PROTECTION PACKAGE

A.A check filter switch operates on differential pressure and indicates when the airflow pressure drop has in- creased past a user defined setpoint (field adjustable from 0.05 - 5 inches of water; factory set at 0.25 inches). Factory wire leads are provided in the control box for wiring to a re- mote 24V indicator, see the unit wiring label.

B.A phase loss monitor protects against phase loss, low voltage and phase reversal. The switch automatically shuts off power to the units control circuit if one of the above con- ditions is detected and will automatically reset upon correc- tion of the problem. The sensitivity is field adjustable and has a visual LED indication of its operational status. Factory wire leads are provided in the control box for wiring to a re- mote 24V indicator, see the unit wiring label.

C.A condensate overflow switch shuts down and locks out the unit prior to overflow of the evaporator condensate pan. To reset the lockout, power must be reset at the unit and the fault condition must be cleared before proper operation can be restored. It requires periodic cleaning and maintenance. Factory wire leads are provided in the control box for wiring to a remote 24V indicator, see the unit wiring label.

To modify the condensate overflow switch system to act as a auto-reset safety only requires removing one wire. Re- move the wire that leads from the overflow switch to the lockout relay. See unit wiring diagram for wire number and details

INSTALLATION PACKAGE

A.Disconnect Switch

For units with gas heat or factory installed electric heat this package includes a: HACR Molded Case Circuit Breaker that doubles as a disconnect switch while also providing unit mounted over-current and short circuit protection.

For units shipped as cooling only or utilizing field mounted electric heat kits this package includes a: Non-Fused Molded Case Disconnect Switch. This switch is sized for the largest electric heat kit available from York for each model size and voltage. This switch provides a unit

mounted switch for disconnecting power during routine maintenance or service, but does not provide over-current or short circuit protection for the unit's power supply.

NOTE:This breaker is not intended to replace any additional circuit protection required by any local or national code.

WARNING: The breaker shipped with dual voltage (208/230V) 15 ton and 20 ton models utilizing 36 or 72kW elec- tric heat is sized only for 240V service. These models: DHE180E03625, DHE180E07225, DHE240E02625 and DHE2400E07225, require a 208V rated breaker when powered by 208V serv- ice. A kit is available to provide a breaker properly sized for 208V applications that mounts in the same location as the factory mounted breaker.

B.Non-powered 120V G.F.C.I. duplex outlet is rated at 20 Amps for U.S. locations and 15 Amps for Canadian loca- tions (Requires separate 120V power be supplied to the unit).

CABINET PACKAGE

A.Tool-less, hinged filter door allows for easy access and maintenance.

NOTE: Knobs are shipped separately within the unit to prevent shipping damage. These must be field installed for tool- less operation.

B.Tool-less blower and control panels (not hinged) allows for easy access and maintenance.

NOTE: Knobs are shipped separately within the unit to prevent shipping damage. These must be field installed for tool- less operation.

C.Condenser coil grill guards to protect the coil surface from damage.
