4 Installation 4.2 Electrical requirements 4.2 Electrical requirements Introduction This section outlines the electrical requirements for MultiTemp IV Thermostatic Circulator. WARNING Access to power switch and power cord. The power switch must always be easy to access. The power cord must always be easy to disconnect. WARNING Protective ground. MultiTemp IV Thermostatic Circulator must always be connected to a grounded power outlet. WARNING Do not use MultiTemp IV Thermostatic Circulator if it is not working properly, or if it has suffered any damage, for example: damage to the power cord or its plug damage caused by dropping the equipment damage caused by splashing liquid onto it The construction of the MultiTemp IV Thermostatic Circulator provides protection against the risk of electrical shock by grounding appropriate metal parts. The protection will not function unless the power cord is connected to a properly grounded outlet. The MultiTemp IV Thermostatic Circulator unit is intended for use on a dedicated outlet. All units are equipped with a C14 main power inlet and a 20 A circuit protector. Note: If the circuit protector trips, allow the unit to cool before resetting the circuit protector. Restart the unit. Contact us if it activates again. Refer to the nameplate on the rear, upper-left-hand corner of the unit for specific electrical requirements. Voltage deviations of ± 10% are permissible. The wall outlet must be rated as suitable for the total power consumption of the unit. MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD 35
4 Installation 4.3 Plumbing requirements 4.3 Plumbing requirements Introduction This section outlines the plumbing requirements for MultiTemp IV Thermostatic Circulator. CAUTION Never connect the process fluid lines to your facility water supply or any pressurized liquid source.

4 Installation 4.4 Fluid considerations 4.4 Fluid considerations Introduction This section outlines the fluid considerations for MultiTemp IV Thermostatic Circulator. WARNING Flammable liquids. MultiTemp IV Thermostatic Circulator is not approved to handle flammable fluids. WARNING Handling and disposal of liquids other than water should be done in accordance with the fluid manufacturers specification and/or the MSDS for the fluid used. WARNING The user is always responsible for the fluid used. Never use corrosive or flammable fluids with this unit. WARNING Ensure, when selecting the heat transfer fluid, that no toxic gases can be generated. Inflammable gases can build up over the fluid during usage. CAUTION Always adjust the unit's software to the fluid used. MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD 39
4 Installation 4.4 Fluid considerations NOTICE Water/ laboratory grade ethylene glycol mixtures require top-offs with pure water, otherwise the percentage of laboratory grade ethylene glycol will increase resulting in high viscosity and poor performance. Do not use bath fluids that: are very highly viscous (much higher than 30 mpas at the respective working temperature) have corrosive characteristics or tend to break down at high temperatures For fluid selection consider application requirements, operating temperature range, material compatibility, safety concerns, and environmental issues. Refer to Chapter 8 Reference information, on page 85 for suitable fluids. 40 MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD
4 Installation 4.5 Filling requirements 4.5 Filling requirements Introduction WARNING Before using any fluid refer to the manufacturer s MSDS and EC safety data sheets for handling precautions. This section outlines the filling requirements for MultiTemp IV Thermostatic Circulator. Note: Ensure the reservoir overflow located on the rear of the unit is connected to a suitable drain. 1 Start with 2.8 liters of fluid. Lift up on the fill panel on the front of the unit to remove it. 2 Insert the supplied funnel into the hose and slowly add fluid. Note: Due to the unit's plumbing configuration, adding fluid too quickly may result in overfilling - the fill level indication lags the actual amount added. 3 Ensure the fluid contacts the side of the funnel first, A when pouring fluid into the funnel. Pouring the fluid into the center of the funnel, B, will cause air pockets and substantially slow down the filling time. A B MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD 41
4 Installation 4.5 Filling requirements 4 Using the fill lines, verify the desired fluid level. MAX MIN Since the reservoir capacity may be small compared to your application and air may need to be purged from the lines. Have extra cooling fluid on hand to keep the system topped off when external circulation is started. CAUTION Avoid overfilling, fluids expand when heated. 42 MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD
4 Installation 4.6 Draining 4.6 Draining Introduction This section outlines how to drain MultiTemp IV Thermostatic Circulator. WARNING Always use appropriate personal protective equipment during operation and maintenance of MultiTemp IV Thermostatic Circulator. CAUTION Before draining any fluid refer to the manufacturer s MSDS and EC safety data sheets for handling precautions. CAUTION If leakage occurs from the drain tubing on the front panel, hot fluid may cause harm to personnel. CAUTION Drain the unit before it is transported and/or stored in near or below freezing temperatures. 1 Lift up on the fill panel on the front of the unit to remove it. 2 Pull the fill hose off the clips securing it to the unit. MultiTemp IV Thermostatic Circulator Operating Instructions 28-9969-20 AD 43
