b. Requires field-supplied electrical box, North

American 1-gang box, 2-in. (51 mm) x 4-in.
(102 mm).

c. Shall have a clear colored lens.

25. Winter start kit

a. Shall contain a bypass device around the low

pressure switch.

b. Shall be required when mechanical cooling is

required down to 25°F (–4°C).

c. Shall not be required to operate on an econo-

mizer when below an outdoor ambient of 40°F

(4°C).

26. Time Guard

a. Shall prevent compressor short cycling by pro-

viding a 5-minute delay (±2 minutes) before

restarting a compressor after shutdown for any
reason.

b. One device shall be required per compressor.

27. Barometric Hood (Horizontal Economizer Appli-

cations)
Shall be required when a horizontal economizer

and barometric relief are required. Barometric
relief damper must be installed in the return air

(horizontal) duct work. This hood provides weather

protection.

28. Hinged Access Panels

a. Shall provide easy access through integrated

quarter turn latches.

b. Shall be on major panels of – filter, control box,

fan motor and compressor.

29. Display Kit for Variable Frequency Drive

a. Kit allows the ability to access the VFD control-

ler programs to provide special setup capabili-
ties and diagnostics.

b. Kit contains display module and communica-

tion cable.

c. Display Kit can be permanently installed in the

unit or used on any 2-Speed Indoor Fan Motor
System VFD controller as needed.

30. Condensate Overflow Switch:

a. This sensor and related controller monitors the

condensate level in the drain pan and shuts

down compression operation when overflow

conditions occur. It includes:

1) Indicator light - solid red (more than 10

seconds on water contact - compressors

disabled), blinking red (sensor discon-
nected).

2) 10 second delay to break - eliminates nui-

sance trips from splashing or waves in pan
(sensor needs 10 seconds of constant water

contact before tripping).

3) Disables the compressor(s) operation when

condensate plug is detected, but still allows

fans to run for Economizer.

31. Foil Faced Insulation

Throughout unit cabinet air stream, non-fibrous

and cleanable foil faced insulation is used.
