Hot Gas Bypass –
This options permits continuous, stable operation at capacities below
the minimum step of unloading by introducing an artificial load on the evaporator. For
models YPAL070–105, it is used on the lead circuit.
Replaceable Core Liquid Line Driers –
Liquid line driers are standard on the Series 100
single package unit. An option is provided for replaceable core driers.
Post-Coated Fins –
Optional coil-coating used on condenser coils for seashore and other
corrosive applications (with the exception of strong alkalis, oxidizers, wet bromide, chlo-
rine and fluorine in concentrations greater than 100 ppm).
Compressor Sound Blankets –
Optional compressor acoustic sound blankets are avail-
able for sound sensitive applications.
ROOF CURBS
Full Perimeter Roof Curbs –
This option includes a knock-down 14
-
inch high roof curb
for use with wood nailer (by others). Roof curb supports the entire perimeter of the unit.
Partial Perimeter Roof Curbs –
This option includes a knock-down 14
-
inch high roof
curb for use with wood nailer (by others). Roof curb supports the air handling section with
a separate support under the condenser end.
CABINET FEATURES AND OPTIONS
Double-Wall Access Doors
- Full-sized access doors provide easy access into the unit
for routine maintenance and inspection. Solid wall liners encase insulation and prevent
damage and erosion into the airstream.
Diffuser Section
– An optional diffuser section is available downstream of the supply
fan in the extended discharge plenum cabinet option. The diffuser section distributes the
airflow from the fan evenly across the downstream filter bank to optimize filter life and
effectiveness. The diffuser design is optimized to provide uniform flow at minimal airside
pressure loss.
Downstream Final Filter Rack
– An optional 90–95% efficient MERV 14 12-inch rigid
filter rack and filters is available downstream of the supply fan and diffuser segment for
hospital applications (YPAL070–105 only). A magnahelic pressure gauge is included and
visible from the outside of the unit for servicing and code compliance.
Blank Section
– An optional blank section is available downstream of the supply fan and
diffuser section.
ACCESSORIES
Filter Switch
– An optional dirty filter alarm can be provided that will provide an alarm
when the filters require cleaning.
Magnahelic Filter Pressure Gauge
– On units equipped with downstream filtration, a
magnahelic filter gauge is included and visible on the exterior of the unit. The filter gauge
measures the air pressure drop for through the rigid filter bank to indicate when replace-
ment is required.
