UNIT PITCH FOR CONDENSATE DRAIN
Condensate Drain Notes:
1. Unit must pitch from level towards
the condensate drain for proper drainage.
2. Confirm that condensate drains
properly from unit and that the amount of
pitch does not cause condensate leaks
inside of the unit.
3. Units are equipped with overflow
protection.
4. Be sure to leave adequate height for
the P-Trap in applications where clearance
could be an issue.
5. In some high humidity applications you
may need to apply insulative tape around
condensate drain fitting.

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most
stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is
close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse
effects occur, such as light dimming and/or shortened compressor life.
3. All fuses class RK-5.
4. Min/Max Voltage: 208/230/60 = 187-252, 460/60 = 432-504, 265/60 = 249-291
5. See Wiring Diagrams for proper 460V power.
*The external loop pump FLA is based on a maximum of three UP26-116F-230V pumps (1/2hp) for 042-072 and two pumps

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most
stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is
close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse
effects occur, such as light dimming and/or shortened compressor life.
3. All fuses class RK-5.
4. Min/Max Voltage: 208/230/60 = 187-252, 460/60 = 432-504, 265/60 = 249-291
5. See Wiring Diagrams for proper 460V power.
*The external loop pump FLA is based on a maximum of three UP26-116F-230V pumps (1/2hp) for 048-072 and two pumps
for 015-036.

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most
stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is
close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse
effects occur, such as light dimming and/or shortened compressor life.
3. All fuses class RK-5.
4. Min/Max Voltage: 208/230/60 = 187-252, 460/60 = 432-504, 265/60 = 249-291, 115/60 = 108-126
5. See Wiring Diagrams for proper 460V power.
*The external loop pump FLA is based on a maximum of three UP26-116F-230V pumps (1/2hp) for 048-072 and two pumps
for 006-036.

Notes:
1. Program B (Bold Type) is factory settings and rated CFM. CFM is controlled within 5% up to the Max ESP.
2. Max ESP includes allowance for wet coil and NO FILTER
3. Power must be off to the unit for at least 3 seconds before the ECM motor will recognize a program change.
4. Max ESP for ZS018 through ZS/ZT036 models with external electric heat is 0.8 in. w.c.; for ZS/ZT048 models it is 0.9 in. w.c.; and for ZS/ZT060 and ZS/ZT072 it is 1.1 in. w.c. Exceeding the Max ESP may result in nuisance trips of the electric heat. Thermal limits are rated at 100,000 cycles.

Notes:
1. PSC Blower motors come with 3 or 4 speed taps. To change the speed of the motor to a higher or lower speed, remove the electric box cover that is mounted on the blower. Locate the label on the motor to identify the wire color for each speed. Remove the wire nut on the existing speed and replace with the wire of selected speed.
2. Running the ZS012 at the static/SCFM points highlighted in gray, is not recommended. 3. Max ESP and speed settings for ZS models with external electric heat is shown below. Exceeding the Max ESP may result in nuisance trips of the electric heat. Thermal limits are rated at 100,000 cycles.

Filter Performance:
The blower performance data in the ECM
Blower Performance table is WITHOUT FILTER.
To determine the approximate blower
performance WITH FILTER apply the filter
pressure drop value for the filter being used or
calculate the pressure drop as follows:
6. Total ESP should be less than or equal to
Max ESP
Example: For an YT060 at an air flow of 1960
CFM calculate the filter pressure drop with a
2” MERV 11 filter and determine Total ESP and
compare to Max ESP.
Below is typical filter performance data and
should only be used as a guideline. Actual performance may vary between manufacturers.

To calculate filter pressure drop:
Applying Filter Pressure Drop to Determine Total
ESP
Example: For an YT036 at an air flow of 1420
CFM calculate the filter pressure drop with a
2” MERV 13 filter and determine Total ESP and
compare to Max ESP.
CFM = 1420
Area = 5.1 ft2
Rated Velocity = 500 fpm
Initial Resistance = 0.43 in.w.c.
Measured ESP without filter = 0.53
1. 1420 CFM ÷ 5.1 ft2 = 278 fpm
2. 278 fpm ÷ 500 fpm = 0.556
3. 0.556 x 0.43 in.w.c. = 0.24 in.w.c. = Filter Pressure Drop
4. Total ESP is 0.36 + 0.24 = 0.6 in.w.c. which is
less than the 1.1 in.w.c. Max ESP
To determine the Total ESP of a unit with the
filter in place, follow the steps below:
1. Select the filter type and determine Rated
Velocity and Initial Resistance
2. For the model being considered determine
Max ESP, CFM and Return Area
3. Determine Filter pressure drop (ΔPs) using
the equation above
4. Measure (or calculate) the ESP without filter
in place
5. Calculate Total ESP = Measured ESP + Filter

Water Flow Selection:
Example 1:
EWT = 50 oF
Model YT036, full load. Flow rate = 4.5 GPM.
Air Flow = 1380 CFM. HE = 29,400 Btuh.
TD = 29,400 / (4.5 x 485) = 13.5 oF
LWT = 50 - 13.5 = 36.5 oF
Water flow rate is acceptable.
Proper flow rate is crucial for reliable operation
of geothermal heat pumps. The performance
data shows three flow rates for each entering
water temperature (EWT column). The general
“rule of thumb” when selecting flow rates is the
following:
• Top flow rate: Open loop systems (1.5 to 2.0
gpm per ton)
• Middle flow rate: Minimum closed loop
system flow rate (2.25 to 2.50 gpm/ton)
• Bottom flow rate: Nominal (optimum)
closed loop system flow rate (3.0 gpm/ton)
Although the industry standard is adequate in
most areas of North America, it is important to
consider the application type before applying
this “rule of thumb.” Antifreeze is generally
required for all closed loop (geothermal)
applications. Extreme Southern U.S. locations
are the only exception. Open loop (well
water) systems cannot use antifreeze, and
must have enough flow rate in order to avoid
freezing conditions at the Leaving Source Water
Temperature (LWT) connection.
Example 2:
EWT = 40 oF
Model YT036, full load. Flow rate = 4.5 GPM.
Air Flow = 1380 CFM. HE = 25,300 Btuh.
TD = 25,300 / (4.5 x 485) = 11.6 oF
LWT = 40 - 11.6 = 28.4 oF
Water flow rate must be increased to avoid
freezing.
Calculations must be made for all systems
without antifreeze to determine if the top flow
rate is adequate to prevent LWT at or near
freezing conditions. The following steps should
be taken in making this calculation:
• Determine minimum EWT based upon your
geographical area.
• Go to the performance data table for the
heat pump model selected and look up
the Heat of Extraction (HE) at the “rule of
thumb” water flow rate (GPM) and at the
design Entering Air Temperature (EAT).
• Calculate the temperature difference (TD)
based upon the HE and GPM of the model.
• TD = HE / (GPM x 485).
• Calculate the LWT.
• LWT = EWT - TD.
• If the LWT is below 35-38°F, there is potential
for freezing conditions if the flow rate
or water temperature is less than ideal
conditions, and the flow rate must be
increased.

Performance Data Tables and Notes:
1. Capacity data is based on 15% (by mass)
methanol antifreeze solution (multiplier:
485).
2. Heating data is based on 70°F EAT. Cooling
data is based on 80/67°F EAT. Any condition
outside performance table(s) requires
correction factor(s).
3. Performance data accurate within ±15%.
4. Unit performance test is run without hot
water generation.
5. Desuperheater capacity is based upon 2.0
GPM water flow at 70 oF entering water
temperature.
6. Capacity data includes fan power but not
pump power and it does not reflect fan
or pump power correction for AHRI/ISO
conditions.
7. Performance data is based upon the lower
voltage of dual voltage rated units.
8. Interpolation of unit performance data is
permissible; extrapolation is not.
9. Performance data is a result of lab testing
and is not related to warranty.
10.Due to variations in installation, actual unit
performance may vary from the tabulated
data.
11.See Flow Rate Selection above for proper
application.
12.Continuous research and development
may result in a change to the current
product design and specifications without
notice.
