The PKHT24 is a hot water sanitizing, single rack, undercounter glasswasher. It is a stand-alone machine featuring a self-contained booster heater. The only external connections necessary are power supply, water supply, drainpipe, and optional chemical dispensers. The machine uses re-circulated wash water and fresh water final-rinse.
Operation of the PKHT24 is extremely user friendly. To initially fill the machine each day, push the switch marked "FILL". The machine is full when water begins to flow into the scrap tray. The booster tank heater will maintain the wash water temperature at 155° F. The booster heater will produce a minimum of 180° F final rinse water each cycle.
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) flow rate and 60 gph (Gallons Per Hour) recovery rate. The pipe supplying the water must be a minimum of a 1/2". The plumbing connection is located at the back of the machine. (See specification sheet). The drain is a 1" barbed fitting on the back of the machine for easy attachment of your drain hose.
This manual provides a complete reference guide to the PKHT24. The first section explains how the machine is packaged and what to look for when receiving the machine. This manual explains how to install and set up the machine for use. Requirements are given for plumbing, wiring, and space considerations. These are always taken into consideration by our well-trained sales representatives prior to the order being placed. In the manual, guidance is also given for installation to ensure that the machine will be able to run at optimum conditions.
The machine's functions are mostly automatic and take little training to put into full operation. The Operation section of the manual may be used for instruction and procedures when required. We make this portion of the manual easy to understand so that all levels of operators are able to understand the machine's operation. The Operation section also includes diagnostic considerations for the machine when problems occur.
We are committed to providing the best products and customer service, and we welcome your feedback.

OPERATIONAL CYCLE
The PKHT24 operational cycle has a total cycle time of 2 minutes (120 seconds). The Timing Diagram and the steps listed below detail the individual functions that are executed during each operational cycle.

- With the machine powered up, toggling the START switch begins a cycle.
a) Toggling the START switch energizes both the Cam Timer motor and the Instant Start Relay. The Instant Start Relay latches ON the power to the Cam Timer motor so that the START switch can be released a moment after it has been toggled without the Cam Timer motor losing power.
b) After about 1.5 seconds the Cam Timer's first cam — the Cam Timer Motor Cam — latches ON the power to the Cam Timer motor and drops out the Instant Start Relay. The Cam Timer motor continues to run for a total of 2 minutes, at which time it switches OFF — resetting the Cam Timer — and waits for the next START command.
-
The Cam Timer's third cam controls the Wash Pump. The Wash Pump comes ON about 3 seconds into the Operational Cycle and continues to run for 94 seconds. This 94-second period is the Wash Cycle.
-
At the same time that the Wash Pump comes ON the Cam Timer's fourth cam powers ON the Optional Drain Pump — if one is present — and keeps it running for about 7 seconds before powering OFF. This cam turns ON again midway through the Rinse Cycle and stays ON for 10 seconds, turning OFF 2 seconds after the Rinse Cycle has completed.
-
About 3 seconds after the Wash Cycle has completed the Cam Timer's second cam, which controls the Rinse Cycle, turns ON — energizing the Water Solenoid — and stays ON for 16 seconds. This 16-second period is the Rinse Cycle.
-
When the Cam Timer assembly approaches the final rinse portion of the cycle, the "Safe-T-Temp" sixth micro switch will pause Cam Timer assembly if the booster heater has not reached 180 degrees. The machine will remain in wash cycle mode until 180-degree rinse temperature is reached, and at this time the Cam Timer will advance automatically into the rinse cycle and dispense 180 degrees rinse water over the dishes.
GETTING STARTED
Receiving and Installation
The glasswasher is shipped from the factory in a corrugated box on a wooden pallet. The installation guidelines give a systematic procedure for setting up the machine.
Start by removing the packaging material. Unwrap the machine and check for the following component parts:
The Wash Tank Scrap Screen is shipped inside the wash cavity of the machine. This screen must be in place during operation. It has been designed to perform two basic functions:
- Strain water that is circulating through the spray arms and pump assembly.
- A basket to catch broken glass, or heavy solids that may plug the impeller.
Set the machine in place, and level from side-to-side and front-to-back.
Electrical 1
Single-phase 230 volt, 60 Hz dedicated circuit should be used to supply electrical energy to the PKHT24 Glasswasher (see specification sheet on page 4). This system requires three power wires, which include a current carrying neutral. An additional fourth wire must be provided for ground. Approximately 4-feet of 3/4 flexible conduit with power leads (L-1, L-2, Neutral and Ground) extending out of the conduit are provided for easily connecting the power at installation. The power connection must be located such that there is sufficient length of the flexible conduit remaining to permit the machine to be moved for cleaning.

DO NOT USE POWER CORD OR GFI OUTLET
This unit MUST BE hard-wired to a dedicated appropriately sized circuit breaker.
Plumbing 2
The machine is equipped with a 1/2" NPT connection located at the lower left-hand corner (facing the back) of the machine. A 140°F water line should be plumbed to this point (see specification sheet). The water line used must be of sufficient length and flexibility to permit the machine to be moved for cleaning.
1,2 All electrical and plumbing connections must be made by a qualified person who will comply with all available federal, state, and local health, electrical, plumbing and safety codes.

WARNING: California Prop 65 Notice
These products may expose you to chemicals including Chromium, which are known to the state of California to cause cancer and birth defects or other reproductive harm. For more information on whether a product in this list contains these chemicals, please refer to the specific product page at perlick.com. Or to find out more about Prop 65, go to P65Warnings.ca.gov.
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) flow rate and 60 gph (Gallons Per Hour) recovery rate. The pipe supplying the water must be 1/2 " minimum. The plumbing connection is located at the back of the machine. (See specification sheet on page 4).
The PKHT24 may be supplied with an optional drain pump for elevated drains. For floor 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 floor drain. If a drain pump is used with a floor drain, the drain hose must rise 12 to 16" before dropping to the floor 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 flow restriction. Rinse flow restriction will cause the booster tank to expand and contract causing metal flex, which will eventually crack the tank.
BETA Detergent And Rinse Dispenser
The built-in Beta Detergent and Rinse Dispenser has easy access for chemical settings behind the front kick panel. Both initial charge and recharge is factory pre-set. Basic settings for both detergent and rinse speed are 50%. Operating fine-adjustment screws on the dispenser can control the amount of chemicals drawn into chemical lines.
![graph TD A["DETERGENT SPEED"] --> B["50%-0%"] C["RINSE SPEED"] --> B B --> D["0%-50%"]](/content/2026/05/957593/images/1f4662e32b68fc0aeda0f5608535b51ae8bddb872bd430e1bf0592b38a9184de.jpg)
Safety-Temp Feature
The Safety-Temp feature assures the final rinse cycle is always at a consistent minimum of 180 degrees.
How it works: The Safety-Temp function operates off the fifth cam (labeled "SafeTtemp") on the timer assembly. When the cam timer assembly completes the wash cycle, and approaches the final rinse portion of the cycle, the Safety-Temp micro switch will drop into the cam slot and pause the cam timer assembly if the booster heater has not reached 180 degrees. The machine will remain in wash cycle mode until 180 degree rinse temperature is met, and at this time the cam timer will advance automatically into the rinse cycle and dispense 180 degrees rinse water over the dishes.
Note: If the Safety-Temp cam is not to be used, it becomes a spare cam.
Safety-Temp Installation Instructions
- Remove the 4 cam timer assembly (note wire colors and wire placement for all 4 cam timer micro switches) and install the 5 cam timer in its place.
- Place all wires removed from 4 cam timer assembly in the exact position on the 5 cam timer assembly.
- The cam timer motor receives (1) yellow wire and (1) white wire (re-connect the yellow wire only from the glasswasher harness to the motor).
- The Safety-Temp 5 cam timer assembly kit includes two white harnesses – connect the white wire with the female bullet connector to the timer motor, the stripped end to the #22/NC on the contactor, and the spade end to the center terminal on the fifth micro switch.
- Connect white wire with male bullet connector from the kit to the white wire with female bullet connector coming from glasswasher harness, stripped end to #21/NC on contactor, and the spade end to the top terminal on the fifth micro switch.

Booster Heater Setup
The booster tank must be filled with water before the heating element is energized. For this reason, the "High Limit Switch" has intentionally been disconnected at the factory and will require re-connection before the heating element will turn on.
Follow the procedure below to complete the initial installation:
- Close the door on the machine.
- Turn the Power switch to the "ON" position.
- Hold the "FILL" switch in until water overflows into the scrap tray.
- Turn the Power switch to the "OFF" position.
- Connect the blue wire with the disconnect, identified by a red tag, to the High Limit Switch, which is located behind the thermostat behind the front kick panel.
