
Two holes are provided in the control box.
a. One is for the connection of the line voltage conduit
or cable. The hole is sized for
3
/
4
" conduit.
b. One is for low-voltage wiring. (Refer to the wiring
diagram attached to electrical box cover for
connection.)
5.
Be sure to ground the condensing unit by securing the
ground wire to the grounding lug inside the control box.
6.
Be sure to follow National Electrical Code and all local
codes.

When replacing an existing system, it is mandatory that a liquid line filter dryer (if not provided with the condensing unit) and a suction line
filter, conforming to the dryer selection chart below, be installed in the new system if any of the original refrigerant-bearing components are
to be used in the new installation. This is to assure that any contaminants left in the original components will not harm the new system. If
any other evaporator coils other than those manufactured or approved by our company are used in the installation, THE CLAIMED
PERFORMANCE AND WARRANTY WILL BE VOID without written notification and approval of such coils by our company.

Selection of dryers smaller than recommended will cause unsatisfactory pollution protection, excessive refrigerant charge and pressure drop.
High pressure drops will result in reduced system capacities, higher system operating cost and increased failure rate.
