Humidistat
To be used in conjunction with one of the dehumidication options. Humidistat to be wall mounted and capable of providing
solid state input to unit controls to enable/disable dehumidication features.
Hose Kits
Two re-rated exible hoses with ASTM ratings of Flame Spread 25, Fuel Contribution 25 and Smoke Density 50 for con-
nection to unit and eld piping. Hose shall be covered with stainless steel braiding to prevent damage.
Condensate Hose Kits
• Optional plastic hose including ttings
• Optional re-rated, braided steel hose including ttings
Valve Options
• Optional 2-way, Normally Open (N.O.) or Normally Closed (N.C.) motorized valves.
• Optional 2-way, mechanical ball valve
Automatic Flow Hose Kit
The automatic ow hose kit shall include an automatic ow control valve, two ball valves, two exible hoses, a high ow
Y-strainer, and may include a strainer blow-down and various other accessories. The automatic ow control valve shall be
factory set to a rated ow, and shall automatically control the ow to within 10% of the rated value over a 40 to 1 differen-
tial pressure, operating range (2 to 80 PSID). Operational temperature shall be rated from uid freezing, to 225°F. The valve
body shall be constructed from hot forged brass UNS C37700 per ASTM B-283 latest revision.
Stand for Vertical Units
A steel, corrosion resistant stand shall be offered to be used to raise the vertical WSHP’s above oor level. Height shall be
xed and not selectable.
Replacement Filters
2-inch MERV 8, 4 inch MERV 13, and 2-inch disposable lters shall be available as direct replacement to factory-installed lters.
Electric Heat Coils
An optional 5, 10, 15, or 20 kW eld installed duct heater shall be available. These heaters will require a eld provided power
source. 15 and 20 kW heaters shall be 2-stage.

Appendix-B
Note: ECM motors on 460/60/3 volt units require a 265 volt power supply. Both a hot AND a neutral wire are required to
obtain proper fan motor voltage. Therefore, 4-wires with a wye type wiring arrangement is required.
