Construction. PSU fan convectors are constructed of an internal “Heatpack” section mounted to a well designed back chassis. All components
are then enclosed under a shroud (cover) which is made of high grade zinc coated steel painted with a dove grey baked enamel nish.
“Heatpack” Section. A uniquely designed internal component consisting of the coil, fan & motor assembly and all controls integrally mounted.
Heat Exchanger. A highly ecient, headered coil, made of copper tubes expanded into smooth aluminum plate ns (10 FPI), tested at 300 PSI,
and sealed for quality. The heat exchanger is positioned in each PSU unit for maximum heat transfer over the coil.
Fan and Motor Assembly. High spec tangential EBM fan and motor assembly consists of high static fan wheel and scroll, detachable motor,
replaceable “easy glide” sleeve bearings, and the fan and motor cut out are protected to UL specications. This fan and motor assembly is
designed to run whisper quiet without vibration.
Controls. All PSU units have integral two speed, max.-o-min., and switches (optional wall mounted fan speed controller is available). The LTC –
low limit aquastat is also a high spec item with a close tolerance designed to close on a rise to 110°F+/- 3°F and open at 90°F+/-3°F.
Water Connections. Supply & return connections are 1⁄2" (PSU 10, 15 & 23) or ¾” (PSU 30 & 40) sweat connections located on the left hand side
of the unit as you face the grille. A water vent with wide convenient screwdriver slot is accessible on the left of the unit underneath the cover.
Electrical Connections. (PSU 10, 15 & 23)120/60/1 power supply is required. The cover shroud (i.e. the cover) must be removed to bleed the
unit. (PSU 30 & 40) 120/60/1 power supply is required. All that’s required is to knock out the junction box hole you want to use and wire to the
L1 and L2 leads. There is a convenient one screw access plate on the top of the unit to get at the ground.

NOTES:
1. PSU 10, 15 & 23 capacities based on 2 gpm correction factors for: .5 gpm = .80;
1.5 gpm = .96; 2.5 gpm = 1.07; 3 gpm = 1.12; and 5 gpm = 1.23. PSU 30 & 40
capacities based on 3 gpm correction factors for: 1 gpm = .85; 5 gpm = 1.18.
2. Aquastat set to close on a rise to 110°F and to open on a drop to 90°F.
3. It is recommended that selections be made at low speed at the desired water
temperature.
