2.7.3.3 Remote Water Detector

Spot Type:

A remote spot type water detector requires three

conductors to be wired to the control terminal board

within the unit electrical box. The wire insulation must

be rated at 600V. The water detector provides pig-tail

leads for splice type wire connections with twist on

connectors (wire caps). Refer to the supplied electrical

diagram for proper wire terminations.

Strip/Cable Type:

A remote strip/cable type water detector is provided

with a two conductor cable harness with a quick

connect fitting on the end. The harness mates to the

fitting on the water detector and connects it to the

control board inside the electric box. Refer to the

supplied electrical diagram for proper wire termina-

tions.

2.7.4 Air-Cooled Split Systems

The following system interconnecting field wiring

sections detail the number of conductors required for a

typical system. Additional control conductors may be

required depending on the options purchased with the

equipment. Refer to the supplied electrical diagram to

determine the total number of interconnecting conduc-

tors required for your system. It is important to note

that the control transformer(s) supplied with the

equipment have been sized and selected based upon

the expected loads for each system.

CAUTION

Do not connect any additional loads to the sys-

tem control transformers. Connecting additional

loads to the factory supplied control

transformer(s) may result in overloading of the

transformer.

NOTE

All wiring must be provided in accordance with

local and national electrical code requirements

for Class 2 circuits.

2.7.4.1 Remote Condenser (See Figure 9)

Systems equipped with a remote condenser require

field wiring between the evaporator system and the

remote condenser. Refer to the supplied electrical

schematic and the wiring diagram supplied with the

condenser (typically located in the condenser electric

box). The installer must provide main power wiring to

the main power distribution block located within the

remote condenser control box. A separate equipment

ground lug is provided within the electrical box for

termination of the earth ground wire.

The installer must also wire two control conductors

from the terminal board within the evaporator unit to

the control terminal board within the remote condenser

control box. Refer to the supplied electrical diagram for

proper wire terminations.

2.7.4.2 Remote Condensing Unit

(See Figure 10 and 11)

Systems equipped with a remote condensing unit

require field wiring between the evaporator system and

the remote condenser unit. The number of conductors

required between the two systems varies based upon

the number of options provided. A single stage cooling

system typically requires three conductors. Refer to

the supplied electrical diagram(s) to determine the

exact amount of field wires and proper wire termina-

tions required for your specific unit.

2.7.5 Water/Glycol Systems (See Figure 12)

The following system interconnecting field wiring

sections detail the number of conductors required for a

typical system. Additional control conductors may be

required depending on the options purchased with the

equipment. Refer to the supplied electrical diagram to

determine the total number of interconnecting conduc-

tors required for your system. It is important to note

that the control transformer(s) supplied with the

equipment have been sized and selected based upon

the expected loads for each system.

CAUTION

Do not connect any additional loads to the sys-

tem control transformers. Connecting additional

loads to the factory supplied control

transformer(s) may result in overloading of the

transformer.

NOTE

All wiring must be provided in accordance with

local and national electrical code requirements

for Class 2 circuits.

Systems equipped with a glycol-cooled system/pump

package require field wiring between the glycol unit and

pump package. The installer must wire two control

conductors from the terminal board within the glycol unit

to the pump package electrical box. Refer to the supplied

electrical schematic for proper wire terminations.
