Commercial Glasswasher Installation & Operation Manual
Printed in USA 7
WARNING: If water pressure exceeds 50 psi, pressure reducing valve (PRV) is recommended. The
supply water to the PKHT24 must be a minimum of 140°F at 24 psi (Pounds per Square Inch) with a 6
gpm (Gallons Per Minute) fl ow rate and 60 gph (Gallons Per Hour) recovery rate. The pipe supplying
the water must be ½” minimum. The plumbing connection is located at the back of the machine. (See
specifi cation sheet on page 4).
The PKHT24 may be supplied with an optional drain pump for elevated drains. For fl oor gravity drain
applications, the drain pump should not be used and a good commercial grade hose needs to be
connected to the discharge side of the diverter valve (drain valve) and run to the fl oor drain. If a drain
pump is used with a fl oor drain, the drain hose must rise 12 to 16” before dropping to the fl oor drain (to
reduce any chance of the pump cavitations).
WARNING: Water hardness greater than 3 grains per gallon requires a water softener to prevent
damage to heating elements (scale build- up) and booster tank rinse fl ow restriction. Rinse fl ow
restriction will cause the booster tank to expand and contract causing metal fl ex, which will eventually
crack the tank.
