Accessory description and usage (Listed alphabetically) continued
16. Thermostatic Expansion Valve (TXV) — Bi-Flow
A modulating flow control valve which meters refrigerant liquid flow rate into the evaporator in response to the superheat of the refrigerant gas leaving the evaporator. Kit includes
valve, adapter tubes, external equalizer tube.
SUGGESTED USE:
A TXV specifically designed for Puron refrigerant is required for all installations.
17. Time-Delay Relay
An SPST delay relay which briefly continues operation of the indoor blower motor to provide additional cooling after the compressor cycles off.
SUGGESTED USE:
For improved efficiency ratings for certain combinations of indoor and outdoor units. (Refer to ARI Unitary Directory.)
Required for use on all zoning systems.
18. Unit Risers
Six in. tall plastic rails that are used to elevate outdoor units above mounting pad. The risers are adjustable from 24- to 34-in. long.
SUGGESTED USE:
Heat pump installations in light to moderate snowfall areas.
Coastal installations.
Windy areas or where debris can circulate.
Rooftop installations.
Electrical data
* Permissible limits of the voltage range at which unit will operate satisfactorily. Operation outside these limits may result in unit failure.
† Time-delay fuse or Circuit Breaker.
‡ Length shown is as measured 1 way along the wire path between the unit and the service panel for voltage drop not to exceed 2%.
** If wire is applied at ambient greater than 30°C (86°F), consult Table 310-16 of the NEC (ANSI/NFPA 70). The ampacity of nonmetallic-sheathed cable (NM),
trade name ROMEX, shall be that of 60°C (140°F) conductors, per the NEC (ANSI/NFPA 70) Article 336-26.
If other than uncoated (non-plated), 60° or 75°C (140° or 167°F) insulation, copper wire (solid wire for 10 AWG and smaller, stranded wire for larger than
10 AWG) is used, consult applicable tables of the NEC (ANSI/NFPA 70).
NOTE: Control circuit is 24v on all units and requires external power source. Copper wire must be used from service disconnect to unit. All motors/compressors
contain internal overload protection.
Sound power
NOTE: Tested in accordance with ARI Standard 270-95. (Not listed with ARI).
