Accessory Description and Usage

1.

Compressor Start Assist-Capacitor/Relay Type

Start capacitor and start relay gives ‘‘hard’’ boost to compressor motor at each start-up. SUGGESTED USE: Installations where interconnecting tube length exceeds 50 ft.

Installations where outdoor design temperature exceeds 105˚F (40.6˚C).Replacement installations with hard shut-off expansion valve on indoor coil.

2.

Compressor Start Assist-PTC Type

Solid-state electrical device which gives a ‘‘soft’’ boost to the compressor at each start-up. SUGGESTED USE: Installations with marginal power supply.

Replacement installations with rapid pressure balance (RPB) expansion valve on indoor coil.

3.

Liquid Solenoid Valve (LSV)

An electrically operated shut-off valve to be installed at the outdoor or indoor unit (depending on tubing configuration) which stops and starts refrigerant liquid flow in response to compressor operation. Maintains a column of refrigerant liquid ready for action at next compressor operation cycle. Note: Compressor start assist–capacitor/relay type (Item 1) must also be used.

SUGGESTED USE: For improved system performance in air conditioners for certain combinations of indoor and outdoor units. (Refer to ARI Unitary Directory.) In certain long-line applications. (Refer to Long-Line Application Guideline).

4.

Cycle Protector

Solid-state timing device which prevents compressor rapid recycling. Control provides an approximate 5-minute delay after power to the compressor has been interrupted for any reason, including normal room thermostat cycling.

SUGGESTED USE: Installations in areas where power interruptions are frequent.Where user is likely to ‘‘play’’ with the room thermostat.All commercial installations.Installations where interconnecting tube length exceeds 50 ft.High-rise applications.

5.

Winter Start Control

* Tested combination.† Refer to TDR table prior to utilizing accessory TDR. TXV must be hard shut-off type.NOTES: 1. Ratings are net values reflecting the effects of circulating fan motor heat. Supplemental electric heat is not included.

2. Tested outdoor/indoor combinations have been tested in accordance with DOE test procedures for central air conditioners. Ratings for other combinations are determined under DOE computer simulation procedures.

3. Determine actual CFM values obtainable for your system by referring to fan performance data in fan coil or furnace coil literature.4. Minimum outdoor operating ambient in cooling mode is 55˚F (12.8˚C), maximum 125˚F (51.7˚C).

* Detailed cooling capacities are based on indoor and outdoor unit at the same elevation per ARI standard 210/240-89. If additional tubing length and/or indoor unit is located above outdoor unit, a slight variation in capacity may occur.

† Total and sensible capacities are net capacities. Blower motor heat has been subtracted.‡ Sensible capacities shown are based on 80˚F (27˚C) entering air at the indoor coil. For sensible capacities at other than 80˚F (27˚C), deduct 835

Btuh (245 kw) per 1000 CFM (480 L/S) of indoor coil air for each degree below 80˚F (27˚C), or add 835 Btuh (245 kw) per 1000 CFM (480 L/S) of indoor coil air per degree above 80˚F (27˚C).When the required data falls between the published data, interpolation may be performed.

** Unit kw is total of indoor and outdoor unit kilowatts.EWB — Entering Wet Bulb

System Design1. Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01-in. wc.2. Minimum outdoor operating air temperature without low-ambient operation accessory is 55˚F (12.8˚C).3. Maximum outdoor operating air temperature is 125˚F (51.7˚C).4. For reliable operation, unit should be level in all horizontal planes.5. Maximum elevation of indoor coil above or below base of outdoor unit is: indoor coil above = 50 ft, indoor coil below = 150 ft. (See items 6

and 7 following.)6. For interconnecting refrigerant tube lengths greater than 50 ft, consult Long-Line Application Guideline available from equipment distributor.7. Crankcase heater required when interconnecting refrigerant tube length exceeds 50 ft.8. Not more than 36 in. of refrigerant tube should be buried in the ground. If necessary to bury tubes under a sidewalk, provide a minimum 6-in.

vertical rise to the valve connections at the unit.9. Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
