Installation Instructions

TIME- - DELAY

RELAY KIT

NOTE: Read the entire instruction before beginning the

installation.

INTRODUCTION

The Time-- Delay Relay permits the indoor fan to briefly continue

to operate and provide additional cooling after the compressor

cycles off.

SAFETY CONSIDERATIONS

Installing and servicing air conditioning equipment can be

hazardous due to system pressure and electrical components.

Only trained personnel should install or service air conditioning

equipment.

Untrained personnel can perform basic maintenance functions,

such as cleaning coils and cleaning and replacing filters. All other

operations should be performed by trained service personnel.

When working on air conditioning equipment, observe

precautions in the literature, and on tags and labels attached to the

unit.

Follow all safety codes. Wear safety glasses and work gloves. Use

a quenching cloth for brazing operations. Have a fire extinguisher

available.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal

injury or death.

Before beginning any modification be sure the main

electrical disconnect is in the OFF position. TAG SWITCH

WITH A SUITABLE WARNING LABEL.

WARNING

INSTALLATION

ELECTRICAL OPERATION HAZARD

Failure to follow this caution may result in personal injury.

Before installing this kit, be sure high-- and low--voltage

electrical power to indoor section is disconnected.

CAUTION

1. Using screws provided, mount time--delay relay to fan coil

or furnace cabinet. Position time--delay relay in convenient

place so that wires will be close to connection point. Drill

0.125 in. (use 1/8 drill size) screw holes into cabinet.

NOTE: Check to make sure no components inside cabinet are

within drilling range.

2. Paint edges of screw holes to resist rust. Install mounting

screws through time-- delay relay and into screw holes.

Tighten screws securely but do not overtighten.

ELECTRICAL OPERATION HAZARD

Failure to follow this caution may result in personal injury

or equipment damage.

The time--delay relay and low-- voltage wiring should be

physically separated from high-- voltage components and

wiring.

CAUTION

3. Refer to Fig. 1 for wiring connections.

4. Connect red wire from time--delay relay to terminal R on

low--voltage terminal board in fan coil or furnace.

5. Connect brown wire from time-- delay relay to terminal C

on low--voltage terminal board.

6. Splice wire from thermostat terminal G to black wire from

time--delay relay.

7. Connect orange wire from time--delay relay to terminal G

on low--voltage terminal board.

8. Affix wiring label next to indoor unit wiring label.

9. Check all connections. Turn on electrical power.

10. Affix caution label on indoor unit access panel to electrical

controls.

11. To check function of system, set thermostat to operate in

cooling mode. With system “calling for cooling” run for

minimum of 5 minutes, then slowly move cooling lever

on thermostat to higher setting to satisfy thermostat. Once

the thermostat is satisfied, the indoor fan will continue to

run approximately 90 seconds, then shut off.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage.

This accessory package includes an adhesive--backed

warning sticker. Affix this sticker prominently to fan coil or

furnace after installation.
