FEATURES/BENEFITS

This unit is a packaged heat pump for manufactured housing,
residential, and light commercial applications. Factory assembled
packageis a compact, horizontal supply and return unit, combining
easy installation and maintenance with efficient performance.

EASY TO INSTALL—The units are lightweight, compact single
package units that are easy to handle. Every size unit has an
identical 32 by 51--in. (813 by 1295 mm) footprint to make job
site planning simple. The efficient design uses less sheet metal and
makes the PH4Z units lighter than competitive units. The unit can
be easily positioned on the job site with the hand--holds built into
the unit basepan.

AERODYNAMIC FAN BLADE DESIGN reduces overall sound
by up to 3dBA; low as 73dBA.

SERVICE ACCESS—The units are designed to be serviced from
both front and side. Routine maintenance tasks, such as coil
cleaning, are sped up with the multiple side panels design.

CORROSION PROOF UNIT BASE—The unit features a tough,
high--tech, single--piece composite material unit base with an
integrated drain. The composite material eliminates the potential
problem of rust and premature replacement which are common
with standard metal pans. Each unit base is sloped to eliminate
standing water. This feature minimizes the amount of standing
water inside the unit, which limits mold and mildew growth.

DURABLE STEEL CABINET—The watertight construction
and corrosion--resistant finish will keep it looking like new for
years. A specialized paint treatment process ensures quality
protection against the elements. A compact, low--profile design
utilizes a louvered coil enclosure for maximum protection against
hail damage and vandalism.

SCROLL COMPRESSORS—Each unit comes standard with a
scroll compressor. Each scroll compressor is hermetically sealed
against contamination to help promote longer life and dependable
operation. All scroll compressors have internal high--pressure and
overcurrent protection.

COIL EFFICIENCY—Indoor and outdoor coils are computer
designed for optimum heat transfer and cooling efficiency.

DEFROST SYSTEM—The system provides time/
temperature--based defrost cycles to maintain unit efficiency. This
highly reliable system monitors coil temperature and initiates a
defrost cycle only if it is required. The defrost cycle ends as soon as
defrosting is complete.

ACCESSORY ELECTRIC HEATERS —A variety of accessory
electric heaters are available for these units. These heaters are
comprised of a separate heater module mounted on the blower inlet
and remote mounted controls located in the unit control box.
Single point electrical connections are provided for powering both
the heater and the unit.

START COLLARS—Start collars are provided with each unit to
provide easy connection to the structure ductwork.

DEPENDABLE COMPONENTS—Direct--drive, multi--speed
blower motor is standard on all models.

DIRECT--DRIVE, PSC OUTDOOR--FAN MOTORS are
designed to help reduce energy consumption and provide for
cooling operation down to 40F(4.4C). It’s high efficiency design
ensures high performance with most duct systems.

Compressor Start Kit assists compressor start- --up by providing
additional starting torque.

Thermostats provide control for the system heating and cooling
functions.

Crankcase Heater provides anti ---floodback protection for low --­load cooling applications.

Low Ambient Kit (Motormaster II Control) allows the use of mech­anical cooling down to outdoor temperatures as low as 0°F
( ---18° C) when properly installed.

Automatically prevents the compressor from restarting for at least
4 minutes and 45 seconds after shutdown of the compressor. Not
required when a corporate programmable thermostat is applied.

SELECTION PROCEDURE

I. DETERMINE COOLING AND HEATING
REQUIREMENTS AT DESIGN CONDITIONS

Given:

Required Cooling Capacity (TC 28,000 Btuh...........

Sensible Heat Capacity (SHC) 20,500 Btuh............

Required Heating Capacity 28,550 Btuh...............

Outdoor Entering--Air Temperature 95F(35C)........

Outdoor--Air Winter Design Temperature 20F(--6.7C)..

Indoor--Air Winter Design Temperature ............70F

(21.1C)

Indoor Entering--Air Temperature . . . . . . . . . . . . . 80F (26.7C)

edb, 67F ewb (19.4C)

Indoor--Air Quantity ........................1000 CFM

ExternalStaticPressure ...................0.20IN.W.C.

ElectricalCharacteristics(V--Ph--Hz)..........230--1--60

edb — entering dry bulb
ewb — entering wet bulb

The required heating capacity is 28,550 Btuh. Therefore, 11,810
Btuh (28,550 -- 16,740) additional electric heat is required.

Determine additional electric heat capacity in kW.

11,810 Btuh

3414 Btuh/kW

3.46 kW of heat required

=

Enter the Accessory Electric Heater Usage table on page 4 for
208/240v. single--phase, 030 unit. The 5--kW heater at 240v most
closely satisfies the heating required. To calculate kW at 230v,
multiply the heater kW by multiplication factor 0.92 found in the
Multiplication Factors table on page 4.

5 kW x 0.92 = 4.6 kW

4.6 x 3414 = 15,704 Btuh
To calculate kW at 208 v, see Multiplication Factors table on page

4.
Total unit heating capacity is 32,444 Btuh (16,740 +15,704).

II. SELECT UNIT BASED ON REQUIRED COOLING
CAPACITY

Enter Cooling Capacities table at condenser entering temperature
of 95F(35C), indoor air entering at 1000 cfm and 67F (19.4C)
ewb (entering wet bulb). The 030 unit will provide a total cooling
capacity of 28,800 Btuh and a sensible heat capacity of 21,600
Btuh.

For indoor--air temperature other than 80F edb (entering dry
bulb), calculate sensible heat capacity correction, as required, using
the formula found in Note 3 following the cooling capacities
tables.

NOTE: Unit ratings are net capacities.

III. SELECT ELECTRIC HEAT

Enter the 030 Heating Capacities table at 1000 CFM. At 70F
(21.1C) return indoor air and 20F(--6.7C) air entering outdoor
coil, the integrated heating capacity is 16,740 Btuh. (Select
integrated heating capacity value since deductions for outdoor--coil
frost and defrosting have already been made. No correction is
required.)

IV. DETERMINE FAN SPEED AND POWER
REQUIREMENTS AT DESIGN CONDITIONS

Before entering the air delivery tables, calculate the total static
pressure required. From the given, the Accessory Electric Heat
Pressure Drop table, and the Filter Pressure Drop table, find:

External static pressure 0.20 IN. W.C.
Filter 0.09 IN. W.C.
Electric heat 0.04

IN. W.C.

Total static pressure 0.33 IN. W.C.

Enter the table for Dry Coil Air Delivery — Horizontal Discharge
at 1000 CFM and 230v high speed. The blower will deliver 1036
CFM @ 0.40 IN W.C. static pressure. This will adequately handle
job requirements.
