Page 10: Water Supply Connection
PTK Series Polyethylene Pump Tank Station with Checkmate Control System Install ‘from process” line into the back 1/3 section of the hot side of the tank through the provided opening. Note: all lines returning to the tank should extend below the water level, approximately 1.5 feet from the bottom of the tank. Note: on a single pump system, the return line will connect directly to the chiller or tower cell inlet. -

PTK Series Polyethylene Pump Tank Station with Checkmate Control System conductor cable rated for the motor’s power requirements and install according to local codes. Some motor starters may require a separate 110 volt line be installed. GENERAL 1. Make certain all ground connections to the unit are properly affixed. Make certain power conductor, disconnecting means, and fusing are properly sized according to the unit’s power supply requirements. Make certain all electrical connections are tightly affixed. Any loose wiring connections must be tighten before engaging the power supply. -

Page 13: General
PTK Series Polyethylene Pump Tank Station with Checkmate Control System GENERAL Failure to follow the factory required operation procedures may adversely affect the unit’s ability to adequately distribute process water and may create a hazardous operating condition which may result in unit damage and serious operator injury. The operator must verify that all plumbing and electrical connections are in accordance to section 2 of this manual and local codes. - Page 14 PTK Series Polyethylene Pump Tank Station with Checkmate Control System Open as many process connection valves as possible to establish a water flow path. Motor Rotation for Process Pump. Activate the electrical power to the unit. Turn the process pump ‘on’ momentarily and then ‘off’ again. Observe the shaft of each motor. As the shaft slows to a stop, its rotation can be determined. Correct rotation is clockwise when viewed from the rear of the motor.
- Page 15 PTK Series Polyethylene Pump Tank Station with Checkmate Control System Note... in initial start up, the water use points may not be sufficient to fully load the motor. As you add use points, you should recheck the amp draw on the motor and adjust the discharge valve as needed to prevent overloading the motor. Repeat the procedure with the tower/evaporator pump.

PTK Series Polyethylene Pump Tank Station with Checkmate Control System Temperature gauges. On systems without the digital annunciator display, temperature gauges are mounted on both sides of the tank. On systems with the Checkmate display, temperature is indicated on the digital display window. - Page 17 PTK Series Polyethylene Pump Tank Station with Checkmate Control System Top Operators are provided for pump, fan control, and system start and stop. An emergency stop operator is provided for emergency system shut down. Top Operator for Pump Control To start the pump turn the switch to “ON”.

Page 20: Pump Seal Service
PTK Series Polyethylene Pump Tank Station with Checkmate Control System PUMP SEAL REPLACEMENT The unit pump seal is a carbon/niresist shaft seal assembly including a stationary member, rotating member and tension spring (figure 4.2A). The operator can determine the pump seal is leaking when fluid is identified leaking from the pump case adapter. - Page 21 PTK Series Polyethylene Pump Tank Station with Checkmate Control System The motor shaft is free to rotate, but must be secured to remove the impeller. To secure the motor shaft, insert a flat bladed screw driver in slot to hold the shaft stationary (figure 4.2E). Locate and remove impeller locking screw (figure 4.2F). Using a socket and ratchet, the impeller retaining screw can be removed. Once the retaining screw is removed, the impeller can be “unthreaded” from the motor shaft to expose the...
- Page 22 PTK Series Polyethylene Pump Tank Station with Checkmate Control System Clean pump casing, cavities, impeller and O-ring before reassembly. Mate the motor and motor adapter to the pump casing. Reinstall the pump casing bolts. Reconnect the water cooling lines to the pump adapter (if applicable).

Page 23: Solenoid Valve Service
PTK Series Polyethylene Pump Tank Station with Checkmate Control System SOLENOID VALVE SERVICE Units with the optional electric water make-up system use a solenoid valve controlled by the float switch for water make-up. The operator can determine the solenoid valve requires service when the tank does not ‘make-up’ as required. -
Page 24: Instrument Calibration
PTK Series Polyethylene Pump Tank Station with Checkmate Control System DISPLAY CALIBRATION There are two calibration potentiometers on the back of Checkmate instrument. One potentiometer calibrates the To Process probe and the other potentiometer calibrates the other probes (From Process, To Tower, From Tower). - Page 25 PTK Series Polyethylene Pump Tank Station with Checkmate Control System Repeat Step 3 until the temperature displayed by the Checkmate agrees with the independent temperature meter. Note: When the From Tower probe is calibrated all the remaining probes are calibrated.

Page 28: Typical Press Drop
PTK Series Polyethylene Pump Tank Station with Checkmate Control System TYPICAL PRESS DROP The design of the unit-to-process hook up is key to optimizing the capability of the heating/cooling system. Selecting proper pipe ID’s, minimum run lengths, minimum elbows, tees are all important to creating a low pressure drop thus a high flow rate. This diagram schematically contains piping and valving details which may not be needed in all cases. However, for molding installations requiring maximum flexibility, a relatively... -
Page 29: Checkmate Second Set Point Guide
PTK Series Polyethylene Pump Tank Station with Checkmate Control System CHECKMATE SECOND SET POINT GUIDE All Checkmate CPU boards with firmware version 1.07 or later have the second set point function (displayed as ALT SP). Second setpoint allows for an alternate setpoint from the primary setpoint to be initiated from a remote point. And example is lowering the setpoint in the winter to use as chilled water and bypassing the chiller system. - Page 30 © 2019 TEMPTEK, INC. RE 09/30/2019 Page: 30...
