Step 6 — Provide for Condensate Disposal

NOTE: Ensure that condensate-water disposal methods comply with local codes, restrictions, and practices.

The 604D--A units dispose of condensate through a 3/4 in. NPT female fitting that exits on the compressor end of the unit. Condensate water can be drained directly onto the roof in rooftop installations (where permitted) or onto a gravel apron in ground level installations. Install a field-supplied 2-in. (51 mm) condensate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the trap is at least 1 in. (25

mm)lower than the drain-pan condensate connection to prevent the pan from overflowing. Prime the trap with water. When using a gravel apron, make sure it slopes away from the unit.

If the installation requires draining the condensate water away from the unit, install a field-supplied 2 -in. (51mm) trap at the condensate connection to ensure proper drainage. Condensate trap is available as an accessory or is field-supplied. Make sure that the outlet of the trap is at least 1 in. (25 mm) lower than the unit drain-pan condensate connection to prevent the pan from overflowing. Connect a drain trough using a minimum of field-supplied 3/4-in. PVC or field-supplied 3/4-in. copper pipe at outlet end of the 2-in. (51 mm) trap. (See Fig. 10) Do not

High-Voltage Connections

The unit must have a separate electrical service with a field-supplied, waterproof disconnect switch mounted at, or within sight from the unit. Refer to the unit rating plate, NEC and local codes for maximum fuse/circuit breaker size and minimum circuit amps (ampacity) for wire sizing.

The field-supplied disconnect may be mounted on the unit over the high-voltage inlet hole when the standard power and low-voltage entry points are used. See Fig. 2 and 3 for acceptable location. Remove high voltage knockout.

See unit wiring label (Fig. 11-13) and Fig. 9 for reference when making high voltage connections. Proceed as follows to complete the high-voltage connections to the unit.

Single phase units:

1.Run the high-voltage (L1, L2) and ground lead into the control box.

2.Connect ground lead to chassis ground connection.

3.Locate the black and yellow wires connected to the line side of the contactor.

undersize the tube. Pitch the drain trough downward at a slope of at least 1 in. (25 mm) every 10 ft (3 m) of horizontal run. Be sure to check the drain trough for leaks. Prime the trap at the beginning of the cooling season start-up.

UNIT COMPONENT DAMAGE HAZARD

Failure to follow this caution may result in damage to the unit being installed.

1.

Make all electrical connections in accordance with NEC

 

NFPA 70 (latest edition) and local electrical codes

 

governing such wiring. In Canada, all electrical

 

connections must be in accordance with CSA standard

 

C22.1 Canadian Electrical Code Part 1 and applicable

 

local codes. Refer to unit wiring diagram.

2.

Use only copper conductor for connections between

 

field-supplied electrical disconnect switch and unit. DO

3.

Be sure that high-voltage power to unit is within

 

operating voltage range indicated on unit rating plate. On

 

3-phase units, ensure phases are balanced within 2

 

percent. Consult local power company for correction of

 

improper voltage and/or phase imbalance.

4.

Do not damage internal components when drilling

 

through any panel to mount electrical hardware, conduit,

 

etc.

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

The unit cabinet must have an uninterrupted, unbroken electrical ground. This ground may consist of an electrical wire connected to the unit ground screw in the control compartment, or conduit approved for electrical ground when installed in accordance with NEC,NFPA 70 National Fire Protection Association (latest edition) (in Canada, Canadian Electrical Code CSA C22.1) and local electrical codes.
