York BHP024 Protected Compressor, Exclusive Coil Design, LOW Maintenance, Easy Service Access

036-21528-007-A-1205

PROTECTED COMPRESSOR

The compressor is internally protected against high pressure and temperature. This is accomplished by the simultaneous operation of high pressure relief valve and a temperature sensor which protects the compres- sor, if undesirable operating conditions occur.

EXCLUSIVE COIL DESIGN

Grooved copper tubes and enhanced aluminum fin construction improves heat transfer for maximum effi- ciency and durability.

LOW MAINTENANCE

Long life, permanently lubricated condenser and evap- orator fan motor bearings, need no annual mainte- nance. Blower assembly can be easily cleaned by the unique “Slip Track” slide-out blower assembly.

SECURED SERVICE ACCESS PORTS

Protected, externally mounted, re-usable service access ports are provided on both the high and low lines for ease of evacuating and charging the system.

EASY SERVICE ACCESS

A large, single hinged panel covers the electrical con- trols and makes servicing easy. The blower compart- ment has an additional large panel with a built-in handle tab. Removing this panel will allow the blower assembly to slide-out for easy removal for mainte- nance and ease of trouble shooting.

REPLACEMENT PARTS

The installer has no need to carry an inventory of unique parts or needs special training to replace any of the components parts for these units. All are easily obtained from Source 1 or other major part houses.

FIELD-INSTALLED ACCESSORIES

ECONOMIZER DOWN DISCHARGE / SUPPLY KIT

Modulating integrated economizer provides simulta- neous operation between the mechanical cooling and economizer operation. Independent blade design insures proper control and less than 1% leak rate. Includes hood and mesh bird screen filter integrated into the hood, dry bulb sensor and relief damper. Sepa-

rate field accessories of single enthalpy and dual enthalpy are also available.

SINGLE ENTHALPY SENSOR

Sensor replaces dry bulb sensor standard in econo- mizer kit. Provides improved economizer operation by sensing the dry bulb temperature from outdoors, plus the enthalpy content of the outdoor air.

DUAL ENTHALPY SENSOR

Additional sensor to single enthalpy sensor. Sensor selects both the return air temperature dry bulb and humidity, in conjunction with the single enthalpy, to determine the most economical mix. Single Enthalpy sensor also required.

UPGRADE PRESSURE PACKAGE

Contains screw in type High pressure, Low Pressure/ Loss of Charge switch, freeze protection switch and lockout relay. Switches are placed onto existing Schrader ports located in the unit by furnished adapt- ers. When abnormal conditions are sensed through the pressure switches, the unit will lock out, preventing any further operation until reset or problem is corrected. Package agency approved.

HAIL GUARD KIT

Kit contains protected grilles made of expanded alumi- num grilles with full perimeter 1-1/2 inch frame. Sloped hoods are also included to assure maximum protec- tion.

FILTER / FRAME KIT (SINGLE PHASE ONLY)
